Spray Foam Built For Steel
We don’t chase attic jobs. Our rig, our foam and our crew are set up for metal buildings and the people building them.
01Metal Buildings & Shops
Closed-cell spray foam sprayed straight to the steel — walls and roof — to cut heat and help stop the “sweating” that rusts panels and drips on your stuff.

Living side, shop side and the wall between. We foam your barndo shell after rough-in so it’s ready for drywall on your build schedule.

FAQ
Questions We Get Every Day
Still wondering about something? Call or text (346) 505-0304.
How much does it cost to spray foam a metal building?
+
It depends on the square footage of walls and roof, the foam type and the thickness. The fastest way to a real number is to send us your building’s length, width and height plus your ZIP code — we can price most metal buildings and barndominiums from those dimensions, usually the same day. And if you have a lower written quote for the same foam and thickness, we’ll match it.
Do you use closed-cell or open-cell foam on metal buildings?
+
For the metal buildings we work on, we normally recommend closed-cell spray foam. It is denser, adds more R-value per inch, and at the right thickness it slows moisture from reaching the cold steel, which helps with condensation. The exact product and thickness depend on your building and how you plan to use it.
Can you give me a quote without coming out?
+
Usually, yes. Most of our metal building, shop, barn and barndominium quotes are built from the length, width and eave height you send us. If the building has something unusual — tall walls, lots of openings, an existing liner — we may ask for photos first.
How does the price match guarantee work?
+
Show us a written quote from a licensed, insured spray foam contractor for the same building, the same foam type and the same thickness. If it’s lower than ours, we’ll match it. See the price match page for full details.
When should I schedule spray foam on a new build?
+
Once the shell is closed in and your electrical and plumbing rough-in is done, but before drywall or interior paneling. Call us a couple of weeks ahead and we’ll hold a date that lines up with your build.
Do you insulate regular houses?
+
We focus on metal buildings, shops, barns, barndominiums and commercial buildings — that’s where our equipment, foam and experience fit best. If you have an existing-home attic project, we’re probably not the best fit.
What areas do you serve?
+
We serve East and Southeast Texas from the Houston area, including Beaumont, Port Arthur, Cleveland, Dayton, Liberty, Montgomery, Conroe, Alvin, Livingston, Huntsville and Jasper. Larger projects can justify longer drives — send us the details.
