Couldn't have been better

Thompson was recommended by a friend who had used them. I am so glad she suggested them. The service, professionalism, timeliness and products are all top-notch as were the techs on the jobsite. We highly recommend them. Their pricing was WONDERFUL when we compared it to their competitors!

Awesome Experience

No one loves to spend money on AC issues. Dylan made the process as painless as possible. Was great with my kitty also. Nice to hear he is a Marine vet. Happy to be a new member of the Thompson family. Will recommend to friends and co-workers in our local area. Very thankful him and Trevor were able to tag team the ducting work we were also getting done. There was no need for double work. I appreciate the thought that was put into everything as he saved us time and money by preventing redundancy.

I feel lucky to have found Thompson Plumbing. From scheduling an appointment with Ellie to Delfino coming out to diagnose the problem. There was great communication throughout from Ellie. I found Delfino respectful, courteous and very easy to deal with.

For this job, we were called out because the homeowner noticed his ceiling in the living room was bubbling. When I arrived I noticed the bubbling above the area where the television is located. I cut the drywall open and immediately saw water dripping down from the ceiling. The leak was caused by a pipe burst on the home’s copper pipes. The leak was on a one inch tee fitting . I removed the damaged fitting and installed a new tee as well as new sections of copper. Once I finished I turned on the water to the home and checked for leaks . No leaks were found.
