If you would like to be considered for this job, please provide an estimate to tune my stuck sliders by using the adjustment screws only. If that fails to solve the problem, then I will need to go back to the drawing board.

I have three sliders in my apartment that need maintenance. The requirement is to get them sliding. They are all floor-to-ceiling, about 8 feet tall, and 37 inches wide. The small door is 32 inches wide, and slides pretty well. The large doors barely slide at all. Their lock is stuck too, of course. The south slider is so far out of alignment that it is almost touching the side of the track:

Here is what half of the balcony looks like from the outside:

I am assuming that the locks will come back into alignment just as soon as the doors do.

This job is in Miami Beach.
