Spray Foam Insulation in Dickinson, TX

Spray foam insulation in Dickinson has to account for flooding. Wikipedia reports that about 90% of the city flooded during Hurricane Harvey in 2017, and about half was destroyed by flooding. Dickinson sits at about 9.8 feet above sea level, with Dickinson Bayou running through the city, where settlement began before 1850.

Rebuilt walls

Many Dickinson homes had their lower walls opened and reinsulated after Harvey. Where walls are being opened again for remodeling or repairs, closed-cell foam is a good choice in the lower part of the wall because it does not absorb water. Above that, open-cell foam or other insulation can work well.

Attics and ducts

The attic is still the biggest source of summer heat gain in most homes here. Sealing the ceiling and insulating to depth, or foaming the roof deck where ducts are in the attic, are the usual recommendations.

Code baseline

OpenEI places Galveston County in Climate Zone 2A. Texas applies the 2015 IECC with state amendments, and the Insulation Institute's summary lists R-38 ceilings and R-13 wood-frame walls in Zone 2.

Checking what the rebuild left behind

Rebuilds after Harvey usually focused on the lower walls, floors and finishes. The attic was often left alone, and insulation that was disturbed by roof or electrical work may be thin or uneven. We measure attic depth, check for gaps around lights and ducts, and confirm that no damp material remains in walls or ceilings.

Garages and shops

Detached garages and metal shops in Dickinson can be foamed on walls and roof to cut heat and stop steel from dripping in humid weather.
