Windows Question

How much does it cost to doubleglaze a 3 bedroom house with 12 standard upvc windows?

I'm looking to double glaze an entire modern build 3 bedroom house. 12 windows total and 2 doors. Only standard upvc (frosted for the bathroom window).
I've had so many varied quotes, I'm not sure who to believe. Ranging from 3000- 10000. Could you clarify for me an estimate of what it should cost. (I know for a more specific cost, I'd need a buider to view the property).

Depending on sizes, openers etc you should budget for about £350 per window fitted. Doors range in price depending whether you use UPVC or composite doors.
A realistic budget would be £500 for UPVC and £900 for composite depending on who does it.
This makes the total job about £5600.
Difficult to give exact figures and ranges of window quality is huge.
Hope this helps though.

Average cost for a window is £300 fitted and a uPVC door is £550. Total cost should be around £4600 - £5000. Make sure you get an insurance backed guarantee if the firm is a small one. We fit Rehau for these prices. Aim for a rehau supplier if you can . Veka, Synseal or Swish are mid range but also quite good.

It will all depend on a few factors.

1. Size of windows.
2. Style of windows ( how many openers / plain glass / leaded glass / georgian bar glass / casement window/ bay / bow window / sash window.
3. colour of windows white ( standard )/ woodgrain colours ( a lot more expensive).
4. Door style i.e upvc ( has lots of differnt styles) / composite ( the better option in my opinion as they are very secure and come in some very nice colour and glass options).
5.Quality of the product / rehau /veka are my main window & door suppliers and i very rarely have any issues with them .
Like you have posted on your questions its probably best to get someone in to take some measurements and to discuss the style options this way they should be able to give you an exact quote.

£10,000 is a bit expensive..without saying names i can guess who they were from...also £3000's a bit cheap and would definitely question what product they are using and it's this is every important. Try doing a bit of research into the different product's and ask your decided company to quote using that product..Rehau, Kommerling and Deceuninck are some of the leading names in upvc windows and doors...any good company wont quote you over the phone but will request a time to carry out a full survey as they need more info then just sizes.

The price all depends on the styles and the spec of the windows, hinges, locks and glass. If safety glazing is required then this could dump the price up. Also if you are looking at A rated windows then this would also make the cost much higher than C rated.

Its difficult to give a price without knowing styles and sizes

Hope this helps?

with out seeing your property it would be very hard even to give you a rough guide price for replacing the windows due to different specifications ot types of windows around , pick out 3 window companies close to you and get accurate quotes ,and check with the guarrentees offered theirs a lot of companies out there bidding for the work so you might save a few £££££££££
