Short answer
Patio repointing in Chester typically costs from around £150 for a small repair area, from £250 for a full patio section, and from £95 to re-sand block paving. The final price depends on the patio size, how many joints have failed, and whether it needs cleaning before the new pointing or sand goes in.
Why Chester patios lose their joints
Repointing is replacing the mortar between paving slabs; re-sanding is brushing fresh kiln-dried sand back into block-paving joints. They sound similar but they are different jobs, and which one you need comes down to how your patio is laid.
Across Chester, Hoole, Handbridge and the wider Cheshire and Wirral area, our wet climate is hard on patio joints. Water sits in the joints through a long damp autumn, then freezes and expands over winter — that freeze-thaw cycle is what cracks mortar and pops it out in lumps. North-facing and shaded patios stay wet longest, so they tend to fail first.
Once a joint goes, the problem speeds up. Open gaps let more water under the slabs, weeds and moss root in the cracks, and slabs start to rock. On older Cheshire properties with sandstone or Indian stone patios, sound joints are what hold the whole surface stable — which is why repointing early is far cheaper than relaying a patio that has started to lift.
Patio repointing & re-sanding — guide prices in Chester & Cheshire
| Job | Guide price | What affects it |
|---|---|---|
| Small repair area — failed joints made good | From £150 | A handful of cracked or missing joints in one area |
| Full patio section — repointed | From £250 | A whole patio or large section with widespread joint failure |
| Block paving re-sand (kiln-dried sand) | From £95 | Brushing fresh sand into block-paving joints to lock the blocks |
| Clean before repointing | From £125 | Often needed first so new pointing or sand bonds to a clean joint |
| Loose or rocking slab re-bedded | From £45 | Per slab, where a slab has lifted and needs re-setting |
These figures are a guide for typical Chester patios. The job is confirmed after a few photos or a quick visit, because the patio type, the number of failed joints, and whether a clean is needed first all change the scope.
What a professional repointing job involves
- 1
Assess the joints and the slabs
We check which joints have actually failed, whether any slabs are loose or rocking, and whether the patio needs cleaning first so the new pointing has something clean to grip.
- 2
Rake out and prepare the joints
Old, crumbling mortar is raked out and the joints cleared down to a sound base. Skipping this is the main reason a cheap repointing job lifts again within a season.
- 3
Repoint or re-sand correctly
Slabbed patios are pointed with the right mortar mix, worked in and finished neatly. Block paving is re-sanded with kiln-dried sand brushed fully into every joint to lock the blocks and slow weed regrowth.
- 4
Finish, protect and tidy
We strike the joints to a clean finish, keep fresh mortar off the slab faces, and leave the patio swept. We will also let you know if a joint needs to stay off it while it cures.
Don't repoint over loose slabs or a failing base
Repointing only works when the slabs underneath are stable. If the patio is rocking, slabs have sunk, or the base has washed out, new pointing will simply crack out again within months and you will have paid twice. When several slabs move or the surface has dropped, the patio needs re-bedding or relaying — not just fresh joints — so get it looked at before spending money on pointing that won't hold.
Repointing vs re-sanding — which does your patio need?
| Repointing (mortar joints) | Re-sanding (block paving) | |
|---|---|---|
| Patio type | Slabbed patios — sandstone, Indian stone, concrete flags | Block paving and brick paviours laid on sand |
| What's gone wrong | Mortar cracked, crumbled or fallen out of the joints | Joints washed out, blocks loosening, weeds taking hold |
| What's used | A pointing mortar mix worked into the joint | Kiln-dried sand brushed into the joints |
| How long it lasts | Years when raked out and pointed properly | A few seasons — easy and cheap to top up again |
| Typical cost | From £150 for a repair, from £250 for a full section | From £95 for a re-sand |

Frequently asked questions
What's the difference between repointing and re-sanding?
Repointing replaces the mortar between slabbed paving. Re-sanding brushes kiln-dried sand back into block-paving joints. Slabbed patios get repointed; block paving gets re-sanded. We will tell you which yours needs once we see it.
Does my patio need cleaning before it's repointed?
Often yes. New mortar and fresh sand bond far better to a clean joint, so a heavily mossed or algae-covered patio is usually cleaned first. We price the clean separately so you can see exactly what you are paying for.
How long does fresh pointing take to cure?
New mortar needs time to set before heavy use, and it cures best when it is not soaked straight away. We will tell you how long to keep furniture and foot traffic off it, which depends on the weather at the time.
Will repointing stop weeds growing in my patio?
It helps a lot. Open joints are exactly where weeds and moss take root, so closing them with sound mortar or fresh sand removes the gap they grow in. It is not a permanent weedkiller, but it makes regrowth much slower.
Can you repoint and re-sand on the same visit as a patio clean?
Usually yes. Restoration work often follows straight on from a clean, because the surface is already prepped. Doing both together saves a return visit and gives a finished result in one go.
