Spray Foam Insulation in Kemah, TX

Spray foam insulation in Kemah works around salt air and storm surge. Wikipedia places Kemah on the west shore of Galveston Bay at about 6.6 feet above sea level, bordered by League City and by Seabrook across the Clear Creek Channel. Clear Lake beside it is a brackish harbor with one of the largest concentrations of recreational boats and marinas in the country.

Storm history

Hurricane Ike made landfall in Galveston County on September 13, 2008, destroying homes and businesses in Kemah. A waterline in a boardwalk restaurant still marks the flood level. Raised homes and rebuilt homes are common, and insulation under raised floors and below flood elevation should be water-resistant: closed-cell foam is the usual choice.

Part-time homes

The 2020 census counted 1,807 residents and 860 housing units in Kemah, with 16.2% vacant. Homes that sit empty for stretches benefit from a tight, well-insulated envelope that keeps heat and humidity down.

Code baseline

OpenEI places Galveston County in Climate Zone 2A, where the Texas code summary lists R-38 for ceilings and R-13 for wood-frame walls. The Department of Energy suggests R-13 for an uninsulated floor in Zone 2.

Checking for corrosion

Salt air from the bay reaches framing connectors, straps and fasteners under raised homes. Before spraying foam under a floor, we check those parts for corrosion and point out anything that should be repaired first, because foam makes them harder to inspect later.

Rentals and second homes

Kemah's mix of part-time homes and rentals means many houses sit closed up during hot weather. Sealing the floor and attic keeps humidity down while no one is home.

Attics

Attics with ducts are common here too. Roof deck foam or a sealed ceiling with deeper insulation both work, depending on the layout. Get a free estimate
