Moisture causes a lot of damage in crawl spaces. It floods in through open vents, rises from the earth, and seeps in through foundation walls raising the relative humidity in the space. This results in damaged insulation, mold and mildew growth, high energy bills, drafts inside the home, cold floors, and homeowners may notice high humidity and musty odors in the home as well.
We removed the old vapor barrier and debris then sealed the vents, penetrations through the foundation walls to the outside, and the sill plate. Next, a CleanSpace vapor barrier is installed, sealing the crawlspace from the earth. Our technicians then apply closed-cell spray foam to the foundation walls and rim band. Finally, a new crawl space door is installed.
This Henrico, VA client contacted us because they wanted to address the insulation in their crawl space. Moisture had caused damage to the fiberglass insulation and it was sagging and falling to the ground. The unsealed, vented crawl space was allowing moisture to flood in and cause damage to the insulation as well as mold and mildew growth.
The homeowner wanted to not only reinsulate the crawl space, but they also didn't want to do it again in a few years. After reviewing their options, they opted to encapsulate the space. The crawl space was cleaned out and treated with an antimicrobial. Then, a new vapor barrier is installed sealing the crawl space off from the earth's moisture. Our team then air seals the space by blocking and sealing all vents and sealing any penetrations through the foundation wall to the outside.
Next closed-cell spray foam is applied to the foundation walls and rim band. A SaniDry Sedona dehumidifier is installed to control the relative humidity and help prevent future microbial growth. Finally, an interior friction-fit door is installed to air seal and insulate behind the exterior door, and an Everlast exterior crawl space door is installed on the outside.
The conditioned space shared with these knee walls was sweltering in the summer and freezing in the winter due to sharing a wall with an unconditioned attic space. We installed insulation in the wall cavities and covered it with Tyvec to create an air barrier and better insulate the wall. We also installed insulation on the floor of the space to prevent air loss from the room below.
This crawl space had moisture issues and the homeowner complained about the floor creaking. We found that the crawl space had moisture entering through open crawl space vents, the exposed earth, and through porous block walls.
The homeowner opted to seal the crawl space, remove the old vapor barrier and insulation, install a new vapor barrier and seal it at the seams and along foundation walls, sealing all vents, and insulating the foundation walls with closed-cell spray foam. And finally, a SaniDry Sedona Dehumidifier was installed. This system helps to seal the crawl space from outside influence including moisture, which had caused much of the damage in the crawl space. The dehumidifier controls the relative humidity, helping to prevent future mold growth.
This detached garage in Chesterfield, VA needed insulation, so the homeowner called us to perform a free estimate and schedule the installation. We installed 14-inches TruSoft blown cellulose insulation with an R-49 value. A dam was built to contain the insulation and prevent it from falling into the storage deck.
