Stoneguard was founded in 1963 to specialise in high quality restoration and cleaning of historic building façades. Our services have evolved over 60 years to include an extensive range of cladding and render solutions, and our exclusive lightweight steel framing systems. But one thing remains the same - innovation and excellence are at the heart of everything we do. From historic to contemporary, stone restoration to steelwork, we deliver consistently exceptional results to our clients.

History & Expertise

Stoneguard’s 60 year history is a story of dedication and passion for quality. As our business has expanded, so too has our range of expertise and our capacity to deliver increasingly large and complex projects.

Following substantial fire damage in 2007, Stoneguard was asked to complete a full facade restoration and terracotta installation of this iconic city centre building.

Health & Safety

Our dedicated Health and Safety consultant manages best practice across Stoneguard. From correct training to certifications, our personnel are fully compliant with the highest industry standards. And we ensure we uphold all site and company requirements across our projects.

We require all management to be SMSTS and SSSTS qualified, and check that every operative possesses an up to date CSCS card. We also ensure that all personnel adhere to relevant risk assessments and method statements (RAMS) of works. In line with recent fire safety legislation, we have further evolved to provide remediation solutions for unsafe cladding that does not meet British Standard BS 8414. We hold FIRAS 3rd party accreditation in the application of passive fire resisting products using cavity barriers, further cementing quality standards and commitment to this nature of works. Stoneguard holds a UK government approved Waste Carriers licence.
