View Full Version : Cost of double glazing a house

What sort of figure would you think it would cost to entirely double glaze a 4 bed detached house (no conservatory)? We will need to do this in the next couple of years, so need to get prepared for the costs.

No idea if this would be £2000 or £10,000. Anyone done this recently and know the ball park figure for this sort of house?

Thanks.

As a rough guide providing you arent after overly non standard sizes and styles I would budget for approx £300-400 per window, £500-800 for upvc doors (single) and £1,000 for 'french doors'

Cheers for that! That gives me a quick guesstimate of £7k - though I'd probably round it up to £10k, as the front door has small windows to the sides, and some of the windows are quite large areas.

Just to give you another idea.

Work starts on our house tomorrow to get all the windows done, and a new back door.
9 windows in total, and we're paying around £4800 for it.

£4800 sounds a lot better than £10,000! Suppose we need to get some quotes in - only problem is the Window Companies are less keen to come out when they know you're not looking to replace for a year or two!

Try your local Yellow Pages for uPVC window SUPPLIERS.

I got all mine , on a monthly basis,(had one delivered each month, and paid for them on delivery), and paid no more than £255 for the largest, which was 6 foot by 4 foot, with two openers.
I also did the front door, with two 3 foot square side panels, and a door, for £750.

I can take out, and fit new now in no more than 4 hours, although the door did take two days:eek:, as I had to build two half height stone walls!

I think a spot of DIY is coming up ..... :-)

So, without having actually done any other research into yet (as Scoobynet is the font of all knowledge ...) how are windows actually fixed in? Are they bolted or just cemented?

Cheers

Got my windows from a local is manufacturer with a bit of help from a friends hows a builder. Just told them I was a builder and they where happy to take my money ;)

The windows bolt into the walls and a bit of silicone sealant to keep the weather out.

You place the window frame in the opening, and wedge it where you want it, using window wedges from the same place you bought the window.

You buy "window fixers", about 40p each from Screwfix, and a long 10mm masonry drill.
Drill straight through the frame into the wall.
Hammer in the window fixer, one each side, straight through the frame, until it's head is flush with frame, and tighten the screw in the centre. There is a cone type thingy on the other end which should anchor the whole thing without distorting the frame.
Glaze with supplied units, and seal around with silicone.
Done.

Getting the old frames OUT probably takes longer, especially at first.
Remove all openers by unscrewing, or levering off at hinges if screws are unusable due to paint.

I put clear sticky-backed plastic onto the glass and broke the glass out of the frame if it was fixed.

Use a good saw to saw as far through the frame (in two or three places) as you can get, without damaging plaster. I used a new-ish tenon saw.

Lever up the frame near the cut, and continue until it goes right through.

Remove centre sections of framing, between two cuts.


Pull the side framing away from the brick work........work fairly carefully as you DON'T want to loosen any bricks.

Clean up the hole left, and fix as above.......one thing I ought to have said is to ensure that any fixing goes into a brick, not into a mortar joint.
And buy a good quality drill bit....Wickes do 'em cheap, I've used up two doing mine.

alcazar,
What local firm did you use to supply the windows?

I'm not far from scunny and need some for a house I'm renovating.
Previous supplier has fecked up too many times to use them again.

Cheers,

Bob

DIY

i had qoutes of between 8-12k for 14 large windows 3 doors and 2 french doors

Go to any trade place and i paid 5 k for the lot and they were identical !!
even if you had to pay some one 100 per window to fit it would be cheaper !!
most joiners would be happy on 60 per window

i did myself taken aprox 4 hours per window
you will need a skip to take the old ones away £100 max

salesman get 1000 of your money per deal also salesmanager etc

in you situation 3-4 k top wack !

Good idea to do one at a time start on the easy ones first

4X4BOB:
I used "Trade Windows Direct".
Found from Yellow Pages.
He's a window fitter, with a line into manufacturing frames, and does his own glass.
Good prices, good product, very helpful.

Is that the guy?

Nope. Not the number I used anyway.
I've just had a look in the real paper edition of YP, and it gives "your" number plus 01724 764434, which IS the number I used.

Top tip - if you pay someone else, check they actually DO bolt the frames to the walls.

I moved into a house which had had its back windows replaced, and the only thing that held them in was mastic! One night in a storm, the whole frame blew in! :eek::eek:

Curiously, the firm who did it was not in existence by then! images/smilies/mad.gif


Am watching this with interest as I've been quoted 5-7000 euros to repair or replace the leaky alu units in my new house. See how much I can get that down by.

Party-pooper here :D

IIRC, if you fit windows yourself, you have to get them inspected by a building regs type inspector, or they won't be legal

..and once he comes round and sees that, maybe, you altered the style significantly without getting planning permission, you're in for it...
..and when you come to sell the house, the buyer's solicitor might be a smart cookie and demand to see evidence that they have been inspected....

(I'm probably not using the right words here, but you get the drift...)

If a fitter/fitting company has the right certification (forgotten the name of that - as well - but I'm sure it starts with F!) then they can underwrite the job themselves

Worth a call to local building regs dept then:):

Last time I dealt with them while making my own conservatory, they were more than helpful.

I STILL say you'll get a cheaper, and probably better job doing it yourself.

You can usually get a copy of the building regs regarding windows from your local council (sometimes online). You can then install them yourself (to the regulations),then, when finished,call out the council officer who will give you a certificate if all is well.
Costs around £50 quid round here.
Also don't worry too much about poorly fixed frames blowing in as they are usually fixed up against the internal plaster or some other reveal, IMHO there's probably more chance of them blowing outwards..!!
One tip for removing the old frames is to buy yourself a cheap reciprocating saw, and from the outside, cut through any old nails holding the frames in (usually at each side), the blades on these saws are flexible enough to allow you to cut without damaging the brickwork on the outside face.
