When a torsion spring snaps in Fox Run or Fox Run West, Northglenn homeowners usually hear a bang and find a door that will not lift. Cold Front Range mornings make aging builder-grade springs fail faster — especially on the heavier insulated two- and three-car doors common in those neighborhoods.
Lion Heart Garage Doors is based nearby in Thornton and runs Northglenn as primary territory. We size replacement springs to the actual door weight, replace worn cables when needed, and test balance before we leave. Same-day spring replacement is often available when schedules allow.
