"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!"

"We had a small job to remove/replace insulation that may have been soiled in our attic from a squirrel that got up there years ago. It was mentioned in our home inspection. After going up to take a look, Sean explained he didn’t see any soiled insulation but there was a small area that had been moved away from the corner and it was effectively empty. It was really too small a job though to warrant them coming out to blow stuff in so he recommended just taking a leaf blower up there to redistribute it evenly. Brilliant idea! He also graciously took a look at our crawl space and identified some areas we should address but ones we could do on our own. He was great to talk to and very helpful and reasonable. So nice in these days of everyone trying to upsell everything. If and when we need insulation work, we’ll be calling Dr. Energy Saver! Thanks so much, Sean Becker!"

"Ulises was able to get in quickly and get the job completed insulating my shop ceiling trusses with batt insulation. I would have preferred white FSK instead of clear plastic but it would have put me way over budget Overall they did a good job"

"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."

"Westside Drywall was the only firm willing to do what I requested, which was to repair and not replace under-floor insulation. As a result, their price was much lower. An added bonus was that they could schedule the job in a few days instead of a few weeks or months."

Customers say: True professional

"They did a very thorough crawl space clean up and detailed and well secured installation of the vapor barrier . They were honest, and efficient with positive energy. The issues are with communications from the office. They could be more professional, timely and thorough."

Insulation FAQs, answered by experts

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.

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?

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?

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.
