Clients Say!

L-Shaped Dormer, Sutton, SM1




Our loft conversion looks brilliant, we love it and we have been so impressed by Custom Lofts. Everyone who has come to work on the loft has taken real pride in their work, has worked hard and efficiently and helped to create the best room in the house! Dean has managed the job brilliantly, organising everyone who needed to come in, and he kept me informed every step of the way so I knew exactly what was happening when, and my son Max insisted on having his photo taken with Dean and Billy before they left which is testament to the great working relationship we had during the job. And it goes without saying maggie has been brilliant.
