Doors – re-shim the strike side of the door jamb to make a 28″ door fit

doors

My old door was 27 3/4 inches. The new doors are sold in a standard 28" size. Instead of trying to cut a 1/4 inch of the door (I don't have a saw guide) I thought it would be easier to pull the trim off and just redo the strike side of the door. All I need are shims right? And a level πŸ˜‰

Is it better to do this vs cutting it down a 1/4 inch since if anyone wants to replace the door again in the future they won't encounter this problem.

**** UPDATE****

After buying a hand plane for $10 at my local big box hardware store I started plane'ing the door, it was taking a while so out of stupidity I thought I would go ahead and use my Ryobi Circular saw to make the 1/4 inch cut.

This ended up being a miserable failure, the gap ended up being too large, what I really needed was 1/8". Instead of buying a $10 hand plane I would've been better off buying a guide for the saw, but 1/8 of an inch is still hard to cut.

Today I won for worst DIY mistake on 12/18/14. I'm no amateur, I remodeled an entire bathroom ripped up tile and put in new tile, new drywall, lights, and switches. I write all this so that anyone else who has an old house where the door size is off the standard please don't make the same mistake I did, just get a prehung door. If you have a modern house (maybe build within the last 20yrs) you can probably get something off the shelf and put it in without hassle.

Depends on how big of a gap that you have that is currently being shimmed but yes this would be the easiest thing to do. I would make sure that you have at least 3/16" gap at all points before doing this.

Note: Just to be clear you should be using the new jams in this door. At the very least you need to use the hinge side but preferably both. After you take out old jams (top can stay if it is going to cause a ton of work - and most of the time it doesn't) you install put the new ones in.
