Steven and crew did a fantastic job foaming my new shop. There are so many contractors to choose from, it’s hard to know which way to go. But I got lucky and picked a winner. Very courteous group! On time and kept me in the loop. Protected my new concrete slab, windows and doors. Very neatly done and for a competitive price. I’ll be calling them again for my next project.

HOC Spray Foam Insulation I contracted with HOC spray foam insulation to spay a shop ceiling, approximately 15 ft high. The owners of HOC came out and gave me a bid and explained the process. After our conversation, I quickly received a written bid with total costs listed. One week later two professional installers, Stephen and Owen appeared and again, explained the process. They taped the walls and the floors of the shop, then proceeded to complete the job. When they completed the spray, they asked me to review the project to make sure I was 100% satisfied. Then, after I assured them I was satisfied, they quickly removed the plastic covering the walls and floors, swept the floors to make sure nothing they brought was left. I would, without hesitation, recommend HOC spray foam insulation. They are professional, friendly and proved to be great communicators.

HOC spray foamed our old cabin at Newman Lake. They arrived on time and did a great job. There was one issue where one spot that was to be sprayed got missed. I emailed them that evening and they were out the next morning to take care of it. They cleaned up and were very respectful. We couldn't have been more pleased with the outcome.

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.

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!

Frequently Asked Questions — Spray Foam Insulation in Spokane Valley

These are the questions Spokane Valley 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 3 verified Spokane Valley contractors above for exact quotes.

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