Customer Testimonials

They stepped in at last minute as an urgent job to get us through remedial roofing work from a previous builder who had not obtained necessary building regs and had then needed remedial works to pass certification. We cannot recommend them highly enough.

We were replacing two older sheds and wanted one that covered the same footprint and blended into a more traditional garden. Wouldn’t hesitate to use them again and recommend them to others.

They designed, built and installed a porch and a new set of garage doors for me. Nothing is too much trouble, they kept in touch with me throughout the process, answered any questions I had promptly and worked with me to deliver exactly what we wanted. I would definitely recommend them.
