"Radon gas in my house’s lower level was 3.6 picocuries per liter: below 4.0 pCi/L, at which EPA urges remediation, but high enough that it’s recommended. Beginning a week after SWAT installed gas elimination system (for $850), radon level dropped to 0.3 pCi/L: about the same amount of radon as is found in fresh air. Nuff said."

"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."
