"The inspection was incredibly thorough with an excellent report provided. We learned a lot about the house and Matt was incredibly knowledgeable. We are buying this house built in 1893 with the confidence to know all positives and any problems we may run into. Septic system was inspected extremely well. We were also provided a visual look at Seawall and dock including a test of the boat hoist."

"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."
