Has your power bill been going up recently?

Thinking it may be time to add some crawl space insulation?

Making the right adjustments to your crawl space is essential if you want to keep your home comfortable and to make your power bill stay down. However, if you've never insulated a crawl space in your home before you may not know what to expect.

Luckily, we're here to help. Below we'll give you our guide to effectively insulating your crawl space.

1. Insulate the Right Places

The first step toward insulating your crawl space is to know which spots need the most insulation.

Plumbing pipes, HVAC ducts, and walls will usually need to be insulated well. However, If your crawl space is self-ventilated then you'll only want to insulate the ceiling but not the walls.

Make sure to consider your space carefully and insulate any spots that need it well. Each crawl space is a little bit different, so your home's needs may vary compared to others.

2. Prevent Crawl Space Air Flow

When insulating your crawl space, you should also make sure that you seal the air flow and make sure it is isolated from the rest of your house.

Hatchways to the exterior should be sealed as should any vent openings. Be sure to seal ventilation ducts or grills or remove them completely. Additionally, you should also use a foam sealant to seal rim joists and seals.

Sealing up these areas will help prevent air from getting in from outside and will play a big part in improving the overall air quality inside your home.

3. Choose the Right Type of Insulation

In addition to insulating the right places you also need to choose the right type of insulation to use.

The insulation you use should be strong to enough to resist water damage, so fiberglass or cellulose insulation won't fit the bill. Instead, using rigid foam insulation can be a good choice and won't allow water and air to pass through. It will also be less likely to foster mold.

4. Get Rid of Water Sources

In addition to the insulation itself, you'll want to do everything in your ability to eliminate any sources of water and moisture that are in your crawl space. A crawl space drainage system can be a big help and can make it a lot easier for your home to stay dry. 

Drainage matting for a dirt floor can also be beneficial. Additionally, you may even want to get a crawl space dehumidifier to help eliminate moisture as well.

5. Install a Vapor Barrier

Installing a vapor barrier is also a great idea and can also improve the condition of your crawl space. A vapor barrier can help to control mold, flooding, and odors, and can also help to make sure that less draft climbs into your home. It will also help to reduce air flow.

Using a vapor barrier can be a big help in improving your crawl space, so you'll want to consider using one if you want your mind to be as worry-free as possible.
