Extension pulling away repairs in Cannock
Rear and side extensions are common across Cannock, and so is the crack where new meets old. Usually it reflects the two parts sitting on different foundations, and the first question is whether the gap is still opening.

Is Staffordshire prone to ground movement?
Cannock is in Staffordshire and takes in postcode districts WS11, WS12. About 86,000 people live there. We also take enquiries from nearby Great Wyrley (2 miles), Burntwood (4 miles) and Bloxwich (5 miles).
Parts of Staffordshire have clay that can shrink near trees in dry spells. Parts of Staffordshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Housing stock in Staffordshire: Potteries terraces, brick villas, inter-war semis and post-war estates.

Repair options we may recommend
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
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
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.
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.
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 will extension pulling away repairs cost in Cannock?
Guide prices for extension pulling away repairs in Cannock 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.

Is the ground in Staffordshire prone to subsidence?
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. Only an investigation can say why a particular building has moved.
Can I just fill the gap with mastic?
Mastic can keep water out short term, but it does not stop movement or reconnect the walls. If the gap reopens after filling, something is still moving. Photograph and measure it over a few months first, so an engineer can see the trend.
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.
