Energy-Saving Crawl Space Repair Featuring TerraBlock Insulation in Blanchester, OH
Challenge
This homeowner knew they were in their forever home and wanted their crawl space to reflect that. Their goals were simple but important: stop mold and moisture from creeping in, cut down on expensive energy costs, and make sure the crawl space would last as long as the home itself.
Solution
We began by giving the crawl space a complete cleanout. All loose debris and old fiberglass insulation were removed, along with gravel that made the ground uneven. From there, we dug a pit for the SmartPump system, paired with an UltraSump 4 battery backup for extra protection.
With the pump in place, we rolled out drainage matting to handle groundwater and prevent the need for traditional gravel drains. Next came the special part of this project: TerraBlock foam insulation on the crawl space floor. Unlike fiberglass, TerraBlock cannot hold moisture, and with its R-3.2 insulation value, it makes the crawl space much more energy efficient and comfortable to access.
On top of the TerraBlock, we installed our CleanSpace liner across the floors and walls, creating a tough vapor barrier that locks out moisture for good. For added insulation, we attached SilverGlo panels to the walls and applied spray foam to the band boards.
To finish, we sealed off the old sump pump with an airtight lid (custom-supplied by the homeowner) and added another UltraSump 4 backup for complete peace of mind. We also installed vent covers to block outside air and a LawnScape discharge outlet to camouflage the discharge outlet in the yard.
Result
The end result is a transformed crawl space that provides the homeowner with dry, usable storage, majorly improved energy efficiency, healthier air throughout the home, and the assurance that their forever home now has a crawl space built to last just as long.
