How many years until the spring reaches its rated cycles?
This is one line of arithmetic: the spring's rated cycles, divided by the cycles the door runs in a year. It tells you how long the rating would last at your pace of use. It does not predict when a spring will break, and we have no source for how long a spring lasts in any climate. If your door has one, read the rating from the spring's tag or the door's paperwork.
Answer the questions
Or type your own numbers
One cycle is one full open and one full close. A trip out and back usually means two cycles. Spring makers may count differently, so check your paperwork.
The arithmetic is one line: years = rated_cycles / (cycles_per_day x 365).

The result above appears when scripts are on. Each result below is listed with the answers that lead to it, in the order the tool checks them.
About 13.7 years at 2 cycles a day
Chosen when: How many times does the door open and close on a normal day: 2 cycles a day; What is the spring's rated number of cycles: 10,000 cycles
10,000 divided by (2 x 365) is about 13.7. At 2 cycles a day, a spring rated for 10,000 cycles reaches its rating in about 13.7 years. That is arithmetic, not a prediction: it does not say when a spring will fail, and we hold no source on how long springs last in any climate. DASMA says spring systems "are dangerous and should be repaired only by trained professionals" and that older doors should have their springs inspected by a professional technician. If the door has two springs and one breaks, DASMA says to replace both.

Find the rating first
Chosen when: What is the spring's rated number of cycles: I do not know
The calculation needs the spring's rated cycles, and we cannot supply it: we hold no source for what ratings springs carry. Look for a tag or label on the spring, the door's paperwork or the original quote, or ask the company that installed the door. Ask a trained technician to read it on a visit rather than handling the spring yourself. DASMA says spring systems "are dangerous and should be repaired only by trained professionals."

Use the formula
Chosen when: How many times does the door open and close on a normal day: Something else
Divide the spring's rated cycles by the number of cycles the door runs each day times 365. For example, 25,000 divided by (3 x 365) is about 22.8 years at three cycles a day. It is arithmetic, not a prediction, and a trained technician should handle anything to do with the springs themselves, as DASMA says.

Rated cycles are a maker's figure for a spring, not a promise about your door, and we hold no source on spring life in any climate. DASMA's cold-climate technical sheet says doors in climates subject to extreme heat or cold should be kept closed where possible and lubricated per the manufacturer's instructions; it does not give a spring life figure. The preset numbers on this page are examples only.

Request sent
We passed your job request to one garage door company serving your area. Keep your phone nearby.
- 1The company calls or texts from its own number, which may not look familiar, and we do not control when. If you have heard nothing after one business day, treat the request as unmatched and use the guides below.
- 2Before you agree to any work, ask what license or registration the company holds, if any, and check the number with the agency that issued it. Ask what the call-out fee covers and get the price in writing.
- 3Reply STOP to any text to end texts. To stop us sharing your details, use the Do Not Sell or Share page.
Until the company arrives, keep people, pets and vehicles clear of the door and do not try to lift or force it. The federal rule for door openers says: "Weak or broken springs may allow the door to fall rapidly, causing injury or death."
- Keep everyone and the car away from the door.
- Photograph the spring and the opener label, if you can do it from a safe distance.
- Note the door's width, and whether it is insulated.
- Clear the floor under and around the door so the technician can work.
- Write down what you saw and heard, and when it started.
