Subsidence repairs in Essex
We carry out subsidence repairs across Essex, from the larger towns to smaller places nearby. Much of Essex sits on clay that shrinks in dry summers and swells in wet winters. Every job starts with the cause, then the repair is specified to match it.

Why does the ground in Essex matter for subsidence repairs?
London Clay covers much of south and central Essex and boulder clay much of the north, making it one of the counties most affected by clay shrinkage in dry summers. Street and garden trees close to houses add to the risk.
Ground movement here is more often linked to soils, drains and trees than to mining. Across Essex, most homes are Victorian terraces, 1930s semis and bungalows, and large post-war new-town estates in Basildon and Harlow.
What should you budget for subsidence repairs in Essex?
These are guide prices for Essex, using East of England rates and including VAT. Your written quote follows photos or a survey, and is fixed once the repair is specified.
| Item | Guide price | Per |
|---|---|---|
| Structural engineer's investigation and report | £525 – £2,100 | per property |
| CCTV drain survey (common first check) | £160 – £370 | per survey |
| Typical repair once the cause is dealt with: crack stitching and making goodest. | £2,600 – £12,600 | per property |
| Foundation strengthening where it is needed (see underpinning) | £1,050 – £3,700 | per metre of wall |
Repair options we may recommend
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
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 to expect when we carry out subsidence repairs
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.
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.
Is it time for subsidence repairs? Common signs
- Diagonal cracks wider at the top, running from window or door corners
- Wallpaper rippling or tearing where the wall meets the ceiling
- A gap opening between the skirting board and the floor
- Fresh cracks showing on both the inside and outside of one wall
Do you need approval 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.

Your subsidence repairs questions
Does the ground around Southend-on-Sea cause cracking?
London Clay covers much of south and central Essex and boulder clay much of the north, making it one of the counties most affected by clay shrinkage in dry summers. Street and garden trees close to houses add to the risk. Ground movement here is more often linked to soils, drains and trees than to mining. Only an investigation on site can say why a particular building has moved.
How much will subsidence repairs cost in Essex?
On East of England rates, subsidence repairs starts from about £2,600 per property, including VAT. The written price depends on the extent of the damage, access and whether an engineer or building control is needed.
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.
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.
How do I know if cracks are subsidence?
Subsidence cracks are usually tapered, run diagonally from door and window corners, and show on both faces of the wall. Fine vertical cracks in new plaster are more often shrinkage. An engineer’s inspection, sometimes with monitoring, is the reliable way to tell.
