Groundworks & Excavation Experts

Groundworks and excavation are the foundation of every successful build — site clearing, levelling, digging foundations, drainage routing, and structural prep. Tower Age Constructions delivers groundworks across Harrow, Stanmore, Pinner, Edgware, Bushey, Northwood, and the wider HA postcodes. From small residential foundations to full site preparation for extensions and new builds, every job is engineered properly from the ground up.



Groundworks become necessary the moment a project goes below the surface. Maybe you're adding an extension that needs new foundations. Maybe a basement conversion requires excavation. Maybe drainage is failing or a slope needs retaining work. Whether you're building in Stanmore, extending in Edgware, or rebuilding in Bushey, Tower Age Constructions delivers groundwork that meets full building regulations and lasts.

Every groundworks project starts with a free site survey, where Tower Age Constructions measures the site, checks ground conditions, and reviews structural and drainage plans. You'll get a fixed-price quote within 48 hours covering excavation, removal, drainage, foundations, and prep — no hidden extras. All work is fully insured, building-regulation compliant, and completed by experienced groundworkers. Every project ends with a 10-year structural guarantee.
