We don't post a price list, because garage door jobs aren't uniform. A cable that jumped the drum on a single door is a different job than a torsion spring system on a double door with 25 years of rust on the shaft, and quoting either one blind over the phone would be a guess.
What we can tell you is what you are actually paying for: diagnosis time, the part itself, and the labor to put it in correctly and safely test it. Torsion springs are under real tension, and we don't cut corners setting them.
If a job needs a part we don't carry on the truck, we say so up front rather than guessing at a number over the phone, and we get you a time frame instead of leaving you to wonder. Your house's age matters here more than anything on a rate sheet.
Given how much of the housing stock here is original to construction in the 1960s and 70s, we often find the opener and the door were never meant to work together, which changes what the honest fix looks like and what it ends up costing.
