Restore comfort. Boost efficiency. Protect your investment.
Our insulation and air sealing services are tailored for Portland’s unique housing stock, especially the thousands of pre-1980 homes that aren’t built to modern energy standards. While most contractors stop at insulation, we go further. Why? Because insulation without air sealing is like wearing a warm coat full of holes. Air sealing is what transforms an insulated home into a high-performing one—eliminating drafts, preventing moisture problems, and making your heating and cooling systems truly effective.
At Resilient Retrofits, we specialize in comprehensive weatherization upgrades that combine targeted insulation with expert air sealing to deliver lasting comfort, lower bills, and a healthier indoor environment.
Why Insulation and Air Sealing Matter
Portland is known for its charm—and its chill. From cozy bungalows and hundred-plus-year-old foursquares, to mid-century rentals, our city’s older homes are rich in character but often lacking in comfort. Drafty rooms, high utility bills, and inconsistent indoor temperatures aren’t just annoyances; they’re symptoms of deeper inefficiencies in the building envelope. At Resilient Retrofits, we’re here to change that.
Insulation and air sealing work hand-in-hand to reduce heat loss in the winter and keep cool air inside during the summer. In an older Portland home, it’s common to find little to no insulation in walls or floors, under-insulated attics, and countless gaps where outside air slips in. These leaks add up to discomfort, to higher utility bills, and to overworked heating systems.
A well-sealed, well-insulated home performs better in every season:
- In winter: It stays warmer without relying on constant furnace use.
- In summer: It keeps the heat out and helps your cooling system run efficiently.
- Year-round: It reduces noise, filters out outdoor pollutants, and prevents moisture problems that lead to mold or rot.
For homeowners and landlords alike, upgrading insulation and sealing air leaks is one of the most impactful and cost-effective energy improvements you can make.
Is Your Portland Home In Need of an Upgrade?
Over 60% of Portland homes were built before 1980, long before modern energy codes required comprehensive insulation. A city analysis estimates that more than 137,000 housing units remain under-insulated and unweatherized, especially older rentals that may not have been remodeled in decades.
If you’re the steward of a classic Craftsman or a post-war rental, chances are your home could benefit from targeted upgrades. Resilient Retrofits takes a science-based approach: we begin with diagnostics like blower door tests and infrared imaging to locate the exact sources of heat loss and air infiltration. Then we develop a custom plan to insulate attics, walls, floors, and crawlspaces—and seal the envelope for maximum performance.
