Dave responds very quickly and takes his time diagnose the problem to fix it at the root. We had a ceiling light fixture that was filled with water and couldn’t locate the leak. Dave opened up the ceiling minimally instead of tearing everything apart and worked with us to find out the history of leaks. We avoided a lot of unnecessary work and completed the job in time.

Dave responded very quickly to the inquiry made and even told us how we could resolve the problem on our own. In the end, we didn’t need more service than necessary.

My bathroom light switch died, and I was able to secure an appointment and quote almost instantly, and the morning of, he showed up exactly on time and had it fixed in 15 minutes - will definitely call again for any electrical needs! Highly recommended!

Dave did an amazing job upgrading our Google Nest to the latest version. He did an awesome job installing, mounting, making sure we had the secondary sensor mounted and testing heating and AC when everything was done to make sure we were good to go. Great work and highly recommend!

He came down to check the issue free of cost which was great since we had already spent paying other people to fix our electrical issue who could not fix it. He is really skilled in understanding the root cause of the issue and took the time to completely fix it. He took care of the safety issues as well and made sure the job is fully done. We also got our sink and some plumbing work done by him and he was successful in fixing those as well. Really appreciate the work and will definitely reach out again if any issues come up.
