We're not going to put a number here that we can't back up for Poolesville specifically, and we don't have one. What we can tell you is how the decision usually plays out at this income level. Repairing a failing opener - new gear kit, new logic board, a capacitor - makes sense if the unit is under ten years old and otherwise sound. Past that, with the kind of household income this area runs, most owners we talk to decide a full replacement is the better spend rather than nursing a motor that's going to need another part next winter.
That's not a sales pitch, it's just what the numbers tend to do once you're past the point of cheap fixes. If your opener is original to a renovation from fifteen or more years back, ask us to look at the whole unit before you commit to a repair - sometimes the rail and sensors are fine and only the head needs replacing, which costs less than you'd think. For anything involving an exact quote, that gets priced on-site, not here.
