Every wet crawl space in Avon is a slow-motion disaster for the wood structure above it. Our heavy-duty vapor barrier systems stop ground moisture permanently.
Four things our Avon 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.
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.
Homeowners in Avon, IN 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.
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 IN 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.
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 Avon, IN conditions before completing each project.
Six crawl space services that address every moisture source under your Avon 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.
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.
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 Avon, IN 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.
