Dewar sits just north of Okmulgee along Highway 75 with a mix of mid-century frame homes and some newer modular builds on smaller lots. Many of these houses have open attics and uninsulated crawlspaces that let summer heat and moisture drive up cooling costs. Our crew from 1509 S Wood Dr brings the rig straight up Highway 75 to seal those voids with closed-cell foam that also adds structural strength to older joists.
Access in Dewar often means working around narrow driveways and mature trees near Dewar Public Schools. We stage equipment on the street side and run short hose runs to keep disruption low for neighbors. The same humid subtropical pattern that brings heavy summer storms also creates condensation risks in vented attics, so we match foam density and vapor control to each Dewar address rather than using one formula for the whole county.

Okmulgee Spray Foam Insulation in Dewar — Local Notes
- •Dewar housing stock from the 1950s-1970s commonly has R-11 or less in attics; closed-cell spray foam brings it to code while sealing the many roof leaks that show up after Oklahoma storms.
- •Smaller lots off Main Street limit truck positioning, so we use compact proportioners and extended hoses to reach crawlspaces without blocking residential access.
- •Dewar sits on clay-heavy soils that hold moisture after rains; open-cell foam in attics paired with sealed rim joists prevents the mold that appears when humid air meets cooler ductwork.
- •Winter lows still drop enough to cause pipe bursts in uninsulated Dewar crawlspaces; a 2-inch closed-cell layer adds both insulation and a continuous air barrier right at the rim board.
