lintel/external brickwork above a window


Postby yorkydale » Fri Mar 09, 2007 2:53 pm

Can anyone give me some advice regarding lintels over windows please?

I am refurbishing a 1930s semi and am replacing the groundfloor lintels no problem ,but i am stuck with regards the upstairs.The exterior brickwork over the window has failed as there is nothing supporting it (although the interior lintel is fine ) what should I do ???? it is bowed and looks like it might fall altogether any minute. I would appreciate some advice about the best way to deal with this. thanks a lot.

The best thing to do would be to support the opening with needles (see the project on forming openings through walls) and insert a proprietary cavity lintel. See the project on cavities and lintels. This will do two jobs by supporting both skins and at the same time makiing sure that any cavity water is thrown towards the outside skin where you leave a couple of vertical joints (perps) clear to act as weep holes for the water. The final thing that doing this job properly achieves is that any future sale is not likely to be stopped because of an incorrect lintel.
