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 Bloomdale customers consistently point to when recommending us.
Heavy puncture-resistant poly barriers stay intact through decades of crawl space activity, inspection visits, and seasonal ground movement.
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.
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.
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 Bloomdale, 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.
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.
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.
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.
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 Bloomdale, OH 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.
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.
