Before & After Photos

This home had water seeping into its crawl space. The high humidity and warm temperatures in our area result in microbial growth on joists, falling insulation, cold floors, and poor indoor air quality in many crawl spaces and homes. To repair this crawl space, we cleaned it out, treated the joists with an antimicrobial, installed a drainage system and sump pump, laid down and sealed a 20mil vapor barrier to the walls, piers, and floor, and insulated the walls with spray foam. 

This homeowner in Gloucester Point was using an old sump hole to help collect any water that infiltrated their basement. Unfortunately, these sump holes are useless in collecting any water seeping through the basement foundation walls. The old pump could not handle the amount of infiltrating water, and there was nothing in place to direct the water to the sump pump. Our team was sent out to install a number of solutions to help combat water infiltration. We mechanically fastened a durable 10-mil CleanSpace Light vapor barrier over the walls to help protect the basement from water seeping through the walls. This also collects any infiltrating water and sends it down to a WaterGuard XL drainage system that we installed within a trench leading to our sump system. The sump system itself is what we call a SuperSump Plus system. It used our TripleSafe twin line basin with a single cast iron 1/3 horsepower Zoller pump. This reliable sump pump can handle 2,650 gallons per hour smoothly and quietly. It uses a mechanical float switch and will resist clogging more efficiently than the old sump. The basin contains a WaterWatch Alarm system, a battery backup pack,  and an airtight lid. Any water collected in the WaterGuard XL system will be directed straight to the SuperSump Plus, then it will be distributed out of the home via hose line to a determined location away from the home's foundation. The homeowners can feel at ease knowing that this sump pump system will help to keep their basement dry and clean for years to come.

This Irvington, VA crawl space had microbial growth on floor joists, was missing insulation in many areas, and the vapor barrier was unsealed, allowing moisture from the earth to impact the crawl space. After cleaning all of the old materials and debris out, we treated the floor joists with Shockwave Antimicrobial and sealed the crawl space from the earth’s moisture with the CleanSpace Vapor Barrier. We sealed all outside penetrations to the foundation, including air gaps such as vents, the sill plate, and rim and band. Closed Cell Spray Foam is ready to be applied to the walls and a SaniDry Sedona Dehumidifier will be installed to control the relative humidity. The system will help protect the home from microbial growth and make the home more comfortable, improve indoor air quality, and reduce energy bills.  

The exterior access to this crawl space was in good shape. However, it was uninsulated and it was not air tight. This means it allowed heat to radiate in and warm humid air to flow into the crawl space. We installed an interior friction fit door behind the access door. The interior door provides an R-10 of insulation and air seals behind the crawl space access. This seals a big hole that adversely impacts the crawl space otherwise. 

These homeowners in Newport News, Virginia were experiencing water infiltration within their crawl space. They decided to call TDC out to help seal and encapsulate underneath their home. As shown by the pictures below, we focused on the crawl space entrance door, which allowed the outside air and moisture to seep through its cracks and affect the relative humidity. We installed an Everlast Door to replace the existing wood door, which will help to keep any outside influence from penetrating through the entrance. This Everlast Door is a custom-fit PVC panel with a pressure-treated wood frame and "T-head" toggle bolts. The duality of the door allows for easy access but plenty of sealing and protection when it comes to leakage.
