Patio repairs in the UK typically cost between £150 and £600. It's the cheapest job on this site, and for most homeowners it's also the one with the best return — a rocking slab by the back door or a cracked flag under the table is a trip hazard and an eyesore, and neither needs anything like a full patio replacement to put right.
Patio repair cost by job size
These are typical prices for patio repairs, covering lifting, re-bedding or replacing the affected slabs and repointing around them.
Typical UK prices. Actual quotes vary by the cause of the damage, whether matching paving is available and how far the contractor is travelling.
| Job size | What's usually involved | Typical cost |
|---|---|---|
| Single slab repair | One slab lifted, the bedding beneath topped up and re-compacted, the slab reset level and repointed | £150 – £300 |
| A few slabs or a small area | Several adjacent slabs lifted and re-bedded, or one or two replaced with matching paving | £300 – £450 |
| Larger repair, multiple areas | Work in more than one part of the patio, or repairs where the sub-base has to be rebuilt locally | £450 – £600+ |
The minimum call-out charge changes the maths
Look at that table again and you'll see something odd: fixing four slabs doesn't cost four times what fixing one does. That's because most of a small repair is the visit, not the work. Travel, setting up, mixing a bed, and coming back to check it has cured all happen once, whether the contractor lifts one slab or six.
The practical consequence is worth acting on. If you have one wobbling slab now and two more you've been meaning to sort out, get them all done in the same visit. Calling someone back out in six months for the next one means paying the fixed part of the bill twice. It's the single easiest way to get more for your money on the lowest-value job this trade does.
Matching the existing slab is the real variable
Re-bedding a slab that's still in one piece is straightforward. Replacing a broken one depends entirely on whether a match can be found, and this is where a simple-sounding repair occasionally turns awkward.
- Paving ranges are discontinued regularly. A patio laid fifteen years ago may be in a slab that's no longer made in that size, colour or texture.
- Even where the range still exists, a new slab comes out of the pack looking new. Fifteen years of British weather changes the tone of natural stone and the surface of concrete, so a perfect product match can still look obvious for the first couple of years. It does usually blend in with time.
- Where no match is available, the practical options are lifting a slab from a hidden spot — under a bench, behind a shed, at the far edge — and using the new one there instead, or accepting a deliberate contrast rather than a failed match.
If you have spare slabs left over from the original installation sitting behind the shed, this is what they're for. It's worth checking before you call anyone.
What changes a repair quote
- How many slabs are affected, and whether they're together or scattered across the patio.
- Whether the slab can be re-bedded or has to be replaced, and whether a match is available.
- What caused the damage. A slab that sank because the bedding washed out needs the cause dealt with, not just the symptom — if water is the reason, patio drainage may be the real fix, and the patio drainage cost guide covers what that runs to.
- Access. Getting a replacement slab and a bag of bedding material to a back garden with no side access takes longer than to a front one.
- Whether the joints around the repair need making good — they usually do, and on an older patio that can shade into a wider repointing job.
One sunken slab is a repair. The same slab sinking again a year later means the bedding is being washed out from underneath, and re-bedding it a second time will buy the same year. Where a patio has more than one slab going the same way in the same area, it's worth having the drainage and the falls looked at before spending anything on the paving.
When a repair stops being worth it
Repairs pay off when most of the existing surface is still in good condition. Once damage has spread across the majority of the patio, you end up paying repeatedly for the same visit and still looking at a tired surface — at that point a full patio installation is usually the better value. Our guide on whether to repair, repoint or replace your patio sets out where that line falls, the signs your patio needs work checklist covers what to look for, and the patio cost calculator gives you a rough figure for either route.
Frequently asked questions
How much does patio repair cost on average?
Most UK patio repairs cost between £150 and £600, depending on how many slabs are affected and whether matching replacement paving is needed. A single slab typically sits at the lower end, and because much of the cost is the visit itself, several slabs done together usually work out better value per slab.
Can a cracked patio slab be repaired instead of replaced?
Sometimes. A hairline crack in a slab that's still firmly bedded and not rocking can often be left or filled, particularly if it's out of the main walking route. A slab cracked right through, or one that moves underfoot, is generally lifted and replaced — a cracked slab that moves will work the joints around it loose as well.
Why has my patio slab sunk?
Nearly always because the bedding underneath has been washed out or was never properly compacted. Water running under the slab carries fine material away and leaves a void, and the slab drops into it. That's why a sunken slab often appears near a downpipe, at the low point of the patio, or wherever water sits after rain.
How long does a patio repair take?
Usually a day or less for a straightforward repair. The work itself is quick; what takes the time is sourcing matching paving if a slab needs replacing. Fresh pointing around the repair will need a few days to cure before the area gets normal use.
