MegaSack DRAW - 6pm Christmas Eve - LIVE on our YouTube Channel
Having just had the pleasure of preparing our sash windows for repainting and finding most of the frame rotten (after this, I think they'll be more plastic wood than actual wood!) it seems that we'll need new windows in the next few years.
I've got absolutely no idea how much replacement wood sash windows cost.
Has anyone had it done, and if so are you willing to give an indication as to cost?
I'm assuming it's probably around £1,000 per window but don't know if that's wildly optimistic or pessimistic (I suspect the former...).
Oh, and before anyone says, no, we're not replacing with PVC.
I had 8 sash windows and a pair of patio doors done in hardwood about 7 years ago and it was £18k I think. They were big windows mind and hardwood. I suspect it was a bit more than it should be but there were limited people at the time in the area who did them
expensive! Couple of years ago I got one. I have to have wooden sash and case being a listed building. I did get historic scotland allowed ultra thin seal double glazing in them Its a big window around 1m x2m with 4 panes ie mullioned. Well over a thousand supplied and fitted maybe nearer two- can't remember exactly. I did have it made specifically to size by rick from on here ( can't remember his forum name off the top of my head. Its also got draft excluder brushes fitted and brass fittings
Had a pine one done a couple of years ago for about £800.
Other quotes were way over £2.5k for hardwood. The old pine window was installed in the 50's so we decided hardwood was massive overkill.
No idea of the cost (and it was in RoI), we did a whole house but very pleased with Munster Joinery's Windows and they operate in the UK now. We went for a double glazed version of their heritage sliding sash and they've been very good
thinking about it it was £2000 - but 400 of that was for the heritage spec double glazing which I really would recommend and also includes "top floor tax" I guess 😉
Thanks all.
Ours are 1.0 x 1.8m, 2 over 2 glazing with hidden vents, brass fittings and supplied painted. Cost about a £1000 each, but we fitted them ourselves. Actually putting the window in the hole and making secure, wind and watertight was straightforward - finishing the paneling and surrounds was more complex but could be taken more slowly once the window was in. The neighbour got same sized windows but 1 over 1, for £800 unpainted. They don't look so nice as ours, and he then paid £100 to get them painted.
I regularly supply and fit sliding sash box windows, London based, I would generally quote them at £2500 per window fitted and decorated inside and out, that's including the more expensive slimlight double glazed units.
How about
Oh, and before anyone says, no, we’re not replacing with PVC.
I don't get the PVC sash hatred myself, ours are coming up to 20 years old (next April) and have been absolutely faultless. They look no different to wood painted white, only need zero maintenance. Sound proofing is better as they use thicker double glazed panes and each sash is much heavier than a standard wooden double glazed sash. Would pick the same again. £800/sash in 1999 IIRC.
uPVC has a shorter life than wood,( 25 - 40 years compared to 100+) look awful and have huge ugly glazing bars compared to the beautiful moulded mullions you get with quality wood. they go yellow, the sealant perishes and goes grey. Anyone who thinks they look like wood has not seen a quality wood frame.
Yes wood needs painting every 5 years or so. Its a price worth paying for the quality and beauty.
118 years and still going strong my wooden sash windows. Paint every 5 years and had new waxed rope about 15 years ago. Love them.
glass with bubbles in is a bonus
rear of house is rapid yellowing plastic fantastic.
'kin 'ell at those prices I think I'd learn to make my own.
anyone wanting sash windows in the south east could call on the services of “The Sash Guy” aka Guy Chadwick, songwriter and performer in The House Of Love.
Any suggestions for companies doing Sash and Case near Glasgow? I’ve been quoted £1300 for sash replacement in hardwood and double glazed, the existing case will be refurbed in situ.
£1300 is not too far off the mark for that, are they single pane, twin or Georgian six pane?
A good refurbishment can do wonders, replacing rotten timber etc. We had ours done a couple of years ago and they're wonderful.
Now selling the house and the buyer is getting a quote for new pvc. I could cry.
In London and we're having ours done bit by bit. Just looking back at previous quotes. A 1525mm x 1200mm was £1200 including VAT and fitting. Very pleased - bomber solid.
These guys were quite a bit cheaper and more responsive than a number of other London suppliers - who pushed the spring sash window/ non opening sashes. One explanation is that the company is run by a Polish guy and made in a workshop in Warsaw.
Ours on an Edwardian Semi averaged about £1k per window. Some had both new sashes, some had sashes and case and some just refurb and repair. Joineryworkshop in Manchester.
Just to add another option. A friend of mine has a business repairing wooden windows with a resin repair system. As a traditionally trained time served chippy i was very sceptical of the products and couldn’t believe that anything could be better than a hardwood splice repair but when my own windows required repairs he offered to show me how his stuff worked. I will admit that this is much better and cheaper alternative to replacement and once finished will last longer than a new window. We did the repairs and the windows were painted in Sadolin super-dec 4 years ago and still look as good! The products he uses is called Repair care and they have a list of registered contractors but I’m sure that you can buy it independently from some decorators merchants.
Edwardian casement windows replaced by a skilled and much missed mate at about £1000 each. Engineered sustainable hardwood. Big windows some of them so defo mates rates was applied. Look lovely and another vote for sadolin superdec for soaking in and lasting well without the peeling you get with a conventional paint system.
Not sure if it's used in sash construction but I would avoid Idigbo if offered.
Set money aside for the first painting of the windows, I have lost count of the times where i have seen very expensive new windows ruined by poor decorating, Even hardwood windows can rot depressingly quickly.
Use a preservative primer to impregnate the frames and the bottom rails of the windows, or a penetrating oil like Valtti base. As said above the newish water based systems can work well over well primed timber, sadolin superdec or Zinsser allcoat exterior. And if the fitter wants to stick the glazing beads on with silicon, shoot him. The new adhesive/sealants are so much better,

Thanks - looks interesting, I used a two-pack epoxy filler to repair the worst areas this time, but this stuff looks tailor made for frame repairs.
