Why LumberKote? Why do I need it?

     LumberKote™ is the best solution to ensuring the perfect crawl space encapsulation or can be used alone and delivers an unmatched level of protection and peace-of-mind in re-active damage repair, pro-active damage prevention, stage or budgetary situations.  

     HUMIDITY will ALWAYS be the number one adversary for us here in South Carolina. How do you fight hot, damp air? To answer that question let's briefly look at why we have crawlspaces. Crawlspaces were designed to elevate the home off the ground and provide easy access to electrical and plumbing lines. Crawlspace Ventilation was added to allow air to flow under the house to dry out the dark space. 

     However, down here with our humid climate, and semi-tropical rain fall is where things tend to get a little tricky. Wet air evaporates but then re-condensates onto the organic material under the home that make up the structure ie. floor joists, sub floor system, girders...etc repeatedly, over and over again. It's the worst teleportation trick in the world, along with this analogy. None the less, Overtime, we begin to see signs of this "trick" in the form of efflorescence (a white residue left behind on the block when water evaporates leaving behind a calcium residue.) eventually mold spores begin to grow (at 60% humidity levels and above), deterioration of the crawlspace framing occurs, Various types of moisture damage as well as odors in the home are the results of a problem that's gone unnoticed and unfixed for a long time. 

     LumberKotes polymer sealer is an ACTIVE micro-film that fully protects your investment from mold, mildew and wood rot. Lumberkote is hands down the smartest product out there and will save you THOUSANDS.  LumberKote will be protecting the most vulnerable part of your home around the clock, non-stop and without fail. Providing you with the highest quality peace of mind at a reasonable and affordable price. 


How much is it and what about a Warranty?
