Pleasant Hill occupies a central position in Contra Costa County between Walnut Creek and Concord, with a solid base of mid-century and post-war homes whose pools are entering a critical maintenance window. Many of these pools have original plumbing, aging equipment pads, and plaster surfaces well past their intended lifespan. Pinnacle Pool & Spa Services works with Pleasant Hill pool owners to address both immediate issues — leaks, failing equipment, water chemistry problems — and the longer-term investments like resurfacing and system upgrades that protect the value of the pool for years to come.
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.
The lifespan of your swimming pool finish depends on the material and how well water chemistry is maintained over the years. Standard plaster typically holds up for 7–10 years, quartz aggregate for 10–15 years, and pebble finishes — the most durable option — can perform well for 15–20 years or more with proper care.
Yes, to a degree. Water in the Pleasant Hill area carries moderate mineral content that gradually accumulates as calcium scale on tile, pool surfaces, and equipment fittings. That white deposit along the waterline is calcium scale — common in East Bay pools — and consistent water chemistry management keeps it from becoming a serious problem. Our weekly maintenance plans include calcium hardness testing and balancing at every visit.
Pleasant Hill sits in the Contra Costa interior and sees hot, dry summers with temperatures regularly hitting the 90s. Heat accelerates chlorine loss and increases algae risk. Running your pump 8–10 hours daily during peak summer and testing chemistry more frequently between service visits — home testing every few days in July and August is worthwhile — helps keep the pool in good shape through the hot months. Learn about our maintenance plans.
Pleasant Hill has a mix of housing from the 1960s through more recent development, and older pools in the area come with predictable patterns of wear: plaster surfaces that have roughened, peeled, or stained; aging equipment running less efficiently than it should; plumbing fittings that may have corroded; and light fixtures that may not meet current safety standards. A professional inspection can identify what genuinely needs attention versus what still has serviceable life — and help you prioritize accordingly. Learn about renovation options, repair services, and equipment upgrades.
Signs include filling the pool more often than usual, wet areas in the yard or near the equipment pad, air bubbles in the return jets, or chemical levels that drop without explanation. A simple bucket test can help distinguish a genuine leak from normal evaporation: place a filled bucket on the first pool step and compare water-level drop between the pool and the bucket over 24 hours. If the pool is losing significantly more, it’s time to investigate. We use professional electronic listening devices, dye testing, and pressure testing to locate leaks without draining the pool. Our At Home Diagnostics guide is also a useful first step. Learn more about our leak detection services.
If your pool surface is peeling, rough, or stained beyond what chemical treatment can fix, resurfacing is the right solution. We offer quartz finishes like Aquabella and pebble finishes like PebbleTec, both of which significantly outperform standard plaster in durability and appearance. We can also update your waterline tile at the same time for a clean, complete refresh. Learn more about our resurfacing and renovation services.
Yes. Our weekly maintenance plans include skimming, brushing, vacuuming, basket emptying, equipment inspection, and full water chemistry testing and balancing. Consistent professional maintenance is the most cost-effective way to prevent expensive repairs, extend the life of your surfaces and equipment, and keep your pool clean and safe through the East Bay’s long pool season.

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!
