We completed a thorough attic insulation and air sealing project for this residence in Canonsburg. Our team began by protecting the home's interior with drop cloths before identifying and sealing various air bypasses around electrical junction boxes, plumbing vents, and flue pipes. We also addressed moisture signals on the roof sheathing to ensure a dry, stable environment for the new materials. After completing the air sealing phase, we installed a thick layer of blown-in cellulose insulation to significantly improve the home's thermal performance. We also reinforced the attic access hatch and ensured all penetrations were properly blocked with rigid foam and sealants. This comprehensive upgrade creates a more consistent indoor climate and reduces the workload on the HVAC system year-round.
