Review by Michael Brophy
on 27th August 2025
"I cannot praise this Company enough for their professionalism, their expertise, the quality of the work, arrived on time, worked late each day to get the job done, cleaned up every spec of dust, friendly, professional and a great team. We have had replacement windows, and a new porch, and will definitely go back to these guys. I wished they did other work as these are the go to people that you need to work on your home. A particular shout out to Simon Howard who organised the work, measured up perfectly and kept us informed, and to Gary Miles who attended site and worked continuously without a break delivering excellent quality. Never had a workman in our home starting at 9am and finishing at 7pm (unheard of), but these guys did, on both jobs. The result of their workmanship is an amazing professional quality job and we are delighted. Will recommend them without any hesitation."
