"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."

We feel that we have one of the best quality controlled companies in the area. We DO NOT subcontract work out, all of our work is done by employees of Roof Doctor. This ensures a consistent product that protects your home.

"If you are in need of a Doctor you have come to the right place. We where out of town and a tree which was over a hundred feet tall fell on our house. I called the roof doctor and Jay had a crew out there the same day to remove the tree and tarp the roof. His quick action saved us from further damage as another storm came in the next day. Jay's crew at roof doctor repaired all the damage and installed a brand new roof. At a reasonable price I might add. Thank You Roof"

Radon Detection and Reduction questions, answered by experts

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

Costs for radon detection services typically range from $150 to $250, depending on the testing method and whether a professional assessment is required.

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

Use a radon test kit or hire professionals to conduct a detailed assessment of radon levels in your home.

Avoid opening windows and keep doors closed during testing to obtain accurate readings.
