Subsidence repairs in Pontypool
Cracks in a house in Pontypool are not always subsidence, and subsidence is not always serious. The first job is to find out what is moving and why, whether that is a leaking drain, a nearby tree or soft ground under shallow footings.

Is Gwent prone to ground movement?
With roughly 36,000 people, Pontypool spans postcode districts NP4 in Gwent. Nearby places we cover include Cwmbran (3 miles), Abertillery (4 miles) and Abercarn (5 miles).
Gwent has a mix of ground, with clay in some places and firmer rock in others. Historic coal workings are recorded beneath parts of Gwent, and a coal mining search is worth checking where movement is unexplained. What you mostly find across Gwent: valley terraces on steep hillsides, Victorian houses in Newport and Abergavenny, and post-war estates.
What to expect when we carry out subsidence repairs
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.
Deal with the cause
Drains are repaired, vegetation is managed on the engineer’s advice, or a foundation scheme is designed if nothing else will work. Where monitoring is recommended, readings run for several months to show the movement has stopped.

Repair options we may recommend
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
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
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.
Your subsidence repairs questions
How much will subsidence repairs cost in Pontypool?
Guide prices for subsidence repairs in Pontypool 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 cover Pontypool?
Yes, Pontypool is covered, along with postcode districts NP4. We also cover nearby Cwmbran and Abertillery.
Is the ground in Gwent prone to subsidence?
The valleys of Blaenau Gwent, Torfaen and Islwyn lie on the South Wales coalfield with extensive historic workings and spoil tips, while Newport and Monmouthshire have Mercia Mudstone, alluvium and Old Red Sandstone. Only an investigation can say why a particular building has moved.
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.
Does subsidence always need underpinning?
No, most subsidence is repaired without underpinning. When a leaking drain is fixed or nearby vegetation is managed, the ground usually stabilises and the house needs only crack repairs. Foundation work is kept for movement that continues after the cause has gone.
