Outstanding. The project manager was excellent. He kept the crew on task masking and painting. They took care of my property and made sure everything was taken care of and protected. The end result wasn’t just a house painting, it’s a work of art.

Wonderful Philip Knopp. He removed the old roofing, and replaced it with a 30 year life. He was very neat and clean. He did everything himself and I am being asked how can one man do the big job, and have it done in 1 week. My daughters house is on the list for next year. Thank You Philip

Radon Detection and Reduction questions, answered by experts

Installation typically takes 1-2 days, depending on the system and property layout.

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.

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).

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