"Very personable, small family business. We loved working with this father-son duo. They were transparent about cost, were timely, effective communicators and were really flexible with us when we ended up installing at least twice as many lights as we were planning on. They also walked us through all of the work they were doing and taught us tips and tricks along the way. I highly recommend Rick and Aaron."

When he realized neither of us had the size mount needed to properly support the big TV, he went out and got what was required. He was professional, polite and got the job done for a reasonable rate."

Paul The Plumber is here to help you with all of your plumbing, heating, and air conditioning needs! From repairs to replacements to proactive maintenance, we'll always provide honest, expert recommendations and personalized solutions. Our goal is to ensure your safety and comfort no matter the season. Every contractor on our team is trained, experienced, and puts quality customer service at a priority.

"There is not a category for this project.. a shower head cartridge replacement. The cost on the flat rate for Paul the Plumber $969. This flat rate price is way above anyone else who would perform this job. There were no complications involved but the cartridge had to be picked up from another truck. I have learned from other plumbers with a good reputation that the cost should be around $400 without complications which mine was. "
