Extension pulling away repairs in Whitehaven
For many Whitehaven homes, the extension was added decades after the house was built, on concrete that never matched the original footings. Where that difference causes movement, a designed movement joint or a deeper foundation is the usual fix.

What is the ground like in Cumbria?
Whitehaven is in Cumbria and takes in postcode districts CA28. About 23,000 people live there. If you are just outside Whitehaven, we also cover Workington (7 miles).
Clay shrinkage is less of a concern in Cumbria, so other causes such as drains, poor footings or older walls are checked first. Parts of Cumbria lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Cumbria: Stone-built terraces and farmhouses, sandstone town houses in Carlisle and post-war estates.

How we usually approach 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
What happens during extension pulling away repairs, step by step?
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.
Questions about extension pulling away repairs in Whitehaven
How much should I budget for extension pulling away repairs in Whitehaven?
Guide prices for extension pulling away repairs in Whitehaven start from about £575 per junction, including VAT, on North West 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 Whitehaven?
Yes, Whitehaven is covered, along with postcode districts CA28. We also cover nearby Workington.
Why do houses in Cumbria crack?
Cumbria's ground is largely hard rock and glacial deposits, with the West Cumberland coalfield around Whitehaven and Workington where historic coal workings are recorded. Stone walls and older lime mortars feature in much of the housing. 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.
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.
