Garage door questions, answered for Dupo

Yes. Dupo is one of the communities of St. Clair County, Illinois, and we work the whole footprint: Dupo plus nearby Columbia, Cahokia Heights, Millstadt, and East St. Louis. Same licensed, insured crews and 10-year workmanship guarantee county-wide.

Dupo runs a mixed-age housing stock (median build year 1969), roughly 54% pre-1980, so we see both first-generation doors and aging replacements.

Dupo sits in four distinct seasons of muggy summers and freezing, snowy winters, with wide annual temperature extremes. That is hard on a door — winter snow and ice load on doors and tracks, spring damp that rusts unsealed cables and brackets, and humid summers that seize hinges and rollers all accelerate wear on springs, seals, and openers, so the failures we see most here are warped or sagging panels after years of freeze-thaw, cold-snapped torsion springs in deep winter, loosened hardware from wide seasonal swings, and doors frozen to the slab on cold mornings. We size springs and seals for Illinois's continental-climate region conditions rather than a generic catalog spec.

The call we get most in Dupo is warped or sagging panels after years of freeze-thaw. Dupo has mainly suburban houses with attached two-car garages, mixed with some older central-neighborhood homes, so cold-snapped torsion springs in deep winter turns up often too. We carry the common parts on the truck for a single-visit fix.
