Chris was very prompt to come out and look at our shop. Once we decided what to do he had the crew there in a couple days which was appreciated. We had the ceiling sprayed and the walls batted. Hunter and the crew did a great job and took care of the details to make sure we got the best product.

Hunter, Audrey and Nick did an amazing job on my shop. The company is fast, clean and on point with pricing. I wouldn't go anywhere else.

We started using Sunvek a few years ago and we depend on them to make repairs . They show up on time do a great job and clean up any mess made. We trust them to do the job .

Dan Gilbert★★★★★2 years ago

I found John and his crew and gave him a call. He came out promptly and gave a quote. The job was approved and his team worked their tales off during the heat of the summer and did an amazing job. I had John look at another property that I thought needed a whole new roof and he talked me out of it and fixed a few issues and we have had only one leak, and John came out and fixed it. Prior to his and his crews work, we chased about 20 leaks last spring. Honest, hard working, won't sell you what you do not need.

Jessica Wiltfong★★★★★2 years ago

As a General Contractor in the greater Spokane area, we highly recommend Sunvek to every client of ours for commercial or residential roofing and insulation needs. Their product is phenomenal and they have an exceptional team!

Gus gave me excellent information over the phone to save me plenty of time that I could use doing other things. Estimate given, quote an invoice sent. Is crew showed up early which was great and quickly completed the job. They vacuumed and cleaned up after themselves, it was like they were never here. Look forward to seeing the savings in my heating bill this winter. Will easily recommend them to my neighbors who have the same insulation issues that I had. Thanks again Gus

I can’t say enough great things about this company. I reached out for help with my energy bill through Avista’s insulation program, and they connected me with Gus at Pacific Insulation and Mold. Sam came out to do an assessment and shared some helpful insights on what improvements could make a difference. Gus was very personable and informative when I asked for a quote to insulate my crawlspace. The following week, his team came out, and one of the installers noticed that my crawlspace was already insulated to code. He explained that adding more insulation wouldn’t lead to much additional savings, which I really appreciated—it saved me money. He also suggested that upgrading my heating system would be a more effective way to improve efficiency and reduce costs. Thank you to everyone for your honesty and great service. I’d absolutely recommend this local small business to anyone, and I’ll gladly work with them again if I ever need to in the future.

Emily King★★★★★2 weeks ago

After having several people working on other projects on the home mention that I had a little to no insulation, I called Pacific Insulation to explain the situation. They worked me in on a Saturday morning, and when they came, it was discovered that I actually had plenty of insulation! They informed me it would not be of any benefit to spray additional cellulose, even though they were already there and set up. They easily could have just sprayed in more insulation and gotten paid, since I clearly had no idea what was going on in the attic, but instead saved me money with their honest and professionalism! I would highly recommend them!

John Schneider★★★★★2 months ago

We have a very complicated attic owing to multiple vaulted ceilings and skylights. This made it a challenge to do the blown insulation work we requested, but it appears the USA Insulation crew took their time, put in a long day, and did the job right. We appreciate their hard work.

Julie Reed★★★★★2 months ago

Thank you Daryl and your team for blowing in the insulation to the attic! Your team was friendly, funny and professional! They did a great job! I will recommend your team to everyone!

Eric Smith★★★★★a year ago

Having just moved into a place with a brand new, and not yet insulated metal shop, I started the process of finding a contractor who could do the job. After about two weeks of searching, leaving my name and number and rarely receiving a call back, I checked on Angie's List and found Specialty Insulation. They replied to me the same day and we arranged for the salesman, Jordan Richardson, to drop my and give me an estimate. I was very happy with the two types of insulation services they offered and went with the R21 Fiberglass insulation with a WMP VR-R wrap covering. The job was started within a week and finished in three-days, despite the recent cold snap with temps in the negative numbers. The installers were curious, professional and always on time and great to talk too. I'm very happy with the job they did, and my shop looks fantastic, plus, its warm! I would highly recommend Specialty Insulation!

Wendy Acosta★★★★★2 months ago

Our 1930ʻs cottage needed TLC and the right insulation to fill the wall cavities. Specialty not only knew what we needed, (blown in cellulose), they were able to get it done in time to beat the next heat wave. Decades ago I used Specialty Insulation. It was gratifying to see that their quality, integrity and service are still stellar. Mahalo for taking care of us!

Katie Magnuson★★★★★a month ago

Specialty did multiple projects for us and our point of contact, Manuel Escobar maintained great communication with us throughout. He was friendly and quick to respond to questions and last minute requests. All the crews who worked on our home were respectful and courteous.

Pacific Insulation arrived when they said they would and performed the job efficiently, and cleaned up when they left. They also brought the necessary rebate forms so I can claim a rebate for the job done. I would recommend this company.

All of the folks at superior insulation were amazing to work with. Ted was very informative and precise with his estimate and took the extra time to explain everything to me and answer all my questions. The instal team did an amazing job and left virtually no mess either! They were all easy to work with as I was out of town while they did it. I really appreciate Jade, Ted and the instal team for all of their great work and highly recommend them to anyone!

Michael Howard★★★★★2 months ago

We had our attic and crawl space insulated, and the team did a fantastic job. I worked with Andrew, one of the project managers, who was knowledgeable and always responsive to my questions. They’re an Avista-approved vendor for the new rebate program, which requires much more picture documentation and is more involved than in the past. Andrew handled all of it seamlessly through Avista’s new portal, making the rebate process smooth and stress-free.

We recently bought a new home, and the garage door had clearly been installed by an amateur — it was done wrong in every way. Intermountain West Insulation made the whole process smooth and stress-free. Brandon, the installer, did an amazing job putting in the new door and opener, and everything works perfectly now. Friendly, professional service at a fair price. Highly recommend!

Wow, excellent service. Every new home owner should have this inspection. I was concerned about “old house smell” and fearful of any hazardous air issues in my recently purchased 1930s brick Tudor. John did such a thorough inspection and gave me such tremendous peace of mind with his advice and knowledge of mold, asbestos, and any type of building material that could be potentially harmful. I could not believe he was willing to do such a thorough initial inspection for free! He basically gave me free advice about how to remedy some minor hazards and did not charge me anything. I didn’t end up needing any further services but I would certainly call them if I needed any type of air/materials testing. He did not try to sell any additional services that were not needed and all I need to do is paint over some minor areas of lead paint/asbestos. So much more helpful than traditional generalist home inspections! I know my house is safe now for my baby.

John Graves is great! He does a ton of testing for us and is very timely in fitting us in his schedule. He follows up with prompt report to post it on our jobsites so we can get to work.

Frequently Asked Questions — Spray Foam Insulation in Spokane

These are the questions Spokane 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 13 verified Spokane contractors above for exact quotes.

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