If you’re planning an extension, garden room or structural landscaping, the foundation is where the job is won or lost. We deliver engineered concrete bases across KT3, with regular work near New Malden High Street and Manor Park. Our team handles strip foundations, pad foundations, raft foundations and wall footings, matched to the build and ground conditions. You get a tidy site, accurate levels and a pour that’s ready for the next trade.
New Malden’s mix of 1930s semis, Edwardian houses and modern apartments means no two plots behave the same. Side access can be tight around Raynes Park and Motspur Park, while rear gardens often need careful spoil removal and protection of existing paving. We design concrete foundations New Malden area homeowners can rely on, whether you’re underpinning a new wall line or supporting a heavier structure. Every job is set out precisely to avoid costly changes later.
We start with a site visit, levels and a practical foundation recommendation, then coordinate excavation, formwork and reinforcement. Where required, we work to engineer details and Building Control expectations, including depth, concrete specification and steel placement. You’ll receive clear scope, staged inspections and photo updates, with safe working practices throughout. Homeowners choose us for concrete foundations in Royal Borough of Kingston upon Thames because we keep programmes moving and finishes accurate.
Across the Royal Borough of Kingston upon Thames, ground conditions can vary between made-up ground, clay and mixed subsoils, so we don’t assume a one-size depth. Parking and access around New Malden High Street can affect muck-away and concrete deliveries, so we plan skips, pump access and pour timing carefully. For 1930s semis and Edwardian plots, we protect boundaries, manage party-wall sensitivities, and keep excavations safe and supported. The result is a foundation that suits the property and the site constraints.
Rated 4.9/5 from over 280 verified reviews
Costs depend on foundation type, depth, access and how much spoil needs removing. As a guide, small pad foundations might start around £900–£2,000, while strip foundations for a typical extension are often £3,500–£9,000. Raft foundations and deep/reinforced solutions can range from £8,000–£20,000+. We provide a detailed breakdown after a site visit in KT3.
Most domestic foundations take 2–5 working days from excavation to pour, with an additional curing period before heavy loading. Larger extensions or raft foundations may take 1–2 weeks depending on steelwork, formwork and inspections. Timescales are affected by access (wheelbarrow runs vs mini-digger), weather, depth requirements, and Building Control sign-off points. We schedule deliveries and inspections to minimise downtime.
Concrete foundations themselves usually fall under the wider project, and many domestic works are permitted development, but Building Regulations approval is commonly required for structural foundations. If you’re close to boundaries, affecting drainage, or building near trees, extra checks may apply. We can liaise with your designer/engineer and ensure Building Control inspections are booked at the right stages. We’ll also flag any local constraints early.
Yes. We back our foundation workmanship with a 10-year warranty, covering defects caused by installation issues such as incorrect levels, poor compaction, or reinforcement not installed to the agreed specification. The warranty applies when the foundations are used as designed and not altered by third parties. We also keep records and photos of key stages to support Building Control and give you peace of mind.
We install strip, pad and raft foundations, plus wall footings and reinforced options where loads or ground conditions demand it. Concrete specifications can vary (e.g., stronger mixes, sulphate-resistant concrete) and reinforcement can include mesh or rebar cages to engineer detail. We’ll advise on depth, width, steel placement and pour method (chute or pump) based on your build and access in New Malden.
