Insulating the City Itself
Spray Foam Insulation in New Orleans means working on a housing stock that is older, more varied and more exposed to water than almost anywhere in the country. Wikipedia names shotgun houses, bungalows and Creole cottages among the city's signature building styles, and many of them sit on brick piers with open air beneath the floor. A 2016 study cited there found about 65% of the city at or below mean sea level.
Low ground, high water table
Elevations run from about 20 feet at the Uptown river levee to about 7 feet below sea level in eastern New Orleans. Air under raised floors is humid all summer, and water can pool beneath houses after heavy rain. Closed-cell foam under the floor, and liners where the space is enclosed, are the usual fixes.
Owner and renter homes
Census QuickFacts puts owner occupancy at 51.2% and the median owner-occupied home value at $315,700. About half the city rents, and landlords often call us about high tenant bills in older doubles. Sealing the attic floor and insulating under the floor makes the biggest difference in a double shotgun.
Storms
Katrina flooded more than 80% of the city in 2005. Many homes were gutted and rebuilt. If yours was, check what went back in the walls and under the floor; rushed repairs sometimes left gaps.
Doubles and rentals
In a double shotgun, both units share the attic and the space under the floor. Insulating one side alone leaves the shared wall and the open framing on the other side leaking. We usually quote the whole building and list each unit's share, so owners and landlords can see the cost per side.
Heat
The airport hit 105F on August 27, 2023, its record. Attics with ducts in them are the hottest spaces in the house. A sealed attic or a well sealed and deeply insulated attic floor is the first step for most slab homes and camelbacks. Get a free estimate

New Orleans Questions
What should I insulate first in a shotgun house?
Usually under the floor and the attic floor. Side walls come next.
Can you work in the French Quarter or Marigny?
Yes. Most insulation work is done from inside and does not change the exterior.
Is spray foam safe under a raised house?
Closed-cell foam is the usual choice there. We leave pier tops clear for termite inspection.
Do you serve eastern New Orleans?
Yes, along with Gentilly, Lakeview, Uptown, Mid-City and the West Bank of the city.
