North Shore, Same Humidity
Spray Foam Insulation in Slidell covers homes from several eras. Slidell was founded in 1882 and 1883 during construction of the New Orleans and Northeastern Railroad and chartered in 1888. Its population jumped from 6,356 in 1960 to 16,101 in 1970 and 26,718 in 1980 during the NASA-era boom, and it had 28,781 residents in 2020.
Slightly cooler winters
Wikipedia notes Slidell's winters are a bit cooler than on the south shore. More cold nights make floor insulation in raised homes more noticeable. Summers are just as humid, so the attic is still the main battle.
Surge history
Slidell sits at about 13 feet, about 3 miles north of the lake. Parts of the city saw surge above 10 feet in 2005, and areas south and east saw 13 to 16 feet. Many homes there were rebuilt or raised; raised homes need their floors insulated with closed-cell foam.
Costs on the North Shore
The same national figures apply here. HomeGuide lists spray foam at $1.50 to $5.00 per square foot installed and blown-in attic jobs at $900 to $3,600. On raised homes, the clearance under the house affects how quickly we can spray the floor, which affects price. Two-story homes take longer to seal than single-story ones. We measure and write the price for each area, and the written estimate is what you pay.
Boom-era homes
Homes from the 1960s and 1970s usually need air sealing and more attic depth. Two-story homes from later decades need attention at bonus rooms and kneewalls. Get a free estimate

Slidell Questions
Do you work on the North Shore?
Yes, in Slidell.
My Slidell house was raised after Katrina. How do I insulate the floor?
Closed-cell foam under the subfloor, sized to the target R-value.

Cooler than the south shore, so floor insulation in raised homes is noticeable.
