Lots - because the header over the doors is almost always separate for each door, you have to temporarily support the front of the garage and the overhead floor/attic joists, tear out both doors and their headers, commonly cut further up into the wall to fit the larger / longer single-door header in, then put in new header and new wider door and new heavier-duty opener.

You can find a couple of previous similar questions about this in the Home > Garage Door link in Browse Projects, at lower left - but would be real rare to get for less than probably $2500-3000 or so, and commonly more - especially if there is an additional story above the garage or if the wall is not standard stud framed.


If you mean to just block off one door so it cannot be used and does not let heat escape, commonly you can do that with a temporary insulated wall within the existing frame just using a 2x2 or 2x4 wall with plywood on inside and siding or plywood on outside - preferably made with bolt-in construction and access points to remove the bolts (or at least "cut here to remove" marks) so it can easily be taken out come house sale time to restore the second doorway. More like $700-1000 range for a very simple approach to that, assuming it can be fitted in front of the existing garage door. While you could remove the garage door if you wanted, commonly it is left in place for easier return to functionality come house sale time.

Note if blocking off one door AND also isolating that garage with a wall between the two bays, will likely require a door through the dividing wall or an outside egress door - or possibly outside egress door plus emergency egress legal window, depending on your code requirements and whether the second bay is going to have sleeping facilities in it.

Depending on construction and what you are doing, Carpenter - Framing or Remodeling - General Contractor or possibly Garage Door companies would be your Search the List categories to find well-rated and reviewed contractors to bid this job.
