“Having worked with Sage Building Envelope Contractors on a number of large Design and Build projects and tenders where their package has included all of the roofing and cladding elements I have found them to be very knowledgeable, helpful and capable in all of the construction phases from tender, value engineering, detailed design, construction on site, variations and Final Account.”

Andy Knott, Senior Project Surveyor, Parkgate

“…We were pleased with Sage who were our envelope contractor on the School of Engineering Building at University of the West of England (UWE). There are always issues to overcome, not least Covid-19 lockdowns at critical periods in this case, and Sage’s reaction to these in taking time with us to consider how best to proceed, and a willingness to be collaborative with our build team, is always helpful. Quality of end product was never compromised either, and Sage as one of our Category 1 Contractors are testament to the benefits of a partner supply chain.”

“Sage were thorough and efficient throughout the pre-construction stage, Design Manager Kate Tuckley was highly technically competent but also proactive in identifying issues and resolving them with the wider team. Sage were able to coordinate their design holistically with consideration for other trades whilst still providing robust details.”


Joe Henson, Design Manager, BAM Construction, President Kennedy School

“Sage were proactive during the tender process and offered their specialist knowledge and proposed product to help develop the architect’s design… Once the subcontract was agreed, their detailed design was key to the overall co-ordination at roof level. I found Sage easy to communicate with throughout the process and the quality of the product was high.”
