Alamo is one of the most desirable communities in Contra Costa County, known for its large estate lots, mature landscaping, and custom backyard pools that become the centerpiece of the property. With warm, dry summers that regularly push into the 90s, a well-maintained pool isn’t a luxury here — it’s a way of life. Pinnacle Pool & Spa Services brings licensed, certified pool expertise to Alamo homeowners, whether you’re dealing with an aging plaster finish that’s well past its prime, a stubborn leak you can’t track down, or a system upgrade to meet California’s new heat pump requirements.
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.
Skim the surface of your pool daily when possible to prevent debris from breaking down and affecting your water chemistry. Brush the walls, steps, and floor at least once a week and vacuum on the same schedule — consistent care is your best defense against algae buildup and surface staining in your Alamo pool.
Water in the Alamo area tends to have moderate calcium and mineral content, which builds up over time on tile, pool surfaces, and equipment fittings. That familiar white residue along your waterline tile is calcium scale, and in a warm, low-humidity climate like Alamo’s, it can accumulate faster as evaporation concentrates minerals in the water. Regular water chemistry management — including monitoring calcium hardness and total alkalinity — keeps scaling under control. If buildup has already taken hold on your tile, cleaning or tile restoration may be needed. Our weekly maintenance plans include chemistry testing and balancing at every visit.
Alamo summers are hot and dry, with temperatures regularly pushing into the 90s and beyond. Heat accelerates chlorine loss, increases algae risk, and drives up evaporation — meaning your pool’s chemical balance needs more frequent attention during summer months, not less. We recommend testing water chemistry at home every few days during peak summer, running your pump 8–12 hours daily, and not skipping service visits during July and August. Our weekly maintenance plans are calibrated for the seasonal demands of the Contra Costa climate.
Yes. Many Alamo communities include homeowner associations that have specific guidelines for pool remodels, equipment placement, and construction timelines. We’re experienced working within HOA approval processes and can provide documentation, photos, and project descriptions to support your submission. We always recommend initiating HOA approval early — before scheduling any major renovation or resurfacing work — as timelines vary by association and can add weeks to a project start date.
Mature oaks, eucalyptus, and ornamental landscaping — common throughout Alamo — shed leaves, pollen, and debris into pools year-round. Beyond the obvious cleaning work, the bigger concern is phosphates: as organic material breaks down in the water, it releases phosphates, which are a primary food source for algae. Skimming as frequently as possible between service visits and keeping pump baskets clear significantly reduces this chemical burden. Our maintenance plans include debris removal, basket emptying, and phosphate monitoring as standard.
Common signs of a leak include needing to top off your water more than an inch or two per week, wet patches in the yard, air bubbles in the return lines, or chemical levels that drop faster than expected. Alamo properties with mature landscaping and older plumbing are worth monitoring closely, as tree roots can shift soil and stress underground pipes over time. Our team uses electronic listening devices, dye testing, and pressure testing to locate leaks precisely — without draining the pool. We also offer an At Home Diagnostics guide to help you do an initial check before scheduling a visit. Learn more about our leak detection services.
Alamo’s estate properties often feature large custom pools, and many are overdue for a meaningful upgrade. We offer full pool and spa remodeling including resurfacing with premium finishes like PebbleTec, Aquabella, or WetEdge; waterline tile replacement with options like AquaBlu glass tile; coping and deck work; LED lighting upgrades; and equipment modernization. A well-planned renovation can dramatically improve both the appearance and operating efficiency of your pool. Learn more about our renovation services or request a quote.

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!
