What insulation work usually includes
Assess current attic performance
We inspect the attic to see whether the current insulation is helping, failing, or hiding a larger restoration issue.
Remove damaged or contaminated material
If the existing insulation has been compromised, we remove it cleanly before a new installation goes in.
Install to a higher standard
Fresh insulation should cover properly, perform properly, and leave the attic in better condition than we found it.
