Damp and external render making good instead of replacing

Postby Jayrb07 » Tue Jan 19, 2021 12:11 pm

Hi all,

Really hoping someone can provide some advice based on experience!

We have just had our survey completed on a property. The house is a proper fixer upper so we knew the inside would need to be gutted and some external work would need to be done.

There is damp in the property, not to the point where it stinks but wall paper and plaster decay is visible on the external facing walls and around chimney breasts. We know the chimney flashing will need attention, some roof tiles and guttering looked at.

The mains issue and one that has been estimated as one of the highest costs externally is the rendering.

The survey has come back and said the external rendering should be completely replaced with breathable lime rendering to avoid water making its way in. Then damp proofing and improved subfloor ventilation work should be carried out.

My question is, can any rendering on the outside be made good with out replacing it all to make it weather proof, with the intention of replacing the rendering in years to come? We know that the damp proof will need to be done internally, but the high initial cost of fully re rendering could be a problem.

Thanks in advance
