Hi I'm Emma,
I'm a home owner.
Also a total novice with plastering and rendering. Only ever had interior walls skimmed and never had any issues re that in the past.
But we're having external wall insulation installed at present, on an old council house, it's originally concrete and render construction (no brick.)
We've had a catalogue of issues with the company doing this work so far (some of it reasonably trivial admittedly) ;-
Initially they almost smashed a window dropping large chunks of concrete off the scaffolding from roof height.
Left rubbish strewn across my lawn (for so long it killed it) and garden, front and back - for well over a month, had to complain to the company director to get them to remove it in the end.
Applying base coat before protecting any windows/doors - they were contractually obliged to protect them before starting (have had to chisel off render from inside a window frame) also this was done in temps below 4dc.
Repeatedly removing and leaving detached the bathroom waste pipe.
Not fitting or trimming the polystyrene bricks to allow enough space on the window reveals - by this I mean my top opening windows have very little clearance (less than 1cm) from the base coat to the window opening itself, so windows will potentially not open/catch the dash once the dash receiver and dash is applied inside the window reveals, depending on depth. (One workman said dash receiver and dash depth will be around 1cm, then another has said it will be 2mm..)
Could someone just confirm for me what the average or recommended depth of dash receiver render, then the dash ontop should come too?
They are using Johnstone's high performance dash receiver - not sure if different brands have differing recommendations on depth/temp.
And also they are applying these (dash receiver/dash) in rain and it is forecast to rain heavily later today and every day this week, is that good practice? I'm worried a 'wash out' may occur. Company director has said this morning when I queried it, that its perfect weather to do this in. Is that true?
Can also see the plastic corner beads through the dash receiver and dash on the areas they have completed, should that be visible?
Its costing over 11k, so I'm really concerned they are cowboys and doing things by halves.
Would very much appreciate some advise,
hopfully I'm just worrying needlessly!
Thanks for taking the time to read this
