For a torsion spring that's reached the end of its cycle life, we replace it with a properly matched spring for your door's weight and track length - guessing on spring size is how you get a door that slams down or won't stay open. On the opener side, if the board is original to a 1999-era install, we'll tell you straight whether a repair makes sense or whether the unit's simply done; parts for boards that old aren't always stocked, and we're not going to have you wait weeks for a part when a new opener costs less than the wait. Cable and roller work is straightforward on this door style - steel rollers on steel track, nothing exotic. We true up the track, replace worn rollers, and reset cable tension so the door travels straight instead of binding partway through the cycle. We travel from Arlington to reach Keller, so we schedule the trip once we know what your door needs rather than sending someone out to guess.
