Great customer service, best price, and very happy with the product.

Garrett★★★★★a year ago

Just had 4 inches sprayed on the underside of our flooring. Scott came out to do the work and was incredibly friendly, punctual, communicative and an all round pleasant human. Robert was also very friendly and easy to work with regarding a quote and scheduling. Would definitely recommend trying them out.

I could not be happier with Insul-Max. They showed up on the agreed/scheduled day and they finished up on the agreed/scheduled day. The guys stayed all day both days so they did half of a 36X48 with 14 foot ceilings pole barn style shop one day then gave me the weekend to move stuff over to the other side. Then they did the other half of the shop Monday. The guys obviously know what they are doing and are very hard working and careful and very accommodating for what I needed and they work really well together. The finished product looks great. Last night I checked my shop when I closed it up and it was 44 degrees in there then over night it got down to 24 degrees. I went in the shop in the morning when it was 29 degrees outside and inside the shop it was 42 degrees. 2 to 3 inches of foam with no stove or heaters on and it only dropped 2 degrees overnight. That is so amazing!!! I highly recommend Insul-Max.

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.

We just hired Daryl and his hard working crew from USA Insulation of Spokane to insulate our attic with blown-in fiberglass insulation. My wife and I were very pleased with their politeness and professionalism. They answered all of our questions, were on time and even placed tarps on the carpet to walk on. What a difference going from R-11 to R-60 with consistant temperature in our home. May not need to purchase that air conditioner now! Thank you Daryl and crew with USA Insulation of Spokane.

T. Wagoner★★★★★4 months ago

Daryl and his crew were outstanding. With one day’s notice they rescheduled appointments to insulate our attic so we could meet an Avista rebate deadline. They placed down tarps, and left the house very clean. Daryl made sure I had all paperwork, and communicated very well. Highly recommend.

Jack Tatum★★★★★4 months ago

Edit to my review: The salesman (Daryl) reached out immediately after my initial review and offered to come take a look at the work. He explained some of the areas that I had concerns with and offered to make right other areas that didn't meet their standards. A direct quote from him "What matters is that your expectations are met." Very pleased with the professional follow-up and communication. I'll definitely be using them again. The salesman was great, and instalation team was very professional. The blown-in insulation was top-notch from what I can tell. However, my one complaint is about the spray insulation. The work done was pretty messy and inconsistent. Additionally, the installers didn't remove the old fiberglass insulation before doing the spray. Im not sure if this is standard practice but it didn't seem quite right. Also, the diagram that the salesman provided the installers allegedly didn't include all of the areas tonbe spray foamed. Overall, I'd go with these guys again, but just get some clarification on specifics first.

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.

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 10 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.
