Subsidence repairs in Pwllheli
Tapered cracks around the windows or doors of a Pwllheli home are worth taking seriously without assuming the worst. In most cases the cause can be found and removed, and the house then needs crack stitching and making good rather than new foundations.

Why does the ground in Gwynedd matter for subsidence repairs?
Postcode districts LL53 cover Pwllheli, a Gwynedd town of about 4,000 people. Nearby, we also cover Caernarfon (18 miles).
Shrinkable clay is less common in Gwynedd than in south-east England. 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.

Find the cause
An independent chartered structural engineer inspects the house and, where needed, arranges a drain survey, trial pits or soil tests. We can arrange the engineer. The aim is to know what is moving, and why, before money goes on repairs.
Written quote
We price the agreed repair and confirm a fixed price in writing once it is specified. If there is an insurance claim, we can price to the loss adjuster’s or engineer’s schedule instead of our own scope.
Repairs and making good
Cracks are stitched and repointed outside, plaster is renewed along the crack lines inside, and sticking doors are eased. Where the work needs it, we deal with building control and hand over the paperwork.
Symptoms that point to subsidence repairs
- A gap opening between the skirting board and the floor
- Fresh cracks showing on both the inside and outside of one wall
- Cracks that open in summer and partly close again in winter

Methods for subsidence repairs
Crack stitching and making good
Once movement has stopped, cracked brickwork is cut along the bed joints, stainless helical bars are bonded in to tie the wall together, and the joints are repointed to match. Inside, plaster is renewed along the crack line before redecoration.
Best for: Category 1 to 3 cracking in walls that are otherwise sound
Foundation strengthening
Where the ground cannot be made stable, the load is carried down to firmer soil by underpinning, a beam-and-base scheme, mini-piles or resin injection, depending on the soil and access. It is designed by an engineer and is the exception, not the rule.
Best for: Ongoing movement where removing the cause has not worked
Rules for subsidence 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
What is the price of subsidence repairs in Pwllheli?
Guide prices for subsidence repairs in Pwllheli start from about £2,300 per property, 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 subsidence repairs in Pwllheli?
Yes. We take enquiries from across Pwllheli, including LL53, and from nearby places such as Caernarfon. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Pwllheli cause cracking?
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.
How do I know if cracks are subsidence?
Subsidence cracks are usually tapered, run diagonally from door and window corners, and show on both faces of the wall. Fine vertical cracks in new plaster are more often shrinkage. An engineer’s inspection, sometimes with monitoring, is the reliable way to tell.
Can I sell a house that has had subsidence?
Yes, though buyers and lenders will want paperwork. Keep the engineer’s report, monitoring results, the repair specification and any building control sign-off. A repaired house shown to be stable is far easier to sell than one with an open problem.
