Insulation can last for many years, but it does not always perform at peak efficiency indefinitely. Moisture damage, pest infestations, settling, contamination, and age can all reduce effectiveness.
Common indicators include increasing utility bills, inconsistent room temperatures, poor indoor air quality, and visible deterioration in attic spaces.
Replacing old insulation can restore energy efficiency, improve indoor comfort, and help reduce long-term operating costs. A professional inspection can determine whether replacement or supplemental insulation is the best solution for your home.
