Great experience with this spray foam insulation team. They were on time, kept the area very clean, and listened carefully to my concerns about chemical smells and foam on the floor. I have dogs, so that attention to detail really mattered to me. My house is already warmer, and I’m very happy with the results. Highly recommend.

Will was great and our shop is warm now! Great communication throughout the project, stayed on budget, and ended up ahead of schedule! We called several contractors and highly recommend working with Turnagain Spray Foam!

Great, friendly service. Will was very accommodating in getting work done within a tight timeline. They were careful of our belongings and respectful. The insulation looks great. We hope to employ them again for future projects.

These guys came out on a Saturday, in pretty gnarly winter driving conditions, and did an exceptional job putting baffles and blown insulation in my attic. I appreciated their attention to detail and way they went about the work. Definitely recommend.

Kathy★★★★★2 years ago

They just did the blown in insulation in my attic. When contacted he came and gave a bid. We accepted and he told us to call him the second week of July to schedule. Came out just a few days after that call. This was to add more insulation to the existing.

Urethane Alaska did a complete insulation job on my recent home renovation project. They walked me through the whole process and made the job go smoothly. They even sprayed the attic ceiling between the trusses where it meets the walls, since the blow-in insulation doesn't provide much cold resistance in that small corner space. They were quick and did a great job cleaning up after themselves. My old house with 2x4 walls is going to be toasty this winter, and my gas bill should drop tremendously!

Heidi Tauschek★★★★★5 years ago

I am very pleased with the quality of work Urethane Alaska did for me. Luke Smith and his workers came and put an entirely new vapor seal in my crawl space, taped it off, and insulated ground to ceiling. They sealed off old broken down vents that were letting in too much cold air (and keeping my floors about 20 degrees colder than the house), and put in a new one with a fan to keep air circulating. They hauled off all the old insulation and left no trace of mess behind. They even moved and replaced all the home renovation stuff (paint cans and flooring planks, stone tiles, extra supplies) I forgot I was storing down there - without complaint! The service was excellent, the work was done in a single day for my home, and they ventilated everything. They even followed up to make sure I was happy - I AM! My heating bills decreased by a whopping 17% -- that's how much improved the insulation is now. My feet stay warm on the floor and everyone who visits comments on the improvement. It has mane an enormous difference, and I couldn't be happier.

Very professional job on our challenging geodesic dome project. In fact, I just had to cut into the rim joist to install a fan duct and found that these guys even got insulation evenly installed in a tight spot where they had to spray through a small knockout! Closed cell foam is a great product when installed by real pros, so make sure to go with people who will do it right!

Have a small cabin with tight space to work, the crew was like, we got this. Absolutely the most positive work crew I have met in years. Great customer service from the owner to the staff. Highly recommend.

Exceptional Quality and Service From Large Commercial Projects to My Own Home and Cabin I’ve worked with Alas-Co Insulation on multiple large commercial jobs over the years, and they’ve consistently delivered outstanding results. Their team is professional, responsive, and deeply knowledgeable about Alaska’s unique building challenges. From moisture control and vapor barriers to achieving the right R-values for energy efficiency in our climate. ***And surprisingly honest! No upsell just facts about what I needed to do v what I was willing to do which saved me 💰💰💰💰💰💰 What’s most impressive is their range. They bring the same precision and care to major multi-unit or commercial projects as they do to smaller, more personal jobs. I’ve used them not only for large-scale builds but also for insulation upgrades at my own family home and even my cabin and the workmanship has been flawless every time. The crews are punctual, respectful of the property, and meticulous with cleanup. You can tell they take real pride in their work. In an industry where consistency can be hard to find, Alas-Co has proven time and again that they’re reliable, detail-oriented, and committed to excellence. I highly recommend them to anyone looking for insulation done right, whether it’s a commercial development or a small family project. They’re a true Alaska company that stands behind their word and their work. — Brandy P., Anchorage, AK

After taking a fall in my family room, Ed Pico of Alas-Co was kind enough to do a fabulous repair of the hole in my drywall. After repairing the drywall he also textured and painted the wall during his three day weekend off work. After the paint dried, you can not even tell that the large hole was in my wall next to the fireplace. I have been meaning to write this review for awhile and let Alas-Co know what a great job Ed did to help me out. Plus he would not let me pay him which even showed me more class from a first rate worker and neighbor. Thank you Ed for doing a nice job!

The crew came and installed a vapor barrier and insulation in the crawl space day one, the second day they used "aeroseal" on the duct work and reduced leakage by 97%, which their printout showed in an easy to understand manner. They covered everything in plastic, even taking the time to cover the fish bowl and poke a little air hole in it. There were a couple of minor things that weren't perfect but they did a good job all in all, and the quote was the price I was charged. They were fair, clean, and easy to deal with. I'm looking forward to a healthier house and a more efficient and comfortable winter.

Rhett Paulson★★★★★6 years ago

Fantastic work. I'm extremely happy with the spray insulation that they added to a remodel project and in my crawlspace. I would highly recommend Ryan and his crew.

Zachary Vincent★★★★★3 years ago

The guys made sure our attic was air tight and insulated they were very thorough, clean and professional. Great job!

Frequently Asked Questions — Spray Foam Insulation in Anchorage

These are the questions Anchorage homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 23% typical energy savings. Compare the 8 verified Anchorage contractors above for exact quotes.

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 Anchorage, AK?
In Anchorage, AK 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 Anchorage costs $2,000–$6,000. Most Anchorage 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 Anchorage, AK?
When searching for a spray foam contractor in Anchorage, AK, 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 Anchorage 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 Anchorage 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.
