"Mark was able to replace my water heater quickly and efficiently and went the extra mile to make sure I understood the function of the heater and the water leak gauge -- my old one was improperly installed and submerged by water (super helpful. not.) On a follow-up call he even turned me on to a trusted electrician, cuz I need a bathroom ceiling fan installed. Two thumbs up!!"

"We called at 8 am and had a technician here by noon. A new water heater was installed by 2:30. Milton was compassionate (we were frazzled) and knew exactly what to do. Really grateful for the care and expertise."
