A homeowner in Knik-Fairview reached out to us about persistent ice dams forming along their roofline and high heating bills during winter. Our team inspected the attic and found minimal, settled fiberglass insulation with extensive air leakage through the top plates and recessed lighting. We applied closed-cell spray foam to seal all penetrations and then added open-cell spray foam across the attic floor to bring the R-value up to current standards. The homeowner reported a noticeable reduction in heating costs the very first month and has not dealt with ice dams since.
