Located just north of the 10th hole at Franklin Bridge Golf Club, this two story colonial
style Franklin home was in need of some improvements to its unseen underbelly. Inspection
photos tell the story of standing water around the perimeter of the crawl space. This water
seepage was fueling microbial growth on exposed areas of the floor system. Insulation, heavy
with moisture, was sagging under the added weight. While fiberglass insulation can perform
quite well in a wall cavity, exposed to crawl space moisture, it invariably fails. So, the
homeowner reached out to us to see what the options were.
We “teed off” the project by removing the moisture damaged insulation and
remediating the growth on the floor system. We then sealed pipe penetrations through the
foundation walls that were allowing water to seep into the crawl space. Our white virgin
polyethylene vapor barrier was then installed to encapsulate the bare soil and was bonded to
the walls with a band of spray foam insulation for a vapor tight seal. While we ALWAYS
recommend dehumidification, on this project the homeowner asked us to leave the crawl space
vented from the outside. This said, a dehumidifier could be added at a later date. Unlike many
newer homes, the vents at this house benefited from cross communication, providing some
positive air flow through the crawl space.
