Is Essex prone to ground movement?
With roughly 21,000 people, Harwich spans postcode districts CO12 in Essex. Neighbouring towns we cover: Felixstowe (3 miles), Walton-on-the-Naze (7 miles) and Ipswich (10 miles).
Essex 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. Housing stock in Essex: Victorian terraces, 1930s semis and bungalows, and large post-war new-town estates in Basildon and Harlow.
Which repair method suits a home in Harwich?
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 happens when we carry out extension pulling away repairs in Harwich?
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.
Signs you may need extension pulling away repairs
- Daylight or draughts showing through the internal corner joint
- Mastic or render at the joint repeatedly splitting open
- A vertical crack or gap where the extension meets the house

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 Harwich: questions and answers
What is the price of extension pulling away repairs in Harwich?
Guide prices for extension pulling away repairs in Harwich start from about £630 per junction, including VAT, on East of England 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 Harwich?
We do. Harwich and the surrounding area are covered, including nearby Felixstowe and Walton-on-the-Naze. A free initial assessment from your photos is the first step.
Does the ground around Harwich cause cracking?
London Clay covers much of south and central Essex and boulder clay much of the north, making it one of the counties most affected by clay shrinkage in dry summers. Street and garden trees close to houses add to the risk. 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.
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.
