Today, we said goodbye and good luck to our co-founder, Karl Williamson, as he leaves Window Ware to pursue new career challenges with leading UK profile manufacturer KÖMMERLING.

Karl has been a driving force behind Xpert Tools since its inception in 2010 and came with us 6 years ago when we moved to our new home at Window Ware. With his help, and with the support of a superb team at Window Ware, Xpert has become a household name among glazing professionals and is now sold in over 300 stockists across the country. And its popularity is growing all the time; in the last 5 years alone, Xpert sales have grown by almost 48%!

With Xpert Tools undoubtedly thriving and in capable hands, it’s not surprising that Karl feels now is the right time to move on to his next big adventure and we wish him every success in his future endeavours.

Ahead of his exit, Karl has worked closely with his Window Ware colleagues to ensure a thorough handover and smooth transition for our Xpert customers.

As always, our stockists can expect the very same prompt and friendly response, and broad expertise they’ve been used to all along.

Our sales team can be contacted in all the usual ways: by phone: 01234 242740 or by email:
