"The rep came out and reviewed the areas of concern.  He gave me an estimate on the spot. The next day I decided to go with JBH and the project was scheduled for the following week.  The workers arrived within the scheduled time period and they were very pleasant to work with. They were responsive, efficient and neat. The job was completed in no time.

"We decided to fix our 27 yr old deck by replacing many of the boards, having it power washed, sanded and stained (2 coats). In addition we had them take down the existing lattice work and put up new lattice which they framed out beautifully. Harry's two men (Rob and Rick) were excellent. We are very happy with the quality of their work and would recommend them highly."

Radon Detection and Reduction questions, answered by experts

You'll need to test your home for radon after installing the mitigation system, then again every two years. If radon remains elevated, contact a licensed radon professional, either the contractor who installed the system or a different one, and have them evaluate the system. They may need to make some changes to improve its effectiveness and performance.

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).

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

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.
