Hi all, glad I've found this discussion which confirms to me yes it's a very mixed bag out there! We commence soon on a timber frame passivhaus project and need to make some decisions on windows/doors. Seems to be plenty of experience here and wondering if anyone can narrow down which suppliers/manufacturers offer supply and install please to high standards, which in theory de-risks things. Have been trawling around websites and straightforward info rarely obvious. (i wouldn't place two orders for separate supply and install). And with sensible payment terms.
Currently only spoken to one (no names!) at early stages including a quotation. On paper seemed a very likely choice and i don't doubt the quality (albeit not checked further as yet) but having spoken further with them they insist on unreasonable payment terms wanting the whole lot before anything installed, which in my book is completely unreasonable as leaves nothing on the table as a lever if they get anything wrong - which the chap I was talking to said was not possible, and that if there were any errors it would be the timber frame company! Arrogant?
many thanks
