Basement & Radon Solutions, BRS Pros, did quite a bit of work for Yana and this is how it went:1. We removed all the contaminated sub-floor insulation from the crawl space.2. We then fogged an EPA registered fungicide, cleaner, and deodorizer into the crawl space. (This will kill 99.9% of mold spores and will inhibit the growth of mold and mildew!)3. Now that the crawlspace was cleaned we installed new R-19 Kraft faced batt fiberglass insulation to the sub-floor of the crawl space. 4. We then proceeded to seal all of the foundation vents with 2 rigid foil faced insulation from the interior. (This will prevent any exterior air and moisture from entering the crawl space!) 5. The crawl space was then made RADON READY. We installed 4″ suction pipe that would lie bellow the liner. This in the event that the home has a high radon gas level reading in the future, this component will be used with an addition on an exterior radon fan. It is much faster and cheaper to have this in place now than down the line if there is an issue!6. We then installed 9 mil white 100% woven reinforced liner to the ground and over the RADON READY piping. This 9 mil vapor barrier will control the moisture vapor and dampness from the ground. This made in the USA liner is guaranteed not to off-gas! 7. Lastly, we installed an Aprilaire 1850 dehumidifier in the crawl space. This model will remove up to 95 pints of moisture per day! It is also made in the USA and comes with a 5 year manufacturers warranty. It was a pleasure helping Yana get her new home safe, happy, and healthy!”
