Before & After Photos

The homeowner called Advanced Basement Systems because he wanted to use his crawl space for storage but had concerns about ongoing water flooding and high humidity.

The crawl space was partially done including full exterior wall insulation with vapour barrier and a rough concrete floor. Upon inspection it was clear the fiberglass insulation contained high levels of water and mould growth.

Advanced Basement Systems removed all the insulation and vapour barrier before starting the repair process. A new sump pump system and drainage was added to reduce the water entering the home. Encapsulation of the crawl space was next using Clean Space and spray foam to seal the area and provide the needed insulation to keep the crawl space conditioned. It is important to note, spray foam needs to be include in the header area (above the foundation wall), but not in the floor joist and subfloor area. A thermal barrier was required over the spray foam because the furnace was located in the crawl space. This was achieved with the use of paint-based spray called DC315. The final step of the project was to install an efficient, high-performance dehumidifier that will dry the space and keep it that way in the future.

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.

Before

The owners of the home wanted to update the crawl space to help improve the comfort in the living areas of the home. The work included full encapsulation of the crawl space and spray foam insulation along all exterior walls.

Building code requires a thermal barrier over spray foam insulation in any interior space of a building that is heated or used as living space. This is a fire safety requirement to protect against ignition and heat spread. Areas like crawl spaces, attics, and rim joists often have exceptions, but a thermal barrier is required if these spaces are used for storage or if they have air ducts connected to the living space. 

After

Advanced Basement Systems applied a paint based coating on all exposed spray foam used to insulate the crawl space. The coating is specially designed to meet the code requirements for fire safety!

Call Advanced Basement Systems if you have exposed spray foam insulation in your home.

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.
