Can a sunken patio be fixed without replacing the whole thing?

Yes, in most cases. Contractors lift only the affected slabs, rebuild the base underneath, and relay them. Full replacement is only needed if the sub-base has failed across most of the area.

Why has my patio started sinking after several years?

Usually it's water getting under the slabs and washing out the bedding or sub-base, tree root growth, or the ground settling unevenly. Older patios laid on a thin sand bed are more prone to this.

Is a sunken patio urgent?

It's not usually an emergency, but if it's sloping towards your house or a doorway it's worth getting looked at soon, since it can push water where you don't want it.

Sunken or uneven patio repair in Cheltenham

Patios sink or go uneven when the base underneath washes out, settles unevenly, or was never properly compacted in the first place. You'll notice slabs that rock underfoot, pools of standing water after rain, or a dip forming near a doorway or drain. This is a repair job, not a full patio replacement: a contractor lifts the affected slabs, rebuilds the sub-base or bedding layer, and relays the same slabs so they sit flush again.

Common causes: poor original sub-base, tree root movement, water pooling under the slabs, frost heave over winter
What a fix involves: lifting slabs, checking and rebuilding the base, adjusting levels, relaying and repointing
Worth flagging early: a sunken patio near the house can direct water towards your walls or foundations

Contractors who do driveway and patio work in Cheltenham will usually also handle this kind of localised repair without needing to relay the whole area.

What it costs

Cost depends on how many slabs need lifting and whether the sub-base has failed across a small patch or the whole patio. A localised dip involving a handful of slabs is a much smaller job than one where the entire base has washed out and needs rebuilding. Get a contractor to inspect in person, since photos rarely show how deep the problem goes.
