S M K Building & Maintenance Ltd

About us

Founded in 1991 by a partnership of skilled tradesmen and family members, SMK Building and Maintenance has grown from its roots in Barry into one of the Vale of Glamorgan’s most trusted names in property improvement and maintenance. Built on integrity, reliability, and high-quality service delivery, the company rapidly established a strong local reputation and expanded steadily over the years. A key milestone came in 2002 when SMK became a private limited company, enabling further growth and diversification. Since then, SMK has secured major contracts with local authorities and public sector organizations, underpinned by a clear commitment to excellence and innovation in service delivery. Today, with a workforce of over 60 certified and experienced tradespeople, SMK has become a leading provider of retrofit, refurbishment, and redevelopment services across South Wales. Now PAS 2030 certified, SMK is well-positioned to deliver compliant, high-quality energy efficiency retrofit works, with a particular focus on External Wall Insulation (EWI)—a key solution in reducing fuel poverty and improving the thermal performance of homes. As we celebrate over three decades in business, our unwavering focus remains on delivering tailored, effective solutions that meet the evolving needs of our clients and communities. Based in Barry and active across the region, SMK remains a dependable, forward-thinking partner for sustainable retrofit and property improvement solutions.
