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 Bloomville customers consistently point to when recommending us.
Our material specs match what commercial builders require, not the minimum code standard for residential construction.
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 Bloomville, OH 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.
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 Bloomville, OH, where soil moisture conditions fluctuate significantly with the seasons, encapsulation provides consistent protection year-round that passive venting strategies cannot match.
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.
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.
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 Bloomville home.
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.
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.
We take final moisture readings and photograph the completed installation before issuing your written warranty documentation and maintenance schedule.
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.
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.
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.
