Quote for eradicating damp on walls. Big task? Does it work?

This isn't really an is this quote fair question, it's more about the work involved...

In the quote it states:

[FONT=&quot]On our inspection of the above property for rising damp to the lower sections of the ground floor walls, we took high moisture meter reading from the main front wall around the bay window 3.5 Lin Metres and the main rear wall either side of the doorway going into the rear extension 2.0 Metres the damp is being caused by a breakdown in the original damp proof course. We have included our price below for the installation of a chemically injected damp proof course to the walls as detailed above 5.5 Lin Metres of walls in total. This would be carried out using the Sovereign Chemicals system of installation and on completion of the work the treated areas would be covered by a Sovereign Chemicals 30 year guarantee. [/FONT]

Was talking to a few people about this at work & they were saying that injecting this DPC isn't as reliable as you may think - it often fails/simply doesn't work very well.

Is this correct or are they talking BS? Don't want the job to start if it's all a waste of time & money.

Also, does the above sound like a big job to you or is it very minor? We were told there was damp on one wall, but the above quote sounds like 2 walls to me.

I imagine they chip away at the plaster/plasterboard to take it back to the brickwork & then layer it up with some damp proof paint like substance & then plaster/plasterboard over it again?


The above is at £440+VAT.

Suspect BS when anybody mentions rising damp as a matter of course. Yes it happens but its extremely rare. Tony's correct with his list but you should also add:

DPC being bridged by patio or other structure and water splashing up over DPC because ground level has been raised by some sort of works. Ground level should be at least 150mm below DPC.
