"the quality of work was high. i am satisfied with the result. i did, however, have a lot more clean up after they left, than i expected. they may consider using tarps on the ground around a house before applying the foam. there are pieces of foam all throughout my landscaping, lawn, and around the house. also, a little more professionalism would be nice. the workers, without asking, decimated my blueberries, which is disturbing as i rely on the food i grow."

"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."

"Staff was attentive and friendly. The men who removed our messy insulation under the house did so with a smile then stated "We get to spray in superior insulation to make your homer more comfortable". Work was coordinated with Scott Law of All Natural Pest Elimination who also speaks highly of Josh Lowe's Dr. Energy Saver. - Shannon"

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.
