Darren and his team have completed a number of jobs for me. Their pricing is competitive, they provide great service and a wonderful finish.

We had all our windows replaced by Swallow Glazing. We opted for a slim line black aluminium style and they look fantastic. Would highly recommend, especially if you want something decent doing because this company showed really care when doing all the making good to ensure the slim line profile of the windows was retained and look amazing.
