We provide a range of tailored services.
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.
In 2002, we were delighted to design, supply and install ornate granite features to the floors and walls of this award-winning London restaurant. Since then, we have carried out regular maintenance works including deep clean of flooring and repairs to bar stone bar tops.
In 2015, Stoneguard delivered an extensive renewal and restoration project to this extraordinary Grade I glasshouse. We carried out cleaning and repairs to the Victorian façades and paving, and we reinstalled the magnificent stucco render.
In 2017 we supported the refurbishment of this sizeable commercial building to provide 200 luxury residential apartments and prime retail units. Stoneguard supplied and installed aluminium cladding, Vitrabond, Corium brick slips cladding systems with Sto Ltd, Ventec Render and Sto Therm Classic render systems to the external facade.
When this 1960s office building was converted to residential use, Stoneguard took the lead on cladding. We removed 18 storeys of aluminium composite cladding, amended the existing facade and installed new A1 fire rated metal cladding.
Since 2019 we have been responsible for internal deep cleaning of cigar rooms, and marble scrubbing of main reception areas and lavatories. We hot wash external façades and restore front elevations and front courtyards to keep this prestigious hotel looking its finest.
Following substantial fire damage in 2007, Stoneguard was asked to complete a full facade restoration and terracotta installation of this iconic city centre building. We delivered the design, manufacture and installation of new terracotta and brickwork, and the cleaning and restoration of the existing Belmont facade, which dates back to 1899.
Our core values underpin the way we work with our trusted clients and supply chain partners. These are at the heart of every Stoneguard project and every relationship. These 5 values are embedded throughout our business. They ensure our shared success, account for our remarkable track record, and support Stoneguard’s mission to be the go to specialist facade contractor in the UK.
By working closely with our valued clients and suppliers, we deliver the highest quality solutions and achieve the best outcomes for all parties.
We dedicate ourselves to achieving excellence and in going the extra step for our clients. From tender to completion and handover, you can be assured of our unwavering focus on quality and delivery.
We challenge ourselves to create unique solutions to complex challenges. At times this requires new approaches, new systems or new products - we think creatively to deliver the best possible results for our clients.
We take pride in the strong and trusted relationships we build with clients old and new. Our collaborative approach offers a highly personalised service as we recognise that each and every client has a unique set of needs. Much of our work is through repeat business and recommendation - no better testament to our enduring client relationships and to your confidence in our commitment to quality and delivery.
We partner with the most trusted suppliers on the market, who share our insistence on outstanding products and systems. We require rigorous testing and accreditation, to ensure our work is of impeccable quality and that it stands the test of time.
Regular training sessions with our partners help to ensure best practice from our teams - so operatives and management install to latest standards and specifications.
At Stoneguard, we believe in giving back to the communities in which we work. As a family-run business, we take a long-term view - supporting local initiatives, grassroots sport, training opportunities and skills development that create a lasting positive impact.
Stoneguard is proud to sponsor Gamlingay United FC Under-8s for the 2025–2026 season, helping to support the positive impact grassroots football has on young people. More than just a sport, grassroots football builds confidence, teamwork, discipline and community connection.
Congratulations to Ajinth Srikanthan, a local Construction T-Level student, who recently completed a six-month placement with us. Ajinth worked with the team two days a week, gaining valuable hands-on experience on site at our Northolt High School project, as well as office experience supporting our admin teams. We’re proud to help support the next generation of construction professionals.
As part of our SFS and brick slip works at Priory Common School in Milton Keynes, we collaborated with project partners to add social value by providing the SFS frame and timber cladding for ‘The Priory Cottage’ - a 3m x 3m insulated outdoor space for reading and play, promoting literacy and wellbeing in the fresh air. Well done to the ASHE team for leading this initiative!
We are also one of the primary sponsors of the ASHE Construction cycling team, who recently completed an ambitious 500-mile challenge across France, Germany, Switzerland, and Luxembourg in three days to raise funds and awareness for charity. We are proud to support this initiative, which reflects our shared values of teamwork, endurance, and giving back to the community.
