Creating a Healthier, More Comfortable Crawl Space

For this project, we turned the crawl space into a clean, dry, and healthier area. We started by installing drainage matting on the floor and partway up the walls to protect against ground moisture and provide a durable surface for storage. We then treated all wood and organic surfaces to prevent mould growth and gave the space a thorough cleaning wiping down ducts, removing spider webs, and clearing loose debris.

To improve comfort and energy efficiency, we added rigid insulation to the walls and rim joists, sealing all seams and gaps to stop air leaks. Finally, we fully encapsulated the crawl space with a heavy-duty liner, fastening and sealing it to the walls, footings, and piers. This creates a sealed barrier that helps keep the area dry, insulated, and protected from moisture and energy loss.
