Subsidence repairs in Sunderland
Cracks in a house in Sunderland 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.

What is the ground like in Tyne and Wear?
With roughly 170,000 people, Sunderland spans postcode districts SR1, SR2, SR9 in Tyne and Wear. We also take enquiries from nearby Seaham (5 miles), Washington (5 miles) and Houghton-le-Spring (6 miles).
Parts of Tyne and Wear have clay that can shrink near trees in dry spells. Historic coal workings are recorded beneath parts of Tyne and Wear, and a coal mining search is worth checking where movement is unexplained. Across Tyne and Wear, most homes are Tyneside flats and terraces, Victorian villas, inter-war council estates and post-war semis.
What happens when we carry out subsidence repairs in Sunderland?
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
- Diagonal cracks wider at the top, running from window or door corners
- A gap opening between the skirting board and the floor
- Fresh cracks showing on both the inside and outside of one wall

Which repair method suits a home in Sunderland?
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 England
In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.
Subsidence repairs in Sunderland: questions and answers
How much will subsidence repairs cost in Sunderland?
Guide prices for subsidence repairs in Sunderland start from about £2,300 per property, including VAT, on North East rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Sunderland?
Yes, Sunderland is covered, along with postcode districts SR1, SR2, SR9. We also cover nearby Seaham and Washington.
Is the ground in Tyne and Wear prone to subsidence?
Tyne and Wear lies on the Durham and Northumberland coalfield, with old shallow workings recorded beneath parts of Newcastle, Gateshead and Sunderland, mostly under a cover of glacial clay. Only an investigation can say why a particular building has moved.
How long should I wait before repairing subsidence cracks?
Usually until the cause has been dealt with and the engineer is satisfied that movement has stopped. On clay that can mean watching the house through a summer and a winter. Repairing too early risks the same cracks opening again.
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.
