A mason has just put me some new openings in on a conversion project. The reveals aren't flush as it's natural stone, approx 40mm difference I don't want a huge mastic joint at the side of my aluminium windows/doors.

What's the best method to resolve this? Chisel stone down to right size even though they're insitu? Or chop a channel from the inside so the window frame sits in that?

Any other options would be appreciated.

Cheers,

Hi jam11gee
Suggest you use an angle grinder to cut out a channel the width of your frames and chisel out the centre part. Do a number of cuts down the channel to limit the force of chiselling needed. You may need to fit a narrow sub frame so you can get the windows in.
