I'm looking for an experienced handyman to inspect and repair 2 sliding doors that is difficult to open and close. The door becomes particularly hard to slide during colder weather, while it moves slightly better on warmer days. However, it is still not sliding as smoothly as it should. I'd like someone to inspect the door, identify the underlying issue (possibly worn rollers, track problems or misalignment) and carry out the necessary repairs to get it sliding smoothly again.
