Hi. I have made an error measuring my for a replacement window. It has come and it is 10 cm too tall. I don't fancy paying out for another window. So I was thinking about cutting part of the sandstone sill to fit the window in. Sill is 13 cm high. I considered taking 5 or 6 cm of sill and may be 4 or 5cm off of the sandstone lintel. Lintel is 25 cm high with a span of 74cm. Any ideas on this proposal. Or would it weaken the lintel too much. Window is on gable end at back and is only supporting the few bricks above it along with the roof androof purlin. Any advise welcome.

A bodge and will likely look naff.
Take the pane :mrgreen: and remember next time to measure properly.

If you are really set on this then remove the brickwork and move the lintel to suit. Prob cheaper to re-order though.
 
The Cill and Lintel have already outlasted at least 1 window and will probably do so again, don't butcher them because of a mistake.

This.

Can you not plane 5mm of the frame?

Can you not lower the sandstone cill, 100mm is a lot to lose. One other solution is to take window back and get it cut down but that depends on openers etc and then get glass re made.
 
For the love of Christ, get a new window, or......

..... remove the stone sill and a couple of courses of bricks, lay a split and re-instate the sill with your big window.
 
In all fairness i had to re-read thinking it was 10mm mesel. :rolleyes:

But i did get the gist once i read thoroughly.
 
Could you remove the head of the new window frame, cut down the jambs by 10cm and replace the head - reorder glass to suit the new window size?

If you are patient you may be able to get rid of it to someone looking to do a cut in, but you wont get as much as you paid for it. May be worth asking the mfr if they can help in some way.
