Discover How a Crawl Space Dehumidifier Can Protect your Home From Wood Rot

Humidity and moisture in your crawl space can often lead to a serious problem for homeowners not using a crawl space dehumidifier; wood rot. Wood rot, also called wood decay, is caused by microscopic organisms that belong to the fungi group. These organisms are what cause the wood to actually decay.

Wood is comprised of 3 major components: cellulose, hemicellulose and lignin. Wood rots because the fungi “eat” these 3 major components of wood cells by releasing enzymes that digest wood cells.

Wood that has a moisture content of 20% or above is very susceptible to rotting. The attacking fungi require 4 conditions for colonization:

1) Adequate oxygen supply

2) Temperature range between 40-100 degrees Fahrenheit

3) Constant moisture source

4) Adequate supply of food (wood)

Untreated moisture damage can cause a decrease in your property value by 10% to 15% according to the National Association of Waterproofing and Structural Repair Contractors (NAWSRC).

Catching moisture problems like wood rot in the early stages will save you both money and headaches. There are several warning signs to alert you that moisture may be damaging your home: excessive condensation on windows, blistering or peeling paint, discolored wood surfaces, splits across the wood grain, mold spots, musty odors and standing water in your crawl space.

If you notice any of these warning signs, you need to determine where the moisture is coming from. Check for plumbing leaks, roof leaks, debris filled gutter and downspouts, foundation cracks and poorly graded soil that drains towards your home. In your crawlspace, look for mold stains on the foundation walls and/or puddled water.

Moist, humid air from your crawlspace increases the moisture content of the wood in your home, making it vulnerable to wood rot. By installing a vapor barrier and a high grade crawl space dehumidifier, you can protect the value of your home.

On a Tuesday morning I found a stain on a bedroom ceiling, indicating there was a leak in my roof somewhere. The weather forecast for Wed said torrential rains were coming so I went to the first contractor I found. The worker walked around on the side of the roof where the leak was found, hammered a few nails, sealed down some shingles, caulked a few areas and left with $450 of my money. Did I get ripped off, or because it was short notice and in light of the impending bad weather, was this cost justified in any way? (The contractor told me to mix equal parts water and bleach in a spray bottle, spray this on the ceiling stain and when the stained section matches the rest of the ceiling, to stop. At that point, I'm to keep an eye on that spot to be sure the stain doesn't reappear.) So, what do you think – I'm a widow and don't have all the knowledge I should, but I sure hate to get "taken". At this point, it'll just be a lesson learned, but at least I'll know better next time!

    i would think if you had damage to your roof that would be covered by insurance you would have already contacted your insurance company. the contractor can look at the roof, assess the damage and give an estimate. filing a claim is your responsibiity (if it's your house). in most cases, repairs from general wear and tear are not covered by homeowners insurance. contact your insurance company yourself to find out if the repairs will be covered before committing to anything with a contractor.

    Since you are a Yahoo user, why not try the Yahoo Yellow Pages:

    Check out any prospective contractors references and ask for a certificate of insurance proving that they carry liability and workers compensation insurance. Do not give your contractor a large downpayment … no more than 10%, with the balance due upon completion.

    Good luck with your search.

    Contact the "Contractor's State License Board". The board will investigate a complaint such as this. Obviously, the work wasn't done properly or there would be no leak ! The contract should be for a "scope of work". That would make the contractor liable. He cannot deny responsibility if the roofer was paid by him.

    The drip edge should match the fascia and soffit. It's available in all of the colors that the F&S come in, so there's no excuse for not using it. White drip edge with brown fascia looks terrible, as you can see. Hope this helps.

    I think brother deserves a huge hug and a thank you from sis! He was taking care of his sister because most of these guys will not do that! Oh, there might be a couple but I sure as heck haven't found them.

    Go ahead…it started what? leaking again. You could go up into the attic (loft) and look for the dripping while a friend uses a hose on the roof. Because it was roofed doesn't mean it was roofed right.
    Call the contractor back and let him know right away.

    There is ALWAYS someone who is willing to do the work and will do a good job. Typically this person does not advertise and works on referral. Continue to ask your neighbors and friends and local supply stores (not Home Depot) and you will come up with someone.

    The insurance you speak of is typical and all licensed guys can provide this.

    Most typically, it's a sprayed polyurethane foam system. Simple repairs can be made with a sealant, unless you need a section replaced.
