Why does the ground in Staffordshire matter for extension pulling away repairs?
North Staffordshire around Stoke-on-Trent, Newcastle-under-Lyme and Kidsgrove, and the Cannock Chase area, lie on coalfields with recorded workings. Much of the rest of the county is Mercia Mudstone and glacial clay.
Parts of Staffordshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across Staffordshire: Potteries terraces, brick villas, inter-war semis and post-war estates.
From first photo to finished repair
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.
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.
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
- Patio doors or windows in the extension starting to bind
- Mastic or render at the joint repeatedly splitting open
- Daylight or draughts showing through the internal corner joint
- A vertical crack or gap where the extension meets the house

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
Junction crack repair with stainless ties
The open joint is cut out, stainless ties or helical bars are fixed across it into both the old and new masonry, and the joint is repointed or rendered to match. Inside, the corner is replastered. This suits extensions that moved once and have since stopped.
Best for: Settled extensions with a stable gap at the junction
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
Do you need approval 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
Why do houses in Staffordshire crack?
North Staffordshire around Stoke-on-Trent, Newcastle-under-Lyme and Kidsgrove, and the Cannock Chase area, lie on coalfields with recorded workings. Much of the rest of the county is Mercia Mudstone and glacial clay. Parts of Staffordshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Only an investigation on site can say why a particular building has moved.
How much will extension pulling away repairs cost in Staffordshire?
On West Midlands rates, extension pulling away repairs starts from about £600 per junction, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
What is a movement joint?
A movement joint is a deliberate, flexible break in a wall that lets two parts of a building move slightly without cracking. It is filled with a compressible material and sealed. At an extension junction it can replace a rigid joint that keeps cracking.
Why is my extension pulling away from my house?
Usually because the extension and the house sit on different foundations that react differently to the ground. Shallow extension footings, leaking drains under the extension, nearby roots and weak tie-ins between old and new walls are the common causes.
Is it normal for an extension to crack at the join?
A fine crack at the junction is fairly common, especially in the first few years as a new extension settles. It becomes a concern when the gap is widening, tapering, letting in water or matched by sticking doors and sloping floors. Those signs point to continuing movement.
