Lots of trash in this dirty crawlspace
All of the garbage in this crawlspace creates a likely breeding ground for mold, wood rot, critters and bugs.
Air ducts laying in the wet dirt and puddles
Many homes have soft air ducts like this one. They are covered in fiberglass insulation, which contains organic material. This material can grow mold very easily. So when those ducts lay in wet dirt and puddles of water, they grow mold in the crawlspace much quicker. A proper vaper barrier and moisture control system like the CleanSpace system can prevent this from being a problem.
Stringy insulation and messed up plastic
The stringy insulation is due to high humidity and moisture in the crawlspace. The plastic is what they typically use when building a home. It doesn't last long and has holes and gaps so it isn't even a real vapor barrier either.
Filthy crawlspace
Its just so dirty and wet in this crawlspace. Unfortunately most houses around the shore are like this. It could be a house in Fenwick Island, Cambridge, Salisbury, St. Michaels, or Oxford and no one could tell the difference.
SaniDry CX dehumidifier and CleanSpace vapor barrier
The SaniDry is a great crawlspace and basement dehumidifier/air machine. It will pull up to 109 pints of water out of the air per day. This dries the air, wood, and building materials in your crawlspace, basement, and even the rest of your home. The CleanSpace Vapor Barrier is a thick 7 layer liner. It is overlapped and doubled taped with strong seamed. It is very hard to tear a hole in it and will give any home the best protection against wood rot, mold, mildew, and odors.
Reflective white plastic
One of the fringe benefits of the CleanSpace liner is that it reflects light really well. It makes the crawlspace look amazingly clean and easy to navigate.
