Could it be subsidence?
Ground movement leaves recognisable marks on a building. Every sign listed below is worth having a specialist look at, even if the cause turns out to be straightforward.
Diagonal cracks more than 3mm wide that run from the corners of door or window openings
Cracks that are wider at one end than the other, suggesting rotation or tilt
A visible gap opening between a porch and the main house wall
Doors or windows that have recently started sticking or dropped out of alignment
Cracks that appear on both the inner and outer face of the same wall
Cracking that appears or widens after a prolonged dry spell, particularly near large trees
Steps or a porch floor that have tilted or separated from the main structure
What causes subsidence in the United Kingdom?
Ground conditions vary across the United Kingdom and the triggers for movement differ from one property to the next. The causes most frequently identified by specialists include:
- Shrink-swell clay soils losing moisture during dry periods, particularly where tree roots are drawing water from the ground
- Cracked or leaking underground drains that soften or erode the soil around foundations
- Roots drawing moisture from clay beneath or immediately beside a porch foundation
- Made ground or poorly compacted fill continuing to settle beneath a structure over time
- Old shallow foundations on a porch that were never designed to cope with significant ground movement
Why Porch Subsidence
Find the cause before committing to any repair
Subsidence sounds alarming, yet the ground beneath most affected homes is doing something straightforward and fixable. Cracking that gets pinned on subsidence is regularly traced back to a leaking pipe, clay soil drying out, or a tree pulling moisture from beneath the foundations, none of which require underpinning to put right. A local specialist establishes exactly what is happening below your home and recommends only the work the findings actually justify.
