Spray Foam Insulation in La Marque, TX

Spray foam insulation in La Marque serves a city that has grown quickly. Wikipedia shows La Marque rising from 14,509 residents in 2010 to 18,030 in 2020, and the Census Bureau estimates 20,324 as of July 2025. The community was first called Highlands and was renamed La Marque, French for 'the mark', in the 1890s.

Homes and owners

Census QuickFacts lists a 68.7% owner-occupied rate and a median owner-occupied value of $206,900. Older ranches tend to have thin attic insulation and walls with little in them; newer subdivisions have better attics but leak around recessed lights, attic hatches and bonus rooms. Ducts in hot attics are common in both.

Rain and humidity

La Marque averages roughly 56 to 62 inches of rain a year, with the heaviest storms from May through October. That much rain and humidity puts a premium on a dry, sealed building envelope. We check for roof leaks and damp insulation before adding anything.

Code baseline

Galveston County is in Climate Zone 2A according to OpenEI. Texas applies the 2015 IECC with state amendments, effective September 1, 2016, and the Insulation Institute's summary lists R-38 for ceilings and R-13 for wood-frame walls in Zone 2. Many older La Marque attics fall well short of that.

Bonus rooms and garages

In newer La Marque two-stories, the bonus room over the garage is often the hardest room to keep cool. Its floor sits over an unconditioned garage and its kneewalls border hot attic space. Closed-cell foam in the garage ceiling and sealing along the kneewalls usually fixes it.

What we usually do

Seal the ceiling and blow insulation to depth, or foam the roof deck when the air handler and ducts are in the attic. Dense-pack thin walls in older homes. Foam under any pier-and-beam floors. Get a free estimate
