Before & After Photos

As part of air sealing and insulating their attic, this home had several recessed lights or "can lights." These lights are a HUGE culprit of conditioned air loss in a home. To air seal these lights while protecting the insulation from the heat the housing can give off, we use rockwool can light covers that are sealed with foam. 

While it's often hard to see what dense packing between floors or exterior walls looks like, these photos show how our techs access the floor (or wall) cavities to fill them with cellulose insulation. A hole is made to fit the hose and then our technician packs the floor cavity with insulation. when complete, this makes a big difference in heat transference for the room above the garage, keeping it cooler in the summer and warmer in the winter. 

This Doswell, VA homeowner reached out to us after noticing issues with their crawl space insulation. Upon inspection we found that the insulation was damaged by moisture and falling away from the floors, there was microbial growth on the floor joists, and signs of moisture infiltration on the liner. 

Simply replacing the insulation would mean that the homeowner would incur the same issue in a few years and need to replace the insulation again. We needed to address what was causing the insulation damage. We removed all of the debris and old material, treated the mold and mildew growth with an antimicrobial, installed a CleanSpace Vapor Barrier, air sealed the crawl space, and applied an R-10 of closed-cell spray foam to the foundation walls. 

We met this homeowner at a home show, where they asked us to come to inspect their crawl space because they were interested in encapsulating it due to moisture and mildew-mold concerns. This section of the crawl space is under an addition. The vapor barrier is unsealed, allowing moisture to rise from the ground and contribute to high relative humidity. Microbial growth is beginning on the floor joists and the fiberglass insulation is beginning to sag and fall.

The old materials have been removed, vents sealed, and the sill plate and rim band have been sealed as well. The CleanSpace vapor barrier has been installed with all seams overlapped and sealed. The moisture barrier is also run up the walls 6-8 inches above outside grade. The walls are prepped for spray foam insulation to be applied. 

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.
