"Corey and David of John's Waterproofing Company took our project and had a commercial grade gas water heater installed and running in place of our old one the same day they received our call for service. Thank you John's Waterproofing."

"Very impressed with Darren: his work ethic, thoroughness of the work, cleanliness of the job site when the job was finished. He arrived when he said he would and stopped by when he was done for the day to let me know he was leaving. I certainly would recommend Pacific Waterproofing, LLC."

"The problem ended up being plumbing and not waterproofing. But TerraFirma did a consult right away, diagnosed the issue quickly and was really helpful in figuring out the next steps. I really appreciate their time."

"Our shower was leaking into the basement. Azzi was able to come out the same day to diagnose the problem and schedule service. He was professional, friendly, tidy, and completed the substantial work in one day. He explained everything in terms we could understand. His work was excellent! We feel that we received quality and long-lasting solutions to our plumbing problems. We can't recommend D & F Plumbing enough. Ask for Azzi!"

"I appreciated how methodical Jon-Marc was in diagnosing the problem behind the leak in the kitchen ceiling from the upstairs bathtub, which appeared at first to be a failed shower diverter. But, when, after removing the faucet, the physical evidence inside the wall did not match what he expected to see with that issue, he kept looking and testing. Eventually, he identified the real problem as a failed seal around the wall soap dish, which plumbers don't repair. However, he also established that there is nothing wrong with the bathtub plumbing, which is good to know. He installed a new diverter, as the old one was starting to fail. Jon-Marc was courteous, professional, knowledgeable, and good at his job. He answered all my questions, explained what he would be doing, and stayed until the job was finished. He also kindly found that the leaking garbage disposal had rusted out. This was the second time I hired 3 Mountains Plumbing. I highly recommend the company and would hire them again."

"They responded quickly and efficiently. They were able address the issues and dry out the area quickly. They are very supportive during the entire stressful situation."

"Martin and his crew tore up a paver patio and partial lawn and installed a beautiful patio with pavers and river rock. On time and worked quickly! I was really happy with how I was treated and the quality of work they did. It was a small project which I sometimes have a hard time finding people for and Martin was eager and made me feel like it was worth his time."
