Mining subsidence repairs in Canterbury

Population: about 55,000
Area: Kent
Pricing region: South East

Is Kent prone to ground movement?

Postcode districts CT1, CT2, CT5, CT6 cover Canterbury, a Kent town of about 55,000 people. If you are just outside Canterbury, we also cover Whitstable (6 miles), Herne Bay (7 miles) and Faversham (9 miles).

Much of Kent sits on clay that shrinks in dry summers and swells in wet winters. Parts of Kent lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across Kent: Victorian terraces in the Medway towns, weatherboarded and Wealden houses, 1930s semis and seaside bungalows.

Methods for mining subsidence repairs

Pricing an engineer’s repair scope

When a claim is under way, the engineer or claim handler usually writes the scope of repairs. We price that schedule item by item, at no charge to request, and carry out the work if you choose us. Anything outside the scope is shown separately.

Best for: Homeowners with a mining claim or engineer’s report in hand

Crack stitching and making good

Where the ground has stopped moving and the damage is cracking, the walls are stitched with stainless helical bars, repointed and replastered. This covers a large share of mining damage, especially legacy movement that settled years ago and left cracks behind.

Best for: Cracking after movement that has now stopped

From first photo to finished repair

Check the mining record
A coal mining report or a search of mining records shows whether recorded workings or shafts lie near the property. Records are incomplete, so a clear report does not rule mining out, and a recorded seam nearby does not prove it is the cause.
Engineer’s assessment
An independent chartered structural engineer inspects the damage and, if needed, recommends drilling or ground investigation to locate voids. We can arrange the engineer. Their report sets out the cause, whether movement has stopped and what repair is needed.
Written price to the scope
We price the repair from the engineer’s or claim schedule and confirm a fixed price in writing once the work is specified. Where a claim body or insurer is handling the repair, their own process for appointing contractors applies.

Rules for mining 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.

Frequently asked questions

How much should I budget for mining subsidence repairs in Canterbury?

Guide prices for mining subsidence repairs in Canterbury start from about £90 per metre of crack, including VAT, on South East 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 Canterbury?

Yes. We take enquiries from across Canterbury, including CT1, CT2, CT5, CT6, and from nearby places such as Whitstable and Herne Bay. Send photos for a free initial view and we will tell you what happens next.

Why do houses in Kent crack?

North Kent sits on London Clay, central Kent on Gault and Weald Clays and the Downs on chalk, so shrinkable clay is widespread. East Kent around Deal and Dover had a small deep coalfield, worked until the late 1980s. Only an investigation can say why a particular building has moved.

Can you repair mining damage that is not part of a claim?

Yes. If the damage is old and settled, or a claim has been closed, we can repair it privately. Send photos for a free initial assessment and you will receive a no-obligation written quote. If the cause is unclear, an engineer’s inspection first is sensible.

Is my house affected by mining because it is on a coalfield?

Not necessarily. Many homes on coalfields have no mining-related damage at all, and cracks there can still come from clay, trees or drains. A coal mining report shows recorded workings nearby, and an engineer’s inspection is needed to link damage to mining.
