Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!
Dmitry
Highly recommend. These guys did a fantastic job of constructing our pergola and decking. Very hardworking and reliable. The job was completed in the time frame agreed and to a very high standard. We would 100% use them again.

Underpinning, piling and foundation construction – Rated People
What can a local foundation, underpinning and piling specialist help with?
Ensure your home, extension, or new build stands on a safe, compliant structure by hiring experienced groundworkers and structural engineers. Look out for local foundation and piling specialists who:
- Perform trial hole excavations and site surveys to assess ground stability, water table levels, and clay content before pouring concrete.
- Excavate and install traditional strip footings and trenchfill foundations for single-storey or two-storey home extensions.
- Remedy active subsidence, wall cracking, and defective footings using mass concrete underpinning or modern pile-and-beam techniques.
- Install mini-piling, screw piles, or piled raft foundations in restricted-access plots, clay-heavy soils, or close to mature tree roots.
- Work alongside chartered structural engineers (IStructE registered) to ensure all load-bearing calculations meet local Building Control sign-offs.
A local specialist understands soil profiles and local geology in your region, ensuring they recommend the most cost-effective and structurally sound foundation method for your plot.

How much do foundations, underpinning and piling cost?
The overall cost of groundwork depends on ground conditions, site accessibility, excavation depth, and the specific structural engineering method required. Basic extension trenching is significantly less expensive than specialised mini-piling or deep underpinning.
For standard UK residential projects:
- Trench excavation: Typically costs £7 to £15 per square metre (excluding site clearance and soil disposal).
- Standard concrete foundations (strip / trench fill): Pouring concrete and building subterranean block work generally costs £40 to £80 per square metre.
- Mass concrete underpinning: Stabilising defective footings typically ranges from £1,000 to £2,000 per linear metre, depending on dig depth and soil stability.
- Piling / mini-piling: Engineered piling systems (such as pile and beam) generally cost 2 to 3 times more than standard concrete footings, typically starting from £2,500 to £5,000+ per project for specialist rig equipment and steel pile insertion.

What is the difference between underpinning and piling?
Choosing between underpinning and piling depends on whether you are repairing existing, defective foundations or constructing a new structure on unstable ground:
- Underpinning: Used primarily to repair or strengthen existing buildings suffering from subsidence, cracked walls, or increased load requirements (such as adding a loft or second floor). The standard mass concrete method involves excavating deep pits directly beneath defective footings in sections and filling them with reinforced concrete to extend the foundation to stable soil.
- Piling: Primarily used for new construction or on sites where upper soil layers are too weak to support standard footings. It involves driving or screwing long, slender columns of steel, concrete, or timber deep into the earth until they reach dense rock or load-bearing strata. Techniques like screw piling or pile-and-beam are also used for underpinning when site access is severely restricted.
- Key comparison: Underpinning directly deepens existing footings, whereas piling transfers structural weight past soft upper soil into deeper, firm ground using heavy machinery or mini-rigs.
Investing in qualified groundwork tradespeople protects your property's structural integrity, prevents future ground movement, and ensures your project receives essential Building Control approval.
Securing the base of your home brings lifelong stability and protects your property's resale value. Whether you are building an extension or fixing subsidence cracks, a local groundwork expert can get it sorted safely.

Other foundations, underpinning and piling FAQs
How do I know if my house needs underpinning?
Classic signs of foundation failure include severe diagonal cracks on internal or external walls (especially those wider than 6mm / 1/4 inch), doors and windows sticking or pulling away from frames, leaning chimneys, and visibly sloping floors. A structural engineer can confirm whether active movement requires underpinning.
Do I need planning permission for underpinning or laying foundations?
Laying new foundations for an extension or new build will be covered under your overall planning permission and mandatory Building Regulations sign-off. Remedial underpinning on an existing home usually does not require planning permission unless the property is a listed building, though it always requires Building Regulations approval.
What qualifications should my groundwork or structural team hold?
Your structural design and load calculations should be provided by a chartered engineer registered with the Institution of Structural Engineers (IStructE) or Institution of Civil Engineers (ICE). Your groundworkers should hold proven site experience, valid Public Liability Insurance, and professional indemnity cover for engineered designs.
