There were long term leaking problems from our bay window. The three fitters from Window Workshop very efficiently removed the old bay, showed me what the problem had been and very skillfully fitted the new bay, coping really well with the fact that the bay had shifted over time. They were incredibly nice and carefully kept the room clean. It was quite a big job, but they worked hard in cold conditions and got it all weathertight by the end of day 1 and spent another half day finishing it off inside and making good. Overall result is very good. Would definitely use them again.
