Every spray foam job covers the basics — and the things other crews skip.
- Open-cell foam · R-3.5 per inch · sound dampening
- Closed-cell foam · R-7 per inch · vapor barrier + structural rigidity
- Attic, crawl space, wall, and roof insulation
- Soundproofing and energy-efficiency upgrades
- Structural strength from closed-cell foam
In our years across Wyoming and the Black Hills, we've found that Wyoming winters punish a poorly-insulated attic. Closed-cell foam pulls double duty: R-7 per inch plus structural rigidity that helps a building stand up to wind load.

"Cody and Boston were great — had them do spray foam on two of my projects and garage doors and gutters. They scheduled the work and showed up and did great work with reasonable pricing. Great company!"
spray foam questions, answered.
How do you quote a spray foam job?
We do not publish a public price list. Every spray foam quote is tailored after a free on-site inspection — we measure the area, confirm open-cell vs closed-cell, and pick the thickness that hits the R-value you actually need. Use the spray foam calculator on the site to send us your specs and we will email a quote the same day.
How do you quote a new garage door install in Wyoming?
Every install is quoted after a free on-site visit so the number matches the actual scope — size, insulation grade, opener, and whether we are hauling off an old door. Use the garage door calculator on the site to send us your specs and we will email back a tailored quote the same day.
Are you licensed and insured?
Yes. Seamless Systems LLC is a licensed and insured Wyoming home services company, founded in 2016 by Cody Williamson with over 25 years of combined crew experience in garage doors, gutters, and spray-foam insulation.
What is the difference between open-cell and closed-cell spray foam?
Open-cell foam is softer, lighter, has an R-value of about 3.5 per inch, and is great for sound dampening in interior walls and roof decks. Closed-cell foam is denser, has an R-value of about 7 per inch, adds a vapor barrier, and increases structural rigidity — common in our region for unconditioned shops, metal buildings, and exposed crawl spaces.
How much does closed-cell spray foam cost?
Closed-cell spray foam typically runs $1.00 to $4.50 per board foot installed (one inch over one square foot), depending on access, thickness, and substrate. For an accurate number on your project, use our spray foam calculator or schedule a free on-site inspection — we email a tailored quote the same day.
How much does a new garage door cost in Wyoming?
A new single-car insulated steel residential garage door installed in Wyoming typically falls in the $1,400 to $2,800 range, and a double-car door in the $2,200 to $4,500 range, depending on insulation grade, window options, opener, and removal of the old door. Use our garage door calculator for a rough range or schedule a free on-site inspection for an exact quote.
