cutting plaster and brick indoors ?

[2ptjoe]

I've got a new extension which i can now open up into the old house , and to do this i've got to cut through the existing brickwork and plaster. For obvious reasons i need a nice straight edge to make good eventually so i want to cut the brickwork.
Whats the best way of doing this without the bedrooms and bathroom looking like they've been in a dust storm ?

Thanks

You'll need a lintel or two over the doorway.
You can hire stone saws but they can make one hell of a mess.
To make the hole, you need to mark it out first, then I would you a bolster chisel and hammer to remove the plaster on the marked area.
The next thing to do is.
Using an SDS drill and masonry bit to drill a few holes, through the brick work, with the holes in line.
Spaced out about every 40-50mm, again bolster chisel and hammer to break the brick.
But get the lintels in place first.

Thanks for that. The only bit i didn't say was part of the wall is a window , i'm taking out the brickwork under the window, so the lintel is already in place above the old window.

Thanks for that.

No worries, good luck with the job!

Do the bedrooms and bathroom open on to the extension with no doors? If not close the doors and seal around with masking tape. If your extension opens into a single room seal the door before you start. That way you only finish with dust in one room. I have just installed a new window in a block built outside wall using this method, when the hole was finished we cleaned up through the hole, hoovered, let the dust settle, then hoovered again. Then fitted the new window and unsealed the door. All clean and no problem. You will need a good dust mask and safety goggles.
