Thank you, Smart Choice. Our prehistoric roof dealt with leaks for many years anf expensive repairs never quite worked. Always chasing leaks, finally we have no leaks and Not only that- but we also barely touched the thermostat since it was put in last summer.

Had leaks in my commercial building, decided to give a spray foam roof a shot versus a whole replacement. The company was professional, the roof looks good, and it came with a warranty

The team at NW Weatherization was great from start to finish. They came out and pre planned exactly what we needed and even assisted navigating the state rebates. Great customer service

Nicholas Russi★★★★★a month ago

From start to finish, working with Northwest was really easy and enjoyable. Ryan was great about explaining what was needed in an easy to understand way. Also very knowledgeable about rebates available from the various energy companies. The crew that came was very efficient, cleaned up after themselves and made a great first impression. All around good experience for us.

Elizabeth Kirkpatrick★★★★★a month ago

Had insulation added to my attic and put it the floor. Arrived as scheduled, were quick and efficient. Had some slight confusion over one detail, but it was easily clarified with one phone call so things could still move forward smoothly. And when done, they helps with completing the forms for the energy rebates which was really, really appreciated.

This review is long overdue, but I have used Valley Insulation twice and at two different houses, and both times the service was exceptional! Cassidy especially handled a very frustrating rescheduling situation very professionally. Their work is of the highest quality, and the team works efficiently. Recently, I had my crawl space inspected, and after almost 3 years, the report was exemplary and they only mentioned dust. This just proves the quality of the work done by Valley Insulation! I highly recommend this company!

C S★★★★★7 months ago

I recently had the pleasure of working with Valley Insulation in Salem, Oregon, and I couldn’t be happier with the experience. From the very beginning, their team was professional, punctual, and highly knowledgeable. They carefully evaluated my home's insulation needs and offered thoughtful, customized recommendations. The installation process was smooth and efficient, with the crew maintaining a clean and organized work environment throughout. I noticed an immediate improvement in my home's comfort, especially with better temperature control. The work was done right the first time, with impressive attention to detail. I highly recommend Valley Insulation to anyone in need of reliable, top-quality insulation services. Their exceptional customer service and expertise truly make them stand out!

Linda Smith★★★★★4 months ago

Although I ended up using a company from my local area, I must say that Cassidy was very generous in giving insight and recommendations for other aspects of my wet crawl space resolution, which was the result of a broken pipe. I am an elderly widow who had no idea what to do or who to call. He was a blessing in giving me direction and suggestions. By reading the other reviews I am certain that they do very good work also.

The work was done very professionally and efficiently. Brandon and his crew were very respectful of our property and left no messes or trash. The crawl space was absolutely amazing when they were done, way nicer than we were expecting. We are VERY happy with the outcome and we can't thank them enough for the care and quality they put into our home!

This review is overdue... We had Klaus Roofing replace our roof in 2023 in Eugene. The team was very accommodating. I've felt screwed by other local companies for other projects in the past with poor work quality or inconsistencies, so Klaus probably was tired of me checking on them pretty regularly. Good news is that we're satisfied with our roof and we've had zero leaks as far as we've noticed! The project manager Johnathan and the rest of the Latino team were professional and friendly. Overall, it was more than other quotes at the time but the interest and warranty convinced us. I'd recommend them.

Lynn McMurphy★★★★★2 months ago

Thomas was extraordinarily helpful explaining everything. Instead of a hard sell like other estimates I had done, he gave me an education in how to build a roof. He was one of the few that did a thorough inspection of my attic and went out of his way to help with scheduling. I appreciate everything he did and would highly recommend this company.

realbasso★★★★★a month ago

We had Christopher from Klause Roofing at our place for an estimate. This was a good experience. He is a warm, friendly, informed and professional person. No hard sell. We hit it off quickly. Christopher has been attentive with follow up connection. The job is schedule for sooner than we expected. Though the work has not yet started, we are resting easy and feeling as though we are in good hands. Thank you, Chris

I helped out a friend one day that had Capital City spray foam out to her home to spray insulation into the attic. Capital City spray foam was very helpful and efficient. I was very impressed with the work. I definitely would hire them if I needed insulation sprayed into my personal home.

Xander Hall★★★★★2 years ago

We just had our deck rebuilt by Salem deck and fence pros and we couldn't be happier. From initial contact with Mike and his crew we have been happy. Mike was always communicative with us about when they would start and progress on the deck itself. The end result is amazing and we are extremely happy.

Taylor Bartell★★★★★2 years ago

Salem Deck and Fence finished replacing our rather large deck last week in south Salem, and we couldn’t be happier. Mike and Ryan showed up when they said they would and after taking some measurements and choosing some samples they had a quote to us in just a few minutes. Their easy going demeanors and professionalism is what helped sell us on choosing them. They started the deck when they said they would, kept the work area clean and finished right on time. It was a pleasure having them and the crew out here, I know our dogs will miss them too. I wouldn’t hesitate to hire them again in the future for any deck or fence needs.

Frequently Asked Questions — Spray Foam Insulation in Salem

These are the questions Salem homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 35% typical energy savings. Compare the 9 verified Salem contractors above for exact quotes.

How much can spray foam insulation save on heating and cooling bills in Salem?▼
Homeowners in mixed climates like Salem, OR typically see 20–30% reductions in total energy costs after spray foam installation. The savings come from both reduced heating in winter and reduced cooling in summer. The exact savings depend on your home's current insulation, size, and local energy rates, but most homeowners recoup the investment within 3–6 years.
Is spray foam better than fiberglass insulation for homes in Salem?▼
For most homes in Salem, OR, spray foam outperforms fiberglass significantly. Fiberglass batts insulate but do not air seal — meaning conditioned air still escapes through gaps. Spray foam both insulates and creates an airtight seal, addressing the root cause of energy loss. While spray foam costs more upfront, the performance difference in mixed climates makes it the better long-term investment for most homeowners.
Is spray foam insulation worth the cost?▼
For most homeowners, yes. Spray foam creates an air-tight seal that traditional insulation cannot match, reducing energy bills by 15–35% annually. It also adds structural rigidity, acts as a moisture and vapor barrier, reduces outside noise, and can increase home resale value. The higher upfront cost compared to fiberglass is typically recovered within 3–7 years. One important note: because spray foam creates a very tight building envelope, proper mechanical ventilation is important to maintain healthy indoor air quality and prevent interior moisture buildup. This is typically handled by an Energy Recovery Ventilator (ERV) — a system that brings fresh outside air in while pushing stale air out, recovering the energy from the outgoing air so you don't waste what you paid to heat or cool — or a Heat Recovery Ventilator (HRV), which works similarly but is optimized for cold climates. A qualified contractor will assess whether your home needs ventilation upgrades as part of the installation.
How much does spray foam insulation cost in Salem, OR?▼
In Salem, OR and the surrounding area, spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your home's specifics. Open-cell foam runs $0.44–$0.65 per board foot, while closed-cell foam costs $1.00–$2.00 per board foot. A typical 2,000 sq ft home attic in Salem costs $2,000–$6,000. Most Salem homeowners recoup this investment within 3–7 years through energy savings of 15–35% annually.
What is the difference between open-cell and closed-cell spray foam?▼
Open-cell spray foam is softer, less dense, and less expensive. It expands significantly and is ideal for interior walls, attics, and soundproofing. Closed-cell spray foam is denser, stronger, and provides a moisture barrier — making it better for exterior applications, crawl spaces, and areas prone to flooding or humidity. Closed-cell also has a higher R-value per inch (R-6 to R-7 vs R-3.5 to R-4 for open-cell). One key difference: open-cell foam allows some vapor movement, while closed-cell acts as a vapor barrier — an important consideration for your home's ventilation needs.
How long does spray foam insulation last?▼
Spray foam insulation is one of the most durable insulation options available, with a lifespan of 80+ years when properly installed. Unlike fiberglass batting which can sag and settle over time, spray foam maintains its shape and insulating properties indefinitely. It will typically outlast the building it is installed in.
How do I find a qualified spray foam insulation contractor in Salem, OR?▼
When searching for a spray foam contractor in Salem, OR, look for ones who are licensed, insured, and have verifiable reviews. Spray foam requires specialized equipment and training — improper installation can cause off-gassing, adhesion failure, or fire hazards. Ask for references, verify their insurance, and get at least 2–3 quotes. A qualified Salem contractor will also assess your home's ventilation needs — a tightly sealed spray foam installation requires adequate mechanical ventilation to prevent moisture and indoor air quality issues. FoamMatch pre-screens all listed contractors in Salem for licensing and insurance so you can compare verified professionals in your area.
How long does spray foam installation take?▼
Most residential spray foam jobs take 1–2 days depending on the size of the area. A standard attic takes 4–8 hours. After spraying, the foam cures within 24 hours, though most contractors recommend waiting 24–72 hours before occupying the space due to off-gassing during the curing process.
Does spray foam insulation need to be replaced?▼
No — spray foam insulation does not need to be replaced under normal circumstances. Unlike fiberglass insulation which degrades over time, spray foam maintains its R-value and air sealing properties for the life of the building. The only reasons to remove or replace spray foam are water damage, renovation work, or improper original installation.
