Curlew, thanks so much for taking the time to post your progress, I'm following keenly.
Working up my own spreadsheets at the moment.
do you mind me asking what type of windows you've sprung for?
Well because it is in the National Park we have to have traditional sash appearance windows (though not all houses in the village have them these days), but we could not find real sash windows with a good enough U value, which is
really fundamental to what we are doing in this build, (well you could get close, but you'd be talking £25k+ just for all the windows!) or that I was convinced would genuinely stay draught proof in the long term. So I've been looking for traditional sash
appearance windows for probably nigh on the full 3 years now. Going to the self build shows
* we were able to get quotes from several manufacturers which vary wildly. Current leader is the Green Building Store however. I'd love triple glazing, but price simply forbids it. Why 1 extra pane of glass should add so much cost is a mystery, and I strongly suspect it's an artificial price hike.
Lesson 1 I learned is that the volume window suppliers (you'll know the names, you see them names on T.V, newspaper and often radio advertising) are a waste of time unless you are simply replacing bog standard windows on a standard volume build housing estate house. Anything other than that like a new build, and their brains explode!
I ended up with a lot of wasted time when I explained I wanted quotes for supply only for new windows to go in a
new house which is not built yet - fine, yes we can do that they (all) said, and then 2 got a rep to call (I hate having reps in the house and will never sign anything there and then, which I tell them from the very start), even though I explained there's no point as I could give them the specification sheet showing all the sizes down to the mm and detailing exactly (i.e white frames with white furniture, and full diagrams) what is required and they could come back with a price for supply only. Anyway,
invariably, a while later I'd get a call saying the rep wanted to go and measure the windows, and I'd explain
again that the house isn't built yet so they'd be stood on a stepladder in a field measuring an imaginary house! They'd say that they'd come when the house was built to measure and I'd explain that I could not have the house stood with no windows in it for weeks on end, hence ordering the windows in advance for supply only. "but what if the sizes are wrong? They'd say - that would be
my fault I'd say, since I am giving you the measurements, so no come back on you. Anyway, this was all far too confusing and they'd say they couldn't do it - then a couple of weeks later I'd get another call saying a rep wanted to come and see me, I'd explain what had happened and they'd say "no, of course we can supply the windows for you" - then a week or so later another call saying they could not! (one well known firm did this 4 times until I told them to stop wasting my time).
Lesson 2 was the amazing variation in price from the smaller bespoke manufacturers - it's well worth trying a lot because the price variation for the very same specification product is amazing. One supplier with a good web site showing lovely work and a quote which looked really promising was dropped when I did a search and found several complaints of deposits paid and many months after the agreed supply date no windows turning up, or being massively the wrong size. So you do have to be really careful. On the self build forums there are a
lot of horror stories of wrong sized or failing to appear windows.
