Is Nottinghamshire prone to ground movement?
Newark-on-Trent (NG24) has around 43,000 residents and sits in Nottinghamshire. If you are just outside Newark-on-Trent, we also cover Grantham (13 miles), Arnold (14 miles) and Nottingham (16 miles).
Parts of Nottinghamshire have clay that can shrink near trees in dry spells. Parts of Nottinghamshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Nottinghamshire: Brick terraces in former colliery towns, Victorian villas in Nottingham, and inter-war and post-war semis.
Methods for extension pulling away repairs
Underpinning the extension
If the extension is still dropping because its footings are too shallow or on poor ground, they are taken deeper by mass concrete, beam-and-base or mini-piles. The engineer designs the scheme, and the junction is repaired once the new foundation is in.
Best for: Active movement from shallow footings, roots or soft ground
Movement joint and making good
Where some seasonal movement is expected to continue, the junction is formed into a proper flexible movement joint with a compressible filler and sealant, so the two parts can move without cracking. Flashings and internal finishes are detailed to suit.
Best for: Minor ongoing movement that does not threaten the structure
From first photo to finished repair
Find what is moving
An independent chartered structural engineer can inspect, and we can arrange one. A drain survey under the extension, a trial pit at its footing and tell-tale monitoring across the joint are common checks before choosing the repair.
Choose the fix
The engineer decides between ties, a movement joint or underpinning. We confirm a fixed price in writing once the repair is specified, covering the junction, flashings, internal finishes and any foundation work.
Finish and hand over
Internal corners are replastered, skirtings and coving refixed, and doors or windows in the extension eased where the movement affected them. Records of the repair and any approvals are passed to you.
Symptoms that point to extension pulling away repairs
- Extension roof flashing lifting off the original wall
- Mastic or render at the joint repeatedly splitting open

Rules for extension pulling away repairs 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.
Frequently asked questions
How much will extension pulling away repairs cost in Newark-on-Trent?
Guide prices for extension pulling away repairs in Newark-on-Trent start from about £590 per junction, 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 Newark-on-Trent?
Yes. We take enquiries from across Newark-on-Trent, including NG24, and from nearby places such as Grantham and Arnold. Send photos for a free initial view and we will tell you what happens next.
Is the ground in Nottinghamshire prone to subsidence?
West Nottinghamshire around Mansfield, Hucknall and Kirkby-in-Ashfield is on the Coal Measures with a long mining history, while Nottingham sits on sandstone with Mercia Mudstone clay to the south and east. Only an investigation can say why a particular building has moved.
Can a drain under my extension cause it to move?
Yes, a cracked or displaced drain beneath or beside an extension can soften clay or wash away fine soil. A CCTV drain survey usually finds it. Repairing the drain is often the first and most important step before any repair to the walls.
Will my extension need underpinning?
Often not. Many separating extensions are fixed by repairing a drain, tying the junction or forming a movement joint. Underpinning is for extensions that keep dropping because their footings are too shallow or the ground beneath is poor, as shown by monitoring.
