Three Important Benefits of Crawl Space Encapsulation for Homeowners
When your HVAC kicks on, does it circulate a damp, stale smell that makes you wrinkle your nose? Do you suffer from cold or allergy symptoms that disappear while you’re at work, only to return shortly after you return home? Has your dehumidifier or sump pump been running far more than it used to? These are all signs that your crawl space is unhealthy and desperately needs your attention.
If your foundation is suffering from water intrusion, so is the rest of your house.
Acculevel has been helping people with foundation repairs and waterproofing since 1996, and we can promise you this: excessive moisture will break down just about every element of your crawlspace. This can have major consequences for the health of your family, your home, and your bank account.
The Process of Crawl Space Encapsulation
First, you have to manage the water that has been getting into your crawl space. This requires installing a water drainage system and sump pump, to effectively collect and drain the water. Once you clear that hurdle, you can then move on to encapsulation.
Encapsulation is like installing a pool liner inside your crawl space, except it keeps water out instead of in. A thick, heavy plastic is placed throughout the crawl space, over the floor and up the walls. Seams are taped and sealed, and the encapsulation sheeting is secured to the walls.
Once this is complete, foam insulation is sprayed around the perimeter at the top of the foundation, filling in the open spaces between the joists and bandboard. As a final guard against humidity, a dehumidifier is installed to keep the air clean, fresh-smelling, and dry.

The Benefits of Crawl Space Encapsulation
1. Encapsulation Will Protect Your Health
Encapsulation seals out moisture, which greatly reduces the chance of mold developing in your home. Mold is a threat to the healthiest of people, but is especially dangerous for those with allergies, asthma, or compromised immune systems. Mold exposure increases the risks of developing allergies and asthma in infants and young children because their immune systems are still growing.
The encapsulation barrier will also improve the quality of the air you breathe. It seals out the odors, vapors, and gases that come from the soil beneath your home. This is an important factor because your HVAC system circulates the air throughout the house; whatever vapors are in the crawl space will be in the air you breathe.
2. Encapsulation Will Protect Your Home
Water won’t just cause mold in your crawl space; it also degrades the structural stability of your flooring. Water and humidity contribute to wood rot, which leads to sagging floors. By encapsulating your home, you protect the structural wooden framing system. As we discuss in our article about crawl space waterproofing, the health and well-being of your home begins at the foundation level.
The encapsulation will also inhibit unwanted visitors from getting into your home. This includes damaging insects like termites and powderpost beetles. It also discourages larger invaders like rodents; a sealed environment with no access to water isn’t a good home for them.
3. Encapsulation Will Save You Money and Increase Your Home’s Value
Once the crawl space is encapsulated, you will have cleaner, drier air in your home. This makes less work for your HVAC system, increasing its efficiency and extending the life of the equipment. Depending on the size of your home and the age of your HVAC, you can expect a 10-20% decrease in your utility bills.
The new and improved crawl space will provide usable storage space for out of season decorations or clothing. Depending on your situation, this can free up closet space in your living area or eliminate the need for a costly storage unit.
All of these benefits translate to a more desirable home, which increases your resale value. It’s true not all home buyers will have an encapsulated crawl space on their ‘ideal home wish-list.’ But when faced with a choice between your well-maintained home and one with a damp and unpleasant crawl space- the odds are firmly in your favor!
