Spray Foam Insulation in Bethany, OK

Spray Foam Insulation in Bethany often starts with an older house. Bethany was founded in 1909 as a community for members of the Church of the Nazarene and incorporated in 1910, per Wikipedia. It stayed small until the 1940s, then grew from 5,705 people in 1950 to 12,342 in 1960 and 22,694 in 1970. Since then the population has held near 20,000, so most of its 8,850 housing units are from the middle of the last century.

What we find in Bethany attics

Mid-century homes here often have a few inches of settled fill, old ductwork with taped joints that have let go, and open gaps around chimneys and plumbing. Air sealing those, sealing the ducts and blowing fill to depth is the most common job. Where the attic is shallow or the house has an addition with a low roof, spray foam may be used in those sections.

A rental-heavy town

Wikipedia reports that 46.2 percent of occupied homes in Bethany were renter-occupied in 2020, partly because of the university. Landlords often want quick, non-disruptive improvements, and attic work fits that.

Storm history

Bethany knows storms. An F4 tornado on November 19, 1930 destroyed 652 buildings, and the city sits on the west side of a metro in Tornado Alley. After any roof repair, check the insulation for water damage.

Near Lake Overholser

Wikipedia notes that Bethany is bounded on the west by Lake Overholser and the Stinchcomb Wildlife Refuge. Homes on the west side sit near the water and the river bottom, and some have more humidity in the attic or around the foundation. When we see signs of moisture, such as rusted nails, stained decking or a musty smell, we look for the cause before insulating. Often it is a bath fan venting into the attic or a dryer vent that has come apart, both easy to correct.

Additions and conversions

Many Bethany houses have been expanded over the years with a back room, a converted garage or an enclosed porch. Those spaces often have different ceiling heights and roof slopes, and some were never insulated well. Foam fits those spots when loose fill cannot reach.
