How to Prevent Moisture in Basement Carpet

Posted on 17 October 2017 by admin (0)


Homeowners tend to prefer hardwood floors for their home in 2017 and recent years. However, carpet is still very popular. Carpet is a common choice for bedrooms, for example. But what about basements?

Homeowners should not install hardwood floor in a basement because the moisture can warp the wood. This leaves carpet or concrete as the only two options.

We prefer carpet for basements. But it requires special attention during installation in order to prevent the carpet from retaining moisture and leading to mold and mildew.

Here is how to install carpet in a basement:

(1) Vapor Barrier

In a living room or bedroom on the main floor, you would typically install a carpet pad over the subfloor and then lie down the carpet across the room. For a basement, there are additional steps.

First, you need to install a vapor barrier. This barrier should be made of mold and moisture-resistant materials. You can find several synthetic options available. This layer will lie directly over the concrete subfloor of the basement.

(2) Wood Subfloor

The next layer is a wood subfloor. The wood floor will lie over the vapor barrier and provide an additional layer of protection from the carpet pad and the carpet above.

We recommend using flat plywood boards for the wood subfloor. You will need concrete screws to fasten the wood through the vapor barrier and the subfloor.

(3) Carpet Pad

You should now place a carpet pad over the plywood subfloor. We recommend a mold- and mildew-resistant pad. This will cost a little more but will be worth the investment in order to protect the carpet. You can also purchase carpet pads that are odor-resistant too.

(4) Carpet

Now it is time to install the carpet over the previous three sublayers of flooring in the basement. We recommend an industrial fiber such as Berber for the floor. You do not want a plush fabric for the basement.

You can also consider carpet tiles for a basement. Carpet tiles are a relatively new option for home flooring. The tiles are cut in square pieces and then laid out across the floor piece by piece. This way if a piece of the carpet is damaged from moisture, you can replace the single piece instead of the entire wall-to-wall carpet.

(5) Sump Pumps

The sump pump isn’t directly related to installing the carpet but you want to be sure it is 100% operational if you plan to install carpet in your basement. If your basement is prone to flooding or pooling in the past, consider installing a dual sump pump system as an additional precaution.

You can see that there are a few additional steps to complete in order to install carpet in a basement and ensure it maintains its quality over the course of its lifetime. You can also help with proper care and maintenance which includes vacuuming and scheduling professional carpet cleaning from a local service like Champion Chem-Dry.

If the installation is completed successfully and the carpet is cared for, you will love carpet in your basement for many years.
