Canal Town Homes and Buildings
Spray Foam Insulation in Harvey serves homes and working buildings. Harvey grew from 6,347 residents in 1970 to 22,709 in 1980, so much of its housing dates from that decade. It was founded as a company town by Joseph Hale Harvey around the Harvey Canal, which runs south from the Mississippi toward Bayou Barataria.
1970s homes
Homes from the 1970s often have attics with some insulation but plenty of air leaks, and ductwork that has been patched over the years. Sealing the attic floor and topping up the depth usually comes first.
Industrial steel
The canal has long been a working waterway, with marine businesses and steel buildings along it. Bare steel sweats in this climate. Closed-cell foam on the inside of roof and wall panels stops the drip and cuts heat.
Metal building costs
HomeGuide lists closed-cell foam at $3.00 to $5.00 per square foot installed, and many crews have a job minimum of $1,000 to $2,000 or more. On a steel building, wall height, the panel profile, lift access and whether a protective coating is needed move the price. We measure the roof and walls separately and list them separately, so you can do the roof first and the walls later if budget is tight. Roof steel usually drips the most, so it is the common first phase.
Low ground
Harvey sits at about 3 feet of elevation. For any building likely to see water, we lean toward closed-cell foam that does not soak it up. Get a free estimate
