Subsidence repairs in Bangor
Subsidence in Bangor, as anywhere in County Down, usually comes back to the ground beneath the footings: clay drying out, a drain leaking or roots taking water. Knowing which applies decides whether the repair is a few days of crack work or a longer foundation scheme.

Is County Down prone to ground movement?
Postcode districts BT19, BT20 cover Bangor, a County Down town of about 61,000 people. We also take enquiries from nearby Newtownards (5 miles), Holywood (6 miles) and Downpatrick (23 miles).
Shrinkable clay is less common in County Down than in south-east England. Ground movement here is more often linked to soils, drains and trees than to mining. Across County Down, most homes are Victorian seaside houses in Bangor and Holywood, brick terraces and post-war estates.
How much will subsidence repairs cost in Bangor?
Prices in Bangor are worked out on Northern Ireland rates. They include VAT and are a starting point: access, the extent of the damage and whether an engineer or building control is involved all move the figure.
| Item | Guide price | Per |
|---|---|---|
| Structural engineer's investigation and report | £440 – £1,750 | per property |
| CCTV drain survey (common first check) | £130 – £310 | per survey |
| Typical repair once the cause is dealt with: crack stitching and making goodest. | £2,200 – £10,600 | per property |
| Foundation strengthening where it is needed (see underpinning) | £880 – £3,100 | per metre of wall |
Which repair method suits a home in Bangor?
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
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
What happens when we carry out subsidence repairs in Bangor?
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.
Signs you may need subsidence repairs
- Diagonal cracks wider at the top, running from window or door corners
- Cracks that open in summer and partly close again in winter
- Doors and windows that start to stick or no longer close
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.
Subsidence repairs in Bangor: questions and answers
How much should I budget for subsidence repairs in Bangor?
Guide prices for subsidence repairs in Bangor 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 Bangor?
We do. Bangor and the surrounding area are covered, including nearby Newtownards 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.
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.
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.
