Extension pulling away repairs in Kenilworth
The ground under Kenilworth and Warwickshire varies street by street, and extensions built on shallower footings feel those differences first. A trial pit and a drain survey usually tell an engineer how the extension’s foundation is coping.

Is Warwickshire prone to ground movement?
Kenilworth, Warwickshire: about 22,000 residents across postcode districts CV8. We also take enquiries from nearby Warwick (5 miles), Coventry (5 miles) and Leamington Spa (5 miles).
Parts of Warwickshire have clay that can shrink near trees in dry spells. Parts of Warwickshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Warwickshire: Regency houses in Leamington Spa, timber-framed buildings in Stratford and Warwick, and brick terraces and estates in the north.
Repair options we may recommend
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
What to expect when we carry out extension pulling away repairs
Show us the junction
Send photos of the crack outside, the internal corner and any flashing above, with a measure for scale. We give a free initial assessment and an initial view on whether the gap is likely old or still opening.
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.
Repair the junction
Drains are repaired first if they are leaking. The joint is then tied, formed as a movement joint or rebuilt after underpinning, with roof flashings reset so the junction stays watertight. Building control is handled where needed.

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.
Your extension pulling away repairs questions
How much should I budget for extension pulling away repairs in Kenilworth?
Guide prices for extension pulling away repairs in Kenilworth start from about £600 per junction, including VAT, on West Midlands rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Kenilworth?
Yes, Kenilworth is covered, along with postcode districts CV8. We also cover nearby Warwick and Coventry.
Why do houses in Warwickshire crack?
Much of Warwickshire is Mercia Mudstone and Lias clay, with the Warwickshire coalfield under Nuneaton and Bedworth in the north. Clay soils near trees can shrink in dry summers. Only an investigation can say why a particular building has moved.
Who is responsible if a recent extension is moving?
If the extension is recent, the original builder, the designer or building control records may be relevant, and you may have rights against the builder. Gather the plans, completion certificate and contract. Insurance often excludes defects in new construction, so check your policy.
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.
