Can I paint the system?
System piping may be painted; however, painting of the fan is not recommended by the manufacturer and may void fan warranty.

Are there guarantees?

We guarantee to reduce the average radon level below 4.0 pCi/L. The manufacturer provides a 5-year warranty on the fan.

When can you start and how long does it take to install?
A typical system takes three to four hours to install with a day or two lead time.

What about testing?

All homes should be tested for radon every 12-24 months.

How do I plan for radon removal in new construction?

If you plan to or are in the process of building a new home, we can install a passive system. The system will be roughed in from the basement slab into the attic and through the roof, utilizing interior partitions which will conceal the piping. Once construction is complete, the house will be tested and, if required, a
radon mitigation fan can be attached to the pipe in the attic to perfect the system.
