You're definitely not the only one....it would be almost as fast to just custom make you own extension jambs. If the window companies would just add an 1/8-3/16 to their extensions life would be easier!

I like to score the DW with a knife in stead of a pencil mark where it gets bad. I just plan on doing some alterations, or whatever it takes. Don't let it get to you.

Our custom mill relieves our casings so the front and back are a little proud of the center to bridge the problem. That helps a lot, but there's always some screwing around anyway.

Relish the moments when the stars align and you get a textbook window to case. They are far and few between and when you get one it's over before you know it.:laughing:

it's dry wall....if I make a mistake I'll mix a batch of durabond or fill with joint compound. New construction, we're trimming with primer on the walls, maybe 1 coat of paint.....at the same time I'll go around and fill all the other wall dings...please don't tell me you guys don't ding walls and don't need touch up on a new build before final coat!!

Butcher the wood casings or cut into and manipulate the drywall??

I might do things a little differently if I'm replacing a window on a plaster wall or wall papered. 9 out of ten times the entire wall is going to get new paint. Cabinet grade trim on old plaster, no touch up...maybe....

There are 100 reasons why the manufactured extensions aren't flush with the finished DW!....I don't want to smash DW if i don't have to but it's the least of all evils IMHO!
