Spray Foam Insulation in Gardendale, AL

Spray Foam Insulation in Gardendale has to handle two eras of houses. Point2Homes' summary of 2019-2023 Census survey data shows a first wave in the 1960s and 1970s (16.7% and 13.9% of today's homes) and a second from 2000 to 2009 (19.7%), with a median year built of 1988. The town was known as Jugtown, after a large jug and churn factory, until residents chose the name Gardendale in 1906. It incorporated in 1955 and grew from 4,712 residents in 1960 to 16,044 in 2020.

The land under the houses

Wikipedia notes that the area once yielded large amounts of coal and still has several old, closed mines and former strip-mined lands, and that the east and northeast sides are rocky and hilly with deep ravines. Streams here drain toward the Locust Fork of the Black Warrior River. Hilly lots mean many Gardendale houses sit on crawl spaces or partial basements with one side exposed, and water running downhill toward a foundation is something we look for before sealing anything under a house.

1960s and 1970s homes

Ranch houses from this era usually have a shallow attic with a thin, settled layer of insulation, walls with early fiberglass batts or none, and a vented crawl space. Central air was often added later, with ducts run through the crawl space or attic. Sealing the attic floor and blowing in insulation to the Department of Energy's Zone 3 recommendation is the inexpensive first step. In the crawl space, a vapor barrier, sealed vents and closed-cell foam on the walls stop the summer dampness that makes ducts sweat and floors feel clammy.

2000s homes

The newer subdivisions mostly put the HVAC in the attic and often include bonus rooms. Their attic insulation has had about 20 years to settle, and they were built before Alabama's 2016 update made blower door testing mandatory, according to Alabama Power's code comparison. Air sealing the attic and topping up the insulation helps; if ducts or equipment need replacing, attic encapsulation is worth pricing too.

A note on basements

Where a Gardendale home has a partial basement on a slope, closed-cell foam on the exposed walls and the rim joist insulates and slows moisture through the block. If the basement takes on water after heavy rain, we recommend fixing drainage first.

Housing units and occupancy

The 2020 census counted 6,854 housing units in Gardendale, with 5.0% vacant and a homeowner vacancy rate of just 1.3%. Most homes here are owner-occupied family houses, and the owners usually plan to stay long enough for insulation work to pay back in comfort.

Picking the right contractor

When you call insulation companies around Gardendale, ask whether they will crawl the space under the house and go into the attic before quoting. A price given without that look is a guess. Ask too how they plan to handle a crawl space on a slope, where water from uphill is part of the problem.
