Standing water in a leaky basement?

Insist upon the non-clogging WaterGuard® interior drainage system and a wet basement is a thing of the past. Don’t rely on old, easily clogged french drains using outdated waterproofing knowledge – make sure you get the best patented basement repair technology on the market today.

Want your basement dry all the time?

Check out our TripleSafe Sump Pump System – the best basement sump pump available to keep your basement dry year round. Never worry again about water backing up from a frozen or clogged discharge line with our IceGuard® System.

Damp and musty odor?

Eliminate the leading cause of basement odors – high humidity and other indoor air allergens – with the SaniDry™ Basement Dehumidifier and Air Filtration System. Our approach controls the relative humidity of your basement to prevent mold from growing. This means that you and your family won’t need to worry about mold spores circulating throughout your home and can enjoy fewer odors and healthier air.

Preparing your basement walls for finishing?

Restrict moisture and water vapors from entering your basement and add a layer of basement sealer to protect from mold at the same time with our CleanSpace® Basement Wall Vapor Barrier.

Leaking window wells?

Eliminate flooding from inefficient or poorly designed egress window wells with the WellDuct® Window Well Drain. Our crews are trained for careful, attentive work and will cause minimum disruption to your home while completing the installation.
