    Seems a good product and blends in very well with our decor.
    I had internet quote which was straightforward with good tips and advise on the measuring. Felt confident when I sent it that it would be ok.
    I sent for quote as diy and fitted by extra glaze and my only thought was that their quote for fitting sounded quite high.

    Thank you Lee for the positive feedback. It is true that the labour cost of our Fitted by Us service can be quite high. This is dependent largely on the distance from our nearest fitter and whether the work can be done in one or a series of days that might include overnight stays, etc. Just like we...

    What a difference!! No more cold blasts when you pass the windows.
    Very nice chap from Extraglaze fitted the product to my very draughty sash windows. The price did come up a little more than the on line pricing tool but nothing is perfect. Very clean and tidy workmanship and completed within the agreen time scale.
    Product : Very discrete panels...

    Cannot recommend highly enough - superb service and standard
    First class - I made a mistake on my measuring and Nic and his team could not have been more accommodating. Glazing is now in place and looks superb. The white border on both glazing and inner magnet (ensuring it still looks discreet in summer when the glazing is removed) is very good...

DIY Delivery & Installation

 

 

flat surface troubleshoot 1Extraglaze is applied on the inside of any window, never outside. Some windows will only require one panel of Extraglaze. More than 3 panels is unusual, except for bay windows.


When looking at your windows all we need to know is that:

1 there is a flat surface all the way around each window

2 the flat surface is in good condition (good paintwork)

 

 

Flat surfaces absent?

In some situations one or more flat surfaces are missing. An example is shown in the animation to the right. Our fitters are resourceful, and can usually add a very effective instant, white flat surface.

 

Sash Windows – parting beads

On sash windows the flat surface is often interrupted by the parting beads (as shown above).

Our fitters will usually be able to bridge this without modification of the bead.

 

Window painting

If you are painting your windows in advance of Extraglaze it is very important to do this to a professional standard. This would include removal of loose paint, a good sanding down, cleaning with methylated spirits (use white spirit for oil based paints), and primer applied before undercoat or top coats.
