Annual maintenance of our heating system. Arrived on time and was very professional.
Brett came to do an annual service on my burner and pointed out to me that there was a problem with the (gas) hot water heater which wasn’t wholly upright. If he hadn’t taken the time or hadn’t cared, I could have had a disaster. I have always loved Densmore — they are the best!
From the initial quote to the final inspection of the the completed project, everything was well- managed.
