A 1980s Boom Suburb
Spray Foam Insulation in Destrehan mostly serves homes from the 1980s onward. Destrehan had 2,382 residents in 1980, 8,031 in 1990 and 11,340 in 2020. It sits on the east bank of St. Charles Parish at about 10 feet.
What those homes need
Homes from the 1980s and 1990s were built with insulation, but 30 to 40 years later the attic fill has settled and been disturbed, and ducts have leaky joints. Two-story homes and bonus rooms have kneewalls and floors over garages that were never sealed well. These are the spots we focus on.
History next door
Destrehan Plantation, built around 1780 to 1790, is on the National Register and is a stop on the Great River Road. A handful of older homes near the river need more basic insulation work.
Duct sealing and insulation together
In a 1980s or 1990s home, ducts in the attic often leak at joints and boots. Sealing the attic floor and adding depth helps the rooms, but leaky ducts still waste air. We point out the leaks we see. Some owners have their HVAC company seal ducts the same week, while the attic is accessible. Others choose foam on the roof deck so the ducts sit in conditioned space. We explain the difference and price what you choose.
Spillway and water
The Bonnet Carre Spillway in St. Charles Parish diverts Mississippi flood water to Lake Pontchartrain, and clay from it is used to raise levees. About 12% of Destrehan's area is water. Low ground means we lean toward closed-cell foam anywhere water might reach. Get a free estimate
