What our clients say
Thank you brilliant service from you guys. I can't tell you how much that had helped me out this week !
Steve Cooke
We strive to pioneer and produce the most technical and aesthetically accurate sash window as possible. This means thoroughly testing new designs and manufacturing techniques before bringing innovations to market. Being able to work with a Professional but flexible organisation like Build Check, to test these innovations to the appropriate standards and to develop new techniques where a standard doesn't exist is a cost effective and essential service in the R&D project.
