Identify what your door is doing before you call. If it is one of these, do not keep operating it.
Your torsion spring has snapped under intense torsional load. Forcing the opener to lift the door without spring assistance will burn out the motor or snap the drive belt.
A stripped internal nylon drive gear or a blown starting capacitor. We carry complete carriage gear rebuild kits in our trucks to repair your system immediately.
Don't let a snapped spring, snapped cable, ripped weather seal, or a defective remote keep you locked inside. Our expert teams carry fully stocked dispatch trucks. We regularly perform comprehensive garage door maintenance (inspection, lubrication, adjustment, and component testing) to keep your system safe. We serve San Marino and the cities around it.
3,061 of San Marino's 4,363 homes were finished in 1949 or earlier, and the census will split that block for you — 1,771 of them sit in the row for 1939 and anything before, against 1,290 from the 1940s, 481 apart with 414 printed as the margin on that difference. The median build year is 1943 and 93.6% of the stock was standing before 1980. That is where the work starts, because that is where the load is: springs, lift cables, drums and bottom brackets sit under the door's weight until somebody takes it out deliberately.
The counterbalance rules for a door system of this kind are written down in ANSI/DASMA 103, and the edition behind them is dated 2017 — seventy-four years after the middle of this housing was finished. It is a voluntary specification and not a law: it binds a door system that claims to comply with it, and it says nothing at all about what is already hanging in anybody's garage. What it asks for, at its plainest, is that a counterbalance spring or weight be restrained.
So on a street this old it is not a compliance question. It is a short list of things worth looking for. On an extension-spring door — something you see rather than deduce — the restraint the standard asks for is the containment cable, which DASMA's glossary defines as “a cable threaded through an extension spring to retain the spring if it breaks”. Whether there is one is visible from the middle of the floor, and it is worth looking before anything under tension gets a wrench on it. Everything else is sized to the door in the opening, which is why a quote here comes off a measurement rather than off the year on the table.
