Moraga is a peaceful, close-knit community in the Lamorinda hills with an appreciation for understated quality and a strong sense of neighborhood. The hillside terrain and established landscaping that define many Moraga properties can make pool work more involved than in flatter communities, and not every contractor is equipped for it. Pinnacle Pool & Spa Services has the tools, experience, and problem-solving approach to handle Moraga’s more challenging pool environments — and the professionalism that fits the community.
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.
Skimmer bodies and light niche seals are among the most common leak points in residential pools, particularly in older Moraga pool construction where materials have had years to contract, expand, and crack. These are repairs we handle routinely, and in many cases they can be completed without draining the pool.
Like other East Bay communities, Moraga’s water carries mineral content that accumulates over time as calcium scale on tile, pool surfaces, and equipment. Regular water chemistry monitoring — particularly calcium hardness and total alkalinity — keeps scaling in check and protects your pool’s surfaces. If scaling has already built up noticeably on your tile, cleaning or tile restoration can address it. Our weekly maintenance service includes comprehensive chemistry testing and balancing at every visit.
Moraga sits in an inland valley that heats up considerably in summer, with temperatures regularly reaching the 90s. The surrounding hills can slow the marine layer that cools much of the coast, leaving Moraga with hot, dry summer afternoons that put real demands on pool chemistry. Heat drives chlorine demand up and creates favorable conditions for algae. Running your pump 8–10 hours daily during summer and testing chemistry between service visits are good practices. Our maintenance plans are designed with the East Bay’s warm summers in mind.
Mature trees and dense landscaping — characteristic of Moraga’s residential neighborhoods — deposit leaves, flowers, pollen, and other organic debris into the pool throughout the year. As this material breaks down, it releases phosphates into the water, which are a primary food source for algae. Frequent skimming between service visits and clearing pump baskets regularly makes a meaningful difference in chemical stability and water clarity. Our maintenance plans include debris management and phosphate monitoring as standard.
Yes. Hillside and sloped properties in Moraga can present specific challenges: shifting soil from seasonal wetting and drying, drainage management around the pool surround, and the long-term integrity of retaining walls and pool structures. Soil movement — whether from seasonal cycles, tree roots, or minor seismic activity — can stress underground plumbing over time, creating slow leaks that are difficult to detect without professional equipment. Periodic inspection of the pool surround and plumbing is worthwhile on hillside properties. Learn more about our leak detection services and plumbing repair services.
We offer full renovation services including resurfacing with premium finishes like PebbleTec, Aquabella, and WetEdge; waterline tile replacement with options like AquaBlu glass tile; coping and deck upgrades; LED lighting; and equipment modernization. For Moraga homes that already have beautiful outdoor spaces, a well-planned pool renovation brings the pool up to match. Learn more about our renovation services.
You can reach us by phone at (888) 994-7665 or submit a free quote request online. We’ll ask some questions about your pool, schedule an on-site visit if needed, and put together a clear proposal — whether that’s a weekly maintenance plan, a repair, or a full renovation.

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!
