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

Tyler and the rest of his crew did a great job with adding spray foam insulation in our crawlspace. The work was just done, but so far I’m really pleased it. The were very accommodating of my schedule and getting their large truck into the small street I live on.

Debbie Stone★★★★★a month ago

Monte showed us every option for the best price. So helpful putting this all together. Tyler and his crew were amazing! They came in like gangbusters and got the job done in way less time than we expected. They were polite, friendly and very helpful. And my goodness, strong! No one stood around. No one bossed anyone around. They were a cohesive team. Great job! Very happy with the results!

My old gutters were broken down and leaking. I am 75 years old and don't want to climb ladders and clean gutters anymore. The Gutter Shutters are heavy duty. They handle twice as much water as my old conventional gutters. They made a big difference in appearance of my 1942 bungalow. Various colors to choose from. They work well. The installation was perfect and fast. Service was great. I doubt that there is a better gutter product on the market.

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.

Marshall's has an excellent team assembled and I received first rate customer service when I recently hired them to replace my thermostat and perform repairs on my HVAC unit. Eden and Katie were both courteous and helpful with getting my repairs noted and scheduled. My conversation and experience with Kevin to ensure that the proper repairs were completed showed me the quality of leadership at Marshall's and made me feel confident that I had made the right service choice. And Donovan provided excellent service when performing the repairs. He is highly skilled and knowledgeable, arrived on time and worked efficiently. I recommend this local business and their team.

Doug Frey and his crew came in and dialed out my addition with a little closed cell foam/blown in insulation combo on the exterior walls and Batt insulation on floor/cap/interior wall and did an awesome job. The benefits of their spray in foam is incredible from the sound deadening to keeping the heat in and the cold out. The place was cleaned up like they had never been there. The guys were very respectful and professional from start to finish.

We were in search for an insulation company and were referred to ECI. I sent in an email request for an estimate and was contacted immediately by Don Drumhiller who set up a time to come look over the project. Don was incredible and offered considerable advice on how to approach the project. I'd had some other estimates but didn't have the comfort level I had with Don and his professionalism. I had ECI do the project and they were terrific, thorough, and provided exceptional service. So glad we went with a number of Don's recommendations and the house heats so easily. Go with ECI and you won't be disappointed.

I am so happy these guys came out today to address my attic insulation. They were on time, neat and organized, articulate, and helpful. They could have just blown in the insulation and called it good but they went farther. They found an unwrapped doorbell transformer buried in old insulation and wrapped it for me. They found a wasps nest in a roof vent and made a recommendation. They evaluated the area and said no mold or leaks were present. They gave me confidence that I was working with good people and I feel like I made a good investment. Highly recommend.

Angela Witty-Bawyll★★★★★2 years ago

These guys did a great job! I called thinking they would be weeks out, as most construction work is, but they were quick to put me on their books for an estimate and to get the job started. We priced them out compared to doing the work ourselves, and they have extremely competitive pricing. Very friendly staff on the phone and hard working guys. They were recommended to us by our builder and we would recommend them to anyone in need of home insulation services.

RussellnBeth Medsker★★★★★a year ago

I highly recommend Home Insulation Co, Inc. I received a free estimate from them that beat two other companies for wall insulation and spray foam attic insulation. When the work was being performed I was asked if I minded if they play music while working (some companies just do it), I didn't hear any yelling or cursing and the foreman (I think that's what he is) was very professional when talking to his crew members. Warm house is a happy house :)

Frequently Asked Questions — Spray Foam Insulation in Eugene

These are the questions Eugene 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 7 verified Eugene contractors above for exact quotes.

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