Professional Groundworks for Extensions, Driveways & More
— About us
Solid groundwork is the foundation of any successful building project — literally. At Ray Sarll Renovations, our experienced team carries out a full range of groundworks services across North London, including excavation, foundations, drainage, concrete slabs, footings for extensions, and driveway sub-base preparation. We work on residential projects of all sizes, and because we handle the full renovation process in-house, we're uniquely placed to manage groundworks as part of a wider build — seamlessly coordinated with the rest of the project from start to finish.
— Our process
We visit your site to assess ground conditions, discuss the scope of the works, and provide a detailed quote that covers everything required before any digging begins.
Our team carries out all excavation work efficiently and safely, disposing of spoil responsibly and preparing the ground to the correct specification for the build above.
We lay concrete foundations, install drainage where required, and complete all groundwork to the standard needed for your structural engineer's sign-off or your next build phase.
— Benefits
Unlike standalone groundwork contractors, we work alongside our own building and renovation teams, making us the ideal single point of contact for extension and new-build projects.
From soft clay to compact gravel, our team has worked on a wide range of ground conditions across London and knows how to adapt the approach to suit your site.
Getting groundworks right from the start protects the entire project. Poorly prepared foundations or inadequate drainage can cause structural issues that are expensive and disruptive to fix further down the line. Our team takes the time to do it properly — working to engineer's drawings where required and maintaining clear communication with the wider project team throughout.
We carry out groundworks for a wide range of projects including rear and side extensions, loft conversions requiring new steels and padstones, garage conversions, driveway installations, and garden landscaping with retaining walls. Whatever the scale of your project, the quality of our groundwork preparation sets the foundation for everything that follows.
— FAQ
It depends on the nature of the project. Foundation work for a permitted development extension generally doesn't require separate planning permission. We'll always advise you clearly on what's needed before we start.
Speak to our team today and we'll arrange a site visit to assess the job and provide a clear, detailed quote.
— Other Services
We manage spoil removal, drainage, and material delivery carefully to minimise disruption to you and your neighbours throughout the project.
