Every wet crawl space in Rensselaer is a slow-motion disaster for the wood structure above it. Our heavy-duty vapor barrier systems stop ground moisture permanently.
What makes our encapsulation installs last decades, not years.
Heavy puncture-resistant poly barriers stay intact through decades of crawl space activity, inspection visits, and seasonal ground movement.
A barrier with unsealed seams and penetrations stops only a fraction of the moisture it could -- our sealed system approach eliminates every bypass path.
HVAC equipment running in an encapsulated crawl space operates at higher efficiency because humidity does not overload the system's dehumidification capacity.
Protecting the wood structure of your home from moisture is the most cost-effective maintenance you can invest in, and crawl space encapsulation is the most efficient way to accomplish it.
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.
Seam treatment is what separates a professionally installed system from a DIY job that looks similar from a distance. Every seam in our installations is lapped a minimum of 12 inches and taped with a 4-inch crawl space tape rated for the temperature and humidity cycle of your crawl space. Penetrations for plumbing pipes, support columns, and structural posts are individually wrapped with additional barrier material and taped circumferentially so the junction between the pipe and the barrier is fully sealed. A barrier with unsealed seams can still allow significant moisture vapor migration because vapor follows the path of least resistance -- which is any gap, however small.
Wood rot in crawl space framing begins when wood moisture content exceeds approximately 19 to 20 percent and stays elevated long enough for decay fungi to establish. Decay fungi are present in virtually all soil and all crawl space environments -- the limiting factor is not their presence but the moisture level that allows them to become active. Floor joists exposed to a wet crawl space can develop visible decay within a few wet seasons, and the damage is progressive: soft spots in floors, squeaking from weakened joists, and in severe cases structural deflection in floor systems become evident. Our assessments photograph and document all floor joist and beam conditions so you understand the current state of your structure before and after encapsulation.
Mold remediation is frequently required in conjunction with encapsulation when visible mold colonies are already established on floor joists, subfloor sheathing, or HVAC components in the crawl space. We assess mold extent as part of every inspection and provide a remediation plan that addresses existing growth before the encapsulation barrier is installed. Installing a vapor barrier over active mold does not eliminate it -- the mold must be treated first to prevent it from continuing to develop and produce airborne spores that migrate into the living space. Our remediation process uses EPA-registered fungicidal treatments applied to all affected wood surfaces, followed by a borate-based preservative application to inhibit future growth.
Complete coverage from vapor barrier to dehumidification -- everything your crawl space needs.
20-mil reinforced poly barrier installed across the entire crawl space floor and up foundation walls, sealed at all seams and penetrations for complete moisture control.
Dehumidifier placement and airflow direction are planned to ensure even coverage of the entire sealed space, with no humidity pockets that allow localized moisture buildup.
Existing foundation vents are sealed with rigid foam insulation cut to size and adhered with spray foam to eliminate the primary pathway for outside humid air to enter the crawl space.
Post-treatment borate preservative application inhibits future mold and decay fungi development on all treated wood surfaces under conditions of elevated humidity.
Drainage channels are integrated under the vapor barrier perimeter, routing water to a sump pit with a submersible pump sized for your drainage area.
We install weatherstripping and rigid foam panel inserts on all access points sized to provide an airtight fit that maintains the pressure balance of the sealed crawl space.
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.
Foundation vents are sealed with rigid foam insulation and spray foam adhesive, and the crawl space access hatch is fitted with an insulating door seal panel.
A rated crawl space dehumidifier is installed, connected to gravity drain or a condensate pump, and set to the target humidity level for your Rensselaer, 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.
The crew was thorough and professional. They explained what they found, showed me photos, and completed the work exactly as quoted. The crawl space is completely dry now and looks professionally done.
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.
