Cracks that open in summer and close in winter

Upminster sits on deep London Clay that shrinks when dry and swells when wet. Mature trees draw moisture from the ground beneath older footings, so walls move slightly with the seasons and plaster splits along the stress lines.

  1. 1

    Diagonal cracks near windows

    A crack wider at the top than the bottom, often near a window frame. This pattern can point to one side of the wall dropping lower than the other.

    Doors sticking in their frames

    A door that catches on the frame or will not latch properly. The opening may have shifted out of square because the wall around it has moved.

  3. 3

    Gaps between skirting and floor

    A visible space opening up where the skirting board meets the floorboards. The floor might be dropping away from the wall as the ground dries out.

    Plaster cracking at ceiling corners

    Fine lines spreading from the corner where two walls meet the ceiling. Repeated small movements tend to show themselves first at these junctions.

What happens below

Why Upminster clay moves under heavier houses

Detached and semi-detached interwar houses carry more weight across a wider footprint. When the clay beneath them dries unevenly, the foundations settle at different rates and the brickwork above cracks along the weakest mortar joints.

Large gardens with established oaks, willows and poplars pull significant moisture from the soil during summer. Roots can reach far beyond the canopy spread, drying the clay directly under shallow strip footings built decades ago.

Seasonal shrinkage produces a cycle: cracks widen through late summer and narrow again after winter rain. A specialist monitors this pattern over months before deciding whether the movement is ongoing or settling into a predictable range.

Older drainage runs laid in clay pipes can fracture as the ground shifts. Leaking water then softens the soil in one spot, adding another cause of movement that needs ruling out before any foundation work begins.

Foundation work carried out by specialist firms

Separate specialist firms handle each type of repair. They assess the ground conditions first and recommend only the method suited to the problem.

Subsidence investigation
A specialist surveys the property, records crack widths and checks drainage to establish whether the movement is active or historical before proposing any repair.
Underpinning
Where foundations need deeper support, a specialist excavates sections below the existing footing and pours new concrete to reach stable ground.
Resin injection
A specialist pumps expanding resin into voids beneath the slab or footing to fill gaps left by shrinking clay and lift settled sections back toward level.
Concrete repair
Cracked garage floors, drives and internal slabs are assessed by a specialist who cuts out damaged sections and replaces them with reinforced concrete.
Screw piling
For extensions or unstable ground, a specialist drives steel screw piles deep into load-bearing strata to provide a fixed base independent of surface clay.
