Local Builders You Can Trust
We run S.T Contracts Ltd as a family-led building contractor dedicated to delivering dependable, high-quality construction services in Watford and nearby areas. Our background spans more than twenty years within the industry, allowing us to approach each project with practical knowledge and careful planning. By retaining all trades within our company, we provide clients with a single point of responsibility and a clear, organised build process. Our affiliations with recognised trade associations, alongside full insurance and vetted staff, support our commitment to professional standards.
Our core services include house extensions, loft and garage conversions, and the construction of insulated garden rooms suitable for year-round use. Each project is designed to integrate seamlessly with the existing property while meeting the client’s functional requirements. We offer free quotations and 3D designs to clarify expectations before work begins, followed by clearly documented agreements. Upon completion, we carry out a detailed snagging process and provide a six-month guarantee on workmanship. Our business continues to be built on local knowledge, consistent delivery and strong client recommendations.
