"Zach Brown initially came to fix leaking water situation and then realized there was damage due to water seepage. After that damage is repaired, Zach will return to put plumbing back in order, including replacing faucets which had to be cut out to allow removal of granite countertop, reconnect water lines and possibly reinstall a new Reverse Osmosis system since the old one had to be removed. Can't say enough about Zach -- his professionalism, his explanation of what's being done and options for replacing/improving plumbing under kitchen sink, pipes, etc."

"I had an incredible experience. My water heater was leaking and ready to let go. Brian had contacted me. He set up an appointment the next morning. The two gentleman ( plumbers ) came in. Removed the old water heater. Installed the New water heater. And updated the vent piping because it was old and out of code. They did a wonderful job. And I cannot speak highly enough of them , the speedy work and their professionalism. I now have a new plumber for all my plumbing needs. Thank you."

"Angel was exceptional, professional, efficient, clean and responsive to every request, fixed numerous issues related to my toilets, noticed a flooring issue that we are now addressing and diagnosed a water heater issue that had been attributed falsely to a foundation issue saving us thousands. They are expensive compared to many but worth every penny we spent."

"This is my 3rd service call completed by Peterson Plumbing.  The bearings on my disposer were going, making a nasty noise.

I bought a replacement unit and had Paterson replace it.  the job was done properly and promptly and for a price that makes doing it yourself a thing of the past.  He cleaned up and left the place the way he found it.

Thus another job by Peterson was completed."

"

I called Kris U. in a panic because an unethical contractor had totally messed up our very expensive HVAC system, and the condensers had been sitting unconnected for 18 months! Called Sila, they had no idea what to do. Called Kris and he sent in Gregg H. to reconnect everything, drain the condensers and recharge them again. He did a great job and it turned out we did not have to buy new condensers -- hooray!

I highly recommend this company, since no one else was willing or had the inclination to tackle this.
