Wooden, double glazed, replacement sash windows.

[Lindle]

We’re hoping to purchase a small Victorian house which has original sash windows and hope to replace the front windows, a small bay on the ground floor and a single window above it, with double glazed replacement sash windows. There are a further four sash windows which subject to affordability we will replace with wooden windows also. However, if the cost is prohibitive we would opt for UPC wood grain effect sashes.
Can anyone indicate what the cost might be? We are in West Sussex.

We've had a rough estimate for wooden sash replacements at 2k per window, and wood effect uPVC 1k per window. We have a five window box bay at the front so that would be 10k just for the living room alone if we choose the wood. We are in Scotland.

Thank you, I knew it would be expensive and as I assume the cost will be higher in West Sussex it looks likely that we will have to have a combination of wood and wood effect UPVC. Fortunately our bay only has 3 windows.

Do bear in mind that UPVC have a limited lifespan and then end up in landfill - cannot be recycled. Wooden windows can be repaired and maintained. You can also consider secondary glazing for warmth.

You get better ventilation with the original windows - beware of putting in UPVC and suddenly getting issues with mould. Also make sure you aren't in a conservation area which restricts using anything other than the original. We are in one and the neighbours are very hot on policing any work done on the road and wouldn't hesitate to inform the council!

When I looked for ours about 2yrs ago (4 large bedroom windows) it was around £25k to replace with wooden sash double glazed windows. I ended up getting a lovely carpenter to re-bead and repaint instead which was considerably less. No solution to noise issues though.

Feel like I need to clarify that's 2 bays and a small side window.

We’re having this done at the moment- London prices admittedly but I’d say it’s minimum £1.5k a window.

Note that this is keeping the original boxes and just replacing the sliding sashes. If the boxes were rotten and needed replacing too it would cost more - maybe £2k a window.

I currently have UPVC double glazing and have never had a problem with mould, although I do keep the trickle vents and my bedroom window open all the time. I really do want wood but as my budget is £30,000 maximum I may have to compromise. I’m not in a conservation area.

Will the company you are using take on jobs in West Sussex; East Grinstead to be precise?

I'm in Brighton. A large intricate bedroom window was 3K for secondary glazing and full refurbishment. It's expensive.

@minipie which company was this? Are you happy with the new windows? Any pictures please? 🤩

Hello! It was Deltahome (Greg is the main guy). Very happy with the windows, they were very helpful about some bespoke changes too and stained glass repair, only issue is we did need to chase about installation dates but not a big deal.

@minipie thank you for the info. How long did it take from deposit to installation? I presume you opted for Accoya? So many options and with the extortionate prices it’s an expensive thing to get wrong.

Hello, i can say that i depends. In my local residence double-glazed sash windows cost aroung 2k per window, BUT you need to try to talk with your local architectural glazing company (smaller the better) they can make it cheaper and better, UPVC wood grain it's cheaper buy itself but anyway find good opportunity and catch it! Good luck!

Hi, sorry for late reply, just saw this. I think there was a bit of time spent discussing design/spec and then once the spec was finalised it was another 2.5/3 months till installation. But I could be misremembering

I used a company called Firth in Sheffield. I'm in a conservation area in London and they custom made replacement wooden sash windows. It was several years ago so the pricing would be irrelevant but they did a good job and it certainly wasn't priced over the odds compared with other suppliers.

youre right, everyone here is talking about their preferred companies, and, as you can see even prices from place to place differ so i can only wish op good luck with work, and, of course i hope OP will find best architectural glazing company in their living area

so saw here everyone is sharing their experience with replacing windows so i wanna share mine maybe for some1 this will be useful, so, i was replacing sash windows w my wife 3 years ago when we moved into new house here in Hertfordshire we found one good architectural glazing company which helped us w window replacement, dunno about other companies but these guys are nice pm me or reply i can share more bout my experience

do you possibly have a photo of your windows? Only I need to look at doing this in my Hove flat and it'd be good to see the size of yours for comparison on the quote. thank you!

We looked into this. We've got 18 huge sash windows and it came out at over £50k. We don't have the money so put it on the back burner for a while.

In the meantime we've invested in magnetic secondary glazing for some of the downstairs windows which really helps with heat retention and noise reduction

Following as the house we've put an offer in on is in a conservation area and has mostly single glazing.

We paid £2.5k per sash window, including new frames (all Accoya) in London a few years ago. These were decorative Edwardian sash window replacements though with arches at the top.

It’s a bloody fortune! Somewhere between £2 and £3k per window, a lot more if it’s a bay etc. Just about to complete on a house with original single glazed sliding sashes and they need to go. We have budgeted to do it because it’s listed so no choice.
Current house has uPVC sliding sash. They actually look really good and we have no problems with damp or mould and they suit the house (1930s build). We didn’t put them in but they are a fraction of the price of wooden windows and maintenance free.

Our bay cost £7k although it was a long time ago and London.i do love them (we are in a conservation area so it had to be wood).

Almost a year old thread, I wonder what you did. Just to add confusion, some original wooden sash windows can take ultra thin glazing.
