Rim Joist Sealing Before
Rim Joist Sealing After

Rim Joist Sealing

Sealing rim joists can help solve a number of comfort issues. Unsealed rim joists allow excess cold air to enter the home. Often cold basements, cold floors, inconsistent room temperatures, and high energy costs are affected by air infiltration via the rim joists as they are often the second leakiest part of the home after the attic.

Green Bay, WI - Removing FIberglass Batts and Air Sealing Rim Joists

This homeowner had old fiberglass batts in the rim joists. They were dirty, extremely compacted and not functioning. We removed them and used spray foam to air seal and insulate the rim joist area.

Chimney Chase Before
Chimney Chase After

Chimney Chase

Almost all chimneys have an air gap around them per building code.  Often these chases extend from the basement all the way up to the attic and are a highway of sorts for warm, conditioned air to escape.  Metal and fireproof caulk are used to seal up these huge heat loss areas in the air sealing process.
