Alvin sits about 25 miles south of downtown Houston on SH 35, close enough to the Gulf that the air is almost always heavy. This is also the town that set a national record: Tropical Storm Claudette dropped 43 inches of rain on Alvin in 24 hours in 1979, at the time the most ever recorded in the U.S. in a single day. Wet comes with the territory down here.
Brazoria County still has a lot of room — pasture, ag land and acreage around Alvin, Manvel, Liverpool and Danbury — and that's where people are putting up metal shops, hay barns and barndominiums. Steel buildings this close to the coast fight condensation constantly. For the metal buildings we work on, we normally recommend closed-cell foam sprayed directly to the panels, because it keeps humid air off the cold steel and doesn't soak up water the way batts do.
We're based in the Houston area, so the south side is a short run for us. Getting a number is simple: send the length, width and eave height of your building plus your ZIP code, and we can usually price it the same day. If you already have a lower written quote for the same foam type and thickness from a licensed, insured contractor, we'll match it.
What Affects Metal Building Insulation In Alvin?
Coastal moisture
Close to the Gulf, humidity stays high most of the year. Steel that cools at night drops below the dew point and sweats — continuous closed-cell coverage helps keep that moist air off the panels.
A record-setting rain town
Claudette's 43 inches in 24 hours (1979) is part of Alvin's history. Closed-cell foam is listed as acceptable flood damage-resistant insulation in FEMA TB-2 (2025); open-cell and fiberglass are not.
Ag land and acreage
Hay barns, equipment buildings, shops and barndos are common around Alvin, Manvel and Liverpool. We size the foam to how the building is used — an unconditioned barn and a lived-in barndo don't need the same thing.

Alvin Spray Foam FAQ
Don’t see your question? Call or text (346) 505-0304.
Do you serve Alvin and the south side of Houston?
+
Yes. Alvin is about 25 miles south of downtown Houston on SH 35, and we cover Manvel, Liverpool, Danbury, Pearland and Friendswood too. Send your building dimensions and ZIP for a quote.
Why closed-cell instead of open-cell this close to the coast?
+
For the metal buildings we work on, we normally recommend closed-cell foam. Open-cell lets water vapor through to the cold steel, and it can absorb water. Closed-cell is hydrophobic and, at the right thickness, acts as a vapor retarder right against the panel.
Can you spray my boat or RV storage building?
+
Yes. Storage buildings near the coast are prone to condensation that drips on whatever's parked inside. Closed-cell foam on the roof and walls helps cut that. Send us the length, width and eave height and we'll price it.
Do you price match?
+
Yes. Show us a written quote from a licensed, insured spray foam contractor for the same building, foam type and thickness. If it's lower than ours, we'll match it.
