How We Seal Basement Floor Cracks and Wall/Floor Joints
How We Seal Gravel Crawl Spaces
-
Sealing: Before we arrive the customer is informed that the owner is to relocate items 2 feet away from the walls in the unfinished basement and garage. This will allow us to seal all exposed wall/floor joints and floor cracks to achieve the best possible results and energy efficiency.

This home had insulation on the walls of the gravel crawl space. In this case, we will remove up to 12″ of the insulation to achieve a superior airtight seal of the plastic. Failure to do this step will reduce the efficiency of the system and increase the operating cost of the system. We will re-secure the insulation for an additional charge if needed.

We will seal the groundwater sump pit with a solid poly lid so that it is airtight. The lid is labeled with instructions for maintenance. The sump pit should be sealed airtight to trap radon and moisture under the slab so that it can be pulled out with the sub-slab ventilation system.
