Settled attic insulation leaving the top plate exposed
Why it happens here
Blown insulation loses depth over 10 to 15 years, especially in attics that get hot in summer. Once it drops below the top plate, cold air pours in from the eaves. Homes built before 1990 in Pleasant Grove West are the most affected.
Our approach
We measure the depth, air-seal the top plates and penetrations, then blow fresh cellulose to the correct R-value. Sealing first is what makes the new insulation work.
