Pebble dashed walls and cavity fill insulation

Wyldwood

25 year old house has that dashing on outside walls where there are gold/brown coloured chippings thrown into the plaster, dry dash I think?? - question is walls need insulation upgrade, cavity already has minimal polystyrene boards that were the regs in 1980s, but how do we fill with that finish on walls. Drilling holes will make a major mess of the dashing. Don't want drylining for various reasons.Has anyone had these type walls retrofilled or maybe there's an insulation installer on here with ideas.

Better off in the C & P forum. Moved

I visited a house recently that had the cavity walls pumped. It had pebble dash like you described. The contractor who did the insulation filled the holes with sand / cement which was a colour close to the plaster work and then pushed stones similar to the dash into the sand cement, it looked a great job and was difficult to see exactly where the holes were drilled.

Thanks for that he wouldn't be in the Munster region by any chance would he?

I've seen been done on a couple of pebble-dashed houses and the patched holes are probably even less noticable than on a smoothwall finish as the it's harder to see the patches betwwen all the pebble-dash. It is important that they get the colour right though.

The house I visited was not in Munster, but there are numerous contractors which would carry out the work in Munster,
I just went on to the SEI website there and there are 107 contractors available to carry out the works in Munster.

There is indeed but it cant be obtained as a stand alone grant as the minimum grant payment has to be €500 (open to correction on the figure). Walls + attic insulation would cover it.
