Our subsidence repair services

Effective subsidence repair work follows a logical order: investigate to establish the true cause, monitor where movement needs confirming, then apply the right remedy, which may be drainage repair, tree management, resin injection or, where genuinely needed, underpinning.

From your first call to completed repair

  1. 1

    Enter your details in the form

    Tell us the property address and what you have seen: where the cracks are, which way they run, roughly how wide, and when you first spotted them. If a wall is bowing, a floor has dipped at one corner, or a door frame has separated from the surrounding brickwork, mention that too. A photograph taken next to a pen or coin helps the specialist read the scale before they call. Your quote is free.

  2. 2

    A specialist calls you

    A subsidence specialist will phone you to go through what you have described and ask further questions. The specialist will want to know how old the property is, what soil sits beneath it if you know, whether large trees are growing close by, and whether a drain or gutter near the affected area has been leaking. Let the specialist know at this stage if an insurer has already opened a claim.

  3. 3

    Assessing whether a site visit is required

    Using the details you have provided, the specialist decides whether a visit to the property would give them information they cannot get any other way. If movement appears to be ongoing, monitors can be fitted to the cracks and left to log readings over several weeks. Those readings reveal whether the ground is continuing to move, whether clay shrinking in dry conditions is the cause, or whether the structure has settled into a stable state. That evidence determines which repair method fits.

The process

Is your home showing these signs?

Movement leaves clues. Any of the following is worth an inspection, even if it turns out to be nothing.

Signs worth getting a specialist to check

  • Diagonal cracks wider than a 10p coin (3mm), often near doors and windows
  • Cracks that taper, wider at the top than the bottom
  • Doors and windows that suddenly stick or drop out of square
  • Cracks visible both inside and outside in the same place
  • Rippling wallpaper or gaps opening where extensions meet the main house
  • Cracking that worsens after a hot, dry summer or near a large tree

What causes subsidence in Greater London?

Ground conditions vary across Greater London. Movement is often linked to shrink-swell soils, leaking drains or nearby trees. The most common local triggers are:

  • Clay shrinkage, often drawn out by nearby trees
  • Leaking drains washing out or softening the ground
  • Tree roots taking moisture from clay soils
  • Made ground and poorly compacted fill settling over time
