Garden step and threshold re-levelling in the United Kingdom
Sunken garden steps and door thresholds, and the gaps that open beside them.
About garden step and threshold re-levelling
What this work involves
Garden steps and door thresholds are small, but a gap or tilt there is where people fall. A step settles when soil under it moves, or a threshold slab drops away from the door frame and lets rain and cold in.
The specialist looks at how the step has moved, whether it has pulled from the wall or door, and advises on lifting it with injection or on rebuilding it if the concrete itself is broken. Tell us where the step is and how big the gap has become, and the price is set for that job.

Does this describe your concrete?
- A gap has opened between the step and the door threshold.
- The top step has tilted away from the house and rainwater runs toward the door.
- Riser heights are now uneven, so one step feels bigger than the rest.
- The threshold slab sits lower than the door sill.
- Cracks have opened between the step and the wall, and the handrail is loose.
How the job gets done
Step inspection
The specialist looks at each step and threshold and measures how far they have dropped or pulled from the wall.
Gap finding
Small test holes show whether there is a void under the step or whether it is resting on soft ground.
Step lift
Resin is injected beneath the step in small steps until it is level with the door sill and the treads.
Threshold test
The step height at the door is measured again to check for a trip edge, and any gap is sealed.

Gaps at the door and tilting treads
Steps pulling away
Garden steps and door thresholds can drop or tilt when the ground beneath them shifts. A gap between the step and the house wall is the usual sign.
Frost and drainage
Water collecting behind or under a step freezes and heaves the ground. The specialist checks the drainage and how the step meets the wall.
Lifted as a unit
A single concrete step or threshold can often be lifted by injection and brought back to level with the door sill. Steps that have cracked through are described in the findings.

Unsure which fix applies? Browse the services
Can a garden step be lifted rather than rebuilt?
If the concrete is still in one piece and has simply dropped, injection can lift it back level with the door sill. Steps that have cracked through or broken apart are better rebuilt, and the specialist says which applies after looking at the step.
What causes a garden step or threshold to sink?
Soil under the step washes out through gaps at the sides or base, or was never firmly compacted when the step was built. Water from a downpipe or gutter discharging near the step is a common contributing factor.
How long does the repair take?
Most single steps or door thresholds are treated in an hour or two. A flight of three or four steps typically takes half a day. The specialist confirms the time once the number and condition of the steps are known.
Will the gap between the step and the house wall close up after lifting?
Lifting brings the step back to its original position, which usually closes most of the gap. Any remaining gap is pointed or sealed once the resin has cured and the step has stopped moving.
