Jose and the guys did a fantastic job! A ton of insulation upstairs, main floor, and basement. Plus installing a new door lock and dead bolt. Would highly recommend.

I was really looking to insulate my home due to the very cold climate in the area. I was looking around when I came across JTR insulation LLC! They insulated my home for a great price and the service was amazing.

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

We used Josh Lowes Dr. Energy Saver to renovate our crawlspace; which included removing an existing vapor barrier and insulation, trenched in new drainpipe and sump pump, re-insulated parts of the duct system, and installed a fresh vapor barrier. Brandon, Rico, and Chandler did an incredible job installing the new drainage system and vapor barrier. These guys were very efficient and communicated their progress and look ahead throughout the entire process, offering solutions to help achieve the goals of the install. The attention to detail is very much appreciated, their work looks great and everything appears to be working as intended. Hooper and Nate performed the removal and roughed in the new system; this was not an easy job and commend them on their contribution to the project, and clearing out the ugly part of our space. Monte was a great resource throughout the process and was always very responsive, a great first interaction with the company. You can tell he has wealth of knowledge and experience, and cares about his craft. Due to complications, the work took longer than anticipated; but, every employee that contributed to the cause was polite and treated our home with respect. Based on my experience, if anyone were to be looking to have work done in their crawlspace, I would recommend Josh Lowes. It’s refreshing to have an experience with an organization that is committed to providing a quality product and meeting the needs, and satisfaction, of their customers.

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.

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!

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!

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.

I've used Home Insulation Co twice in the past decade. The crew that just removed and replace my under floor insulation was professional, personable, and FAST! At first my home looked like a disaster site, but they left it looking like they had never been there. My neighbors were impressed! I went under the house the next day and was amazed at how great it looked. In addition they drove all they way to Yachats for a day job.Money well spent!

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.

Frequently Asked Questions — Spray Foam Insulation in Corvallis

These are the questions Corvallis 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 5 verified Corvallis contractors above for exact quotes.

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