I'm replacing a wooden window in a single skin brick shed. I've got the replacement unit - fortunately it was an off the shelf size - but the gap around the frame is very small. Should I try and put cement in the gap, or just use frame filler on either side? Is there not a risk of condensation forming in the gap if you fill from both sides, or will the brick breath enough to eliminate this?
Also - when installing the window - do I put a layer of mortar on the bottom of the opening and sit the frame on that (assuming it's level?) I seem to recall reading that the proper way to do this was to wedge the frame up against the head of the opening (again, checking to make sure it's level) and then force mortar in the gap under the frame to hold it up, but I can't find any guides on this. The replacement window is also wood by the way.
Thanks
Chris
