Crawl Space Repair Before & After Photos

We recently finished a full crawl space makeover to help make this area cleaner, drier, and better protected for the long term. First, we installed a heavy duty liner system to seal off the space and keep out moisture, making sure everything was tightly secured around the walls, footings, and insulation. To help with drainage and make the ground more comfortable for storage, we laid down a special mat under the liner and brought it up along the lower walls. We also added insulation around the rim of the crawl space to help improve energy efficiency. Next, we treated all the wooden and organic surfaces to prevent mold, gave the space a good cleaning including wiping down the tops of heating ducts and pipes, clearing out spider webs, and removing any loose debris. We also repaired a crack in the foundation by injecting it with a flexible sealant and reinforcing it with a strong material to keep it stable and dry.

Clean-up (fiberglass removal) and replaced with air board rigid insulation, installation of drain mat with cleanspace vapour barrier, replace rotten base plate structural wall with new wood.

What have we done in this house? 

-Insulation was repaired to keep the house with minimal energy loss properly.

-Super Sump Pump was installed to help with water issues in the crawlspace

-Mould killer was sprayed to kill affected areas that were showing signs of mold

We completed a full crawl space repair to address moisture, drainage, and structural concerns. A sump pump system with a battery backup was installed to manage groundwater and prevent flooding, even during power outages. The entire space was encapsulated and sealed with drainage matting to protect against seepage and improve durability. We removed debris and old insulation and treated all surfaces for mold. A dehumidifier was installed to control humidity, and new moisture-resistant insulation was added to boost energy efficiency. Structurally, we stabilized floor joists with a steel jack system and replaced a 10-foot section of rotten sill plate and rim joist, supporting the area with a steel I-beam and new framing. We also redirected exterior water flow to a catch basin to keep the area dry. The result is a clean, dry, and stable space ready to protect the home for years.

Addressing the rotten structure required replacing all damaged wood and redirecting the rain leader away from the house, as it was the main cause of the damage. Additionally, we replaced the old, malodorous fiberglass insulation with new silver airboard insulation.
