Damp Proofing

What is the rough cost of a dpc for 23m of wall? the house is a victorian end of terrace. please include the cost of replastering internal walls.

The 1860s house I'm considering making an offer on has damp in both the main part of the house and the 1980s extension, so I assume the DPC has been breached.

I'd like to know the rough cost of redoing the DPC. At the moment, the DPC in the extension is just 1 inch from ground level and the render begins just about this, so I assume some render might need to be removed. If this is likely, it would be great if you could also factor this in to the cost.

The house does not require a dpc as there is no such thing as rising damp. Please seek out Peter Ward online at heritage house.
The house will be damp because of raised ground levels, blocked under floor vents, poor guttering, poor drainage, incorrectly installed concrete floors, poor ventilation from double glazing, modern gypsum plaster, plasterboard, cement render, cement pointing, roof insulation rammed into the eaves ventilation.
Your surveyor does not know what they are talking about.
Solid wall houses must not be prevented from breathing by using modern materials.
If you still want to waste your money on useless damp treaments that will do more harm than good that is your prerogative. Please refer your mortgage company to BS7913, part of the building regs, or professor John Edwards of the CIOB.

Hi there,
If you work on £50 per metre, to include replastering you will not be far out.

Rising damp is most definitely something that affects many houses. However it is impossible to diagnose how damp is permeating the building or to price the remedial work required without a comprehensive inspection. Installing a DPC may not be the only form of damp proofing needed, as penetrating damp could be causing problems above the DPC. I would strongly suggest having a structural survey with a view to finding the sources of damp in particular, then a better guideline price for remedial works could be gleaned from the surveyor’s report along with a visual inspection if possible.
