Crawl Space Repair Before & After Photos

Although this crawl space was very clean with little evidence of pests and no standing water, the unencapsulated space still affected the home above by what is known as the stock effect. https://www.advancedbasementsystems.net/home-mold/stack-effect.html Resulting in problems such as:

• Damp, musty smells

• Higher than healthy levels of humidity

• Less-than-desirable heating and cooling costs

The best method to remedy these problems is by completely sealing off the crawl space from the outside environment! Our Advanced Basement Systems team was happy to help these Chatham homeowners.

Problem: These home owners contacted Advanced Basement Systems to improve their crawl space environment for the benefit and health of the entire home. The access area was unlevel, often wet and not properly enclosed.

Solution: With crawl space accesses, there are two important points to remember:

1. The access needs to be accessible.
2. The access needs to be sealed so the outside fluctuations in temperature and humidity do not affect the improved crawl space environment.

Our team did a great job improving this access area for ease of entry and to seal off the outside environment from the crawl space.

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.

Problem: The homeowner required improved access to their crawl space.

Solution: We installed a steel window well, as part of the crawl space access is below grade and added an EverLast crawl space access door which seals tightly for an ideal crawl space environment.

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.
