Got Radon?

Welcome to Belson Construction, LLC
A professional Radon Mitigator in Maryland!

Sub Slab
Suction System

This is the most popular service that homeowners request from us. With this process, we will remove radon by drilling a hole in the foundation, install piping and add a radon fan which works as a vacuum to draw out the radon gas from beneath the concrete slab.

Sub Membrane
Suction System

A technique used for crawl spaces. We use a micro-microbial plastic sheet that covers the whole crawl space. The sealed plastic works as your slab, trapping the radon gases. A pipe is then inserted into the ground, underneath the plastic and the gases are removed from your home by a fan using vacuum power. 

Activate Builders
Passive System

A passive system is a pipe from your slab often installed by your home's builder. To activate this, you need to remove a section of a pipe and install a radon fan. Afterwards, the foundation cracks are sealed tight.

Radon is a silent killer! It is a Colorless, Tasteless, Odorless, Radioactive gas. Radon is a radioactive gas produced by the breakdown of uranium, found in earth . Radon gas decays and emits alpha and beta particles and gamma rays.   

The alpha particles attach themselves to other airborne particles such as dust, and are inhaled into your lungs. Once inside your lungs, they lodge in the mucus membranes.

The damage from these particles can cause cancer. Your risk of lung cancer from radon is determined by the levels of radon you are exposed to, and the length of time you have been exposed to it. 

The higher the level, the higher the risk.

The EPA has estimated Radon is to cause approximately 21,000 lung cancer deaths each year. In fact, the Surgeon General has warned that radon is the number one leading cause of lung cancer among non-smokers in the United States. Only smoking causes more lung cancer related deaths. If you smoke and your home has high radon levels, your risk of lung cancer is especially high.

    Mike was very knowledgeable about radon. His prices were very reasonable (we had gotten about 3-4 estimates already & they were all much higher). He was able to install the fan on the spot and did great work. I would highly recommend him to anyone who has high radon levels.

    Mike offered to come do a quote at the house within a day of calling him. There was a miscommunication about the time he would arrive, but we were able to figure out a solution and he was able to come later that day. He installed the radon fan a week after the quote was given and was prompt in communicating with me about the completed work.

    Mike was FANTASTIC! Super responsive, very professional, excellent service! We were on a very tight timeline to get a radon system installed before we sold our house. We messaged one night, he came out the next day to give a quote, and he installed the day after that. His work looks great, and his guarantee transfers to our buyer.

    Belson Construction came out the same night to give me an estimate and then was able to schedule the install the same week. We were in a time crunch in selling our home and Belson Construction was able to accomodate. They also promised below level readings for the radon and it came back as they promised.
