The Classic Metairie Attic
Spray Foam Insulation in Metairie usually starts in the attic. Metairie is an unincorporated area of about 23 square miles at roughly 3 feet of elevation, with 143,507 residents in 2020 down from a 1980 peak of 164,160. That peak tells you when most of its houses went up: the post-war decades, mostly single-story ranches on slabs.
Ducts in the heat
In a typical Metairie ranch, the air handler and ducts sit in the attic. Wikipedia notes Metairie averages 77 days a year at 90F or higher. Attic air on those days far exceeds that. Leaky ducts pull in that air, and thin attic insulation lets heat soak through the ceiling. Foam on the roof deck seals the attic around the ducts; sealing the attic floor and blowing in to depth protects the rooms below at lower cost.
Single-unit homes
The 2019 ACS counted 61,354 housing units in Metairie, 64% of them single-unit and 59% owner-occupied, with a median value of $246,600. Long-term owners tend to want the attic and duct problem fixed once.
Rain and drainage
Metairie gets about 62.5 inches of rain a year. The May 8, 1995 flood dropped upwards of 20 inches in 12 hours. Slab homes that flooded may have had their lower walls redone; we check the attic and walls for leftover damage.
Price check
HomeGuide puts a typical attic insulation job at $1,000 to $2,700 and spray foam on a roof deck at $1,500 to $9,000. For a Metairie ranch, the gap between those two is the main decision, and we price both side by side.

Metairie Questions
Should I seal my Metairie attic or blow in more?
If ducts and the air handler are in the attic, sealing it is worth pricing. If not, air sealing and blown-in usually gives more for the money.
Are Metairie homes on slabs?
Most post-war ranches are. Older homes on the ridge may be raised.
Does the 1995 flood still matter?
Only if repairs left wet or missing insulation. We check for it.
Do you work in Old Metairie?
Yes, along with all of Metairie, Bucktown and Fat City.
