  • I have worked with BBL over the years and specifically Chilli who I have known for over 6 years. He has been involved in various projects I have had over the years, many relating to small jobs as well as apartment blocks where we completely replaced all the windows. He and his team are a pleasure to work with and Chilli who is very passionate about anything to do with glass brings far more to the table than just that of a Managing Director within a double-glazing company. BBL is well priced and they provide an excellent service and aftercare. In the very near future I will instruct BBL to quote prices on a new development that we are currently completing, without hesitation.
