Sound Crawls did an excellent job removing and replacing our attic insulation. The bid process was straight forward, communication before and during was excellent, and the four-man team that showed up on time to do the work took every conceivable step I can imagine minimizing impact to the rest of our home while they worked. When they completed the job, I could not even tell they had been here; except for the 50+ pictures they took showing before, during, and after. My wife and I are 100% satisfied.

Patrick, Juan & Octavio from Sound Crawls are exactly what you want. Honest, Quality & Sound work for all of your crawlspace and attic needs. Rodents and critters had decimated my est. 1900 craftsman home’s crawlspace and attic space, Patrick's free on-site assessment and bid was detailed and more knowledgeable than any of the other bidders (who did not bother to show up - they no doubt would have “under-bid” me once they “saw the real job”). They patched up all entry points 3 stories up, from outside the house, completely gutted the destroyed insulation and vapor barrier, installed new everything and used cement filler to patch up any and all access points. They even came back a second day because the job was so big - and did not charge me (or reassess the estimate) for it. This is the crew you want - honest work for a fair price. I will always be using and recommending Sound Crawls for any basement, crawlspace, insulation or attic work needs. Thanks again guys!

We highly recommend Sound Crawls with Patrick and Team. Patrick (owner) and team did an outstanding job on our Camano Island house. Patrick is really easy to work with and he showed great compassion for helping us fix our problems at a reasonable price. We had water under our house and called Sound Crawls to assess. Patrick was quick to come by and give us a complimentary visit to review the issues. He spent close to two hours showing me exactly what his findings were and explaining the options on how to fix it (French drains, sump pump, new insulation). We were very impressed with his knowledge and experience so we decided to go with Sound Crawls. Patrick and team did an outstanding job and we are very happy with the results.

Attic Doctor helped with mold removal in my attic, and the whole experience was excellent. Jay and his team were great to work with from start to finish. Jay was very responsive and clearly explained the issue and the steps they would take, and the pricing was much more reasonable compared to other companies I contacted. His team worked efficiently, and did a thorough job. They were professional and respectful throughout the process. I also really appreciated that Jay provided detailed before-and-after photos, which made it easy to see the original condition and exactly what was cleaned and removed. I’m very satisfied with the results and would definitely recommend Attic Doctor.

Attic Doctor did an insulation job (and air sealing) at my home and I couldn't be happier with the results. They were communicative throughout the entire process, keeping me informed and answering all my questions clearly. What really impressed me was their integrity. During installation, they discovered several exhaust vent ducts that weren't up to code. Instead of charging extra to fix it, they corrected it for free since they hadn't caught it during the estimate. This kind of honesty is hard to find. The work itself was very thorough and well-done. The crew was professional, respectful of property, and left everything clean. Riley and Jay checked in often during the job to ensure things were being executed correctly. They clearly take pride in their work. If you need attic insulation in the area, I highly recommend Attic Doctor! They combine great quality work with honest business practices. I would definitely use them again.

Liz Stone★★★★★a week ago

After doing our due diligence we chose Attic Dr to remove/clean debris from the attic and crawl space, remediate some areas that had mold, remove all old insulation and install new R-38 attic insulation. Both attic and crawl space had all openings sealed and rodent traps were set in place. From start to finish we were very pleased with their process. Pictures of the entire attic and crawl space before, during and after the work was done were reassuring. I would not hesitate to recommend this company. They were professional, responded to any questions we had in a timely manner and left the area around our residence neat and tidy.

I had a fantastic experience with Insulation Pro Inc for my attic insulation project. From start to finish, everything was handled with professionalism and care. Sam, in particular, was outstanding. He was not only incredibly knowledgeable but also took the time to walk me through the entire process, answering all of my questions with patience and clarity. He made sure I understood the benefits of the insulation being installed and what to expect. On the day of the installation, Sam and his team arrived on time and worked efficiently while being respectful of my home. They prepped the area carefully, completed the job quickly, and left everything spotless once they were done. I was especially impressed with their attention to detail and how thorough they were in making sure every corner of the attic was properly insulated. Since the insulation was installed, I’ve already noticed a big improvement in the comfort level of my home, especially with temperature regulation. It’s clear that they used high-quality materials and took pride in their work. If you’re looking for a trustworthy, reliable company for your insulation needs, I highly recommend Insulation Pro Inc—and definitely ask for Sam! He truly made the entire experience stress-free and delivered results that exceeded my expectations.

This team was incredible! After multiple quotes, we ended up choosing this team because of their pricing, transparency, and attention to detail. Eric and Omid did not use any pushy sales tactics or try to give us silly customer discounts. They provided honest assessments and gave rationale answers for the problems in our home. We ended up getting all new insulation in our attic and crawlspace and mold remediation as needed. While assessing the crawlspace and completing that part of the project, they found issues with our sump pump and drain system in the crawl space which needed addressed to fix the moisture issue. The team was so efficient and conscientious in all their time within our home. We felt safe having their team working at our home while we were at work and appreciated all the real time updates Eric provided us with. They were extremely accommodating of our needs and requests, and even respectfully and graciously appreciated the feedback we offered them during one project roadblock. Would recommend this team to everybody needing work done! Thank you so much! 🙏🏼

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!

Aylin Perdomo★★★★★in the last week

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!

PNW Roof & Crawlspace Insulation removed our very old cedar shake roof & installed new high quality metal roof; took off and re-installed our gutters when finished replacing the roof; cleaned out, removed and re-insulated, re-screened, & installed vapor barrier in our crawlspace; cleaned out our attic, & removed & replaced our attic insulation, re-screening all the vents, and removed old fascia and replaced it with new, repainted fascia when the roof installation was completed. They took away all the old materials/garbage, and did a thorough sweep of the premises with a magnet roller after removing all trash materials. When we called for an estimate, PNW answered right away, and their estimator was at our house very quickly.Everyone at PNW couldn't be more friendly, courteous and capable! All the work was done quickly, safely, and on time. Everybody always has a smile on their face, and a hard working, can-do attitude. Their prices are very competitive, and communication was always nothing less than excellent. Their printed estimate and handout given at the time of estimation explains clearly and in detail the work to be done, and the specific type and brands of materials that will be used. All safety procedures, final cleanup procedures, and prices are also listed in detail. We work in the construction trade, and we are impressed. Thanks PN for the wonderful job!!

Alfredo, Ana, and the PNW Roofing crew have been timely, responsive, and super helpful to work with. We had a leak in our roof, Alfredo came out the next day, assessed the issue, provided multiple potential solutions at varying price points and levels of disruptiveness, and was overall very knowledgeable. We were able to have our issue fixed within the week. We have also done roof cleaning and moss treatment on our roof - it looks sparkly and new! We would happily book any roofing needs with this crew again.

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.

While unloading a large amount of heavy asphalt shingles at the Algona Transfer Station two insulation Contractor employees freely and without being asked volunteered their assistance. It took them all of five minutes to each grab an end of the tarp I had laid out under the shingles and dump what would have taken me a full hour to unload. I wanted to publicly thank these two young gentlemen who not only saved me an hour of back breaking work but also for restoring my faith in humanity. Well done and whoever you are I wish you the very best.

Frequently Asked Questions — Spray Foam Insulation in Bellevue

These are the questions Bellevue 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 14 verified Bellevue contractors above for exact quotes.

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