Extension pulling away repairs in Eastbourne
An extension pulling away from a Eastbourne house is often a drain problem, a shallow footing or a missing tie-in, rather than a failing building. Finding out which applies decides whether the fix is a junction repair or new foundations.

What should you know about the ground under Eastbourne?
Postcode districts BN20, BN21, BN23 cover Eastbourne, a East Sussex town of about 100,000 people. Neighbouring towns we cover: Hailsham (7 miles), Seaford (8 miles) and Bexhill-on-Sea (10 miles).
East Sussex is one of the parts of the UK where clay soils are most likely to move with the seasons. Ground movement here is more often linked to soils, drains and trees than to mining. Typical buildings in East Sussex: Regency and Victorian terraces on the coast, Wealden timber-framed houses, and inter-war bungalows and semis.
How we usually approach extension pulling away repairs
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
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
What happens during extension pulling away repairs, step by step?
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.
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.
What to look for before calling about extension pulling away repairs
- A vertical crack or gap where the extension meets the house
- Mastic or render at the joint repeatedly splitting open
- Daylight or draughts showing through the internal corner joint

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 Eastbourne
What is the price of extension pulling away repairs in Eastbourne?
Guide prices for extension pulling away repairs in Eastbourne start from about £670 per junction, including VAT, on South East 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 Eastbourne?
Yes. We take enquiries from across Eastbourne, including BN20, BN21, BN23, and from nearby places such as Hailsham and Seaford. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Eastbourne cause cracking?
Inland East Sussex is Weald Clay and Wealden sands, while the South Downs and the coast around Brighton and Eastbourne are chalk. The Weald Clay areas are prone to shrink-swell movement near trees. Only an investigation can say why a particular building has moved.
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.
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.
