Every wet crawl space in Augusta 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.
Homeowners in Augusta, GA 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 Augusta, GA, 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.
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 Augusta, GA 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.
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.
When visible mold colonies are present on floor joists, sheathing, or structural framing, we treat affected surfaces with EPA-registered fungicidal solutions before installing the vapor barrier.
Drainage channels are integrated under the vapor barrier perimeter, routing water to a sump pit with a submersible pump sized for your drainage area.
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.
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.
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 Augusta, GA 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.
