Mold colonies in crawl spaces originate at ground level and migrate upward through your home's air supply. JCB Waterproofing and Construction installs certified encapsulation systems that cut off moisture at the source.
Four things our Honeoye Falls customers consistently point to when recommending us.
Our material specs match what commercial builders require, not the minimum code standard for residential construction.
A barrier with unsealed seams and penetrations stops only a fraction of the moisture it could -- our sealed system approach eliminates every bypass path.
Homeowners in Honeoye Falls, NY who complete crawl space encapsulation typically notice improved comfort in first-floor rooms that previously felt cold or damp.
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.
Crawl space encapsulation is the process of sealing a home's crawl space against outside air and ground moisture by installing a continuous vapor barrier on the floor and walls, sealing all vents and penetrations, and managing the internal humidity of the sealed space with a dedicated dehumidifier or conditioned air supply. The result is a semi-conditioned space that behaves like a dry indoor environment rather than an extension of the outside soil -- eliminating the ground moisture evaporation that is the primary driver of crawl space mold and wood rot. In Honeoye Falls, NY, where soil moisture conditions fluctuate significantly with the seasons, encapsulation provides consistent protection year-round that passive venting strategies cannot match.
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 Honeoye Falls, NY conditions before completing each project.
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.
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.
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.
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.
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.
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 Honeoye Falls, 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.
I got four quotes and JCB Waterproofing and Construction was the only company that gave me a written spec listing the mil thickness of the poly they were installing. That transparency is why I chose them and their work backed it up completely.
