Plastering after DPC

[mhrosoha]

I had a damp survey carried out by Rentokil, a well-reviewed and reputable company. They identified a rising damp issue that needs to be addressed and quoted me for a chemical DPC injection along with re-plastering. While I’m happy to proceed with the DPC injection, I’m wondering whether it’s worth having the re-plastering done by them, as it’s quite expensive and I could get it done cheaper elsewhere.

Rentokil requires the plastering to be done to their specifications (please see attached) for the 30-year guarantee to remain valid. Do you think it’s worth using my own plasterer and saving a significant amount of money, even if it means forfeiting the guarantee? Or would it be better to go with Rentokil for the plastering as well

OP,
You say that the survey was by Rentokil but your specification is by Peter Cox - how come?
1. Why not post pics of the area(s) identified as needing rising damp treatment. Show pics of the interior & the exterior.
2. What kind of damp treatment was recommended to form a DPC?
3. Typically, these companies drill & insert cream or rods claiming that they form chemical DPC's.
4. If you can drill a hole in a mortar bed then you can do this yourself.
5. Best practice for rendering is a mix of 3 x sand and 1 x NH lime - no cement. And Limelite skim finish.
6. Any plasterer can do such simple work.

Same company.
