Spray Foam Insulation in Leeds, AL

Spray Foam Insulation in Leeds covers a wider range of buildings than most of the metro. The city incorporated on April 27, 1887, and grew up housing workers and families from the Lehigh Portland cement plant. It stretches across Jefferson, St. Clair and Shelby counties along the Little Cahaba River. Point2Homes' summary of 2019-2023 Census survey data puts the median year built at 1980, with 22% of homes built in the 1970s, 15.5% in the 1980s and 16% in the 1990s, plus 18.7% built before 1960.

Older homes near downtown

Houses from the cement plant era and the decades that followed often have shallow attics, little wall insulation and crawl spaces under raised floors. In these, sealing and insulating the attic floor is the inexpensive starting point. Crawl spaces with open vents take in humid air all summer; a vapor barrier, sealed vents and closed-cell foam on the walls fix that. Walls can be filled with dense-pack cellulose through small holes.

1970s through 1990s houses

These make up the bulk of Leeds' homes. Most were built before Alabama's 2016 code update made a blower door test mandatory, according to Alabama Power's code comparison. Their attics often hold settled insulation and aging ducts, and air leaks around the attic hatch, lights and plumbing are common. Air sealing plus a blown-in top-up handles most of them; encapsulation is worth pricing if the HVAC is due for replacement.

Shops, garages and outbuildings

The edges of Leeds are more rural, with larger lots, detached garages, shops and metal buildings. Metal buildings in a humid climate drip condensation when warm, damp air meets cold steel on winter mornings. Closed-cell spray foam applied directly to the steel insulates and stops the dripping in one step. For framed shops, open-cell or closed-cell in the walls and roof works, depending on how the space is heated and cooled.

Near the river

Homes on low ground near the Little Cahaba River may have more moisture under the floor, so we check drainage before sealing a crawl space. Wikipedia notes the river has long run past the settlement.

Housing units

The 2020 census counted 5,348 housing units in Leeds, with 7.2% vacant and a homeowner vacancy rate of 1.0%. The city's population grew from 6,162 in 1960 to 12,324 in 2020, so newer houses are spread among the older ones.

Closed cell vs open cell for a shop

For a metal building, closed-cell is almost always the choice, since it bonds to the steel, adds rigidity and stops condensation. In a framed shop that will be heated and cooled like a house, open-cell in the walls and roof can do the job for less. If a shop is heated only now and then, the condensation risk matters more than the R-value, which again points to closed-cell on any metal surfaces. We explain which fits your building and use.
