Before: Radon levels at 14.0 pCi/L, unsealed cracks, and a crawl space contributing to air quality concerns.

After: Three extraction points installed, every visible crack professionally sealed, and full coordination with CT Basement Systems for WaterGuard sealing. A collaborative, comprehensive fix for radon safety.

Originally built with just one extraction point, this Burlington home needed an upgrade to better handle basement airflow and radon dispersion. After installing a second extraction point and optimizing interior pipe runs, radon levels are now better managed. Our before-and-after visuals capture this critical improvement, showing both added functionality and clean installation.

Prior to installation, the home was unoccupied and radon tested at 2.3 pCi/L—just slightly above the client’s personal target threshold of 2.0. The homeowner had recently purchased the property and made it clear that he would not move his pet in until the radon concern was addressed. There were no sump pumps, water guards, or crawl spaces, and the foundation was solid cement—making for a clean canvas for the system.

 

After installation, the radon mitigation system was professionally installed with a direct run that minimizes any airflow restriction. While not a high-level reading by EPA standards, the system was designed to achieve optimal sub-slab depressurization to bring the level well below 2.0. The "after" look showcases a polished setup, with no disruption to the structure and a clean, code-compliant exterior fan setup.

Before: The small Cape-style home, constructed in 1958 in West Haven, showed radon levels at 4.8 pCi/L, just above the EPA's action level, in an environment with no existing mitigation infrastructure like cracks or sump pumps.

 

After: Following the installation of a streamlined one-pipe radon mitigation system, radon levels in the home have been successfully reduced to safe levels. The system's discreet placement on the right side of the house minimizes visual impact while maintaining effective radon evacuation, securing a healthier living space for the occupants.

Explore the significant transformation in radon levels through our before and after visuals of a radon mitigation project in a Hamden split ranch. Starting with a radon level of 5.6, our intervention involved installing a new pipe system alongside household utilities. The after photos highlight the professional installation next to the washer and dryer, discreetly extending to the shed side, enhancing both safety and aesthetics of the home.
