Case Study 10 - Basement Window Cut-Out, Installation
Cut a level hole for the window
Install a supported Lintel.
Marking out the cut.
A self-levelling laser matched the window height with other windows.
Pilot holes were drilled in the corners.
All of this was done under Permit.
Excavated to the weeping tile's gravel bed.
A vertical drain pipe will sit above the weeping tile.
The fill around the vertical pipe includes a layer of gravel, and a thick landscaping cloth.
Cutting the hole
Lined up with pilot holes and double-checked, the hole's sides are cut out.
A wet saw is used. and when working from the inside, a basin made of tarps keeps the watery sludge contained, which is simply wet-vac'ed away.
If the cuts can extend past the edge of the window space, then a larger coring saw can cut the block out in a single piece.
Sometimes a larger coring tool can not be used.
Removal of the concrete
We use a demolition hammer to break out the concrete.
The different tips for the hammer each have a useful purpose in such a job.
Window Space Open, Parged
A steel lintel is installed flush with the outside wall across the top of the window, scewed in, reaching four inches beyond each side.
The sides are parged with a little more than needed.
When the cement is almost set it is sanded down to ensure a good fit with the window.
The window is set with 4" masonry screws, pre-drilled, and caulked.
Framing to Taping
The framing is redone to fit around the window, with cripple, king and jack studs.
The tar paper is replaced, the insulation installed, with 6 m plastic as a vapour barrier.
All the seams and any holes are taped to seal the barrier.
