Did your home test high for radon? What’s the next step and how much will this cost to remedy? These are common questions and the answer varies greatly depending on several factors. Consider consulting with a licensed, qualified, radon mitigation specialist first to fully understand the radon mitigation process. Upon their assessment of your home, factoring in some of the information below, they’ll be able to provide you with a detailed design and cost proposal. Much of the cost is driven by the criteria below (resource provided by American Society of Home Inspectors website), along with the square footage of the home. Let’s take a look at some of these cost varying factors.
Your foundation/home type will affect the type and cost of the radon reduction system that will be the most effective. Homes are generally categorized according to their foundation design. For example: basement; slab-on-grade, concrete poured at ground level; or crawl space, a shallow unfinished space under the first floor. Some homes have more than one foundation design feature. For instance, it is common to have a basement under part of the home and to have a slab-on-grade or crawl space under the rest of the home. In these situations, a combination of radon reduction techniques may be needed to lower radon levels to below 4 pCi/L. Radon reduction systems can be grouped by home foundation type/design. Visit the EPA consumer guide to learn the specifics of each. This will help prepare you when you meet with your service provider/contractor.
Is there a passive or active system in place currently? What’s the difference?
An active system has four elements:
- an electric vent fan (1)
- a system failure warning device (may also be in the basement) (2)
- a vent pipe running between sub-slab gravel up to above the roof or eave (3)
- sealed and caulked cracks and joints. (4)
If your home has an active system and the radon levels are high, it typically means the system has failed and should be repaired. Keep in mind, the life of the systems fan is approximately 5 years.
A passive system is typically installed at the time the house was constructed and has two elements:
- a vent pipe extending from the sub-slab gravel up to above the roof or eave (3)
- a physical barrier (polyethylene membrane) between the soil and house foundation. (5)
If your home has a passive system, this may help cut the cost of a new system.
