Before

The home had elevated radon levels in both air (7.1 pCi/L) and water, with no mitigation system in place. The stone foundation and open slab areas required sealing and preparation before installation.

After

A two-pipe radon mitigation system was installed, with coverage across both the main foundation and slab. The system includes a sealed cemented section, a protected exterior pipe with a critter guard, and rough-in piping for a future bubbler system.

Explore the transformative effects of our radon mitigation system overhaul in a Shelton home. Initially equipped with an underperforming system, our intervention included removing redundant pipes, installing a new high-capacity fan, and refining the system's ductwork to enhance air exchange. The after photos display a streamlined and more effective setup, demonstrating our commitment to delivering superior air quality and safety within the home.

Before, The home, built in 1908 with a tall profile and a fieldstone foundation, presented a few unique installation challenges. With no sump pump, no water guard, and no encapsulation, the system required thoughtful planning. The client, who is moving but will rent the house out, arranged for the back door (not the bilco) to be left unlocked. The installation area was behind the washer, a bit to the right when facing it — on the opposite side of the wall.

After, A two-pipe radon mitigation system was installed to address the radon level of 13 pCi/L. Due to the tall structure, additional vertical piping was needed to route to the roofline safely and discreetly. The pipes were strategically placed to maintain structural integrity and avoid interference with the washer area. The final system blended into the home’s design while effectively venting radon gases above the roofline, ensuring long-term mitigation for incoming tenants.

See the transformation in radon safety through our before and after visuals of a colonial home in Watertown, CT. Starting with a radon level of 4.1, we installed a mitigation system strategically on the back corner near the sunroom to maximize efficiency and discretion. The after photos illustrate the unobtrusive installation and significant improvement in radon levels, ensuring a healthier living environment for the homeowners.

Before: Incomplete passive system with high radon levels (9.0 pCi/L).
After: Full active radon mitigation system utilizing the existing passive pipe start, routing piping through the Bilco door drywall to connect at the furnace, and installing the fan outside—strategically placed near the water spout while maintaining distance from nearby windows.
