"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."

"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"

"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!"

FAQs for spray foam insulation projects in Forest Grove, 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.
