    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...

    Product : We fitted one window first to see how they were. Reasonable simple to install for 70 year olds. Brilliant product which looked amazing and prevented the condensation (mostly) straight away. there is still some...
    This condensation is a good sign, that the wooden frames are drying out - moisture is perspiring from it! This is a great result for your precious window frames. You can take the panels off to wipe down the windows (while the moisture is condensed on the outside glass), but don't do this early in the...

    Product : We have fitted 8 windows so far. They look amazing, almost invisible. Condensation immediately disappeared on 5 windows with just a small amount on the other 3. I think this is due to damp windows which...

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.
