Damp Proofing - pre-work advice

tobya

I am going to be having some DPC work in about a month's time and am wondering whether anyone who's had this done before could give me some advice on what to expect, in terms of disruption, and what to check to ensure that the company that is going to do the work, Proten, does a good job?

Should I be thinking about putting electrical goods and other furniture into store before work begins and what else should I consider (dust-sheets, sealing doors) to reduce the chances of collateral damage?

Thanks in advance for any advice.

Tobya,

Is it the, drill holes in brickwork and inject silicon (other other suchsolution) into holes type DPC?

I had it done recently and it does work (not by this company) but they mademe remove all plaster on inside of house directly bonded on the injected wallsto a height of 1.2m above injection line. would not guarantee work otherwise.you then have to re-plaster with a suitable waterproof plaster.

They said if I didn't do this all the salts/minerals from previous dampwould remain in wall and cause issues in the future. Hence they wouldn't guaranteework unless this was done.

Who diagnosed failure of the damp course and what were the symptoms? If the company doing the work diagnosed it, then be wary, as there appers to be a history of misdiagnosis in order to get expensive 'corrective' work.

What you should expect, and specify it as a condition of the contract is that the company provides and uses all necessary dust sheets and protective covers over all your carpets, furniture and goods.

It may well be that you are expected to move stuff to allow access to the walls, but then everything should be covered by them before anything else is even done. And at the end of each day, everything is tidied up and vacuumed and cleaned down. No sheets, no vacuum, no brush ... no start. Tell them this before they even get to site

You need to ensure that you get a 20/30 year insurance backed guarantee

But above all, firstly you need to be sure that you actually have a rising damp problem instead of any other sort of dampness, and that the system used is appropriate for the dealing with the problem you have
