Some reasons you might consider encapsulating your crawl space are if you notice a pest problem, excess mold and mildew, your floors are soft or buckling, there are cracks within your foundation, or your heating and air conditioning costs are extremely high.

What You Need For Crawl Space Encapsulation
There are a few steps that need to be taken in order to properly encapsulate your crawl space. They include insulation, a vapor barrier, a dehumidifier, and sealing.
Special Insulation
Proper insulation of your crawl space will help prevent any air leakage, maintain air quality, and drastically reduce your HVAC costs by increasing your home’s energy efficiency.
Crawl space insulation cost depends on the type of materials you will be using.
There are a few varieties of material you can use for insulation. They are open-cell spray foam vs. closed-cell spray foam, rigid foam, and batte insulation.
Open-cell spray foam and closed-cell spray foam can cost between $1.00-3.50 per foot. We DO NOT RECOMMEND spray foam insulation of any kind in a crawl space encapsulation because it is nearly impossible to remove for future repairs if needed.
We recommend using a ‘crawl space approved’ rigid foam board to insulate the walls of the crawl space which costs about $2.50-3.00 per linear foot (24″ walls).
Batte insulation is a traditional and popular option as it costs $0.60 to $1.10 per square foot but it is flawed because it can be damaged by moisture and overtime possibly have mold.
For the best crawl space insulation cost it is best to invest in your foundation walls to prevent any moisture or air leaks and help you cut on energy costs.
Vapor Barrier and Seal
It is important to use a premium vapor barrier in the process of encapsulating your crawl space as it lines the floor to keep the space dry.
A vapor barrier helps prevent mold and mildew, rotting wood, and rusted metal as it works as a vapor diffusion retarder.
Any electrical equipment or plumbing will be protected by a vapor barrier from breaking down due to excess moisture.
The vapor barrier cost depends on how thick it is. You want to choose a thick material to help prevent any moisture and tear to the barrier.
The thickness of a polyethylene plastic sheeting is between 6 to 20 mils (1 mil = 0.001 inches). A 6 mil thick sheet is $0.05- $0.20 and a 20 mil premium vapor barrier ranges between $0.40 to $0.60 per square foot.
On top of the vapor barrier cost, you will also be required to purchase waterproofing tape to help secure the barrier which costs a minimum of $18 per roll.
Once your vapor barrier is installed you need to seal exterior vents and air leaks to help the effectiveness of the vapor barrier and insulation.
Sealing includes vent covers which cost $10-20 each and a sealed crawl space access door that costs $60-150 each.
Crawl Space Dehumidifier
Finally, the dehumidifier must be designed for crawl spaces which costs between $1,000-2,000 each and requires electrical power, which is usually included in an encapsulation for $300-500 each.
Other expenses include lights, permit fees, flood vents, and other potential items.
How To Reduce Crawl Space Encapsulation Costs
Some tips to save money on the repair and encapsulation of your crawl space is to do some of the work yourself ahead of time.
But make sure you still include a professional so that problems such as mold, drainage, and pest problems are properly addressed.
Some work to do ahead of time is to clean out the crawl space yourself. Cleaning out any construction materials, old junk, or plant growth and disposing of these items yourself can save you money in labor.
When hiring an installation company, get 2-4 estimates to ensure you are not charged an excessively high fee.
What Are the Benefits of Crawl Space Encapsulation?
Encapsulating your property’s crawl space comes with a wide range of benefits. Let’s take a closer look at some of these here.
Save On Heating and Cooling Bills
Crawl space encapsulation provides a layer of insulation. This helps to make your air conditioning and heating more efficient. That means lower monthly energy bills, something that is always welcome.
Increase the Value of YourProperty
Prospective property buyers are likely to be willing to pay more for an encapsulated crawl space. If you are open to selling your property at somepoint, this project can help make it more attractive to buyers and increase the asking price.
Reduce the Risk of Mold
Crawl space encapsulation helps to protect properties from mold by creating amoisture-proof barrier. Mold can be a major health risk to both humans and animals, including causing lung and eye irritation.
Protect Your Home From Pests
An encapsulated crawl space helps to deter pests (such as insects and rodents). While it may not completely stop them, the proper installation of a vapor barrier is a good deterrent to pesky creatures such as mice and co*ckroaches.
Improve Indoor Air Quality
A good percentage of the air you breathe in your home comes from the crawl space. Therefore, it’s important to make sure that the area is properly sealed. By improving your home’s indoor air quality, you and your family will face fewer issues with allergies, too.
