Hello. My name is Adam. My experience with carpentry is limited. However, I've been hired to install door and window trim in a house that's being sold in Michigan's Upper Peninsula. I'm familiar and comfortable with the tools necessary to finish the job. The process itself, however, is a bit foreign to me. I've watched a film, scanned through a book. I'm eager to take on the job.
The problem I'm running into is that the window jambs are not flush with the surrounding drywall. I would use jamb extenders to correct this problem but the gap between the jamb and the drywall is not uniform around the window. At the top of the window, the drywall is proud of the jamb 3/8". Once you follow the side jambs down, however, the bottom is flush with the drywall and would require no jamb extenders.
The person that's hired me to complete the work has suggested running a jamb extender around the window to compensate for the greatest gap (3/8"). At the bottom, then, there would be a 3/8" gap between the trim and the wall behind it. He intends to caulk this cap and paint over it. I think the resulting gap may be too large to caulk.
Please reply with any thoughts or suggestions you may have. One other possible solution is to reset the placement of the window itself in order to bring the jambs flush with the drywall. This may be more work than it's worth as the house isn't in the best of shape to begin with and the sellers are only interested in getting it on the market as soon as possible.
Thank you very much for your time and consideration. I appreciate the database of information that this website provides.
