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.
