Crawlspace Sealing in Richmond Virginia

Crawl space sealing is a great way to save money and make your home a safer cleaner environment for you and your family. Unsealed crawl spaces are major air leak locations. Significant amounts of conditioned air is lost to the crawl due to hole penetrations where all wiring, plumbing and HVAC materials go into the crawl space and are left unsealed. When you have crawl space leaks the home becomes drafty and uncomfortable. By sealing a crawl space the U.S Energy Star program estimates the saving of 20% on energy bills. Second, to the attic, the crawl is one of the largest opportunities to save energy in your home. By sealing and insulating your crawl you can prevent cold floors and reduce drafts from below to keep your home comfortable. It also will prevent and kill any mold that has or will form from the moisture that was present in the crawl.

How to complete a Klosed Krawl:

  • Inspect the crawl for major issues meaning gaps and holes in foundation.
  • Remove all insulation from floors and remove all plastic.
  • Level the ground as much as possible and rake out any trash and debris to allow for a smooth crawl space floor.
  • Lay down a 6mm poly liner. This is thicker than most companies use to ensure it will last.
  • Run liner up support columns and tact to walls.
  • Then seal liner to columns and walls with waterproof tape. We also seal any liner connections together to make a single sheet.
  • Seal all penetrations meaning wiring plumbing and HVAC holes with a 2 part foam.
  • Seal foundation vents with foam board and spray foam.
  • Then add insulation to exterior walls to help prevent heat loss/gain in winter or summer.
  • Seal the insulation to the walls with foam to ensure a tight seal.
  • When we are done this is a sealed and clean environment. So clean in fact that we put up “remove your shoes” signs to prevent bringing in dirt to the clean environment.

How do I know I need this?

  • Look for gaps around rim joints and under the still plate
  • Along the gap between still plate and the foundation
