Which repair method suits a home in Abergavenny?
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
What happens when we carry out subsidence repairs in Abergavenny?
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.
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.
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.

Subsidence repairs in Abergavenny: questions and answers
What is the price of subsidence repairs in Abergavenny?
Guide prices for subsidence repairs in Abergavenny 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 Abergavenny?
Yes. We take enquiries from across Abergavenny, including NP7, and from nearby places such as Abertillery and Pontypool. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Abergavenny cause cracking?
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.
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.
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.
