Before & After Photos

Before

The home had an old, worn out poly vapour barrier on the floor to separate the moist cold dirt from the living space. The older barrier was not functioning properly and allowed water and humidity to come through. Attempts were made to dry the area such as using house fans to move the air flow.

The insulation in the area was fiberglass batts in between the floor joists that contained high moisture content and would not stay in place. Fiberglass batts in the floor joists above is the wrong way to insulate a crawl space. Insulation needs to be where outside air will meet inside air.

After

Advanced Basement Systems installed the Clean Space encapsulation system which included ground encapsulation material up the sides of the exterior walls, spray foam insulation on the walls and finally a powerful dehumidification unit to keep the space dry.

If your crawl space is not treated properly it will affect your entire home. Give Advanced Basement Systems a call to remedy a bad dirt crawl space!

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.

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.
