    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...

    Great communication. Really good product. 2 weeks delivery.
    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.

    Very helpful on the phone. 2 week turnaround. Really good product.
    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...

Remote surveying and using local tradespeople

 

Free remote surveys

We can survey your windows free of charge remotely. If you have a smartphone or tablet and broadband we can offer this service and talk with you at the same time. You will need:

  • a smartphone or iPad/tablet with a camera
  • a laptop with a camera

We will guide you as we look together at each window, looking for any issues that need to be addressed, and also as you take measurements, which don't have to be precise. In most cases we can then calculate and give you a fixed price for the work. For some situations it may highlight the fact that we need to visit to carry out a detailed survey. Depending on your distance from us, there may be a charge for a site survey.

Use a local tradesperson to cut your costs

We are always looking for trades people to expand our network of fitters. We will train them to our high standards and credit them as Approved Extraglaze Installers. Once approved we offer access to a range of additional solutions we have developed over the years. Our fitters charge their own fees for installation. Consequently you will get a keen, locally delivered service at an economical price.

Alternatively please send us photos of your windows by email, to This email address is being protected from spambots. You need JavaScript enabled to view it.
We can then review your pictures and offer our best solution and guidance with how to measure.
