What should you know about the ground under Poulton-le-Fylde?
Poulton-le-Fylde (FY2, FY3, FY6) has around 20,000 residents and sits in Lancashire. We also take enquiries from nearby Blackpool (3 miles), Thornton-Cleveleys (3 miles) and Lytham St Annes (6 miles).
Parts of Lancashire have clay that can shrink near trees in dry spells. Parts of Lancashire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Lancashire: Stone and brick mill terraces, seaside villas in Blackpool and Lytham, and inter-war and post-war semis.
Methods for extension pulling away repairs
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
From first photo to finished repair
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.
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.
Symptoms that point to extension pulling away repairs
- Mastic or render at the joint repeatedly splitting open
- Daylight or draughts showing through the internal corner joint
- Extension roof flashing lifting off the original wall

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.
Frequently asked questions
How much will extension pulling away repairs cost in Poulton-le-Fylde?
Guide prices for extension pulling away repairs in Poulton-le-Fylde 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.
Do you cover Poulton-le-Fylde?
Yes. We take enquiries from across Poulton-le-Fylde, including FY2, FY3, FY6, and from nearby places such as Blackpool and Thornton-Cleveleys. Send photos for a free initial view and we will tell you what happens next.
Is the ground in Lancashire prone to subsidence?
Lancashire is mostly glacial till over sandstone and mudstone, with the Burnley and Accrington coalfield in the east and soft coastal and estuarine ground on the Fylde. Old mill and mine sites leave made ground in many towns. Only an investigation can say why a particular building has moved.
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.
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.
