What is the ground like in Gwynedd?
Bangor (LL57, LL59) has around 18,000 residents and sits in Gwynedd. Neighbouring towns we cover: 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. Typical buildings in Gwynedd: Slate and stone terraces, chapels and cottages, Victorian seaside houses and post-war estates.

Which repair method suits a home in Bangor?
Gable restraint straps
Steel straps are fixed across at least three rafters or ceiling joists, with blocking packed tight between the last timber and the wall, then turned down and fixed into the gable masonry. They are fitted from inside the loft, so the outside of the house is usually untouched.
Best for: Sound gables with no connection to the roof
Rebuilding the top of the gable
If the apex has leaned, cracked right through or lost its bond, the roof covering is stripped back along the verge, the upper courses are taken down to sound brickwork and the gable is rebuilt with straps and ties built in. Original bricks are reused where they are in good condition.
Best for: Gables leaning or cracked beyond tying back
What happens when we carry out gable end wall repairs in Bangor?
Check from the loft
Much of the diagnosis happens in the roof space. Photos of where the rafters, purlins and joists meet the gable, plus outside shots of the verge, tell us a great deal before we visit.
Measure the lean
On site we plumb the gable, look for cracks at ceiling line and apex, and check the chimney and verge. Large movement or an unclear cause is a job for an engineer, whom we can bring in for you.
Strap, tie or rebuild
Straps and blocking are fitted at the spacing required, ties drilled and fixed, or the upper gable rebuilt course by course with restraint built in. Roofing along the verge is relaid and bedded or dry-fixed.
Rules for gable end 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.
Gable end wall repairs in Bangor: questions and answers
How much should I budget for gable end wall repairs in Bangor?
Guide prices for gable end wall repairs in Bangor start from about £920 per gable, 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. We take enquiries from across Bangor, including LL57, LL59, and from nearby places such as Llangefni and Caernarfon. Send photos for a free initial view and we will tell you what happens next.
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.
What are gable restraint straps?
Gable restraint straps are steel straps that tie the gable wall to the roof timbers so it cannot move outward. They run across several rafters or joists with blocking between, then turn down to fix into the masonry. Modern houses have them built in.
How long does gable restraint last?
Properly fixed galvanised or stainless straps should last for the life of the roof in a dry loft. What matters is that they are fixed into sound masonry and solid timber with tight blocking. A strapped gable can still be weakened by failed wall ties or poor pointing, so those are checked too.
