Encapsulating your crawlspace is definitely the way to go for a more energy efficient, comfortable and healthy home. The best way to treat your crawlspace is the same as your basement. You want to insulate around the perimeter and provide some conditioned air to help control moisture further.
Yes, bringing the crawl space into the conditioned space is generally recommended as a way to prevent crawlspace moisture problems (I assume this is what you mean by encapsulate). This means: sealing vents to the exterior. sealing the dirt floor with polyethylene sheeting (at least 6 mil), or concrete.
Beside above, what are the benefits of encapsulating your crawl space? Benefits of an Encapsulated Crawl Space
- Breathe easier.
- Reduce the chances of costly floor repairs.
- Enhance comfort.
- Lower energy bills.
- Make your heating & cooling equipment and ducts last longer.
- Qualify for rebates and tax incentives.
- An encapsulated crawl space is an attractive selling feature.
Subsequently, question is, how much does it cost to encapsulate a crawl space?
A homeowner will spend $5,500 on average to install a crawl space encapsulation system. Total costs, including supplies and professional labor, range from $1,500 to $15,000. Overall price will vary based on factors like the size and condition of the crawl space, contractor rates, and materials used.
Does an encapsulated crawl space need a dehumidifier?
Every encapsulated crawlspace needs a drying mechanism. Our favorite is a dehumidifier (we’ll explore why in just a moment), but it’s common for contractors to dry your crawlspace using the “supply air” method. In some homes, supply air may do a good job of drying out the crawlspace.
Does crawl space encapsulation add value?
An encapsulated crawl space can add value to your home because of the benefits it provides. Crawl space encapsulation not only prevents moisture from penetrating your home, but it helps create more safe, secure storage space.
Does an encapsulated crawl space need insulation?
You don’t need to insulate an encapsulated crawl space. Crawl space insulation can be applied between the joists or on the walls of the crawl space. If the crawl space is vented then joist insulation is recommended. If the crawl space is encapsulated either can be used but we recommend insulating the block walls.
Is a vapor barrier necessary in crawl space?
Without a vapor barrier, the moisture that comes in through the soil can lead to electrical shorts, which is a fire hazard. That water can also cause your plumbing to rust and eventually break over time. Installing a vapor barrier in your crawl space will keep the area dry and healthy.
When should you encapsulate your crawl space?
One off the most important jobs of encapsulation is to provide a barrier against moisture. If your humidifier is running constantly, you have a damp odor, or the crawlspace is flooding, the space has not been properly sealed. This is most often caused by the contractor cutting out steps, such as proper taping.
Should I seal crawl space vents?
Should I seal off crawl space vents or keep them open? Some homeowners seal off crawl space vents year-round in order to stop termites in the summer, heat loss in the winter, and moisture buildup that can lead to mold growth; others open and close the crawlspace vents with the season.
How do I dry my crawl space?
4) Keep moisture out of your crawl space with crawl space encapsulation. Install a sump pump to remove any excess moisture, if needed. Lay a thick, 20mil vapor barrier, like CrawlSeal, over the floor and up the wall. Install an energy-efficient crawl space dehumidifier to keep the space dry.
Is crawl space encapsulation tax deductible?
The cost of floor and wall material to encapsulate a 1,500 square foot crawl space averages about $1,500. As part of the American Recovery and Reinvestment Act, a tax credit equal to 30% of the cost of improvements designed for the specific purpose of making their homes more energy efficient is available to homeowners.
What do home inspectors look for in crawl space?
Mold and/or mildew, whether on the walls, on items stored in the attic or crawl space or a musty smell. Potential wiring or plumbing problems. Foundation issues, whether cracks, settling or shifting. Evidence of dangerous materials, like asbestos or urea-formaldehyde.
What is encapsulation of crawl space?
Crawl space encapsulation, or sealing, is the treatment that building scientists recommend to turn a damp, dirty, moldy crawl space into a clean, dry space where mold can’t grow.
How much does it cost to spray foam a crawl space?
Not every crawl space is made the same, so the size of the area to be insulated is the main contributor to the cost of the spray foam insulation project. The average cost to insulate a crawl space with spray foam is between $1,200 and $2,500.
Why would you encapsulate a crawl space?
Encapsulation is the process of completely sealing your entire crawl space in a white plastic. The purpose of encapsulation is to reduce the moisture in your crawl space, reducing your risk of mold. It also makes for cleaner air in your crawl space, which you share air with.
Does crawl space encapsulation increase home value?
Crawl space encapsulation helps to stabilize temperatures in the crawl space — and ultimately, throughout the rest of your home. This reduces stress on heating and cooling equipment and can lower energy costs by an estimated 10% to 20%.
Is it OK to cover crawl space vents?
With this in mind, crawl space encapsulation will NOT work without closed vents. The entire system is in jeopardy if your crawl space isn’t sealed off from the outside air correctly. Open vents create high levels of moisture, condensation, and humidity that will be detrimental to your home’s foundation.
