Costs, comparisons and troubleshooting — what to know before you call.
- Torsion vs. Extension Garage Door Springs: How to Tell Them Apart and Which Is BetterTorsion springs mount on a metal shaft above the door and last longer and run smoother, while extension springs stretch along the tracks on each side and cost less up front; both do the same job of counterbalancing the door's weight, and both are under enough tension to injure you if handled wrong.
- Repair vs. Replace a Garage Door: How to DecideRepair when a single part has failed on an otherwise sound, reasonably young door; replace when the door is 15–20+ years old, structurally damaged, or the repair would cost more than about half the price of a new door.
- Insulated vs. Non-Insulated Garage Doors: Which Is Worth It?An insulated door is worth the extra $400–$800 if your garage is attached, conditioned, or used as a workspace; a non-insulated door is the sensible, cheaper choice for a detached garage you only park in.
- Belt vs. Chain vs. Screw Drive Garage Door Openers: How to ChooseChoose a belt drive for a quiet attached garage, a chain drive for the lowest price on a detached garage, and a screw drive only if you want few moving parts and live in a mild, stable climate.
