Window protrudes unevenly

6 years ago

Hi, I have a question about a 5x8 window in my front room. The jamb extension sticks out past the drywall so I would like to remove them and make them a little narrower. The problem is the jamb extension protrudes out more on the left side than the right, by about 1/2 an inch. I can rip the boards on the left and right side to different widths, but what should I do about the top and bottom jambs, they need to be about 1/2 inch narrower at one end than the other. Is there a way to fix this other than reinstalling the window?

Any suggestions would be greatly appreciated. Thank you.

If you use an oscillating tool, you'd better cut it large and belt sand the jambs flush with the wall. Maybe stick a strip of plastic laminate against the wall as a blade jig and stay square to the jamb. Expect a little drywall scuffing, but you've got to have a perfect cut because the cut jamb will have an exposed reveal when the casing is installed.

Either that or build up the back of the casing.

Cut them with an Oscillating tool.

Thanks, that sounds like a good idea. What type of blade would you use, the square or semi-circular?

I’d go square since they can be had with more aggressive teeth typically, plus I buy those in bulk.

Are the jamb extensions nailed on? How are they attached? This may inhibit cutting them while attached. Can you remove them? What is the exterior siding You may find it easier to uninstall the window or remove the jamb extensions, cut and reinstall.

They are nailed on and I could probably cut the nails with an oscillating tool. I think I will try using the oscillating tool to reduce the length of the extension while they are in place, and if that doesn't work, then just re-install. Thanks for the advice.
