We work out of Whittier, about 6 miles from La Puente, and that trip is part of the job, not an extra. We don't keep a branch or a depot in La Puente itself, so when you call, you're booking a truck that's driving in, not a crew already down the block. Tell us the symptom as plainly as you can - which side drags, whether it's quiet or grinding, whether the opener runs but the door doesn't move - and we'll bring the hardware that fits a door of this age rather than a generic kit.
If you're not sure how old your door is versus the house, the house year is usually the better guide here, since so much of La Puente's stock dates to the same narrow build window. That's enough for us to load the right spring type before we leave the shop.
