Get matched with top attic or whole house fan installers in Mendon, MA

"Daniel and team was very professional, knowledgeable and personable. I had a smart switch issue with multiple poles and they were able to solve the problem and make the right connections. Additionally, they identified a faulty breaker and replaced easily. Any other services they recommended as part of the whole house safety assessment, they did not push for anything and was very clear on the optionality and overall value if I wanted to pursue. I ended up electing a whole house surge protector as it was something I was considering and their service made it an easy decision to move forward with it. Overall, I had done a great deal of research and very glad I went with Cotti-Johnson."

We had a Bath fan install + an exterior electrical outlet installed and he was able to get it done within a few hours. The install looks clean and he took care to clean up afterwards too. Great work Scott! Thank you!"
