Radon Mitigation Services

To learn how Radon Mitigation through G.M.D. Construction can lower the Radon levels in your home, call us for a free in-home estimate.

We will design a radon reduction system as an integral part of your home. The system will be designed so that it does not create additional environmental, health, or safety hazards, or compromise the integrity and comfort of your home environment. Installation, operation, and maintenance cost will be considered and discussed in the design stage.

Sub-slab ventilation, being the most cost effective of the approaches we use, integrates PVC pipes with an exhaust fan. The system creates a lower pressure in the soil both in and around the structure when compared to the indoor pressure, and this prevents the transference of radon and other soil gases to the inside of your home.

In addition, we seal cracks, holes, and other openings to the substructure to reduce the amount of flow necessary for controlling the pressure difference between house and soil. This increases system effectiveness, while also reducing thermal losses and fan requirements.

After completing the installation, a professional independent test lab will re-test your indoor Radon levels. This post-completion test provides proof that we have done our job correctly, and will remove any conflict of interest (from both G.M.D. and the homeowner).

How far away from windows and the eve of the house should the Radon discharge vent be, and why?

Why does G.M.D. Construction discourage tapping the Radon pipe directly into the sump pit?

How do Radon-avoidance measures reduce exposure to other soil gases entering the home, such as sewer or septic gases, mold spores, fungicides, pesticides, lawn and garden care products, termiticides, and methane and garbage decomposition gases?

Can a Radon reduction system really remove the need for dehumidifiers?

Why is it important to have an in-home estimate?

Why is it a good idea to use a professional testing company for a re-test after work is done?

I'm selling my house, and my contract calls for a certified contractor. How do I know your certified?

Why does G.M.D. Construction never use schedule 20 PVC pipe or rectangular downspout in their Radon removal systems?
