Installing a crawlspace vapor barrier

Crawlspaces tend to become the home of many creatures, from mice, rats, skunks, to mold and mildew. Small animals can be kept out by sealing larger spaces, but mold and mildew are usually the result of moisture infiltration. These can create unpleasant odors.

The best way to prevent moisture from getting in these places is by installing a vapor barrier.

Thick plastic

To prevent odors and moisture from getting in these spaces, you can buy any type of plastic sheets that have 10 mil in thickness. You can find these at any local hardware store or home improvement center.

Light

Because crawlspaces are dark places, you will need to install a light in order to see what you are doing. You will need an extension cord and a light.

Examination

Before starting to clean and measure the place, you need to inspect it. Make sure that there aren’t any metal edges or objects that may harm you or damage the barrier.

Measurements

You will now need to measure the length and the width of the crawlspace and also measure the plastic sheets. Make the necessary calculations to use the sheets in an efficient way.

Cutting the sheets

When you cut the sheets, you need to make sure that you have accounted the plumbing pipes or any heating ducts. Make the cuts in order for the sheets to fit horizontally. Try to cover the entire surface of the floor or wall.
