"Professional, punctual, knowledgeable, and honest. After I contacted him to hire him for testing he came by and offered to test, then explained how the radon level was low during warm weather. However I still wanted to test. When the test came back very low level, he offered to come back, and retest for free during the cold weather. I would definitely recommend this company to anyone needing Radon testing or mitigation."

"Brian was really friendly and professional, and you could tell he was very thorough. He explained everything in a way that was easy to understand during the inspection, and the report he sent after was super detailed with pictures and notes on all the systems in the home. I especially liked that he included a section that called out the main issues to focus on. Overall, we were very happy with his service and would definitely recommend him to anyone."

"Crew was great, including electrician. In hindsight, I wish we had installed the apparatus differently. We did it (which was probably easiest for the installers), outside through my siding. Looks like the Tech Trail BC lead plant with the huge tubes bulging out of the back of the house, near the deck (i.e. noise). I still have not tested to determine the efficacy of the radon abatement. I will need to contemplate this purchase some......"

"My wife is very sensitive to mold and we already had a mold issue with our existing house that was remediated. So when we made an offer to buy a home, we needed to make sure we knew if there was any mold related issues. James performed a through inspection for mold of the house. He inspected the craw space, attic, interior, and exterior for all possible sources that could produce mold and took 5 air samples for lab analysis. He found some problems requiring fixes such as mold damage in the attic, excess water running into the crawlspace, inadequate insulation, missing insulation, cut wires to the fresh air intake, ductwork that was never installed, and a fallen vent stack in the attic. We will use him again the next time we do a home inspection for mold."

"This company was professional from start to finish! Setting up the appointment was quick and easy, they showed up on time and were concerned with my needs. They wanted to make sure the system was going in the proper spot, both inside and outside, and wore a mask and booties the whole time. I was impressed and will hire them again!"

Radon Detection and Reduction questions, answered by experts

You can vent radon out of your house sometimes by simply opening a window, but it won’t remove the source, and will likely rise above recommended levels quickly. A professional will be needed to assess your home, and determine the best strategy for radon removal. Active radon sump pumps and soil depressurization systems are often used to forcefully vent the radon from your home.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

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

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

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.
