Signs your spring is failing

Any one of these means the spring needs replacing. A door stuck open with a broken spring is an emergency repair.

  • A loud bang from the garage, often when nobody is using the door.
  • The door won't open, or the opener lifts it only a few inches and stops.
  • A gap of an inch or two in the coil of the spring above the door.
  • The door rises crooked, with one side higher than the other.
  • With the opener released, the door feels very heavy to lift by hand.

We strongly recommend professional replacement for all spring work. Our technicians perform spring replacements daily and carry the correct springs for most residential doors in our service vehicles. A typical spring replacement in Pacifica takes about 45 minutes to an hour and comes with a warranty on both parts and labor.

If you're seeing any of the five signs above, don't wait for a full failure. Call (650) 777-8776 for a same-day spring assessment and replacement.

Coastal hardware

Torsion springs in salt air and fog

Why it fails here
Salt carried in the fog settles on bare steel coils and the bearing plates. Rust adds friction between the coils and shortens a spring's cycle life. Source: ISO 9223:2012, Corrosion of metals and alloys: corrosivity of atmospheres.
What holds up
Galvanized or oil-coated springs rated for more cycles, and sealed end bearings. They cost more at the start and stand up to salt air longer.
Spring life
A regular-duty torsion spring carries an estimated life of 10,000 cycles. One cycle is one opening and one closing of the door. Source: Prime-Line regular-duty garage door torsion spring product specification.

Spring questions

How much does garage door spring replacement cost?

One extension spring starts from $150, one torsion spring from $200 and both torsion springs from $320. Door weight and size can raise the price. You hear the exact price before any work starts.

How long do garage door springs last on the coast?

Springs are rated in cycles, not years: a regular-duty torsion spring carries an estimated life of 10,000 cycles. One cycle is one opening and one closing of the door. A door opened and closed twice a day makes about 730 cycles a year. Rust from salt air adds friction, so a coastal spring can reach its limit sooner. High-cycle and galvanized springs are the longer-lasting option.

Can I replace a garage door spring myself?

It isn't a safe job to do yourself. A torsion spring stores enough energy to lift the whole door, and winding bars slip. Leave the door closed, keep the opener unplugged and call for the replacement.

Call (650) 777-8776.

If one torsion spring breaks, should I replace both?

On a two-spring door, both springs went in together and have made the same number of cycles, so the second one is usually near the end of its life too. One torsion spring starts from $200 and the pair starts from $320, which costs less than a second visit later. You choose on the visit.

How long does garage door spring replacement take?

On a standard home door, a spring replacement and the balance test after it are normally finished in one visit. A heavy or oversized door, a pair of springs, or worn cables found at the same time can add time.

Spring snapped? Leave the door closed.
