I had the best experience with this company. From start to finish, they made everything easy and stress free. The crew showed up on time, explained what they were going to do, and really knew their stuff. They sprayed foam in my crawlspace and the results were noticeable right away, the floors feel warmer, I don’t feel the drafts anymore, and the space looks super clean. I’d give them 10 stars if it was possible.

We had a great experience using USA Insulation of North Puget Sound! Every step of the process was professional and easy. We worked with Max (owner/coordinator), Jason (estimator), and Jaime (installer). They all listened to our needs and completed the job quickly - and it looks great! Highly recommend working with this team!

Tom was very friendly and straightforward with the inspection, detailed the problems, replacing procedure, and warranties. The decision was made fast with a reasonable cost. 5 stars rate to him. Ronny and his crew are a fantastic hardworking team! They carefully setup their working environments to keep around clean. Then removed all the old insulation, laying up the new ones. When I realized the very small area need to be fixed, upon very tight schedule, Ronny’s crew came back fixed nicely. Yes, Rate Ronny and his crews all 5 stars. The company office has a super service lady Lorrie. She sent the before and after photos, make an inspection schedule, helped the fixed problems… She is friendly, patient, and quickly to resolve the problems! Definitely, Rate her 5 stars. The inspector, Jose, was done a good job and help to resolve our small area problem, Rate him 5 stars too. By my experience, I’m satisfied with this company with good leaders and hard-working teams. I would rate it 5 stars and recommend it to my friends.

At some point over the winter, rats got under our house and shredded everything in their path. I got several bids for the work, not only did Super Attic Solutions offer the best price but they also offered better quality materials for the project, going with them was a no-brainer. Joey who did the appraisal was professional, polite and knew his stuff, joy to work with. They got me scheduled within a week and I got Ricky as my project manager. I’ll say they knocked it out of the park, the crew busted their butts all day and the end result was day and night. The transformation was mind blowing I had no idea how bad the damage was until Ricky and his crew were finished. Our house was built in the 40’s now we have a crawl space and insulation comparable to a new build! Super happy with the results from Ricky’s crew, their professionalism and hard work did not go unnoticed. I highly recommend this company for any insulation-related project. If you get Ricky as the project manager, rest assured the end results are well worth every penny! The company as a whole made this nightmare situation seem manageable and I really appreciate the work! Few Before and after photos below, mind-blown!

This company took care of our attic reinsulation, duct replacement, and rodent infestation all at once. The crew was extremely competent, neat, and on time. A special thank you to Tomer for his exceptional work on the rodent proofing; his thoroughness gave us great peace of mind. The entire process was smooth, and the improvement in our home's air quality and temperature is remarkable. A fantastic job from beginning to end!

Frequently Asked Questions — Spray Foam Insulation in Kirkland

These are the questions Kirkland 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 2 verified Kirkland contractors above for exact quotes.

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