What is the ground like in Gwynedd?
With roughly 18,000 people, Bangor spans postcode districts LL57, LL59 in Gwynedd. We also take enquiries from nearby Llangefni (8 miles), Caernarfon (9 miles) and Llandudno (14 miles).
Most of Gwynedd is on firmer ground than the clay belts of the south-east. Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. Housing stock in Gwynedd: Slate and stone terraces, chapels and cottages, Victorian seaside houses and post-war estates.
From first photo to finished repair
Assess the bow
We look at where the wall bows, how far it is out of plumb and how the floors and roof meet it. Photographs from your phone held flat against the wall often show the shape clearly before anyone visits.
Decide restrain or rebuild
If the wall is badly out of plumb, has bricks crushing or follows removed internal walls, we recommend an engineer, and can arrange one. Their view sets whether restraint is enough or a section needs rebuilding.
Close up and make good
Boards are relaid, plaster and outside fixings made good, and cracked joints repointed. You receive a record of the restraint positions, which helps if you sell or if an engineer needs to check the wall again later.
Symptoms that point to bowing wall repairs
- Gutters or the roof edge no longer lining up with the wall
- Internal plaster cracks where a wall meets the ceiling
- Horizontal cracking at first-floor or ceiling level

Methods for bowing wall repairs
Restraint ties into the floor
Stainless restraint ties are drilled through the wall and fixed into the floor joists or into blocking between them. Where joists run parallel, noggins are fitted across several joists so the tie has something solid to hold. A neat plate or a buried fixing is left on the outside face.
Best for: Walls bowing at floor level where joists run alongside
Stitching a delaminating wall
Where the layers of a solid wall have separated, long stainless ties are drilled in from the face and bonded into the inner layer to bind the wall together again. This is often combined with restraint ties, so the wall is both reconnected through its thickness and tied back to the structure.
Best for: Solid walls where the outer layer has pulled away
Rules for bowing wall repairs in Wales
In Wales, the Welsh version of the Building Regulations applies. Underpinning and other work that alters or strengthens the structure needs building control approval and inspection; like-for-like repairs often do not. The Party Wall etc. Act 1996 applies to work on party walls and excavation close to a neighbour’s foundations.
Frequently asked questions
How much should I budget for bowing wall repairs in Bangor?
Guide prices for bowing wall repairs in Bangor start from about £920 per wall, including VAT, on Wales 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 Bangor?
Yes, Bangor is covered, along with postcode districts LL57, LL59. We also cover nearby Llangefni and Caernarfon.
Why do houses in Gwynedd crack?
Gwynedd and Anglesey are mostly hard rock with glacial deposits, so clay shrinkage is uncommon. Historic slate quarrying and metal mining have left tips and workings in places. Only an investigation can say why a particular building has moved.
Can a bowing wall be pushed back straight?
Usually not. Masonry rarely returns to plumb without cracking, so the normal aim is to stop further movement and leave the wall where it is. If the bow is too great to accept, that section is rebuilt rather than forced back.
Does a bowing wall need an engineer?
Often it does, especially if the bow is large, growing or linked to removed internal walls or chimney breasts. Small, long-standing bows can sometimes be restrained to a standard detail. Where the repair needs an engineer’s design or sign-off, we can arrange an independent chartered structural engineer.
