I had many many estimates. Had to be over 15 different companies. I was looking for someone who knew their stuff, gave me decent pricing, had honest (good) reviews, and amazing customer service. I’m so glad I went with 316 because they were so easy to work with. They were informative on everything they were doing, walked me through their process plan, and told me everything that needed to be done. All necessary things. Some other companies were telling me they were going to charge me a crazy extra amount for mold remediation and it was not absolutely needed. (It was a tiny tiny spot) easily cleaned with bleach and water. Even 316 told me how we could accurately clean it ourselves. After choosing them, their customer service was still nothing short of amazing. They wanted to make sure everything was done correctly on their end before proceeding to each next step. They were communicative & punctual, and showed me pictures of the complete job. It looked great! There was a little accident where they broke a part of my chandelier. They gave me the option to fix it or replace it and they would take care of all the fees. (I got a new one) and they installed it and everything. no worries on my part, I just sent an Amazon link of the new chandelier I wanted. They did an amazing job, had amazing customer service, fair pricing, & they offer financing. 316 is by far the superior crawl space company. I recommend them to anyone needing vapor barrier repair and anything in the crawlspace / attic done. Thanks 316!

I had an excellent experience with 316 Insulation from start to finish. Their team was professional, punctual, and clearly knowledgeable about their work. They took the time to explain the process, answered all my questions honestly, and made sure everything was done right—not rushed. The quality of the insulation work was top-notch, and we noticed an immediate improvement in comfort and efficiency. The job site was left clean, and the crew treated our home with respect. It’s refreshing to work with a company that operates with integrity, strong work ethic, and pride in what they do. I would absolutely recommend 316 Insulation to anyone looking for reliable, high-quality insulation work.

We have a 20 year old builder home and my perspective was that the insulation was not sufficient. After listening to my concerns and goals, it turns out it was more correcting some fast and dirty building short cuts, and closing some gaps in the attic that was allowing too much exterior air to penetrate. I appreciated the factual and non-upsell evaluation, which included photos and clear explanations. The communication, scheduling and execution were all really solid. I also felt the value of the work was competitive after getting other estimates.

Christian and his team are wonderful! We've had similarly great experiences as the other reviews. Responsive and quick communication, super respectful of our home (cleaned up thoroughly), did exclusion work carefully, and sourced the insulation we wanted to use at a fair price. Wouldn't hesitate to use them again!

brad jones★★★★★3 years ago

Christian and team did a wonderful job. My house had thin insulation in attic and was drafty and cold. ASAP sealed the air leaks and added R49 insulation to code at a reasonable price. My home is very warm and cozy now.

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! 🙏🏼

Rob the Sales Rep was very through and took the time to make sure I understood all aspects of the job. I got 3 estimates and Clean Crawls was the same or better than the others. The work was done is 2 phases. First was removal of all the insulation in the floor joists and the vapor barrier on the ground in the crawl space. Leo, the crew leader, was great to work with. He built a vinyl tunnel from the access hole inside the house to the front door to mitigate any debris from getting through the house. They also eliminated all entry points into the crawl space to keep the new rodents from coming in. Then the whole space was sprayed with deodorant/sanitizer. The next phase was to eliminate all of the rodents that had made a home in the crawl space. After 2 weeks and 15 dead rodents later we had Clean Crawls come back out to perform phase 2. Being very satisfied with Leo and crew I requested he come back out to finish the job. New vapor barrier was applied and new R30 insulation was installed. The insulation was held in place with nylon cord strung below the floor joists. All pipes were wrapped in R11 insulation. I went down to take a look after the job was complete. I am quite happy with the work performed and have no problem recommending this company.

Job Description: Cleaning Attic and Crawling Space, Removing Old Insulation, Installation of new Insulation, Install Roof Vents (to achieve proper exhaust venting of the attic) and etc. Christopher D Strovas thoroughly inspected the attic and crawling space and gave us the best bid compare to other companies bids. The workers came out the very next day. They showed up on time, worked hard, cleaned up, and completed the project quickly and as scheduled – in 3 days. The entire work crew was friendly and cleaned up very good after the job was done. After the work in the attic was done, we noticed small lines on the ceiling and contacted the office. The supervisor resolved the issue right away. He sent the drywall specialists on the next day and everything was fixed in couple of hours with best result. We are 100% satisfied with the work and will recommend Clean Crawl to everybody who is looking for the descent appraisal and exceptional quality job performance. Thank you, guys, for your excellent work.

Frequently Asked Questions — Spray Foam Insulation in Auburn

These are the questions Auburn 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 8 verified Auburn contractors above for exact quotes.

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