What Is Crawl Space Insulation Installation?

Grasping crawl space insulation installation requires knowing why insulating crawl space areas in your home is crucial.

Crawl space insulation is installed to stop hot air from escaping homes during the winter and turning homes into saunas during the summer. Without a properly insulated crawl space, moisture will build up, developing mold, mildew, and wood rot – diminishing a house’s structural integrity.

The mold spores in free-flowing air invade homes without proper crawl space insulation, causing unpleasant odors. These conditions can also lead to health issues like asthma and trigger respiratory problems.

Lacking crawl space insulation may also cause energy costs to skyrocket in homes in moist climates. Creates an uncomfortable living space no one likes cold feet.

While many PNW residents have insulated crawl spaces, it’s important to inspect whether or not the insulation in your crawl space is the best insulation for the particular home. Outdated or improper crawl space insulation may lead to the same problems detailed above as having no insulation.

How To Insulate A Crawl Space

Below is a detailed breakdown of how Crawl Pros insulates a crawl space.

Stage 1: Removing Previous Insulation And Cleanup

The first part of insulating a crawl space entails removing any previous insulation. Not all homes have prior insulation in their crawl spaces, but many do, so it’s important to mention this process.

Also, even if your crawl space doesn’t have prior insulation, it’ll likely require much of this work–unless your home is brand new. 

At Crawl Pros, removing previous crawl space insulation involves the following steps:

  • We put tent poles with plastic sheets over the spaces in your home that are potentially impacted by removing the crawl space insulation. We also line doorways with cardboard.

  • Our insulation installers then thoroughly clean and remove old insulation, rodent carcasses, feces, vapor barriers, and construction debris from the crawl space. 

  • Our crew seals any points of air penetration between unconditioned and conditioned spaces.

Stage 2: Installing Or Reinstalling Insulation

The next insulation component involves installing or reinstalling the insulation. 

At Crawl Pros, we assess the thickness of floor cavities. Then, we fill those cavities, starting at the floor and going until the end of the joints.

Our team uses nylon twine to cross-string the bays. Or, they hold the insulation in place with a wood lathe. The products we use have natural binders instead of formaldehyde because we’re committed to sustainable and safe crawl space insulation practices. 

Stage 3: Adding A Vapor Barrier

In this stage, we add a vapor barrier. We often install a 9 mm vapor barrier (it can be installed white or black side up.) We use tape to ensure the vapor barrier is fully secured and doesn’t move.

Our estimators might recommend fully encapsulating a crawl space, depending on the circumstances. 

Stage 4: Flood Prevention And Water Mediation

The last part of Crawl Pro’s insulation installation revolves around flood prevention and water remediation. Typically, we’ll install a sump pump. Also, we’ll add French drains in the crawl space that flow into the sump pump.

From there, we’ll install back-flow devices for water prevention, then run the pipe out of the area and into an exterior rain gutter. 

DIY Crawl Space Solutions

Integral to all homeowners looking to DIY their crawl space insulation is insulating the subfloor and lining the ground with a vapor barrier.

DIYers will need to install fiberglass insulation in the subfloor. You can place a plastic vapor barrier on the floor and join the two materials with tape.

You’ll need polyethylene plastic sheeting 6mm or thicker. It will be your vapor barrier that prevents moisture and controls humidity. 

DIYing crawl space insulation installation may be an effective solution for the basics such as sealing and protecting the entirety of the crawl space. However, it may be much more extraneous to tackle a full-encompassing project that includes preventive measures in your crawl space. DIYers may lack the knowledge, training, and equipment that professionals like Crawl Pros have in excess. When attempting any type of home repair DIY solution, make safety the top priority.
