If it's not inside the house, it doesn't matter.



A damp and moldy crawl space can cause structural damage to your property, rotting wood framing and degrading your insulation, especially if it's fiberglass. It can also attract insects, dust mites and other pests.

There's also the fact that up to 40% of the air you breathe on the first floor comes from the crawl space! The poor quality air caused by excess moisture in your crawl space, the appearance of mold and mildew, and other allergens are still hurting you.

Why does this happen?

The air from the crawl space or basement gets to the first floor due to something called the stack effect (or chimney effect).

The warm air of a home rises and is expelled through the attic. That air must be replenished. From where? Some of it comes in through doors and windows but most comes from the basement or crawl space.

Get a Clean and Dry Crawl Space

Excess moisture is one of the main issues with crawl spaces and you must take the necessary precautions to avoid damages caused by this. Any water accumulated in your crawl space, will travel upward, going through the floorboard, drywall and insulation. This can cause severe safety and health problems for you and your family.

Crawl Space Encapsulation or a Vapor Barrier Installation can keep excess moisture at bay, helping to prevent problems with mold and other health issues.

Vapor Barrier Installation vs. Crawl Space Encapsulation

At Alligator Insulation we have the experience and expertise to offer you both services.

A vapor barrier installation or encapsulation in your crawl space can stop hundreds of gallons of ground water per year from entering and damaging your home.


A vapor barrier installation prevents moisture from evaporating into the crawl space, keeping it dry and avoiding the appearance of mold and mildew.

This installation process consists in laying down 6mm black plastic called Visqueen throughout the floor. It’s important to highlight that vents aren’t sealed during this process.

If paired with a good waterproofing system, moisture in the crawl space can be completely avoided before it causes any problems.

Crawl space encapsulation is a great option to turn a moldy, dirty, damp crawl space into a dry and clean space.

The difference between vapor barrier and encapsulation is that during this process the entire space is sealed in white plastic, including vents, seams and junctions. This makes your crawl space 100% waterproof, reducing all risks of mold and saving up to 20% in your energy bill.

An encapsulation service may also include the installation or replacement of floor and air ducts insulation.

Why Get Air Ducts Insulation?

Close to 25% of the energy you use to cool your home disappears through leaky ductwork.

You’re wasting your money.

The best way to reduce this is to get duct insulation for your crawl space.

You don’t heat or cool your crawl space. It’s an unconditioned space. If you have ductwork there, in summer these ducts are significantly hotter than the inside of your home. The cool air of your A/C unit will get warmed up when it passes through the hot ducts. This is what makes your energy bill skyrocket.

Leaky ducts are also a problem as they can create indoor air quality problems. Drawing crawl space air into the air supplied to the living space can introduce allergens and other air quality issues.
