Extension pulling away repairs in Rhyl
An extension pulling away from a Rhyl 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.

How we usually approach 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
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.
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.
What to look for before calling about 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

Questions about extension pulling away repairs in Rhyl
What is the price of extension pulling away repairs in Rhyl?
Guide prices for extension pulling away repairs in Rhyl start from about £550 per junction, including VAT, on Wales 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 Rhyl?
Yes, Rhyl is covered, along with postcode districts LL18. We also cover nearby Prestatyn and Abergele.
Does the ground around Rhyl cause cracking?
The North Wales coalfield runs beneath parts of Wrexham and Flintshire, where historic workings are recorded, while the coast and vale have glacial clays and the hills are older hard rock. 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.
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.
