It's pretty rare to find a home service company that offers 2 major services for your home, That actually do a great job on both. Summit Insulation And Door's is one of those rare finds. During our home building process as a rule of thumb we always would have 2 to 3 bids, and it never was about the lowest bid. It was about the overall experience and level of confidence we had with the company we ended up choosing. After dealing with three bids for full insulation in our new build and three beds for garage doors, it was clear from the very beginning Summit Insulation And Door was the company we would move forward with. We interacted with Jeremy the owner through the bidding process of the insulation and Dakota, who is the head of the Garage door division. In regard to the Insulation it was something I thoroughly researched and had planned out what was best for our purposes of our home. And speaking with Jeremy, his professionalism and experience with not only foundational knowledge of insulation best practices, but his knowledge of newer technologies, materials etc was something I did not experience with the other bids. Building an efficient home, there are many things to consider. Not only did Jeremy and I walk through each step of attic insulation, roof insulation, creating air flow sections for reducing ice build up, room by room sound insulation, mechanical room sound damping etc, we talked things through so in depth and made me feel truly part of the process. The first major phase of the insulation process went exactly as planned. The spray foam sections, the insulation parts and sound deadening between rooms was absolute perfection. I will report back on final attic insulation in a few weeks but anticipating the same level of top notch service. The Garage Door process with Dakota was second to none. We had very specific needs for our garage doors. Taller than normal, needed to be built from cedar and built thicker than normal and some rough ideas on the look and feel. Dakota listened to our needs and came up with some amazing design versions in hours, not weeks. He quickly led us to the final design, along with going over the craftsmanship needed to build the garage doors that are to last a very longtime. Once they are stained in the spring we will update pictures. I highly, highly recommend to have Summit Insulation and Garage Doors part of your bidding process and you will experience the same I have, 5 star service at a very competitive price! Great Job!

Summit Insulation is fantastic. We had them bid on a big garage door including the installation. Dakota and Rita made sure everything happened seamlessly, including the weather stripping, the handles, the opener, and any tweaking of the door to have it fit just right, especially the bottom edge. We liked them so much we had them come back to insulate a new build. When we need a garage door or an insulation job again, Summit will be our first call. Thanks, guys!

I highly recommend Summit for any garage door problems. They are quick to respond, provide fantastic service, and have fair pricing. My garage door spring broke on a Friday night. I reached out to them and Dylan showed up Saturday morning and got it fixed. I’m incredibly impressed with the quality of service and pricing that is far less than competitors.

I was feeling really hot in my house this summer and come to find out that they can add insulation to my attic for a fair price. They workers were super nice and clear knew what they were doing. They were in and out in a jiffy. Couldn’t have asked for better service. Thanks Merlin’s Insulation!

These guys are quick, efficient and do fantastic work for a fair price! I wouldn't hesitate to use them for any insulation job you need done. Not only did they do a nice neat job on my basement ceiling, they were sure to clean up any mess they created and left my house the way they found it. Great job Merlin's Insulation!

Maggie Hawkes★★★★★6 years ago

These guys are awesome! They offer a high quality product (none of that nasty cellulose) at a good price. The crew was very kind (especially to my son--and even let him help!), worked efficiently, and left us warm and snug. Highly recommend!!!

Frequently Asked Questions — Spray Foam Insulation in Pocatello

These are the questions Pocatello homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 37% typical energy savings. Compare the 2 verified Pocatello contractors above for exact quotes.

Why is spray foam insulation especially important in cold climates like Pocatello?▼
In cold climates like Pocatello, ID, proper insulation is critical to preventing heat loss, ice dams, and frozen pipes. Spray foam's air-sealing properties stop the cold air infiltration that traditional insulation cannot address. It also prevents the moisture buildup inside walls that leads to mold in cold-weather freeze-thaw cycles. Homeowners in ID typically save 25–35% on heating costs. Note: in tightly sealed homes, proper mechanical ventilation is commonly recommended to maintain fresh air exchange without losing the heat you've paid for.
Does spray foam insulation prevent ice dams in Pocatello?▼
Yes — spray foam insulation is one of the most effective solutions for preventing ice dams in cold climates like Pocatello, ID. Ice dams form when heat escapes through a poorly insulated attic, melting snow that refreezes at the eaves. By creating an air-tight thermal barrier in the attic, spray foam eliminates the heat loss that causes ice dams in the first place.
What R-value do I need for spray foam insulation in Pocatello?▼
For cold climates like Pocatello, ID, the Department of Energy recommends attic insulation of R-49 to R-60. Closed-cell spray foam provides R-6 to R-7 per inch, meaning 8–10 inches achieves code-minimum performance. Open-cell foam at R-3.5 per inch requires greater thickness. A local contractor familiar with ID building codes can recommend the exact specification for your home.
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 Pocatello, ID?▼
In Pocatello, ID 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 Pocatello costs $2,000–$6,000. Most Pocatello 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 Pocatello, ID?▼
When searching for a spray foam contractor in Pocatello, ID, 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 Pocatello 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 Pocatello 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.
