I had an excellent experience working with The Spray Foam Company from start to finish. Jesse was fantastic — he met with me on site the day after our first call to review the scope of work and answer all my questions. Christine was also great to work with, keeping everything organized and clear over the phone as we discussed the job details and cost. On install day, Gio did an outstanding job. He took great care to protect the house by masking off all the necessary areas before completing a very professional installation. The quality of the work really shows — the home already feels noticeably more comfortable, and I’m looking forward to seeing the difference in my energy bills. They even helped me apply for Energy Trust of Oregon incentives, which offset part of the project cost. Overall, it was a great experience — great people, great work, and great results. Highly recommend The Spray Foam Company!

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

monica smith★★★★★a year ago

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.

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.

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.

denise parazoo★★★★★a week ago

Thomas came to my home to give me a roofing quote. I found him to be knowledgeable, energetic, and helpful. He came up with several options that will work for now, and a pretty reasonable quote for a complete replacement. The financial info was helpful although I plan to use my credit union. I like that he showed me the actual materials to be used on my roof and explained the process carefully. As a woman, sometimes we can get talked down to. I did not feel like just a 'dumb woman' as he treated me as an equal and informed consumer. I appreciate his honest assessment that my roof will not need to be replaced yet and will get someone to fix the vents that appear to be leaking. He could have "sold up" and talked me into a new roof, but he knows a widow on social security struggles. Or just replace the part in worst shape and the rest in stages as I can afford. Thomas communicated well with me and offered to help me negotiate with the other salesman and compare the different products and services which can be overwhelming. The brochure offered is very comprehensive and shows the level of the company is superior.

John DeRoin★★★★★7 months ago

Very good experience with Klaus Roofing. Chris and Aidan are great! Very clean and friendly crew. They cleaned up after themselves. Chris walked us through the process and supported us throughout. We love our high quality roof. We had 24 solar panels and they took them down and put them up. They restarted the system for us too. Aiden ran a tight ship and worked hard in a timely manner. Very comfortable and stress free process. Highly recommend Klaus Roofing. They are doing our insulation so stay tuned for next review. I'm sure it will be another 5 stars.

Kate Simpson★★★★★a month ago

We just purchased a home and needed an estimate on a roof repair. Sean was on time, courteous and very knowledgeable, saw things our inspector never caught. We appreciated his thoroughness, suggestions and honesty. Great conversation and didn’t mind us tagging along and asking questions. We would highly recommend Klaus Roofing.

I had an excellent experience with All West Coast Insulation. The Job was a new crawlspace removal and instrallation of insulation bats, water pipe and heat insulation wraps and vapor barrier. The crew was prompt, professional, and kept the work site very clean throughout the project. The workers arrived on time each day, and the bid was fair and reasonable. Noe, the owner, was always available to answer my questions and listened carefully to my concerns about the new crawlspace renovation. The team, with Rubin leading the work, made sure everything went smoothly from start to finish. I truly appreciate their attention to detail and the respectful way they communicated with me. I would gladly recommend them to anyone in need of quality insulation, crawlspace work, or drywall services. If you want, I can also make a slightly shorter version so it shows in full without users having to click “read more” on Yelp or Google. That can help more people see your recommendation right away.

Bill Carver★★★★★2 years ago

What an awesome job that All West Coast Insulation did in our crawl space. New insulation under house floor, tightening up heating duct work where needed and sealing and wrapping the ducts and water pipes. The crew was excellent and took great care to control dust and cleaned up after their job. Noe Ramos, owner, was easy to work with and very responsive to questions and pricing was very fair. If you need a company you can trust to do the work right, All West Coast Insulation is the place for 5 Star performance. Bill & Sue Tigard

Jennifer LeVasseur★★★★★2 years ago

All West Coast just left after applying spray foam to our garages vaulted ceiling and walls (hang out space renovation) and they did AMAZING!!! Noe (owner) is incredibly easy to work with; the bidding, scheduling, etc was fair and timely and the products he uses are top notch (I was worried about the fumes and lingering odor). His is crew showed up on time and ready to work (with Noe being here at the start and looking everything over at the end, as well as calling to check in throughout the day. Impressive!). They were friendly and efficient. They took the extra time to pristinely wrap the exposed trusses, windows and cover the floor. When they were finished, the garage was cleaner than when they started! The entire garage was dust free and not a speck of overspray on anything! And NO stink :)) I am absolutely thrilled with their work and am looking forward to getting our home done next! I would give more stars if possible. They went above and beyond, surpassing my expectations… and that is not easy :))

At first we were hesitant to use this company to have insulation blown into our walls due to some of the negative reviews. But, when we saw the reason for the negative reviews were due to communication issues and not the work done, we decided to give them a go. We couldn’t be more happy with that decision. The whole experience was the best you could expect. Jennifer was very knowledgeable and the most helpful out of the 4 companies we received bids from. She asked many questions about our home that others didn’t and offered solutions to help with the problem areas. The crew that did the install were fantastic. They were friendly and hardworking, plus very respectful of our home and landscaping. And, they cleaned the work area so you could hardly tell they were there. We will definitely be recommending them to others!

Laura Hertner★★★★★a year ago

Performance Insulation and Energy Services went above and beyond. Such a great value for the package. From the onsite estimating with Nelsin, to sucking out the old insulation of our entire 4k sqft attic, prep work, adding R42 back, assistance with Energy Trust rebate, our experience was 5 Stars. This is our 2nd home we've worked with Performance on and we highly recommend them. Fast and efficient!

Ken Newman★★★★★5 years ago

What a great experience we had from a residential service provider. Performance Insulation recently added insulation to our attic space. Samuel arrived on time, was professional and courteous to look at the job. He provided a quote while onsite. Other companies took up to over 10 days just to provide a simple quote.... that was disappointing. Performance installers Jorge and Jose arrived a few days later as scheduled and on time (even a bit early)! They were professional, clean and respectful of our home as they did their jobs. They cleaned up and completed the job within the estimated time. It is refreshing to see great customer service still exists. It was definitely a great experience and I would recommend and use Performance Insulation again. They were great from start to finish. Thanks Samuel, Jorge and Jose.

They did a residential insulation project on a remodel that was already furnished, etc. The crew was exceptionally neat, clean, did a very careful job, texted when finished with photos and were finished ahead of their schedule and the total cost was actually a bit less than the estimate. Highly recommended.

Jenni★★★★★a year ago

Out of 3 companies, they had the best price. The crew arrived early and was finished quickly, communicating along the way. Even showed me the baffles and where they were going to place them. I got blown in insulation to R 49 and I can definitely tell a difference.

Frequently Asked Questions — Spray Foam Insulation in Portland

These are the questions Portland 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 15 verified Portland contractors above for exact quotes.

How much can spray foam insulation save on heating and cooling bills in Portland?▼
Homeowners in mixed climates like Portland, 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 Portland?▼
For most homes in Portland, 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 Portland, OR?▼
In Portland, 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 Portland costs $2,000–$6,000. Most Portland 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 Portland, OR?▼
When searching for a spray foam contractor in Portland, 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 Portland 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 Portland 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.
