Customers say: Quality work
"Mike, of MCL, made an appointment to review the project and showed up on time. He is very knowledgeable and clearly went over all technicalities needed to take care of our radon gas problem. The next day he sent a quote. The job was finished on time at the quoted price, work was very professional and neat. I would definitely recommend MCL to complete mechanical work of this nature."

"I hired Double Check to do an inspection for a personal decision of "Repair or Replace". Justin came out, performed the inspection, took photographs and answered all my questions. He found some issues like a few shingles missing, popped nailheads and the like. We discussed the Repair or Replace decision. Very knowledgeable and easy to deal with. Highly recommended."

"Mike and his daughter performed the inspections. He was responsive to my questions and doubts and was able to set up the appointment for the next day. I would have expected that the smoke detectors along with the doorbell to be tested - I didn't think of this until after the inspection. I did ask him to check some of the lights (porch, closet) that maybe would have been missed. Price was higher than most but he was able to accommodate my timing."
