Keller's housing sits mostly in the 1980s-through-2010s range, and the area median year built lands around 1999 - newer than a lot of the towns this company covers, older than the newest subdivisions further out. That means most doors we're pulling out are single-layer steel with builder-grade torsion hardware sized for a lighter panel, not the heavier insulated doors homeowners often want now. Median household income in Keller runs well above the wider service area's figure, which we mention only because it changes what people ask for: insulated steel, glass-panel inserts, quieter belt-drive openers, not the cheapest door on the lot. The climate here is moderate heat, not extreme, so we're not fighting warped panels from heat cycling the way we would in a harsher band - the driver for replacement is age and looks, not weather damage.
