Why our extension excavation works well
Built around your plans
We dig to the required lines and sizes to suit the extension layout.
Good access thinking
We plan the machine route carefully where homes have tight working space.
More than one task sorted
Linked trenches and drainage digs can be planned with the main excavation.
Extension digs that keep the build moving
Extension work only stays on schedule when the dig underneath it is right. At M & M Man & Machine, we carry out operator supplied mini digger excavation for house extensions, including footing trenches and dig outs that need clean lines and accurate depths. From Southam, we help homeowners and developers prepare for the next stage without turning a simple extension into a drawn out groundwork problem. Our 40 years in the building trade help us understand how extension excavations connect with drainage, service runs and site access, especially where space around an existing property is tight.


A practical approach from first call to first dig
Before we book the job, we ask about the size of the extension, drawings or setting out details, access for the mini digger and whether the work is a one day dig or part of a longer project. We can also plan related excavation on the same visit, such as drainage runs, service trenches or clearance that opens the area up. At M & M Man & Machine, we keep pricing straightforward and timing dependable, so your builder is working with a prepared site rather than waiting for groundwork to catch up.
Frequently asked questions
What details help you price extension excavation?
Plans, footing sizes, the rough dig area, access for the mini digger and any known service routes all help. If you already know whether spoil should stay on site or be moved, that makes the planning clearer and helps us scope the work more accurately.
Can you dig extension footings and drainage on one job?
Yes, if the project needs it and the scope is agreed upfront. We can coordinate extension footing excavation with drainage digging or service runs, which helps reduce separate visits and keeps the groundwork stage more organised for you and your builder.
Is this suitable for one day jobs and longer builds?
It is. Some extension digs are straightforward one day jobs, while others form part of a wider programme with several excavation stages. We can plan the work around the build sequence so the site is ready when the next trade needs to step in.
