Very happy with XL Windows. I went to a number of different window companies in the area for quotes. Some were outrageous, others never returned my call. Chris from XL Windows came round, measured up and gave an incredibly reasonable quote for replacing my bay windows. The service and reassurance throughout was great and I didn't even have to pay anything until the job was done and I was happy with the result. Highly recommend.
