Before & After Photos

The home was built over 60 years ago with block foundation walls, a dirt crawl space floor and poor insulation. The main floors are cold in the winter and the musty smell is strong throughout the house.

Advanced Basement was called for a crawl space inspection. The best option was a full CleanSpace encapsulation system, 3" of spray foam insulation on the exterior walls and header, a sump pump system to drain the water and a high-quality dehumidifier to dry out the space. The home will now be dry all year long, the musty smell from the crawl space will go away and the first-floor floors will be warmer.

Crawl space construction has changed over the years. Previously it was considered important to allow venting into the space from the exterior, insulation between the floor joists and a gravel base for drainage should water seep in.

New building techniques have shown a completely closed area with insulation along the walls and into the header provides a much better result. Humidity does not build up under the first floor and the area will stay warmer allowing the heating systems to work less.

In the case shown, the crawl space was clean and clutter-free but was not complete. It had outside vents into the area, rigid foam insulation along the exterior walls- but not into the headers- and a gravel base.

Advanced Basement Systems was called to update the area and improve the conditions. Encapsulation was completed with Clean Space, closed-cell spray foam was installed for insulation including into the headers, and the vents closed off.

The home now has a warm dry space which will improve the living areas above. Advanced Basement Systems provides home owners in London, Chatham, Windsor, Sarnia and surrounding areas complete free inspections to update outdated and troublesome crawl spaces.

Challenge: Access doors or open vents in a crawl space is one of the areas where the outside environment enters and affects an entire home. 

Solution: A sealed crawl space access is one of the many things we do when encapsulating a crawl space. We also installed a well for improved access and drainage.

Challenge: This crawl space could be described as “high and dry”... but the dirt floor and lack of insulation on the exterior walls made the home’s floor cold during the winter months. 

Solution: We completely sealed the crawl space from the outside environment, and added spray foam insulation. Spray foam offers a  high R-value, sealing air leaks and also serving as a moisture barrier.

Before:

The home was built with a 5’ crawl space using block foundation and a dirt floor. It was tidy and well built, but still humid for most of the year. Over time the musty smell began to travel through the entire house.

After

Advanced Basement Systems installed their Clean Space encapsulation system and used spray foam insulation on the walls. The encapsulation will provide a vapour barrier from the dirt below and the spray foam will insulation will seal the system to not allow the air to pass through. The spray foam will add much needed insulation to the space and help maintain comfortable temperatures all year long.

If your crawl space has exposed dirt floors, give Advanced Basement Systems a call for an inspection!
