Call 17173269660 and tell us what the door is doing - won't open, won't close, makes a bang, came off track, opener runs but the door doesn't move. That's enough for us to get a rough idea and get someone out. For a number that actually holds once we're there, a few things help: the door's rough age (even 'the house was built in the 70s and it looks original' is useful), whether it's a single or double door, whether the opener is original or replaced, and whether the spring is on top of the door (torsion) or along the sides (extension). If you can send a photo of the broken part, even better. We work out of 700 Indian Springs Dr, Lancaster, PA 17601. With 103,156 households and 40,693 owner-occupied houses across the area we cover, we see a lot of variation in setups even within the same neighborhood, so a phone estimate is a starting point, not a final number. You can also see more about what we cover on our homepage.
