Before & After Photos

Challenge: When it comes to repairing crawl spaces, people usually reach out to us for one or a combination of the following reasons: 

• Musty, funky smells

• Excessive dampness or humidity in the home 

• High heating and cooling costs

• Structural problems (such as sloping floors)

• Cold floors

These homeowners in Port Lambton did not want to face another winter walking on icy cold floors in their home. The previous owners attempted to create a more efficient and comfortable home by installing rigid wall insulation to the exterior foundation walls and stuffing fibreglass insulation into the floor joists above… but these efforts are completely ineffective in an unsealed crawl space. 

Solution: Our team encapsulated the crawl space, completely sealing it off from the outside environment. We then applied spray foam insulation to the exterior walls. The Canadian product we use is Polarfoam7300, it seals air leaks, preventing intrusion and providing insulation. It adheres permanently to all materials, is waterproof and won’t degrade, compress, or lose its R-value as other insulation types can.

Problem: These Wallaceburg homeowners were experiencing problems in their home, such as high humidity, damp smells and even mould growth as a result of their excessively wet dirt crawl space. 

The wet and unhealthy air is drawn upwards into the home from the dirt crawl space through tiny cracks - and although air molecules are microscopic, it caused huge problems in the home above. 

Solution: We’re so pleased these homeowners contacted us to help them. During the inspection process, we noted the crawl space area lies low and is naturally prone to water entering. To remedy this, we installed drainage pipe, a powerful sump pump, specifically designed for crawl spaces to remove this water and a powerful, yet energy-efficient, near-maintenance-free dehumidifier to help further control the moisture in the space. We then completely sealed the crawl space with our CleanSpace liner and added spray foam insulation. 

All of these products work together to ensure the water is kept away and the humidity level acceptable in the crawl space. 

Now the homeowners can better enjoy their home! 

Problem:  Even with a nice layer of clean gravel, this crawl space still has the effects of a typical unsealed crawl space.

Humid air and water vapour enter a home through the porous foundation, crawl space vents and up from the dirt floor of the crawl space; resulting in a damp crawl space, musty odors and an unhealthy environment throughout the entire home.

Solution: Wow – what a difference!

Our team installed the CleanSpace® Crawl Space Vapor Barrier: a super durable 20-mil poly-reinforced liner. Now this clean and dry crawl space is a usable storage area and a healthier environment!

Problem: This crawl space was very humid and full of condensation. Also as you can see it flooded.

Solution: We installed sufficient drainage with a sump pump that discharges outside. The Clean Space vapor barrier was installed to isolate the home from the earth, making it a dry & healthy space.

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.
