"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."

"This took a couple years to fully complete as I have a Hip (Jack)-roof. The structure blocked off the last 4 feet from the end of the house, where the secondary roof takes over. Unfortunately, voids were inevitable because of all the obstructive joists etc. The next winter this was evident as the snow had melted over the areas that had no insulation. I took pictures, and Ryan sent a crew back to try again. I was happy, but the next winter showed the same voids. A week or so ago, I took out eve boards and found the void(s). Insulated it myself, but realized other end of roof would have the same issue. Called Ryan and he agreed (2 years later mind you) to fill it in for me. Then I drilled a small hole and put a bore-camera in and discovered all center bats had voids of 2 feet or so the length of the house. I scrambled (the night before appointment) and used a hole saw and cut out 7 additional holes through the 2x4 blocks. Too late to call that night and inform them of my new discoveries, I called (almost) first thing next morning to explain the job had gotten a little bigger than a 4x4 foot area. Once he understood the scope of project, Ryan said (as my doorbell was ringing) that they would do whatever needed to be done; just let them know, and call him with any issues. The workers figured out ways to get into the small openings with their hoses and made it work. Didn't argue, very respectful and stuck to it. I couldn't have been more relieved. Thank you for helping me with this issue of 30 years! I just knew my house was cold in winter, and hot in summer. I missed a chance to inspect this area when a roofing job would have allowed me to remove plywood and insulate it then, (as the original builder should have done). This was a "Good 'Cents' Home" from the '70s (PGE program) when insulation was being used to save energy. They just "missed a spot". Thanks everyone. Now my home finally makes 'Cents'!"

"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"

"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

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, 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, 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?

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, 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.
