A garage and driveway that pull their weight

It usually comes down to what failed and how old the door is. A broken spring, a frayed cable, or a bent track section on an otherwise solid door is a straightforward repair. Widespread rust, cracked or delaminating panels, a door that has been hit by a vehicle, or a decades-old door with no safety reversal system typically argue for replacement, since repairs on a failing door tend to come in a series. Replacement also happens to be one of the better-returning exterior projects in national remodeling-value studies, which changes the math if a sale is on the horizon.

Asphalt's flexibility gives it an edge in severe freeze-thaw climates: it can move slightly with the ground where a rigid slab would crack, and it tolerates de-icing salts that can scale newer concrete. That is why asphalt dominates driveways across the northern United States and Canada. Concrete lasts longer and needs less routine upkeep, and it performs well in cold regions too when the base is properly compacted and drained — base preparation matters more than the surface choice. In hot southern climates the logic flips, since asphalt softens in extreme heat while concrete is unaffected.

Concrete gains strength gradually as it cures, and most installers ask you to keep vehicles off for about seven days, with foot traffic fine after a day or two; the slab continues hardening for weeks after that. New asphalt can typically take cars within two to three days, though it stays soft in hot weather for its first season, so it pays to avoid parking in the same spot daily or turning the wheels while stationary early on. Your installer's guidance controls, since mix, weather, and thickness all shift these windows.

Springs are rated in open-close cycles — often around ten thousand for standard torsion springs — and a family using the garage as its main entrance can use that up in seven to ten years. Cold weather makes brittle springs more likely to let go, which is why so many fail in winter. Replacement is one of the few home repairs that is genuinely dangerous for a capable DIYer: a wound torsion spring stores enough energy to cause serious injury if it slips off the winding bars. This one is worth handing to a technician with the proper tools, and it is standard practice to replace both springs on a two-spring door since the second is usually close behind.

For asphalt, yes — sealing every two to four years slows the oxidation that turns pavement gray and brittle, and filling cracks promptly keeps water out of the base, which is where real structural damage starts. Sealing brand-new asphalt too soon can trap oils and soften it, so most installers suggest waiting through the first several months. For concrete, a penetrating sealer helps resist de-icing salts and freeze-thaw scaling, particularly in the first winters. What sealing cannot do is fix a failing base: if a driveway shows interconnected alligator cracking or sunken areas, sealer is cosmetic and the money is better put toward repair.
