Plaquemines Parish's Biggest Community
Spray Foam Insulation in Belle Chasse serves the largest community in Plaquemines Parish, on the west bank of the Mississippi at about 7 feet. Naval Air Station Joint Reserve Base New Orleans moved here in 1957. Belle Chasse grew from 5,412 residents in 1980 to 12,679 in 2010, then had 10,579 in 2020.
Newer homes, larger lots
Much of the housing dates from the 1980s on, and lots are bigger than in the city. Newer homes usually need attic air sealing and depth, and two-story homes need help at bonus rooms and kneewalls. Many homes also have detached garages or shops.
Lots of land, lots of water
The CDP covers 28.4 square miles: 24.9 of land and 3.5 of water. The name means "beautiful hunting," and the area is still surrounded by wetland. Humid air and low ground point toward closed-cell foam anywhere below the main floor.
Two-story homes
Many newer Belle Chasse homes have two stories or a bonus room over the garage. The upstairs often runs warmer because of attic heat over it, kneewalls with gaps behind them, and the long duct runs needed to reach it. Sealing and insulating kneewalls with foam, sealing and insulating the floor over the garage, and adding attic depth usually even out the temperatures. HomeGuide lists air sealing at $350 to $3,000 depending on the house, and it is often the most effective line on the quote.
Military families
With the base nearby, some families are buying and selling on short schedules. A quick attic sealing and blown-in job is often the best value for an owner who might move in a few years. Get a free estimate
