The Best Crawl Space Encapsulation Material for Your Home

Get a Free Estimate

Crawl space encapsulation isn’t just a long-term investment but an endeavor that will benefit your entire home. You want to make sure you get the choice of material right and hire a professional service that can do a proper installation in your Indianapolis, IN, home. If you get these two right, you’ll be able to create a clean, dry, and usable space that will serve you well for years.

Read on and find out what encapsulation system can help you achieve your goals, how much you’ll spend, where to get the best material, and why you should let professionals handle the installation.

What Encapsulation Material Should You Use?

A polyethylene vapor barrier with reinforced polyester cord is the preferred material for encapsulating a crawl space. It is available in various roll sizes and thicknesses. Installed properly, a plastic vapor barrier will lock out moisture, dust, and external air that threatens the internal conditions in your home. It will also make it more difficult for pests to get inside, and they won’t find this environment as hospitable as a damp and moist crawl space,

With the choice of material now out of the way, the next thing to consider is the thickness of the poly. Two things will guide you here. The first is the purpose of the crawl space, and the second is what kind of floor you have. If you’re going to convert the crawl space to a storage area, that means you’ll be visiting it regularly.

A 20-mil vapor barrier would be the best choice no matter how you choose to use the space. This liner offers a mix of value and a certain degree of durability. A barrier this thick can endure rough handling during an inspection and hold up well in crawl spaces with significant traffic. Likewise, you can use a poly of the same thickness on a crawl space with a concrete floor.

Also consider installing a dehumidifier if you feel concerned about internal moisture.

Where to Buy Plastic Encapsulation

You can get the 20-mil polyethylene vapor barrier from the hardware store near you. Prices can range from a couple of hundred dollars to more than a thousand dollars for the large and thicker roll size. Since encapsulation is a long-term investment, we recommend the durable 20-mil roll over the thinner 6-mil. You don’t want to be replacing your plastic barrier every two or three years, would you?

That being said, no crawl space work is DIY, and it’s best to leave the finer details to a local crawl space repair contractor in Indianapolis, IN. That way, the heavy-duty encapsulation also will be protected with a longtime warranty.

How Much to Encapsulate the Crawl Space?

Costs vary from contractor to contractor. On the lower side, it could run $5,000, and on the higher side, it could be closer to $20,000. How much you’re going to spend will depend on the size of your crawl space and its condition. If it’s dirty or damaged, you will have to clean it up first, fix rotten beams or joists, and replace damaged ducts and insulation material. If there’s mold, it has to go before installers can start sealing this space. Ensure that the crawl space is clean and in good shape before encapsulation gets underway; otherwise, you will spend more money in preparation. And that could also mean waiting for several days.

How Long Does it Take to Seal a Crawl Space?

As with every home repair project, the timeline is certainly going to be at the top of your mind because it touches on cost and your convenience. Installation can take several hours to a couple of days. We recommend that you hire professionals, as they have the right tools, knowledge, and skill. They can work faster and complete the job in good time without compromising the security of your home.

Again, we encourage you to prepare the crawl space in advance. Clean up the space so that when the contractor comes, they will have an easy time sealing it up. If you’re not sure what needs fixing, schedule an inspection and get recommendations on what repairs you should undertake.

Why Hiring a Professional Makes Sense

If you intend to encapsulate your crawl space, we advise you to hire a professional to handle the installation. True, you may have how-to videos or step-by-step materials at your disposal, but encapsulation is a delicate exercise that requires skill, knowledge, and experience. Another reason to leave this job to the pros is they’re comfortable working in confined and dimly lit spaces like the crawl space. Since they have protective gear, they won’t mind the dust and other hazards in there.
