"Everyone I spoke to at Cotti-Johnson from the estimate through to installation of my generator were polite, professional and a pleasure to deal with. At the outset, the scope of the project and its cost was explained to me in simple and understandable language. The installation took place precisely on schedule and was completed within 3 hours. I received the necessary follow-up calls from the office to ensure the work was done to my satisfaction. I couldn't be happier with Cotti-Johnson."

"I could not recommend Mike enough. He cleaned our oil furnace, conducted CO safety tests, diagnosed an issue with one of our old radiators, and installed a smart thermostat, all for a fair price. He's friendly, diligent, prompt, communicative, and careful. We also appreciated the extremely detailed documentation he put together at the end of the project to cover the costs and work done. While we had quite a bit of unexpected work (which comes with living in an older house), Mike was transparent about what was urgent versus what could wait for later projects. It never felt like he was upselling us. Will continue to use Mike for any of our home heating needs."

"Very well. They are honest. We had a leaking roof back in 2014. Most of the roofing companies said we need the new roof then we called Lightfoot company and they came out to patch it up and it still lasts us until 2021."
