"I had an emergency and JR Insulation Drywall did an amazing job. I had just sold my house, and in the process of moving, the movers broke a pipe that had to be repaired behind a wall on the day we gave possession to the new owners. I called JR Insulation Drywall and they were there the same day I called and did a wonderful job of the repair. Responsive, quality, and for a great price. Would definitely hire again if I needed help. I so appreciated their help in a stressful time for me."

"The guys at NW Weatherization did an excellent job installing additional insulation in my attic and crawlspace. They also reattached the exhaust fan boot. I can tell that the added insulation is helping keep my home warmer since the furnace doesn't come on as often and run as long. Thank you Ryan and everyone at NW Weatherization!"

"Juan of Timberland Insulation did an outstanding job. We had critters get into our crawl space where they ran amok all through our insulation. The old insulation had to be removed and new insulation installed. The crew at Timberland out performed my expectations. I would highly recommend them."

"Would recommend to anyone! Ulises Pro Insulation, LLC were great advocates for their customer's best interest. My attic space was under-insulated. They did a careful inspection of the space, and showed me photos of their findings. They were honest about there being no urgent issue, and about what might be limitations of working in such a tight space. Nonetheless, they were happy to attempt the service and were able to maximize the space's energy efficiency. They were fast to give an estimate, fast to schedule and complete the job, and they left the workspace spotless."

"The Oregon Energy Trust guy was here at the same time, and said the crews had to do substantial work in the attic to repair fan ducts. From all the sawing and hammering I heard, it sounds like quite a bit got fixed up there. It was nice that the Energy Trust guy knew insulation jobs so well and provided reassurances that everything he saw was being done correctly. I'm not going to crawl under the house to see the new vapor barrier and new pipe insulation, have to count on their reputation and good word for that part of the job."

Insulation questions, answered by experts

In Portland, you’ll find several contractor types for insulation service, including dedicated insulation specialists, full-service energy efficiency contractors, attic insulation experts, spray foam insulation professionals, and general contractors for larger remodels. Some HVAC contractors also offer insulation upgrades. It’s important to choose a contractor experienced with Portland’s moisture challenges and knowledgeable about local energy efficiency requirements.

Helpful?

Pairing insulation service with upgrades like air sealing, attic ventilation, or HVAC improvements in Portland is highly effective. Coordinating these projects can reduce labor time and maximize home energy efficiency. Completing multiple upgrades together may also help you qualify for local energy efficiency rebates, making your home more comfortable and reducing drafts, especially during Portland’s damp winters.

Helpful?

Due to Portland’s damp climate, insulation service projects benefit from annual inspections for moisture intrusion, pest activity, and ventilation blockages. Homeowners should check attic insulation for settling, ensure vapor barriers remain intact, and look for signs of mold or mildew. Spray foam insulation is low-maintenance but should still be inspected periodically, especially after heavy rainfall or seasonal changes.

Helpful?

In Portland, attic insulation service typically takes one to two days, while wall or crawl space insulation may require up to three days. Whole-home insulation projects, especially those including air sealing, can take about a week. Weather conditions and permit approval from the city can sometimes extend timelines, so planning ahead—particularly in the busy summer months—is recommended.

Helpful?

In Portland, frequent rain and fluctuating temperatures make moisture control a top priority for insulation service projects. Choosing insulation types like closed-cell spray foam or rigid foam board helps resist dampness and prevent mold. Installers often recommend vapor barriers and attic insulation upgrades to combat condensation. Scheduling work in late spring or early fall can minimize weather-related delays and ensure optimal installation conditions.
