"Lesson learned. Always get an estimate. BEFORE the work is done. At least a digital copy. Arrangements for the project were made, with some one named Lynn, for the company to send someone to complete the work. We were quoted over the phone 4500-5000 which included a mold test. A sub contractor with an entirely different company (National Mold Company) was sent. When the contractor arrived, he stated that the job would be much more simpler than first thought. This led us to believe that the job would cost less, no. All said and done, they charged $5500. All said and done, it's almost like no work was done. The stains and the smell are still there. Only one actual board was taken upon the attic room. The ceiling in the bedroom was primed and painted but are still visible and have a funky smell. At this point I'm going to. Do what we should have done; Do the job ourselves. Just now with $5500 less dollars in our pockets. A detailed receipt was not given even though it was requested."

"My house had excessive levels of radon in our lower level. The Lance Dorfi team installed a pump to pump out the radon and release it up above the roof of the house. Since then, radon levels in that part of the house have been very low, so the problem was resolved. The work was done on budget, and they did an excellent job with scheduling and customer service.

"The inspection was a farce. We received a list of very minor repairs that needed to be done along with a couple of recommendations for system replacement due to age in the future. The inspector did not go up on the roof. If he had, he would have seen how soft the roof was. My wife notice the porch roof leaking during our remodeling project as the insulation was wet. Our contractor walked the entire roof and said it was an emergency to replace it. Sure enough 1500 sq feet of plywood of a 2000 sq foot roof had to be replaced. It was soft, splintering and wet. The splintering and disintegration should have also been visible from the attic hatchway. I am out $12,500 because of his negligence or laziness, I am not sure which. Do NOT use this company under any circumstances."
