Underpinning in Kettering
Underpinning a house in Kettering starts with proof that it is needed, not with a digger. An independent engineer looks at the monitoring and ground investigation, then chooses between mass concrete, beam-and-base or mini-piles for that particular wall and soil.

What should you know about the ground under Kettering?
Kettering, Northamptonshire: about 57,000 residents across postcode districts NN15, NN16. We also take enquiries from nearby Wellingborough (7 miles), Corby (7 miles) and Rushden (9 miles).
Much of Northamptonshire sits on clay that shrinks in dry summers and swells in wet winters. Historic ironstone working has left disturbed ground in places. What you mostly find across Northamptonshire: ironstone and limestone cottages, Victorian terraces in Northampton and Kettering, and new-town estates in Corby.
Repair options we may recommend
Mass concrete underpinning
The traditional method. Short sections under the wall are dug out in a set sequence, usually about a metre at a time, and filled with concrete before the next section is opened. It suits moderate depths and good access, and it needs little specialist plant.
Best for: Shallow failures on firm ground found at moderate depth
Mini-piled underpinning
Small-diameter piles are driven or bored down to firm ground and linked by a reinforced beam or needles that pick up the wall. Compact rigs fit through narrow access, and the method reaches depths that would be impractical to excavate by hand.
Best for: Deep soft ground, tree roots, or restricted access
What to expect when we carry out underpinning
Engineer’s investigation
An independent chartered structural engineer studies the monitoring results, trial pits and soil tests, then decides whether underpinning is needed and which method suits. We can arrange the engineer if you do not already have one.
Fixed written price
With the design in hand we confirm a fixed price in writing, setting out the method, the length of wall, access arrangements and the making good. For insurance work we can price to the loss adjuster’s or engineer’s schedule.
Crack repairs and handover
Once the new foundation has cured, cracks are stitched and repointed, inside walls are made good, and paths or patios disturbed by the dig are reinstated. You receive the building control completion paperwork for your records.

Rules for underpinning in England
In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.
Your underpinning questions
How much will underpinning cost in Kettering?
Guide prices for underpinning in Kettering start from about £980 per metre of wall, including VAT, on East Midlands rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Kettering?

Is the ground in Northamptonshire prone to subsidence?
Northamptonshire sits largely on Lias clay and Jurassic ironstones and limestones, with historic ironstone quarrying around Corby and Kettering. The clay vales are prone to shrinkage near trees. Only an investigation can say why a particular building has moved.
Does my house really need underpinning?
Often not, because most subsidence is fixed by repairing drains or managing trees and then repairing the cracks. Underpinning is justified when monitoring shows movement continuing after the cause has been dealt with, or when the ground itself is unsuitable. An independent engineer should make that call.
Do I need to tell my neighbours about underpinning?
In England and Wales you usually do. Underpinning a party wall normally needs two months’ notice, and excavating near a neighbour’s foundations needs one month’s notice under the Party Wall etc. Act 1996. Scotland and Northern Ireland have no equivalent Act, but agreeing the work in writing still helps.
