For a healthy home for your family! Test for radon in indoor air every year or two. Short-term radon in air test kits or long-term test kits for more reliable results. Radon in water test kits. EPA-approved. Two-way shipping, testing, and official reports by email and mail included in price.
Most basements start leaking water within 10 or 15 years. Efflorescence ("white powder") or musty odors are the telltale signs of an incipient moisture problem. Finishing the basement traps water vapor seeping through the concrete, which causes molds and musty odors in many basements. Rising basement air then spreads molds and radon gas through the house.
Protect your concrete against deterioration before it starts leaking! And definitely, protect your basement remodeling investment by first sealing the walls and floor against water and vapor, molds, and radon.
You are not alone! Basements are the No. 1 complaint of homeowners:
When trying to repair your damp or wet basement, you might get stuck in an endless cycle of waterproofing “fixes” that consume more and more money:
You install a couple of dehumidifiers, costing you $90 a month to run but they pull in more moisture through the concrete and gradually make it more porous. You buy “waterproofing” paint in a store but as a latex-based paint, it is porous and lets in water vapor, and it will soon peel due to efflorescence and water pressure. So, you get a sub-slab interior perimeter drain system (say, $5,000) and while extra drainage is always good, it does little for the inflow of water vapor or for water seepage through the walls. Meanwhile, the increasing concrete porosity will let in more radon gas and you get a fan-based radon mitigation system ($1,200).
Then, you go for a “de-watering system” (internal gutters) which channels water seeping through the walls to a sump pump but this ignores water evaporation and you cannot frame in the walls. So, you select a good contractor to excavate, apply exterior waterproofing coating and repair the footing drains ($14,000). It will likely last for about 10 years but will do little for the slab or dampness. If you finish the basement, water vapor will get trapped behind the walls and under the flooring. Floor tiles will “pop” as alkalis attack the adhesive. High humidity will promote molds, mildew, and musty odors.
Instead of all that, you could have just used RadonSeal.
As the US EPA explains, there is no safe level of this radioactive gas which causes lung cancer, the No. 1 killer among cancers. Radon causes more deaths than fires, drownings, and airplane crashes combined! Among non-smokers, radon is the leading cause of lung cancer, yet the media are bewildered when it kills a non-smoking celebrity.
People assume that the Action Level is equivalent to the safety limits on other carcinogens but the cancer risk from radon at 4 pCi/L is hundred times higher. The mortality risk is three times higher than the risk of dying in a car crash or the equivalent to smoking 10 cigarettes a day (US EPA). Among women, it increases the lung cancer risk by 50%.
The vast majority of radon-induced lung cancers occur in homes with radon concentrations below the 4 pCi/L Action Level. Children are particularly susceptible.
Always reduce your radon level to a practical minimum! The cancer risk is proportional to the radon level. Reducing radon from your current level by 50% (or 90%) lowers the cancer risk to each member of your family by 50% (or 90%). Seal your basement or slab with RadonSeal and then, seal all openings or cracks.
You can order our EPA-approved radon test kits. And if you also purchase RadonSeal at the same time or within two months, the test kit is on us - you will get a $15 rebate.
Mold spores cause allergies, asthma, airways infections, and other health problems, particularly in children. Mold and mildew, fungi, bacteria, and dust mites flourish in high humidity (over 50%). Your basement or foundation slab is by far the single largest source of humidity in the home. The average basement (or slab) lets in over 15 (10) gallons of water each day - several times more than showering and cooking combined!
Use our BioZap Mold & Mildew Cleaner to get rid of visible molds and place several jars of BioZap Air Purifier against all the invisible molds and spores floating in the air or hiding in porous surfaces. Reducing humidity is the key to long-term mold remediation - deep-seal your basement or slab with RadonSeal.
Concrete paints, waterproofing sealers or cementitious coatings are a temporary fix only. They crack or peel and cannot stop gases or water vapor. Why not tackle the root cause of the problem? Seal those pesky pores inside concrete with RadonSeal and combine waterproofing, damp-proofing, mold remediation, and radon mitigation in one!
RadonSeal deep-penetrating reactive concrete sealer penetrates deep into concrete (up to 4 inches!), reacts with lime and alkalis, forcefully expands inside capillaries, and hardens as an insoluble silicate mineral. (Silicates are the "binders" in concrete.)
This is not "your father's" concrete sealant! It does much more than surface sealants and is permanent - you will never have to apply it again! It does not leave a film or color that could peel or wear off. RadonSeal seals porous cementitious materials - indoor and outdoor concrete, concrete blocks, cinder blocks, mortar, stucco, grout, old or new. Backed up by a Limited Lifetime Guarantee !
Quick and easy application with a hand-pump garden sprayer on the inside (or outside) of the basement. (Existing paints or sealers must be removed first!) RadonSeal is a waterborne concrete sealer - zero VOCs, no noxious fumes, non-toxic, nonflammable, and non-hazardous. The surface will remain non-slippery and paintable.
