Locate the cause before any repair work starts

Ground movement beneath a bay window usually has a clear and fixable cause, often something far less involved than underpinning. Cracking around a bay often traces back to a leaking drain, clay soil shrinking in dry weather, or a tree pulling moisture from below the foundations. A local specialist works out exactly what is happening below the structure and recommends work proportionate to what the evidence shows.

How it works

Our bay window subsidence repair services

Proper bay window subsidence repair work runs in a set order: investigate to find what is actually causing the movement, monitor where more time is needed to get a clear picture, then carry out the right remedy, which may be a drain repair, tree management, resin injection or, where the foundations genuinely need it, underpinning.

Your first message through to finished repair

  1. 1

    Tell us what you are seeing

    Use the contact form to give the address and a brief account of the symptoms. Note which walls are affected, the direction any cracking runs, and roughly how wide the gaps look. If the bay window floor has tilted or the roof line has shifted, say so. Say when the trouble first appeared and whether it has grown since. A picture taken beside a pen or ruler puts the scale in context. Your quote is free.

  2. 2

    A specialist calls you back

    A bay window subsidence specialist will telephone you to go over the details and put further questions to you. They will ask about the age of the bay and the main structure, the ground conditions beneath the footings if you have any knowledge of them, whether tree roots are active nearby, and whether a gutter or underground pipe has been losing water close to the base. Let the specialist know at this stage if an insurer has opened a file.

  3. 3

    Establishing whether an inspection is required

    From your account, the specialist decides whether attending the site will add material information. Where movement appears to be continuing, crack monitors can be fitted to record data over a number of weeks. The pattern of readings reveals whether the bay is still shifting, whether clay shrinkage is the main driver, or whether the structure has reached equilibrium. That evidence determines which repair method is appropriate.

  • Cracks that are wider at one end, suggesting tilt or rotation of the bay
  • Bay window frames that have fallen out of square or started to stick
  • Cracks visible on the interior and exterior face of the same wall
  • Cracks that open up or grow wider following a long dry period, especially where large trees stand nearby
  • Steps or a bay floor that have tilted or pulled apart from the main building

What drives subsidence in the United Kingdom?

Soil types and ground conditions across the United Kingdom mean the reasons behind bay window movement vary from property to property. Specialists most commonly identify the following causes:

  • Clay soils shrinking as moisture is drawn out, often by nearby trees
  • Broken or leaking drains saturating the ground around the foundations
  • Tree roots drawing moisture out of clay soil beneath the building
  • Poorly compacted fill or made ground settling under load
