Call 16783903757 and tell us your address, roughly how old the house or door is if you know it, and what the door is doing - won't open, opens crooked, makes a bang and stops, opener runs but door doesn't move. That's usually enough for us to tell you if it sounds like a same-visit fix or something that needs a look first.
For anything past a straightforward spring or cable job, we come out, look at the track, the springs, the opener, and the panel condition, and give you a written number before we touch anything. You're not committed to that number until you say go.
If parts need ordering, we tell you at that point, not after the job's half done. We'd rather give you a real timeline than a fast one that's wrong.
