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 old insulation removed from attic and new stuff blown in. Crew was very thorough and clean. Highly recommend.

Aidan Lee★★★★★2 months ago

We had our old attic insulation removed and new insulation installed. It was such an enjoyable and easy experience to work with Emmanuel and the Hiprovac team. They worked quickly, took the time to explain everything that they were doing, and went the extra mile to make sure all of the details were completed. We can immediately feel the difference in the temperature in our home. 10/10 recommend

Sean Merrill★★★★★a year ago

From the time of first contact, Hi-Provac was very professional and timely in their communication. We scheduled a day for them to come out, and after a few hours of work they were done vacuuming out the attic. The results were better than I expected, and well worth the money spent. I'm happy I didn't try to DIY the insulation removal.

We love our new heat pump! It's our sole heat source and keeps our house much more comfortable than our Nest-thermostated gas furnace ever did. Have used it for cooling only a couple days, so we're still figuring that out. But we've been very, very pleased so far. And GreenSavers did a fabulous job: very neat and professional. They rock!

Tzvi Y★★★★★5 months ago

I had a fantastic experience with Ben Braudy and Zach Hamlin at Greensavers! My AC unit went out during a heatwave, and Zach responded quickly and professionally. He diagnosed the issue right away, explained everything clearly, and had it up and running in no time. You can tell he knows his stuff and genuinely cares about his customers. I really appreciated his honesty, efficiency, and great attitude. Highly recommend Zach and the team at Greensavers if you need HVAC help!

Andrew Dickson★★★★★5 months ago

Edit: Our project had initially fallen through the cracks due to miscommunication. Craig and Heather at GreenSavers got in contact with us, were very professional and amicable, and worked to get our project on track and make the situation right. The quality of interactions with Craig and Heather restored our confidence in moving forward with GreenSavers and it speaks to their professionalism. They insulated the crawl space, the ceiling, replaced the heating and AC unit, installed a much needed kitchen ventilation fan, cleaned and repaired the ventilation, and replaced the front door that wasn't up to code and an old window that both showed through energy audit as our biggest sources of temperature bleed with the outside. There were a couple hiccups during the whole process but GreenSavers worked to correct any issues and were very responsive throughout the whole project. I've seen insulated attics and crawlspaces before but the work they did is a different level of clean and sealed. The AC's pad was not stable, so they also replaced the pad and leveled it, and did the work with no disruption to the yard and plants around it. The front door originally on the house was not the right size or type, and had almost a 1/16 inch gap. They ordered and handled getting a proper solid door, fixing the frame, and repainting the door and frame to match the house. The window had a similar problem as the door that they corrected. Since completing the project, the AC can actually keep the house at a comfortable temperature on hot days, the heating is finally effective at warming the house back up on cold days, and the overall efficiency improvement cut our gas bill in half, and our electric bill by about 1/3, not to mention the tax credits they got us. Since cleaning and repairing the vents and sealing everything, I no longer have as bad of congestion problems from the dust, our infant son's room stays at a very comfortable temperature overnight, and he's stopped sneezing when the AC or heat comes on. The kitchen had no ventilation, so they installed a fan above the stove and it has worked wonderfully. Their work was impressive enough we kept their sign up on our yard for almost 3 months after the project finished, recommended them to a couple friends that were planning to do house work, and we plan to continue recommending them. ---------Initial Review--------- My wife and I contacted GreensSavers in November, worked with Brittnee and Tom, got an audit done, made plans for work to be done. Then they ghosted us and aren't responding to contact attempts. We're now out $400 and have effectively been scammed.

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.

Chris Reaves★★★★★6 years ago

Our installation crew, Sammy and Johnny, were prompt, courteous and professional. The completed the job quickly and effectively. They were able to cover all surfaces of a difficult roof and left our attic cleaner than when they arrived. I recommend IBP without reservation.

It's not the right location showing on maps but is on the other side of the building shown. Pretty tight dock and back area for a full-size 53ft plus truck but doable. Friendly staff when checking in/out and decent unload times. Overall, it was a good experience

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 11 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.
