Too Deep Windows

I need to put interior casing on windows that are too deep. They have been installed and new siding put on so removing them is not an option. There is almost an inch too much on the inside. Does anyone have any suggestions on how we can put casing on them without making them look ridiculous.

Hi Rhonda- not following you- what exactly is sticking out- the window frame (with sashes) or the jambs? If there are factory installed jamb extensions sticking out, you should be able to remove them & rip them to the proper size, re-install, then install casings. Maybe you could upload a pic so I could see whats going on.

I should have said that they are pvc windows. I know they should have been cut down before they were installed. I thought that someone might have an idea of how to finish it off with casing. I don't think taking them back out is an option, there are 11 windows in all.

Hi ronda i bet it is about 1/4 inch right and if it is you can by some 1/4 wood at home depot and ad it to the wood area to bring it out Then when you install your trim you could paint it I hope this helps.

No the problem isn't that I have to add on, it is that they stick out too far into the room, by an inch. Now I have to figure out a way to configure it so that casing won't look silly.

Hi Rhonda- the casing is going to look silly if it does not rest against the wall- anything you try to do short of ripping the jamb extensions down (was there a contractor or window supplier involved here?) is going to look like it does not belong.

You could go ahead & case the windows, then rip any material you want (MDF, pine, poplar) to 'back fill' the outer edge of the casing to the wall, but that will limit your final windowcovering choices, and is still not the proper way. Hope this helps.

Another alternative is to buy casing as you normally would and add to the back end (the part not attached to the window but to the wall) the difference you need. The casing will be 'deeper' than traditional but I thinks this will be your easiest option.

Good Luck!

Hi Rhonda if you are using a 2 and 3/8 casing all you have to do is make a sub frame approx 2 inches from the window on the wall, use a 1 inch material width does not matter, than when you put your casing on you nail it to the jam of the window and the frame you put on the wall when you tand to the side it will looked finished, I am not saying this is the right way but it is a way i have had to do in the past and my customer was happy with the result i hope this will help you, thank you Cliff D&C Windows and reno's

my suggestion would be to add strip of wood and wood fill and sand,prime and paint.if its a good job you will not notice the difference.also blindes or shutters will hide the seam if any.
