Every wet crawl space in Lockport 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.
We install 20-mil reinforced polyethylene vapor barriers -- not the thin 6-mil sheeting that degrades within a few years under crawl space conditions.
Every seam in our vapor barrier installation is overlapped and taped with purpose-made crawl space seam tape rated for the temperature and humidity range your crawl space experiences.
Sealed crawl spaces consistently show measurable reduction in heating and cooling costs because conditioned air is no longer exchanged with the unconditioned crawl space below.
We inspect floor joists, beams, and support posts as part of every assessment and flag any existing wood damage that requires remediation before encapsulation is installed.
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 NY 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.
Six crawl space services that address every moisture source under your Lockport home.
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.
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.
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.
Post-treatment borate preservative application inhibits future mold and decay fungi development on all treated wood surfaces under conditions of elevated humidity.
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.
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.
We enter the crawl space and conduct a systematic inspection of all floor and wall surfaces, document moisture meter readings at multiple locations, photograph all floor joist and beam conditions, and identify every source of water or moisture entry before recommending any course of action.
Where mold remediation is needed, we complete EPA-registered fungicidal treatment and borate application before any encapsulation materials are installed, ensuring no active mold is sealed under the barrier.
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 Lockport, NY climate before we complete the project.
Our floor joists were showing early decay when JCB Waterproofing and Construction inspected. They remediated the mold, sealed the entire crawl space, and installed a dehumidifier -- a year later the wood moisture readings are in the safe range and the floors feel solid again.
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.
