Patios take years of rain, frost, foot traffic and garden furniture. These are the signs that the joints or slabs need work
Mortar that has cracked, shrunk away from the slabs or washed out entirely. Once the joints are open, water gets under the slabs and the problem speeds up.
Weeds only take hold where the joints are open or soft. Pulling them out won't fix it for long; the joints need refilling.
Slabs that move underfoot usually have a failed bed underneath, not just failed joints. They're a trip hazard and need lifting and relaying.
Single cracked slabs can often be lifted out and replaced. We can source matching slabs where possible.
Dips where puddles form, or water running towards the house, mean the base or the fall has failed. That needs relaying to the right fall, not just repointing.
Algae, moss and dirt build up on shaded patios. Cleaning is usually the first step before repointing.
“…The loose slabs were fixed perfectly, and the new pointing gives it such a clean, professional look!”
| If you see… | Usually the fix is… |
|---|---|
| Open, crumbling or weedy joints, but the slabs are firm | Repointing: old jointing raked out and the joints refilled |
| A few loose, cracked or sunken slabs | Slab repairs: those slabs lifted, rebedded or replaced, then the joints repointed |
| Many loose slabs, widespread dips or water running the wrong way | Relaying the affected area on a new bed, to the right fall |
We’ll check the slabs and the bed when we visit and tell you which it is. For paths and driveways, see our slab repairs for paths and driveways.
We provide a wide range of patio repair and repointing services, tailored to different property types
Old and failed jointing raked out, joints cleaned, and refilled with a jointing material suited to your slabs.
Loose or sunken slabs lifted, the bed made good, and the slabs relaid level with the rest of the patio.
Dirt, moss and algae cleaned off so the new joints bond and the finished patio looks even. For brick walls and house fronts, see brick cleaning .
Loose treads, open joints and crumbling mortar on garden steps repaired and repointed.
If your patio is edged by brick walls or raised beds, we can repair and repoint those at the same time. See garden walls repaired and repointed.

such as sandstone (including Indian sandstone), limestone, slate and York stone.
It's non-porous and stains easily, so it needs the right jointing material and a careful, clean method.
including older riven and smooth flags.
Telling us the type of stone helps us quote accurately. If you’re not sure what you have, a photo is enough.
The joint filler matters as much as the work itself. The right one depends on the slab type, the joint width, and how much use and water the patio gets. We’ll recommend the option that suits your patio and explain why. Whatever the filler, the joints have to be raked out to a good depth and cleaned first, or the new jointing won’t last.
The standard option for many natural stone and concrete patios. Strong and long-lasting when the joints are packed properly, but it needs dry weather to cure and can stain slabs if it isn't cleaned off carefully.
A wetter mix worked into the joints across the surface. It's quick and fills joints completely, but it needs careful cleaning off, especially on porous stone.
Resin or polymer-based compounds brushed into the joints. They're popular on porcelain and where a neat, even finish matters, and some types can be laid in damp weather.
Our step-by-step approach ensures durable and visually appealing patios
We check the joints, how firm the slabs are, the bed underneath, the drainage and the slab type, then give you a written quote.
The patio is cleaned, and old and loose jointing is raked out to a consistent depth.
Loose, sunken or broken slabs are lifted, rebedded or replaced, level with the surrounding patio and to the right fall.
Joints are filled and finished with the agreed jointing material, packed firmly and tooled neatly.
Residue is cleaned off the slabs, and we tell you when the patio can be walked on and used again.

It depends on the jointing used, how much water and traffic the patio gets, and how well it was laid. Well-laid joints can last many years, but shaded, wet patios and those with weak or shallow joints fail sooner. Weeds and open joints are the sign it's time.
Yes, if the slabs are firm. We rake out the old joints and refill them. Loose or sunken slabs have to be lifted and rebedded first, or the new joints will crack again.
Properly filled joints leave weeds very little to grow in, so it makes a big difference. Some moss and seeds can still settle on the surface, especially in shade, and these are easy to brush off.
Porcelain is non-porous and stains easily, so it needs a jointing material and method suited to it, often a brush-in compound or a specialist mix. We'll recommend one when we see your patio.Â
Usually, yes. We cut it out, prepare the bed and lay a replacement. Matching the colour exactly can be hard with older or weathered slabs, so we'll talk you through the options.
With sand and cement joints, light foot traffic after about 24 hours, and furniture after a few days. Brush-in compounds vary, and we'll tell you for your patio.
