What a great company. Everyone we dealt with was lovely from sales to office staff to fitters. Our patio doors and window are beautiful and so well made. Fitting was painless and we are so thankful and over the moon with our new doors. Wonderful. Thankyou.

I cannot recommend L&L Installations highly enough. Excellent service all round beginning with a clear and prompt quotation, the fitting was exemplary, no mess and a professional and friendly team. My queries were answered quickly and confirmed that I had made the right decision to use them. The door is perfect, in terms of quality and finish and they also provide free annual servicing which is a real bonus! Thanks so much!

I want to give my appreciation to the L&L team for completing our job of replacement windows and door. I have to say the whole process was an enjoyable experience for us. From the initial enquiry L&L, the first consulation, followed by timely survey and of course meeting the installation chaps, what a fantastic team L&L are. With their advice and guidance I had imagined how our new windows would look but the finished product has even surpassed those high expectations. My thanks go to the whole team and the Directors of L&L.
