Iowa and Southern Minnesota Homeowners — Stop Heating the Outdoors!

​If your home is:
​❄️ Freezing the moment the furnace kicks off
​🔥 Sweltering upstairs while the AC struggles
​💸 Costing a fortune in MidAmerican or Alliant energy bills
​🌬️ Drafty, dusty, or just plain uncomfortable
​It’s not your HVAC system. It’s your envelope.
​Most homes in North Central Iowa—from the historic houses in Mason City to the farmhouses out by Clear Lake—are leaking air like a sieve. Fiberglass and cellulose just can't compete with the "Iowa Winter."
​At Eternal Spray Foam, we don’t just "add insulation." We seal your home for life.

​What We Do:
​✔️ Professional Spray Foam Only: We specialize in the gold standard of insulation.
​✔️ True Air Sealing: We stop the drafts that traditional insulation ignores.
​✔️ Pole Barns & Shops: Turn your cold storage into a year-round workspace.
​✔️ New Construction: Do it right the first time and save thousands over the life of your home.
​✔️ Crawlspaces & Rim Joists: Stop the cold floors and damp smells at the source.
​Why Choose Us?
​We aren't a "jack of all trades" contractor. We do one thing, and we do it better than anyone else: Spray Foam. We run professional rigs, show up when we say we will, and leave your property cleaner than we found it.
