Do you survey before making anything?
Yes. We measure on site and you sign the workshop drawings before anything is made, so we take responsibility for the sizes.
Can you work to my architect's drawings?
Yes. Most of our work comes from architects' drawings; we check the openings, details and Building Regulations points and draw the windows and doors to suit.
Do you do supply only?
Yes, for contractors who install themselves, with technical support while we quote and delivery to site if needed.
