Subsidence Help
Find out what the movement means for your home and what the options are before any work begins.
Repair Methods
A sticking door or a new crack can mean several things. The specialist surveys the home, finds the cause and sets out what needs doing.
Resin Injection
Stabilise sinking ground beneath footings without digging up the garden or leaving the house.
Concrete Cracking
Find out why a concrete floor slab cracks and how a specialist repairs it without replacing it all.
Screw Piling
Support a home where the foundations cannot hold, using steel piles driven into stable ground.
Underpinning
Strengthen failing foundations on older homes so the walls stop moving each time the clay dries out.
Leaning Bay Windows
Read why bay windows lean away from the main wall and what stabilises them again.
What Happens?
Barnet Subsidence takes enquiries from homeowners who have noticed something wrong. You describe what you see, and one specialist firm covering your part of the borough reads it. That firm contacts you directly to arrange a survey. The specialists carry out all inspections and structural work under their own contracts and insurance.
About Us
Tell us what you have noticed in your home. One specialist covering your area will read it and get in touch.
The specialist surveys the building, identifies why it is moving and recommends only the repair that addresses that cause.
Cause Guides
Homes in Barnet move for different reasons depending on the soil, the trees and the age of the building.

Why Crack Monitoring Comes Before Repairs
A common pattern: a specialist fits gauges across a crack and waits for readings over several months before specifying any work.
When Resin Injection Replaces Underpinning
Where ground conditions allow, resin stabilises shallow foundations without excavation work.
Subsidence help
A claim needs evidence of the cause, not just the damage. Missing soil data or tree surveys stalls it.
Common Questions
Diagonal cracks wider than a few millimetres, doors that stick in frames they used to clear, and gaps opening between skirting boards and walls are typical signs. Hairline cracks in new plaster are usually shrinkage. A specialist survey determines which one you are looking at.
London Clay shrinks when it dries, and mature trees draw moisture from it during long summers. Leaking drains wash fine material out from under footings. Older parts of the borough sit on infilled ground that still settles. The cause dictates the repair.
Most policies cover subsidence subject to an excess. The specialist firm supplies the structural report and deals with the insurer directly, so the homeowner does not have to argue the technical case alone.
Resin injection on a single bay can be done while the household stays in place. Traditional underpinning along a full wall takes longer because each section must cure before the next is dug. The specialist sets out the timeline after the survey.
Usually no. Most repairs happen while people live in the home. Where work affects a kitchen or bathroom, the specialist plans the sequence so those rooms remain usable throughout.
