Radon Mitigation for Garage Floors in Katy TX

Is the Garage a Radon Risk?

Attached garages can be a radon entry point if the garage slab is unsealed and the home has air pathways between the garage and living space (door gaps, ductwork, wall penetrations). In most Katy TX homes, the attached garage is a moderate radon risk — more so than a detached structure. Sealing the garage slab reduces the radon load entering the garage, which in turn reduces what migrates into the home.

Sealing Protocol for Radon Reduction

For radon-motivated garage floor sealing, we use a high-build epoxy system with emphasis on: crack injection at all visible cracks and control joints, penetrating primer to close the concrete's micropores, and 2–3 coat epoxy system with minimum 30-mil total film build. This creates an impermeable layer across the entire slab surface — the same barrier that stops moisture from entering also stops soil gas.

Coordination with Certified Mitigators

For homes with confirmed radon above 4 pCi/L, we recommend working with a certified radon mitigator before or alongside floor coating. In some cases, the mitigator installs sub-slab depressurization pipes — and the epoxy floor sealing is done after the pipes are set. We coordinate this sequence regularly and can connect you with certified mitigators serving the Katy area.

Documentation for Real Estate

If you're sealing a garage floor for radon reduction in a home you plan to sell, document everything: pre-test result, installation date and products, post-test result. Texas sellers are required to disclose known radon issues, and documented remediation steps protect you and provide value to the buyer. We provide a written record of all materials and methods for your file.
