Cost to replace 1970s bungalow steel window lintels

chaotic_j

Hi,

We have a 1970s bungalow, the gable end seems to have an issue with the original steel window lintels having rusted.

One window has a gap in the pointing of about 12mm where the bricks have raised all the way along.

The other window has a door as well so a bigger span, gap in pointing at sides, bricks look slightly sagged in the middle, all top double glazed units have failed, unsure if related.

Is this really serious? How much would you expect it to cost for this to be rectified? We are in the North-West.

The images show a good example of "rust jacking" - This is where the steel has rusted and expanded causing the bricks to be lifted up. The cost to repair is difficult to gauge. It would depend on the type of lintel fitted and how much work needs to be done internally (i.e. replastering).

Budget £1K to £2K per lintel, and you shouldn't be too far off. At least being a bungalow, you shouldn't have any scaffolding to pay for, so that will keep the costs down.

You will need to have the work signed off by Building Control (don't let a builder tell you otherwise), but the work won't need a planning application.

If they are angle irons the job will be a bit easier. There used to be a metal lintel made by Dorman Long before Catnics became popular in the 70's. It sat on top of the inner concrete lintel and came down through the cavity to form a tray and then over the frame taking the external skin. This type requires a bit more work.
