Homeowners choose us for tidy workmanship, dependable scheduling and a finish that’s ready for blockwork or slab construction.
We know the access and parking realities on Downham’s residential streets and plan deliveries, skips and concrete pours accordingly.

Costs depend on foundation type (strip, pad or raft), depth, access, spoil removal and whether reinforcement or engineering is required. As a guide, small pad bases for posts or a garden room can start from £800–£2,000. Strip foundations for an extension are commonly £3,000–£8,000, while a reinforced raft foundation may be £6,000–£15,000+. We’ll survey your Downham site and provide a detailed, itemised estimate.
Most domestic foundation jobs take 2–7 working days from excavation to pour, with curing time afterwards before heavy loading. A few pads may be completed in 1–2 days, while deeper strip foundations or a raft can take a week or more. Timescales are affected by access in BR1, skip placement, ground conditions, Building Control inspection timing, and weather. We programme the work to minimise downtime for your builder.
Foundations themselves usually fall under Building Regulations rather than planning permission, but the structure they support (extension, outbuilding, wall) may require planning depending on size and location. Many garden projects are permitted development, yet rules can change with previous extensions, boundary positions and drainage. We’ll advise what typically applies in Lewisham and help you prepare for Building Control checks. If planning is needed, we’ll coordinate with your designer or builder.
We provide a 10-year warranty on our foundation workmanship, covering issues caused by installation defects such as incorrect levels, inadequate compaction, or poor concrete placement. Where designs are engineer-led, we build strictly to the specification, including reinforcement, thickness and bearing requirements. The warranty does not cover movement caused by external factors outside our control (for example, major leaks or tree-related subsidence), but we’ll always investigate concerns promptly and fairly.
We offer strip foundations for load-bearing walls, pad foundations for point loads (posts and piers), and raft foundations where ground conditions or layouts benefit from a full slab. Options include reinforced concrete with rebar mesh or cages, wall footings for retaining or boundary walls, and deeper foundations where required. We’ll recommend the best approach after assessing your Downham site, intended loads and access, and we can liaise with your structural engineer to finalise the design.
