Crawl Space Sealing – A Professional Guide

crawl space sealing

If you have a crawl space in your home, it’s essential to seal it properly in order to prevent pests and other critters from getting in there. A crawl space that is not sealed can also let in cold air in the winter and hot air in the summer, which can cause your energy bills to skyrocket. Crawl space sealing can also help protect your home from moisture damage, too.

How can you seal your crawl space? Is it expensive to do so? We’ll answer these questions and provide everything you need to know about sealing your crawl space to preserve your home.

What is Crawl Space Encapsulation?

Crawl space encapsulation seals the crawl space to create a vapor barrier between the outside environment and the living area above. This is usually done by installing a heavy-duty moisture barrier on the floor and walls of the crawl space. The purpose of encapsulation is to prevent moisture, pests, and mold from entering the home through the crawl space.

Investing in a crawl space encapsulation system can also help improve the home’s energy efficiency by providing an air seal. Crawl space encapsulation cost is usually calculated per square foot and usually ranges from $2-4 per square foot.

Crawl space encapsulation is not a cure-all for every home. Each situation is unique, and it is essential to consult with a professional before undertaking any work.

Is Sealing a Crawl Space a Good Idea?

In order to protect your home from moisture, a sealed crawl space is a must. This area between the ground and the first floor of your home is especially vulnerable to moisture because it’s typically not well-ventilated.

When moisture seeps into your crawl space foundation, it can lead to mold growth, wood rot, and a number of other problems. A damp crawl space can wreak havoc on your home and your budget!

Crawl space encapsulation is known to provide improved indoor air quality and can improve your family’s overall health. You’ll also be able to keep the warm air in your home from escaping through the crawl space. As a result, you’ll be able to save money on your heating bills.

An encapsulated crawl space can even help keep insects and rodents out of your home. So if you’re looking for a way to protect your home from moisture, sealing your crawl space is a good option.

How Much Does it Cost to Seal Your Crawl Space?

The cost of sealing your crawl space depends on several factors, including the size of the area, the type of sealant used, and the number of entry points. A small crawl space can be sealed for as little as $200, while a more prominent space may cost up to $2,000 or more. The money that you invest in the project will be well worth it in the end since an unsealed crawl space can cost even more in the end.

A simple rolled-on sealant will be less expensive than a spray-on sealant, but it will not last as long. The number of entry points is another important consideration. If there are many cracks and holes in the foundation walls, it will take more sealant to fill them all in. If you need to replace floor joists, add a sump pump, or add crawl space vents, you will need to calculate these costs into your overall bill.

Can You Seal Your Own Crawl Space?

Many homeowners choose to seal their crawl space themselves to save on costs. But sealing a crawl space can be difficult and dangerous if you are unfamiliar with the process.

Not only do you need to ensure that the crawl space air is adequately ventilated, you also need to take precautions against mold and mildew growth. It is generally best to leave this job to a professional who has the experience and expertise to do the job right.

How Do You Seal a Crawl Space?

If you do decide to DIY the project, make sure you prepare ahead of time and take the proper steps to ensure that you completely seal the space. Start by inspecting the perimeter of your crawl space for cracks or gaps. An easy trick is to light a candle and see where along the walls the flame flickers. If it does, you may have a draft coming in. Mark all of these spots so you can come back and fill them in using caulk or expanding spray foam insulation.

Next, lay down a layer of plastic sheeting on the floor of your crawl space. Make sure the sheeting extends up the walls and is securely taped. Finally, install a vapor barrier on the walls of your crawl space. This will help to prevent outside air moisture from seeping in and damaging your home. With a little time and effort, you can seal your crawl space yourself and keep your home safe and dry.

How Long Does it Take to Seal a Crawl Space?

Having your crawl space encapsulated can usually be done in a day or two, depending on the size of the project and whether you plan to do it yourself or hire a professional. If you’re unsure about what needs to be done, it’s always best to consult with a professional. They will be able to assess the situation and give you an estimate of how long it will take. With a bit of planning and patience, you can have a dry, healthy crawl space in no time.
