Is Clwyd prone to ground movement?
We cover Mold and its postcode districts CH7, part of Clwyd, with a population of roughly 10,000. Nearby places we cover include Buckley (2 miles), Connah's Quay (5 miles) and Flint (5 miles).
Clwyd has a mix of ground, with clay in some places and firmer rock in others. Parts of Clwyd lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Typical buildings in Clwyd: Brick colliery terraces, seaside villas in Rhyl and Colwyn Bay, and post-war estates.
What happens when we carry out subsidence repairs in Mold?
Send photos or call
Send photos of the cracks with a coin or tape for scale, and say when you first noticed them. We give a free initial assessment and suggest whether an engineer, a drain survey or your insurer comes first.
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.
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.
Signs you may need subsidence repairs
- A gap opening between the skirting board and the floor
- Cracks that open in summer and partly close again in winter
- Doors and windows that start to stick or no longer close

Which repair method suits a home in Mold?
Remove the cause, then repair
Most subsidence is dealt with this way. The drain is repaired or the vegetation managed, the house is watched to confirm it has stabilised, and then the cracks are stitched, repointed and made good inside. It is the least disruptive route and usually the cheapest.
Best for: Clay movement or drain leaks where the cause can be removed
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
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.
Subsidence repairs in Mold: questions and answers
What is the price of subsidence repairs in Mold?
Guide prices for subsidence repairs in Mold 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 Mold?
Yes, Mold is covered, along with postcode districts CH7. We also cover nearby Buckley and Connah's Quay.
Does the ground around Mold 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.
Should I cut down the tree near my house?
Not without advice, because felling a mature tree on clay can make things worse. As the roots stop drawing water, the clay swells and can lift the foundations, which is called heave. Pruning or staged removal may be advised instead. Check whether the tree is protected.
Do you need to visit before giving a price?
Not at first. We give a free initial assessment from your photos or a call, and a no-obligation written quote once the scope is clear. A fixed price follows in writing once the repair is specified, which normally needs a survey.
