Tucked at the base of Mount Diablo in eastern Contra Costa County, Clayton is a small, close-knit city with a pride of ownership that shows in its well-kept neighborhoods and backyard pools. The inland location means long, hot summers with temperatures that rival the Central Valley — ideal pool weather, but tough on water chemistry and pool equipment. Pinnacle Pool & Spa Services serves Clayton homeowners with the same level of certified, experienced pool care we bring to every community, from routine leak detection to full system upgrades and resurfacing.
We specialize in advanced pool and spa leak detection and underground swimming pool plumbing repair for complex systems. Includes diagnostic reporting and analysis.
We can find pool plumbing leaks under concrete pool decks, at the equipment, in the pool surface, waterfalls … you name it, we will find that leak in your pool and fix it!
A properly maintained swimming pool and spa system is more efficient, which reduces cost and saves water. We install and upgrade all popular pool system components.
Pool resurfacing is one of the most common and affordable ways to give your pool a facelift. The addition of waterline tiles is a popular way to enhance its appeal.
Eye irritation after swimming is often blamed on chlorine, but in most cases low pH is the actual culprit — when water in Clayton is too acidic it disrupts the eye’s natural chemistry. Testing and adjusting your pH to the correct range of 7.2–7.6 typically resolves the problem quickly.
Clayton’s water supply carries mineral content — calcium and magnesium in particular — that accumulates on pool surfaces, tile, and equipment fittings over time. The most visible sign is typically a white or gray scale line at the waterline tile, which worsens if left unmanaged. Regular water chemistry testing and balancing — specifically monitoring calcium hardness and total alkalinity — keeps scaling in check. If scale has already built up significantly, tile cleaning or a mild acid wash may be needed to restore the surface. Our weekly maintenance plans include comprehensive water testing and chemistry balancing at every visit.
Summers near the base of Mount Diablo are hot and dry. When temperatures climb into the 90s and above, chlorine breaks down faster, algae risk increases, and evaporation speeds up noticeably. We recommend increasing pump run time during summer — typically 8–12 hours a day — and testing water chemistry more frequently between service visits. Home test kits used every few days during July and August are a good way to catch early-stage algae before it becomes a full bloom. Our maintenance plans are built to account for the East Bay’s seasonal demands.
Weekly professional testing is the standard we recommend — and for good reason. While home test strips and drop kits are useful for quick checks on pH and free chlorine, they only provide a partial picture. Professional water testing covers a broader panel: calcium hardness, total dissolved solids, cyanuric acid, phosphates, alkalinity, and more — parameters that home kits miss but that have a significant impact on water safety, surface integrity, and equipment longevity. At every service visit, we test the full panel and make adjustments based on the complete chemistry profile, not just the basics.
Yes. We install and upgrade pool equipment including pumps, filters, heaters, automation systems, and sanitization equipment. If your pool is running on older equipment, an upgrade can significantly improve efficiency, reliability, and water quality. Variable-speed pumps in particular offer substantial energy savings over single-speed models and are now required by California energy code for most new and replacement pump installations. Learn more about our equipment install and upgrade services.
Rough or peeling plaster, persistent staining that doesn’t respond to chemical treatment, calcium deposits etched into the surface, and widespread cracking or pitting are all signs that resurfacing is overdue. For older pools in Clayton that haven’t been resurfaced in 10–15 years, a fresh application of a premium finish can be one of the most impactful improvements available. We offer premium options including Aquabella, PebbleTec, and WetEdge. Learn more about our resurfacing and renovation services.
Absolutely. Clayton has a mix of housing vintages, and some older properties have pool plumbing and equipment that hasn’t been updated in many years. Aging PVC fittings, corroded equipment connections, outdated filtration, and galvanized pipes are all issues we address regularly. If your pool has been running on its original plumbing for decades, a plumbing inspection is a worthwhile investment — particularly since older fittings are among the most common sources of slow leaks.

Had a leak in my pool and needed leak detection and repair. Several of the companies I contacted via Yelp said they don’t do leak detection… Cooper came out and found the leak and then scheduled a repair. The repair was done quickly and the price was less than those quoted by other companies.
Norman J.Yelp, 2025Out of the four contractors that we met with, he was the most personable. He has excellent communication skills and will respond at all times of the day. He addressed every question and concern we had and ensured all issues were rectified.
Melinda D., Elk GroveYelp, 2024Cooper was so helpful for fixing our pool leak. From beginning to end – identifying source of leak, fixing it, patching up concrete – he was an efficient expert who clearly knew what he was doing… He saved us so much time and angst.
Jessie Y., San FranciscoYelp, 2025Outstanding service!!! They are simply amazing and do exceptional work. In addition they were extremely well priced and provided me with the highest quality materials that will last 20 years. PLEASE USE THEM!!! Support small businesses like them that do great work. Pinnacle Pools seems motivated not by money but by customer service. They considered what… I …the customer wanted … They had great recommendations to my project… motivated, not out of profit, but because it’s the right thing to do.
Patrick H., SacramentoYelp, 2022Best and most knowledgeable pool person that I’ve ever had work on my pool. He fixed my pump and fixed a leak in the pool. Fast, efficient and affordable.
Steve N., LoomisYelp, 2023Cooper came right out to look at a leaking pool motor. He gave us an estimate for the time and the work, and he returned to do what needed to be done… He had all the equipment and seals he needed to finish the job in about an hour. Other places we’ve used always have to delay to get parts.
Lee S., San FranciscoYelp, 2023Incredibly fast (even though they were very busy pinnacle pool was able to make a leak detection service visit and repair within less than 30 minutes to Folsom area), knowledgeable, and honest service. Absolutely glad I found them.
Corey K., SacramentoYelp, 2024Cooper at Pinnacle Pool and Spa recently replaced my pool heater and I can’t thank him enough. He quoted me a super reasonable price and although it ended up being more work, he never mentioned any additional charges. Despite the install being a bit of a pain, he didn’t cut any corners.
Matt Johnson, Walnut GroveGoogle, 2023Cooper showed up right on time, quickly spotted the issue with my old pump, and even found a leak in the water line I hadn’t noticed. He knocked out the repairs in a single day, and the price ended up being less than the other ballpark bids I’d collected. Since then my pool has been holding water like it’s supposed to!
Eddie P., El Dorado HillsGoogle, 2025I was losing a ton of water and having to add a lot of water every day. Cooper was able to come out quickly and inspect my pool, he performed pressure tests to check the plumbing and also did a dye test throughout the pool… he ended up finding and repairing multiple leaks and at a reasonable price!
