"JR Insulation is a great company!! They did everything from start to finish as promised, on time, polite, clean, and on budget. I can't recommend them enough. They also fixed a problem that I created in my own ignorance for free just to make me even happier. I told them it wasn't necessary but they insisted. JR's pricing was the absolute best for everything they did. Not the lowest bid but the lowest price to value, which in my opinion is the lowest bid. I would use they again, in fact, I would not use any other company for insulation or dry wall. Brian"

"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."

"Did a great job of installing insulation and drywall however, they cracked a wall when installing the drywall, they hammered rather than screw it into the studs. Now I must repair the cracked wall. Somehow my compact florescent light also disappeared from the laundry room . They also initially wanted to put the R-30 insulation on top of the R-11 that was already in the ceiling. When compressed the insulation would have lost some of its insulating capabilities so I had to tell them not to do that. Seems they should have known this."

Insulation questions, answered by experts

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?

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?

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.
