Why Do I Have Wood Rot?

Wood rot is caused by a fungus, which is attracted to damp spaces like your crawl space. If you have crawl space moisture then it's most likely the source of your floor joist wood rot.

When you vent your crawl space, or if there's a crack in your crawl space foundation, it creates crawl space humidity which is the biggest source of crawl space problems. Crawl space moisture, or humidity, is created when the warm outside air mixes with the cooler air in your crawl space.

Crawl space moisture doesn't just cause wood rot; it's the source of many home problems:


Mold loves your damp crawl space. And if you have a moldy crawl space, chances are it's being cycled through the rest of your home, where it grows on floor boards or furniture, and you end up breathing it.

Dust MitesDust mites:

Crawl space moisture is a dust mite's best friend. These allergens can only live in high humidity spaces, and are the primary source of many allergy and asthma problems. If you have wood rot then you have crawl space humidity, which then cycles through your home and invites dust mites in for a visit.

Wet Crawl Space InsulationWet crawl space insulation:

Wet crawl space insulation is not only a mess to clean up and replace, but it's also a breeding ground for mold and mildew. Not to mention the wet insulation also looses it's R-value, which decreases it's ability to insulate your crawl space.

"I was extremely happy with all those on the work crew for the work they performed and their professionalism. They worked continuously until dark, sometimes working until after 7:30 pm. Their finished product is impressive and they left my wife and I so glad that we selected your company. Best of all, my wife who is highly allergic to mold and mildew, has been able to breathe better than she has since we bought the house, so this is great!"
