It is extremely common for homeowners to have issues with their crawlspaces. While some homeowners take the DIY route, these attempts might only exacerbate the issue at hand. Below are four common DIY mistakes for fixing a crawlspace issue under your home.

1) Using Fiberglass Insulation

It is commonly mistaken that jamming extra fiberglass insulation between the exposed joists in the crawlspace will help insulate it; however, the insulation tends to absorb moisture and support mold.

2) Using Vapor Barrier on Floor Joists

It is another common mistake for homeowners to staple a vapor barrier to floor joists; however, this can trap moisture and lead to mold growth and wood rot.

3) Using Gutters and Downspouts 

Although gutters and downspouts are used to capture and funnel water away from your home, sometimes water isn’t carried far away enough and can cause water to pool around your foundation walls and seep into your crawlspace leading to mold growth and wood rot.

4) Appliances Being Vented into Crawlspaces 

Homeowners are sometimes under the impression that the current ventilation in their crawlspace provides enough air movement to counteract the damp air created from a dryer vent; however, this can quickly cause mold growth and wood rot.
