Moisture in the crawl space can contribute to musty odors throughout the home. We address the moisture problem and improve conditions below the house so the space stays drier and cleaner.
An unsealed crawl space can allow outside air and moisture beneath your home. Encapsulation and insulation can help create a more controlled space below your floors.
Open vents, gaps and exposed crawl spaces can create entry points for pests. Encapsulation helps seal the space, but active pest problems should be handled by a pest-control professional.
Floors above the crawl space that dip, bounce or feel uneven can point to weakened supports below. We inspect the structure and recommend the right repair to stabilize the floor system.
Excess humidity in the crawl space can lead to condensation, odors and damp building materials. We identify the moisture source and recommend ways to better control the space.
Based on crawl space projects completed by Basements Plus over the past year and our current pricing, most encapsulation projects range from $10,000 to $15,000.

The crawlspace looks and smells like new!

Commonly asked questions about crawl space encapsulation and repair
Cold floors above a crawl space are usually caused by air movement, not a furnace problem. Warm air rising and escaping through the top of your house pulls replacement air in from your crawl space below, a phenomenon called the stack effect. In winter, that pulls cold outside air up through the floor above your crawl space, making it feel cold regardless of how well your furnace is running.
It depends on where the moisture is coming from. A sump pump removes collected water, while a dehumidifier controls moisture in the air. Some crawl spaces need one, some need both and others may only require proper sealing and insulation.
During your inspection, we evaluate standing water, drainage, humidity, and existing equipment before recommending a solution.
No. Our crews need at least 24 inches of clearance to safely access and complete crawl space work.
Our inspection will confirm whether your crawl space is accessible and whether our repair and encapsulation solutions are appropriate for the problem.
Yes. An unsealed or poorly insulated crawl space allows cold, damp outside air to enter beneath your home. That can make the floors above feel cold and force your heating and cooling system to work harder to maintain a comfortable temperature.
Sealing air leaks, insulating the crawl space walls and controlling moisture can make the floors above more comfortable and reduce unnecessary energy loss. The exact effect on your energy bills will depend on your home, existing insulation and HVAC system.
Most crawl space encapsulation projects take two to four days once work begins.
The exact timeline depends on the size and condition of the crawl space, accessibility, whether the project includes drainage, a sump pump, insulation, structural repairs, or a dehumidifier. Before work begins, your project coordinator will explain the scope and expected installation schedule.
Based on the crawl space projects we completed over the past year and our current pricing, most encapsulation projects range from $10,000 to $15,000.
The final cost depends on the size and condition of the crawl space, accessibility, material removal and whether the project requires drainage, insulation, a sump pump, structural repairs or a dehumidifier. Our 21-Point Inspection identifies the source of the problem and provides a written recommendation and price for your home.
Yes. We offer several financing options for qualified homeowners who prefer to spread the cost of their basement project over time.
