Is North Yorkshire prone to ground movement?
We cover Yarm and its postcode districts TS15, TS16, TS17, part of North Yorkshire, with a population of roughly 19,000. We also take enquiries from nearby Thornaby-on-Tees (3 miles), Stockton-on-Tees (5 miles) and Middlesbrough (7 miles).
North Yorkshire has a mix of ground, with clay in some places and firmer rock in others. Parts of North Yorkshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across North Yorkshire, most homes are stone cottages, Georgian and Victorian houses in York and Harrogate, and brick terraces on Teesside.
What happens when we carry out extension pulling away repairs in Yarm?
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.
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.
Signs you may need extension pulling away repairs
- Floor level dropping where the extension and house floors meet

- Mastic or render at the joint repeatedly splitting open

Which repair method suits a home in Yarm?
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
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.
Extension pulling away repairs in Yarm: questions and answers
What is the price of extension pulling away repairs in Yarm?
Guide prices for extension pulling away repairs in Yarm start from about £570 per junction, including VAT, on Yorkshire and the Humber rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you carry out extension pulling away repairs in Yarm?
We do. Yarm and the surrounding area are covered, including nearby Thornaby-on-Tees and Stockton-on-Tees. A free initial assessment from your photos is the first step.
Does the ground around Yarm cause cracking?
North Yorkshire ranges from limestone dales and moors to clays and glacial deposits in the Vale of York, with the Selby coalfield in the south and ironstone workings in Cleveland. Teesside has areas of soft and made ground. 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.
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.
