Old Homes Behind the Levee
Spray Foam Insulation in Gretna often means older homes. Gretna is the Jefferson Parish seat and its second-largest city, with 17,814 residents in 2020. It was settled in 1836 as Mechanikham, and McDonoghville, founded in 1815, was the first subdivision in Jefferson Parish. The city incorporated in 1913.
At sea level
Gretna's elevation is about 0 feet, behind the levee on the west bank across from Uptown New Orleans. Raised homes in the older blocks have humid air under the floor all summer. Closed-cell foam under the subfloor seals the drafts and keeps the framing drier.
Historic houses
Older Gretna houses have tall ceilings, empty walls and attics that were never insulated well. Dense-pack walls, attic air sealing and blown-in, and foam under the floor are the usual steps. We work from inside and below so finished rooms stay intact.
Working in old houses
Older Gretna homes may have plaster walls, heart pine floors and old trim that owners want to keep. We protect floors, cover furniture and work from the attic and under the house whenever we can. Where walls need insulation, small holes for dense-pack can be drilled from outside under a siding board and the board put back. If your house is in a historic district and work would change the exterior, check with the city first. Most insulation work changes nothing you can see from the street.
Water in the city
Gretna covers 3.9 square miles, about 9% of it water. A river flood in the late 1800s destroyed the Monplaisir plantation house. Water has always shaped the West Bank, and insulation that may get wet should be the kind that does not soak it up. Get a free estimate

Yes, and throughout Gretna and Terrytown.
What if my attic has old wiring?
We check it and recommend an electrician before covering it.
