"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."

"On day 1 they removed (sucked out) 3 levels (and three different types) of insulation. They were very neat and cleaned up afterward. They showed me pictures of the cleared attic. On day 2 they blew in new insulation, sealed an unused vent (which was causing a draft) and installed a new attic hatch (old one was broken, unsealed and not insulated causing a draft). Everything was done as agreed and in the timeline expected. They are also a partner with Energy Trust of Oregon which is a bonus."

"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."

"Absolutely great experience. I was looking to insulate and seal my garage from my bedroom. I have rough cut beams and 2x6 T&G decking that was not a standard distance apart (meaning there was no way to fit fiberglass insulation in at all, and then put in some kind of vapor barrier). Spray foam was the answer. Very professional, worked quickly and efficiently, cleaned up when they were finished, and even locked-up for me when they left (I had to go to work). I would highly recommend them for anything you need done!"

"Because our garage walls were already dry walled spray foam was not used but instead they blew in BIB insulation which is better for Rvalue. When Jennifer looked at our garage for the pre work bid, she made a couple of good recommendations which we took. Her written quote was detailed for each part of job. The installers showed up on time and were efficient and took care with our home and left garage very clean. Jennifer got us onto their work schedule very soon after she sent us her written cost for this job. Great company!"

"Ulises and his team were very efficient in their install of additional insulation in our attic. Not only that, but the price we got beat out the other two quotes! We were very happy with our hire of Ulises Pro Insulation."

"I had an extensive rat issue in the insulation under my house. The Crawlspace Crew came over the same day to give me a quote and inspect my crawlspace. They organized the entire job, including removing the insulation, setting up a new barrier, spray underneath my house with an antimicrobial chemical and reinstalling new insulation. They also orchestrated with a pest control company to come and set traps, and close up any holes that were ports of entry for the rats. They were extremely efficient at communicating back with me and Two to the timeline. Overall, I was very impressed with the Crawlspace Crew."

"2 Pro Construction insulated under my home and also installed new siding. Alan is accountable and easy to contact. There was one hiccup in the job but he was very fair and I was extremely happy with the end result. A few weeks after the job was completed I had a Pest Control Company come out, the man said he goes under many homes but has never seen a better job than 2 Pro did. He said was so clean and meticulously done that he would eat his lunch under there! Alan also sent me pictures of the underneath so that I could see their fabulous job. I would highly recommend 2 Pro Construction."

FAQs for spray foam insulation projects in Portland, OR

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
