Renovation has emerged as the most dependable growth channel in the swimming pool sector. While new construction cycles fluctuate with economic conditions, the installed base of aging pools continues to represent a stable and scalable revenue stream. Homeowners are choosing to reinvest in existing backyards, upgrading aesthetics, replacing aging equipment, and improving energy efficiency. But beyond visible improvements, many clients are asking a new set of questions: Can I control it from my phone? Can it alert me if something goes wrong? Can it run more efficiently? Those questions are opening the door to automation as a natural extension of renovation — not as a complex luxury system, but as a practical, revenue-generating upgrade.

For forward-thinking pool professionals, integrating automation into renovation projects is no longer a luxury add-on — it is a strategic modernization tool that increases project value, improves operational efficiency, and strengthens long-term client retention. As smart-home technology becomes standard indoors, automation is rapidly becoming the next expectation outdoors.

The Automation Shift: Meeting Evolving Homeowner Expectations

Renovation projects present more than an opportunity to refresh a pool’s appearance — they provide a strategic moment to modernize how the entire system operates. With millions of existing pools built before smart controls became mainstream, there is significant untapped potential sitting on equipment pads across the country. Homeowners already manage thermostats, lighting, and security systems from their smartphones; naturally, they are beginning to expect the same level of control over their pools and spas. For pool professionals, that shift in expectation creates a clear opening to introduce automation as part of a comprehensive renovation strategy.

John MacDonald, owner of Your Pool Guy Inc in Doylestown, Pennsylvania says his customers routinely ask him about automation for their pools. “Most customers start the automation discussion by asking if there is a way to control their pool water temperature remotely. Then they ask me if there is an app for that.” MacDonald says his clients are mostly interested in controlling their heaters, their pool lights and their water chemistry.

The smart phone has driven the consumer’s desire to control all the elements of their home from anywhere, all in the palm of their hand. Exterior landscape lights, pool lights, hot tub and pool temperatures, and control over pool and hot tub water chemistry, all manageable through their mobile devices. “I’m a pool service professional but I know that to ensure my client’s satisfaction with their pool and outdoor living space, providing them with simple automation will help ensure my clients are happy because they have a trouble-free, easy to maintain pool,” explains MacDonald. “Automation simplifies the maintenance of the homeowner’s backyard so pool owners can make sure the pool is put to bed right before they fall asleep, without having to go outdoors to check.”

Keep It Simple: Pool Owners Prefer Streamlined Automation

Simpler automation systems like the Tild pool automation system, tend to be very effective for most customers. Intuitive, easy-to-operate systems are key to keeping customers happy. These systems offer enough features to satisfy the homeowner’s needs while remaining simple enough to avoid requiring technical support after installation. MacDonald says that the simpler automation systems are the most effective for the majority of his customers. “The simple automation systems that are intuitive to operate seem to really make customers happy,” explains MacDonald. “They just need to have enough of what the homeowner wants but also simple and intuitive enough that they don’t need any technical help after the installation.”

Control system interfaces have also become more user-friendly, even as their capabilities expand. For example, the Tild pool automation system comes equipped with the Vigipool app, that can be easily downloaded to the client’s smart phone. Consumers are comfortable with apps on their phone, whether it’s their home security system, lighting or streaming services. In fact, consumers are excited to use an app on their phone to control the temperature, lights and water chemistry of their pool.

Automation Pays for Itself

Automation simplifies chores associated with pool and hot tub ownership and brings cost-saving benefits. Timers for outdoor and pool lights help reduce electricity costs, as does regulating pool and spa water temperatures. Automated pool and hot tub water chemistry dosing and control, like the Oxeo ORP and Phileo pH feeders, prevent overdosing or imbalance, minimizing the need for excessive chemical use and reducing overall expenses. Maintaining balanced pool water chemistry is especially critical for plaster pools, as unbalanced chemistry can lead to costly repairs. Additionally, having a compact, user-friendly pH controller with app-based notifications like the Phileo pH is ideal solution for clients with pH imbalances caused by salt chlorine generators. Improper pH levels lead to scale build-up on the salt cell assembly, which can cause the chlorine generator to shut off.

“Many of my clients have salt chlorine generators and are regularly confronted with their salt-system shutting down as a result of pH problem in their pool water,” explains MacDonald. “One of the most frequent calls I receive is from clients reporting that their salt chlorine generator isn’t working. They don’t realize that they haven’t taken the time to maintain the proper pH levels in the pool water and we all know this leads to scale build up on the salt cell assembly which shuts off the chlorine generator.”

MacDonald likes to recommend and install a pH automation controller that measures and doses the pool water to maintain the proper pH level. “I can’t be at the pool every day ensuring the pH is in the right range, so I like to recommend CCEI’s Phileo pH controller because it’s so compact and easy to use,” says MacDonald. “It’s just a little box about 3” x 4” in size so it fits on any equipment pad and it comes with the app so clients are notified if the water goes out of range so they can go add acid in to the container or similar. It offers the chemical automation that most customers need and want.”

Pool professionals agree that automation systems can help avoid the problems that can quickly increase the operating costs of a pool. Automation doesn’t take away work from service professionals as there are still always tasks to complete. But automation systems like the chemical controllers and feeders help between service calls to ensure all systems are operating correctly.

Automation systems also offer valuable data. Service professionals can identify issues such as an imbalance in pH or if a light is not working. Being able to discuss issues with customers, rather than a generic inquiry such as “How is everything in your backyard?” provides a significant competitive advantage for service companies.

Many pool professionals agree that offering and installing simple automation systems helps modernize the pool for customer but more importantly helps them stand out from their competitors which can be a real game changer for many independent pool and spa professionals. “In addition to modernizing the pool, automation creates customer loyalty for our business, as clients are empowered and truly feel they have a better, more modern pool if they can control it from an app on their phone,” says MacDonald.

A Competitive Edge That Keeps Clients Coming Back

Offering and installing simple automation systems like the Tild pool automation system helps modernize pools for customers while differentiating their businesses from competitors. Adding simple automation to renovation projects is one of the easiest ways to increase project value, differentiate from competitors, and deliver the modern convenience clients already expect inside their homes. Automation is a game-changer that fosters customer loyalty by providing a more modern pool experience.

Offering pool automation boosts customer satisfaction and excitement about their backyard investment. These systems simplify pool maintenance and make operating other components easier, even remotely. Now is the perfect time for pool professionals to start offering simple backyard and pool automation as a way to renovate pools that need an update. Beyond liners, decking, and lighting upgrades, integrating simple automation systems gives pool professionals a powerful way to modernize and renovate older pools, increase profits, and deliver the smart-home functionality today’s homeowners expect.

Chlorine gets a bad wrap.

Dry skin. Red eyes. That harsh “pool smell” people complain about the second they walk into a backyard or indoor pool.

That story is common enough, but it doesn’t really hold water. Because when a pool is dialed in properly, chlorine isn’t the thing people notice. It’s only when the chemistry starts to slip that all those issues show up.

The truth sits right in the middle—and if you’re constantly around pools, understanding that nuance matters more than most people realize.

Because while chlorine is the backbone of modern pool sanitation, it’s also one of the most misunderstood chemicals when it comes to swimming pools.

And here’s the part most people don’t really get: it’s not just about chlorine itself—it’s what happens after it starts doing its job.

Chlorine Isn’t the Problem—Until It Becomes One

Let’s start here: properly balanced chlorine is not the enemy.

In fact, it’s the reason pools are even usable in the first place. It kills bacteria, neutralizes contaminants, and keeps water safe for human use. Health authorities consistently point out that when maintained within proper ranges, it’s not associated with harmful effects.

But chlorine doesn’t exist in a vacuum.

The second it hits organic matter—sweat, sunscreen, urine, body oils—it reacts. And that reaction creates a whole different class of compounds known as disinfection byproducts, most notably chloramines.

That’s where things start to get interesting.

That “Chlorine Smell”? That’s Actually the Problem

Here’s a quick reality check you can drop on any homeowner:

Think of your pool like a kitchen.

Free chlorine is your cleaning crew.
Chloramines are what happens when that crew gets overwhelmed and starts leaving behind dirty rags instead of actually cleaning.

Here’s what’s going on in plain English:

When your pool is “healthy,” chlorine is actively killing contaminants—sweat, sunscreen, body oils, urine, all the stuff people bring into the water. When chlorine does its job properly, it finishes the job and stays effective.

But when a pool is struggling, a few things usually happen:

• Not enough chlorine
• Poor circulation
• Dirty filter
• Heavy bather load
• High heat / sunlight burning chlorine off

Now the chlorine can’t keep up.

Instead of fully destroying contaminants, it only partially reacts with them—especially nitrogen-based stuff like sweat and urine.

That partial reaction creates chloramines.

And here’s the key:
Chloramines are basically used-up chlorine that’s now weak and smells bad

So the worse your pool condition gets, the more this cycle feeds itself:

1. More contaminants enter the water
2. Not enough strong chlorine to handle it
3. More partial reactions happen
4. More chloramines form
5. Water gets cloudy, smells “chlorine-y” (ironically), and irritates eyes
6. Now your chlorine is even less effective

It’s like your cleaning crew switching from disinfectant to just wiping things around with a dirty sponge.

That “strong chlorine smell” people talk about?
That’s not clean water—that’s chloramines building up.

What It Actually Does to the Body

Let’s break it down in real-world terms—the stuff people actually feel after swimming.

Skin: Dry, Tight, Irritated

Chlorine strips natural oils from the skin. That’s not a theory—it’s literally how it works as an oxidizer. The longer the exposure, the more moisture gets pulled out, leading to dryness, itching, and irritation.

For swimmers, that shows up as:
• Dry, flaky skin
• Redness or irritation
• Worsening of eczema or sensitive skin

For pool techs? Well, it’s why their hands look like they’ve been sanding drywall for 20 years.

Eyes: Burning, Red, and Watering

Again, not chlorine itself—chloramines.

When these compounds off-gas into the air (especially in indoor pools), they irritate the eyes and mucous membranes.

That classic “red eye” look after swimming? That’s a chemistry issue.

Lungs: The One Nobody Talks About Enough

This is where things get more serious.

Chloramines don’t just sit in the water—they gas off into the air above the pool surface. In poorly ventilated environments (think indoor facilities), that exposure can irritate the respiratory system.

We’re talking:
• Coughing
• Wheezing
• Chest tightness
• That “chlorine cough” you hear about

There’s also research linking repeated exposure—especially in competitive swimmers—to increased rates of asthma and airway irritation.

Now, is your average backyard swimmer at serious risk? No.

But for those working around this stuff every single day? That’s a different conversation.

Hair: Dry, Brittle… and Sometimes Green

The dryness comes from oxidation—same story as skin.

The green hair myth? That’s actually copper oxidation, not chlorine. But chlorine is what creates the conditions that allow it to happen.

Teeth: Yeah, Even That

Long-term exposure—especially in improperly balanced water—can contribute to enamel erosion and staining, sometimes referred to as “swimmer’s calculus.”

Not common for casual swimmers, but something you’ll see in high-frequency exposure scenarios.

The Bigger Picture: It’s About Byproducts, Not Chlorine

Here’s the takeaway most people miss:

Chlorine itself isn’t what causes most of the issues people complain about.

It’s the byproducts created when chlorine has to work too hard.

That’s why poorly maintained pools feel worse—even if they technically have chlorine in them.

And it’s also why a properly balanced pool with the right free chlorine, low combined chlorine, and good circulation feels completely different.

Having A Little Know-How Comes In Handy

Everything we just talked about? It’s controllable. Not eliminated—but managed. And the folks who understand this are the ones having the best swim experience.

Here’s what actually makes a difference:

• Keeping combined chlorine low (breakpoint chlorination matters)
• Proper circulation and filtration
• Encouraging pre-swim showers (huge, underrated)
• Ventilation in indoor environments
• Regular oxidation/shocking to eliminate chloramines

Fun fact: a massive percentage of swimmers skip showering before entering the pool—which means chlorine has to burn through more contaminants, creating more byproducts in the process.

So yeah… sometimes the problem isn’t with chemistry—it’s with swimmers.

The Core Chemistry Ranges To Target

Most people aren’t chasing perfection—they’re keeping water in a range where it behaves consistently. In a typical chlorine pool, that means maintaining free chlorine around 2–3 ppm, keeping pH in the 7.4 to 7.6 sweet spot, and holding total alkalinity between 80 and 120 ppm so the system stays stable. Calcium hardness generally lands between 200 and 400 ppm depending on the surface, while cyanuric acid sits around 30 to 50 ppm in most outdoor pools, sometimes higher in salt systems. Combined chlorine, or chloramines, should ideally be zero—anything over 0.5 ppm is a sign the pool is starting to struggle.

What Happens When the Water Falls Out of Balance

When chlorine drops too low, the water is no longer protected. It starts dull, turns cloudy, and eventually gives way to algae while chloramines begin to build. On the flip side, excessive chlorine usually shows up as irritation—burning eyes, dry skin, and unnecessary wear on liners and equipment.

pH is where most problems begin. When it falls too low, the water becomes aggressive, leading to corrosion and that sharp, uncomfortable feel swimmers notice right away. When pH climbs too high, chlorine loses effectiveness, which opens the door to cloudy water, scaling, and the slow buildup of problems that don’t resolve on their own.

Total alkalinity acts as the buffer for all of this. If it’s too low, pH becomes unpredictable and difficult to control. If it’s too high, pH tends to drift upward constantly, making the pool harder to manage over time.

Calcium hardness affects the pool surface more than anything. Low calcium creates “hungry” water that pulls minerals out of plaster, while high calcium leads to scale buildup on tile, heaters, and salt cells—often accompanied by cloudy water that refuses to clear.

Cyanuric acid is one of the most misunderstood factors. Without enough of it, chlorine gets burned off by sunlight almost as quickly as it’s added. With too much, chlorine becomes far less effective, creating situations where test results show adequate levels, but algae still appears.

Chloramines tie it all together. When they show up, it’s a clear signal that chlorine isn’t finishing its job. That’s when you get the strong smell, the irritation, and the sense that the water just isn’t right.

The Right Way To Think About It

At the end of the day, most people who are managing a pool’s chemistry aren’t looking at these numbers in isolation. Chlorine is the worker, pH determines how effective that worker is, cyanuric acid protects it from the sun, and alkalinity keeps the entire system from swinging out of control.

When those elements are in line, the pool runs clean and predictable. When they’re not, every visit turns into a problem-solving exercise.

Buying a home with a pool can almost feel like you hit the jackpot—until you realize that the swimming pool is its own ecosystem with its own set of rules, maintenance needs, and potential headaches. A backyard pool can absolutely elevate a property, but if you don’t know what you’re looking at, it can also turn into an expensive surprise. The key is understanding what to look for before you close, not after you’re already holding the keys.

You already called out some of the big visual red flags—loose tiles, green water, low levels, and structural cracks. Those are the obvious ones. But the real story usually lives just beneath the surface and over on the equipment pad.

Let’s walk through the top pool-related issues home buyers need to be aware of so you don’t inherit someone else’s problem project.

Structural Integrity Beyond the Obvious

Hairline cracks happen. That’s normal. But not all cracks are created equal. What you want to pay attention to are structural cracks—especially ones that run horizontally, widen over time, or show signs of movement.

Cracks in steps, benches, or along the bond beam (top edge of the pool) can indicate shifting soil, poor construction, or long-term neglect. If the pool is losing water and there are visible cracks, that’s a double whammy—now you’re talking structural repair plus leak detection.

Also look for signs of previous patchwork. If you see multiple areas that have been repaired or resurfaced inconsistently, that could mean ongoing issues rather than a one-time fix.

Pool Surface Condition (Plaster, Pebble, Vinyl, Fiberglass)

The interior finish tells you a lot about how the pool has been maintained. Plaster that feels rough, stained, or etched is usually the result of poor water chemistry over time. Pebble finishes should be uniform—if they look worn down or patchy, resurfacing could be on the horizon.

Vinyl liner pools have their own issues—wrinkles, fading, or brittleness are signs the liner is nearing the end of its life. Fiberglass pools should be smooth and glossy; dull or chalky finishes could indicate oxidation or improper care.

Resurfacing isn’t a minor expense, so this is one of those things you want to factor into your offer if it’s close.

Equipment Pad: The Heart of the System

One of the biggest mistakes people make when buying a home with a pool is that they forget to look at the pool equipment first. This often proves to be a costly error. The equipment pad is where you’ll find out if the system is dialed in or held together with duct tape and prayers.

Here’s what to inspect:

Pump: Listen for grinding or whining noises. That usually means worn bearings or a failing motor.

Filter: Check for leaks, rust, or cracks. Ask when it was last cleaned or replaced.

Heater: Look for corrosion, especially if the home is near the coast. Heaters are expensive to replace.

Chlorinator or Salt System: Salt cells have a limited lifespan. If it’s older, you may be replacing it soon.

Automation System: If there’s a control panel or app-based system, test it. Make sure it actually works.

A clean, organized equipment pad is usually a good sign. If it looks chaotic, poorly plumbed, or neglected, that tells you everything you need to know about how the pool has been cared for.

Circulation and Flow Issues

Even if the water looks okay during a showing, circulation problems can be hiding underneath. Poor circulation leads to algae growth, cloudy water, and inconsistent chemical distribution.

Watch for:

Weak return jets
Dead spots where debris collects
Air bubbles in the pump basket
Water not reaching skimmers properly

These can point to suction leaks, clogged lines, or undersized equipment. None of those are fun to deal with after the fact.

Signs of a Leak (Beyond Low Water Level)

Low water is one clue, but leaks don’t always present that clearly. Pools naturally lose some water to evaporation, especially in hot climates, so you need to dig deeper.

Look for:

Wet spots or sinking areas around the pool
Cracks in decking that seem to be shifting
Constant need to refill the pool
Air in the system (bubbles in returns)

A leak detection test might cost a few hundred bucks during escrow, but it can save you thousands if there’s an underground issue.

Decking and Drainage Problems

The area around the pool matters just as much as the pool itself. Poor drainage can lead to water pooling near the foundation or undermining the pool structure over time.

Watch for:

Uneven or lifting deck surfaces
Standing water after rain or heavy use
Cracks that run toward the pool
Deck material separating from the coping

This isn’t just cosmetic. Drainage issues can lead to bigger structural problems if left unchecked.

Coping and Tile Line Condition

The coping (the edge around the pool) and tile line take a beating from weather, chemicals, and constant water exposure. Loose coping stones or deteriorating grout can allow water to seep behind the shell, leading to bigger issues.

If tiles are falling off or the grout is crumbling, it’s usually a sign of long-term neglect rather than a quick fix situation.

Electrical and Safety Compliance

This is one area you don’t want to overlook. Pools involve electricity, water, and metal—bad combination if things aren’t up to code.

Make sure:

GFCI outlets are present and functional
Bonding wires are intact
Pool lights are working and properly sealed
There are no exposed or makeshift electrical connections

Older pools may not meet current code, and bringing them up to standard can cost real money.

Age and Remaining Life of Equipment

Everything on a pool has a lifespan. Pumps, heaters, filters, and salt cells don’t last forever. If the equipment is 8–12 years old or older, you should assume replacements are coming soon.

Ask for:

Installation dates
Service records
Any recent repairs or upgrades

If the seller doesn’t know, that’s already a signal.

Water Chemistry History

You can tell a lot about a pool just by testing the water. If levels are wildly off during a showing, that might mean the pool hasn’t been maintained properly.

Poor chemistry over time leads to:

Surface damage
Equipment wear
Algae growth
Scaling and staining

Even if it looks clean for the showing, bad habits tend to leave long-term damage.

Pool Size, Depth, and Usability

Not all pools are practical for every buyer. Some are too deep, too shallow, or oddly shaped for actual use.

Think about:

Is the depth appropriate for your family?
Is there usable space for lounging or playing?
Are steps and entries safe and accessible?

A pool that looks impressive but isn’t functional can become more of a burden than a benefit.

Permits and Compliance

Make sure the pool was built legally and permitted. Unpermitted pools can create issues with insurance, resale, and liability.

Also check:

Fencing requirements
Safety gates and alarms
Local compliance standards

You don’t want to inherit a compliance issue that becomes your problem.

What Sellers Should Be Providing to Smooth the Sale

When buying a home with a pool, one of the clearest signs of how well it’s been cared for is the documentation the seller can provide.

Pools make buyers nervous for a reason. Unknown condition, hidden issues, and lack of maintenance history can quickly turn a great backyard into a question mark. The more information a seller can provide, the easier it is to evaluate the pool with confidence.

Here’s what the seller should have ready:

Builder Information
Who built the pool? Was it a reputable company? If you’ve got original plans or documentation, that’s gold.

Service History
Provide records of regular maintenance. Show that the pool has been consistently cared for, not ignored until listing day.

Equipment Manuals
Buyers don’t want to inherit a system they can’t operate. Having manuals or even basic written instructions goes a long way.

Warranty Information
If any equipment is still under warranty, make that clear. Transferable warranties are a big plus.

Recent Repairs or Upgrades
Be transparent about what’s been done—new pump, resurfacing, tile work, etc. This builds trust and reduces negotiation friction.

Utility and Operating Costs
Give buyers a realistic idea of what it costs to run the pool monthly. This helps eliminate surprises.

Pool Service Contact
If you have a reliable service company, introduce them. Buyers love continuity, especially if they’re new to pool ownership.

Startup Instructions
A simple “how to run your pool” guide—timers, valves, cleaning schedule—can make a huge difference for a first-time pool owner.

Clean, Balanced Water
This sounds basic, but it matters. A clean, properly balanced pool during showings sends a strong signal that the pool has been maintained.

At the end of the day, buying a home with a pool isn’t just about the backyard lifestyle—it’s about inheriting a system. If that system is in good shape, you’re stepping into something awesome. If it’s not, you’re stepping into a project.

Do your homework, get a professional pool inspection during escrow, and treat the pool with the same level of scrutiny as the roof or foundation. Because when a pool goes sideways, it doesn’t mess around.

Does a Pool Add Resale Value?

Yes—but it depends on the market, the condition of the pool, and how well it’s maintained.

A 2025 study from Realtor.com found that homes with pools sold for a 54% premium—$599,000 versus $389,000 for homes without. While the so-called “pandemic pool premium” has cooled, pools still remain a strong selling point in many markets, especially in warmer climates.

“During the pandemic, people were looking for ways to get more enjoyment out of their homes, and this surge in demand for features like pools translated into a substantial ‘pool premium,’ where homes featuring a pool commanded significantly higher asking prices compared to their pool-less counterparts,” says real estate expert Hannah Jones.

That premium peaked in early 2022, but it hasn’t disappeared.

“Although price premiums have normalized, the presence of a pool continues to drive a premium and be a popular item to include in listings as a home or community feature,” Jones adds.

The catch? Condition matters.

In other words, buying a home with a pool can add value—but only if it’s been well maintained. Even an older pool with updated equipment can absolutely increase buyer appeal and help a home sell faster. But a neglected pool—green water, broken or outdated equipment, visible damage—can have the opposite effect, turning buyers off or becoming a negotiation point that drags the price down.
