"My pool was such a gross mess. Trying to maintain a farm for the first time and never owning a pool before either, it was such an overwhelming task for me to learn how to keep a pool. It didnâ t help every year that something would break and past pool people would take advantage of the fact that I didnâ t have any knowledge about pools and overcharge me for fixing them or replacing parts that I didnâ t need or couldnâ t use. It was just one thing after another in order for me to get this pool running, so I ended up trying to dig my head in the sand about it. I hoped to get it filled with dirt or leave it empty, but Hugo informed me of the problematic issues of doing those things. Before Castle Pools, no one else would touch it. As soon as I mentioned it was green, every pool company would back pedal and tell me they were too busy. I didnâ t realize there was a certain time of the year youâ re supposed to have your pools done and apparently calling in May was too late in the season. But Hugo and Brenda were the only pool company who were willing to help me. Never once did they make me feel like I was a terrible pool owner or like I had done something wrong or out of the ordinary. They basically told me donâ t worry, we got this, so you wonâ t have to! What a relief and I felt like a ton of bricks had been lifted off my to do list. They have a full clientele and I didnâ t realize this, but they still made it a point to come after their normal business hours to check on the progress as we were emptying out the pool and refilling it. It went from being a pond housing a village of thousands of frogs and salamanders to being a crystal clear, working pool again. It took two and a half days of pumping it out and another day of pressure washing and pumping, and 4 days of filling with water, but it actually is a luxury I will get to use now! I have lived here for over four years and Iâ ve never once been able to use my pool! Aside from the great care they have given our pool, Hugo and Brenda are also just genuinely good people. They have a great energy about them, are friendly, reassuring, and reliable. They communicate well and always came when they said they would. A big huge thumbs up for them! Thank you Castle Pools and Spa! Thank you Hugo and Brenda!"

"The service went well. They were able to clean the parts of the home I needed cleaned within the 4 hour time frame. Two people came out for the service and brought their own cleaning supplies. The vacuum they did use did not clean the rugs very well. They did have to come out quite a way to get to me so I would not hire them again because of how much the travel fee would be. They did fine work and I had no problem scheduling the service."

"They were absolutely fabulous and the most knowledgeable stone contractor I dealt with and there were 5 all together! They were completely professional and even when things took longer than they anticipated they did not charge me any more. I LOVE this company and will never use anyone else again! We had problems with 4 other stone contractors before they came in. They fixed all of my problems and were absolutely charming to deal with. They turned me on to some amazing cleaning products as well. I thought I had to replace our master shower enclosure and they gave me a stone cleaner that took ALL the hard water stains off of the shower door in a matter of minutes - I sprayed it on rubbed it in with no pressure at all waited 15 minutes and rinsed it off and it looked like a brand new shower. I had a cleaning business for 15 years and I never saw a product like it; it also cleans the stone in the shower of course. The owner Todd is incredibly knowledgeable and he can help you with any stone problem you have I am sure of it. They also gave me a 6 year warranty on all of the surfaces they sealed!"

"I hired Jacob and his crew to renovate my old bathroom in Oakland. They worked fast to get the permits and had his designer to assist me with choosing the tiles and Vanity. The finished result was clean and elegant. Highly recommend these guys to anyone in the area!"

"I paid for the recovery of the Freon, everything else was covered under the warranty. I know what it would have cost if it wasn't covered. I would tell anybody if you have an house, you need to have them. They have been very good to deal with. They were very polite, and very professional. It took about three hours to complete. It was completely cleaned."
