How we usually approach subsidence repairs
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
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
What happens during subsidence repairs, step by step?
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.
Rules for subsidence repairs in Northern Ireland
In Northern Ireland, the Building Regulations (Northern Ireland) 2012 apply and the council’s building control service approves structural work such as underpinning; minor like-for-like repairs usually need no approval. The Party Wall Act does not apply in Northern Ireland, so work to shared walls depends on deeds and agreement with neighbours.
Questions about subsidence repairs in Newtownards
How much should I budget for subsidence repairs in Newtownards?
Guide prices for subsidence repairs in Newtownards start from about £2,200 per property, including VAT, on Northern Ireland 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 Newtownards?
We do. Newtownards and the surrounding area are covered, including nearby Bangor and Holywood. A free initial assessment from your photos is the first step.
Why do houses in County Down crack?
County Down is mostly drumlin till over older rock and granite in the Mournes, with soft estuarine ground around Belfast Lough and Strangford. Only an investigation can say why a particular building has moved.
Will past subsidence affect my home insurance?
It can, because insurers ask about previous subsidence at renewal or when you switch. Staying with the insurer who handled a claim is often simplest. Answer any new insurer’s questions honestly and keep the repair records, which show the problem was dealt with.
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.
