We just had Samir, Mark, Michael and John out to replace the water heater and install a GFCI outlet, they made sure to take care of us the same way the HVAC team did back in January. They wore booties, drop cloth on our floors, were so quick and efficient with their installation and did a bit of troubleshooting…

I just got an estimate for a new water heater and the estimate was for substantially less than what I was quoted from another company. My neighbor had to get a new water heater a couple of years ago and recommended CM. I’m glad took his advice!
