    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...

Become a fitter


Become an Approved Extraglaze Fitter


Being an Approved Extraglaze Fitter is a genuine addition to your portfolio. Please note especially that winter is our busiest time, just when many trades suffer a quiet period.


We get "Fitted by Us" enquiries from all over the country,
with projects ranging from one window to van meddozens. We want to be able to pass on these enquiries, free of charge, to nearby fitters that have been approved by ourselves. If you are a tradesman or consider yourself similarly skilled then we would be happy to hear from you and guide you through the approval process.


There are no fees or subscriptions. However, Extraglaze must give our customers confidence that all the fitters we recommend have been approved. For this reason you would be required to complete a training course, here in Shropshire.


Approved Extraglaze Fitters offer the following services free of charge locally, just like we do ourselves for enquiries close to our main office:

  • Survey a property
  • Provide a fixed price quotation

Perhaps best of all, our customers rave about Extraglaze, consequently many installations that you complete will generate others, from a friend or neighbour.


The benefits of becoming an Approved Extraglaze Fitter

After successfully completing a training course here in Shropshire we will give you:

  • qualified customer leads
  • free phone support, including Skype, email, etc,
  • help on site when needed (this would be chargeable)

All purchasers of our products have a dedicated 'My Account' online, so you can order 24/7, with full traceability.


Contact us to enquire about becoming an Extraglaze fitter.
