Spray Foam Insulation in Jefferson, LA

Spray Foam Insulation in Jefferson serves one of the first suburban corridors outside New Orleans. The four-lane Jefferson Highway (US 90) opened in 1928 and runs through the center about 6 miles to downtown. Jefferson had 19,353 residents in 1960 and 10,633 in 2020, so its housing is older than most of the parish.

Older homes, older problems

Many homes here are pre-war and early post-war: raised cottages, small bungalows and modest ranches. Attic insulation is often thin, walls may be empty, and raised floors lack insulation underneath. We usually start with the attic and the floor.

Cut off by canals

A drainage canal, railroad tracks and the Earhart Expressway separate Jefferson from Metairie, with Causeway Boulevard and Central Avenue the only public crossings. That drainage canal is a reminder of how wet the ground is. Crawl spaces under raised homes here need a look for standing water.

Raised cottages along the old highway

Jefferson's older streets near the river still hold raised cottages built on piers. The space under the floor is often open on all sides, and many have nothing between the joists or batts hanging loose. On these homes, closed-cell foam on the underside of the subfloor is the most lasting fix. The Department of Energy suggests R-13 for an uninsulated floor in zone 2, and closed-cell reaches that in a few inches. We leave the pier tops clear so a termite inspector can see them, and we look for plumbing leaks before spraying.

Rentals

With a smaller population than in 1960, many homes here have changed hands or become rentals. Landlords often want the work that cuts bills most for the money: attic air sealing and blown-in. Get a free estimate
