What is Radon?
Radon is a naturally ocurring radioactive gas, which can enter homes though cracks, seams, water supply, building materials and other areas. At EPA's recommended radon action level of 4 pCi/L (picocuries per liter), it is estimated that over a lifetime of living in those conditions, 7 out of 1,000 non-smokers could develop lung cancer? For smokers, the number jumps to 62 per 1,000! EPA estimates that nearly 21,000 lung cancer deaths in the United States are attributed to radon-related lung cancer.
Nationally, it is estimated that 1 out of 15 homes has elevated radon levels. That number jumps to nearly 1 out of 3 homes in New Hampshire.

How do I know if radon levels are high in my house or one I wish to purchase?
The only way to determine if radon exists in any home is to test for it. Though test results using test kits available at local stores are acceptable, provided that tests are performed in accordance with EPA standards, SRW recomends professional testing using a continuous radon monitor (CRM). A CRM provides much more information than just the average radon level over the course of the test period, which is what the other testing methods are limited to. SRW personnel hold certification for professional radon testing using continuous radon monitors, and will provide you with accurate, reliable, third party results. SRW follows strict quality control/quality assurance protocols and is fully insured with general liability, pollution and professional errors and omissions insurance.
What can be done about high radon levels?
Fortunately, radon mitigation is rather easy and relatively inexpensive when considering the cost of a home purchase, as low as $1,000 for installation, plus the minimal monthly costs for operation. Of course, these costs can only be determined by knowing radon levels, site conditions, building construction, etc. If elevated radon levels are discovered, SRW can design and install radon mitigation systems to reduce your radon exposure, with as little impact as possible to your home.
Sub-slab radon piping
Sub-membrane system with sump pit
Radon fan and exterior piping
Typical simple installation
It is a little more expensive, but we can run pipes through roof lines for a more attractive look.
Radon system on mounting blocks
Mounting blocks help to make the system look neater.
Interior radon piping
Radon piping (with yellow radon sticker) in the building to reach the desired exit point
Exterior radon fan and piping
Low profile radon fan
Plastic membrane in crawlspace
Radon pipe under stairway
Sub-membrane mitigation piping
Discrete location for radon fan
All openings, like around this sump pit, need to be sealed
Exterior mitigation fan and piping
Open Sump Pit
Open sump pit, before and after sealing.
Another way to seal an existing sump pit. The clear window allows you to inspect the sump pump.
Soil Crawl Space
