Every wet crawl space in Silver Springs 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.
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.
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.
Protecting the wood structure of your home from moisture is the most cost-effective maintenance you can invest in, and crawl space encapsulation is the most efficient way to accomplish it.
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 NY climates.
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 Silver Springs, NY conditions before completing each project.
Six crawl space services that address every moisture source under your Silver Springs 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.
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.
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 Silver Springs, NY 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.
