The air inside your crawl space becomes the air inside your home. JCB Waterproofing and Construction's full encapsulation service seals your home's foundation level against moisture, pests, and mold.
Four things our Hobbs customers consistently point to when recommending us.
We install 20-mil reinforced polyethylene vapor barriers -- not the thin 6-mil sheeting that degrades within a few years under crawl space conditions.
We seal every penetration -- pipes, posts, and support columns -- individually so the barrier is continuous with no gaps that allow moisture to bypass the system.
Homeowners in Hobbs, IN who complete crawl space encapsulation typically notice improved comfort in first-floor rooms that previously felt cold or damp.
Wood floor joists exposed to sustained humidity above 20 percent begin to lose structural integrity within a few years -- encapsulation stops that deterioration before it becomes expensive.
The science behind crawl space encapsulation centers on moisture vapor transmission from exposed soil surfaces. Even dry-looking crawl space soil emits moisture vapor continuously at a rate that can introduce gallons of water per day into the air under your home. Traditional building practice placed foundation vents to exhaust this moisture, but research has repeatedly shown that venting in humid climates introduces more moisture than it removes, because the air flowing in from outside is often more humid than the air inside the crawl space. Sealing the crawl space and managing its humidity with a rated dehumidifier consistently outperforms venting in IN climates.
The vapor barrier is the physical core of the encapsulation system. Mil thickness matters significantly in this application: 6-mil poly is standard for short-term vapor retarders in above-grade construction, but crawl space conditions include foot traffic during inspections and maintenance, contact with rough aggregate and irregular soil surfaces, rodent activity, and exposure to moisture for decades. We specify a minimum 20-mil reinforced poly with a ripstop layer that resists puncture from debris and maintains its vapor transmission rating even if the surface is scuffed or walked on. The barrier is cut and fitted to the exact dimensions of each crawl space section, with all wall terminations run up to the rim joist and sealed with a waterproof tape rated for that adhesion surface.
HVAC performance in homes with encapsulated crawl spaces improves because the humidity load on the air conditioning system is reduced. In a vented crawl space, humid outside air is drawn under the house, rises through the subfloor into the living space, and must be removed by the air conditioning system. This hidden moisture load causes air conditioners to run longer, increases compressor wear, and reduces the effective cooling capacity of the system. After encapsulation, the crawl space humidity is maintained by a rated standalone dehumidifier that handles only the manageable internal moisture load rather than an endless supply from outside air.
Crawl space dehumidification is the final element of a complete encapsulation system. Even a fully sealed crawl space generates some internal humidity from concrete foundation walls and the residual moisture in the soil, particularly in the first season after installation when the soil is transitioning to a lower equilibrium moisture content. A rated crawl space dehumidifier sized to the cubic footage of the space maintains interior relative humidity below the threshold that supports mold growth. We specify units with gravity drain or condensate pump to eliminate the manual emptying requirement, and we set the humidistat to an appropriate setpoint for Hobbs, IN conditions before completing each project.
Complete coverage from vapor barrier to dehumidification -- everything your crawl space needs.
We cut and fit barrier material to every section of your crawl space, including around posts, piers, and columns, so no ground surface is left exposed to vapor evaporation.
Rated standalone crawl space dehumidifiers installed with gravity drain or condensate pump, sized to the cubic footage of your specific crawl space and set to maintain safe humidity levels year-round.
Sealed vents are insulated to the same standard as foundation walls so the crawl space maintains a stable temperature that reduces condensation on HVAC equipment and plumbing.
When visible mold colonies are present on floor joists, sheathing, or structural framing, we treat affected surfaces with EPA-registered fungicidal solutions before installing the vapor barrier.
Where standing water enters the crawl space during heavy rain or due to a high water table, we install a dedicated crawl space drainage system that collects and removes water before the vapor barrier is installed.
Existing crawl space access hatches and exterior doors are insulated and sealed to prevent air infiltration that would bypass the encapsulation system at its perimeter.
Our inspection produces a written findings report with photographs that you receive along with your written quote, providing a complete documented baseline of your crawl space condition.
Standing water drainage infrastructure is also installed in this phase so the crawl space floor is dry and stable before the vapor barrier goes down.
Heavy-duty vapor barrier material is measured, cut, and installed across every section of the crawl space floor and up foundation walls, with all seams overlapped and taped and all penetrations individually sealed.
A rated crawl space dehumidifier is installed, connected to gravity drain or a condensate pump, and set to the target humidity level for your Hobbs, IN climate before we complete the project.
We noticed musty smells from the first floor for years and assumed it was just an old house. After JCB Waterproofing and Construction encapsulated our crawl space, the smell was gone within two weeks and our summer electric bills dropped noticeably. Should have done this years ago.
JCB Waterproofing and Construction did a full encapsulation in one day and left the crawl space cleaner than it was when they arrived. The dehumidifier they installed has not required any maintenance beyond emptying the drip tray.
The air quality in our home is noticeably better since the encapsulation. I have less allergy issues and our HVAC is running shorter cycles. Genuinely one of the best home improvements we have made.
