"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."

"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!"

"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"

"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."

"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!"

"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."

FAQs for spray foam insulation projects in Banks, 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.
