Replacing a lintel

Lorrainemck2

Hi folks I need some advice bought a house in march terraced built 1940's. The sandstone lintel has quite a big crack and as a result we are getting a lot if damp in the bad weather.
Had a builder out today who advised one sand stone is very porous, and when the double grazing was fitted more than likely not the correct lintel or cavity tray fitted, so will need that all fitted and brick work replaced on the lintel also. One big window at front of house and a smaller window next to it. Any ideas what I should expect cost wise, l live in the north east??? Builder getting back to me with a quote tomorrow evening.

Excercise caution before going ahead with the work. Your builder may be spot on, but your description of the work does not add up.

Why does a cracked sandstone lintel cause damp penetration? A 1940 era house is likely to have cavity walls, and the lintel is on the inner leaf or the outer leaf?

Are you saying you have a new structural opening for the double glazing? Why has the lack of a cavity tray only just come to light?

Before getting any work done you need to be sure on exactly what the problem is. Only then can a resolution be proposed. Then you can consider if the price is reasonable. At present I cannot advise because I do not understand the problem. I suspect that others have not replied because they too cannot fathom out the problem.

Perhaps you could post some photos. Then you may get others to contribute some ideas.

Hope this helps.

It would be unusual to have to put in or replace a Lintol when having replacement double glazing installed.

You need to exercise caution as a Lintol is a structural element of the wall. It will need to be removed carefully and proper propping will need to be undertaken before it is removed.

You may also need to inform your local building control dept as this is structural work.

Be careful. As previously suggested a bit more detail is needed before any more specific comments can be considered.
