Out of curiosity, S.O.S or Pot Noodle, what’s the industry norm cost to build a large segment-headed two-over-two sash window from scratch? Obviously I don’t want to start WWlll here, but a ballpark figure would be much appreciated.

(apologies, not looking for work at the minute)

And perhaps to steer things to a more constructive end, what sort of challenges are you facing in terms of energy conservation versus authentic design considerations? Particularly in relation to double glazing, but also Low-E glass etc. How have you found local authorities in their attitudes towards preserving the integrity of windows of Protected Structures you’ve worked on? Do they give a toss over detailing? How do you advise your clients that insist on an insulation gain with their reproduction sashes over first generation PVC they’re replacing?

It’d be most interesting to hear your thoughts on these matters given you’re at the coal face.

When you take out a large window surround, being at a coal face would be less dusty.:D

It is very hard to give exact prices because different people and jobs require different things.

If for example someone wanted to keep the glazing bars to the proper 19mm then it has to single glaze but if they want double glaze then the bars have to increase to around about 30mm or be 1 over 1 or to have those god awful white bars between the panes.

I’m in the process of building some double-glazed corded sash windows 1 over 1 with curved tops that cost €2250 each fully finished and installed.

On the other hand I have done square 2 over 2 single glazed windows for €1700.(3mm drawn glass).

Double glazing:-I use Pinkingtons low-e glass when asked to use double glazing.

I deal mainly with private customers and in any case always steer my clients matching original details, I just don’t see any reason why I shouldn’t.

Regarding the insulation of heat as we all know most of the heat lost from old houses is through the walls and ceilings.

Once the draught-proofing is in an old sash window it makes the whole house warmer.

BER ratings reflect this.

Speaking for myself I advise my customers when they have me in their house to get their front and back door draught proofed at the same time.

I think the local authorities generally speaking are dense and don’t understand the importance of the small details but I have met some architects who work for the council who really sparkle.

The enforcement section of DLRCoCo really stinks. I saw a fantastic old house on a hill some years ago had all its old windows (20) then recently I saw it again and all the windows had been torn out and replaced with god awful uPVC so I reported it and I was told I had to prove it. Madness
