About Garage Door Triage
Garage Door Triage is an independent diagnostic and cost reference site for garage door emergencies covering garage door repair, spring replacement, opener troubleshooting, and cost estimation. We build diagnostic and cost calculators and guides that answer one question well: should you attempt a repair yourself, and if so what will it roughly cost?
How our numbers work
Every calculator runs on standard spring sizing formulas and repair cost data sourced from manufacturer specifications and Homewyse surveys. Each formula is checked by hand against worked examples before it ships. Prices on this site are always shown as ranges with an "as of" date, because labor rates and parts prices move with your region and season. We never publish a made-up statistic.
What we are not
We are not a supplier, a contractor, or an engineering service. Our numbers are planning estimates, not job quotes. For anything involving high-tension springs, structural modifications, or safety risks, confirm with a licensed garage door professional before you pick up a wrench.
Corrections
If a number on this site looks wrong, we want to know. Email hello@garagedoortriage.com and we will check it against our sources and fix it quickly. Getting the math right is the whole point of this site.
