What Goes Wrong

Why a clean alone does not hold

The most common failure is treating each problem separately, or only treating the surface.

Cleaning Over Open Joints

Pressure washing a patio with washed-out joints clears the surface but leaves the gaps open, weeds re-establish within one growing season.

Joint Depth Check First

Joint depth is measured after washing; anything below 20mm is raked out and repointed before the visit ends.

Repointing on Moving Slabs

Fresh mortar applied over a rocking slab cracks within weeks because the movement beneath breaks the new joint before it cures.

Slab Stability Before Pointing

Loose slabs are lifted and re-bedded on fresh mortar first, so the new joints have a stable base to bond to.

Wrong Jointing Material

Using standard mortar in a wide sand joint, or re-sanding a mortar-jointed patio, leads to rapid washout and the same problem returning after the first wet winter.

Material Matched to Joint

Mortar, polymeric compound or jointing sand is chosen by joint width and slab type, not applied as a single default across the whole patio.

Drainage Not Assessed

Water pooling in joints accelerates mortar washout and algae regrowth; cleaning and repointing without checking the surface fall means the cycle repeats.

Fall Check at Repoint Stage

The drainage fall across the surface is checked during repointing; if water sits in joints rather than running off, the issue is flagged clearly.

Scope of Work

What the combined service covers

Each stage is assessed on arrival, not every patio needs all three, but all three are checked on every visit.

Joint Depth Check

Measured after washing to confirm repointing is needed.

Surface Drainage Assessment

Fall across the patio checked at the repointing stage.

Hollow Slab Report

Hollow but stable slabs noted for the homeowner to monitor.

Clean, Point, Fix

Patio cleaning, repointing and repair, three stages, one visit

Weeds and loose slabs come back after a clean because the joints and bedding were not addressed at the same time.

Request a Survey

The visit starts with a surface assessment. Algae and moss are pressure washed from the slab faces and joints. Peterborough’s wet winters accelerate algae growth and mortar washout, so older patios often need both cleaning and repointing in the same session. Joint depth is checked after washing, if the mortar or jointing sand has washed out below 20mm, weeds will re-establish within a growing season regardless of how clean the surface looks.

Repointing follows once the surface has dried sufficiently. Crumbling or missing mortar is raked out and replaced with fresh mortar or a polymeric jointing compound depending on the joint width and slab type. Sand-jointed paving is re-sanded and compacted. The drainage fall across the surface is checked at this stage, if water is sitting in joints rather than running off, the fall may need correcting as a separate job.

Loose slab repair is the final stage. Slabs that rock or have dropped are lifted, the bedding beneath is assessed, and the slab is re-bedded on fresh mortar. A hollow-sounding slab that is not yet loose is noted on the report so the homeowner can decide whether to address it now or monitor it. Most patios can be restored through this three-stage process without any full replacement.

Common Questions

Questions about patio cleaning, repointing & repair

  • Do I need repointing if the patio has just gone dirty?

    Not necessarily. If the joints are solid and intact, cleaning alone is enough. Repointing becomes necessary when joints are crumbling, hollow, or missing, conditions that let water and roots get underneath the slabs. Check the joints by pressing them; if they crumble or flex, repointing is needed alongside the clean.

  • How do I know if my patio needs repair as well as cleaning?

    Walk across the patio and press each slab with your foot. Any rocking, hollow sound underfoot, or visible cracking in the slab itself points to repair work beyond cleaning. Crumbling joints alone usually mean repointing; a slab that moves or has broken edges needs lifting and re-bedding.

  • Will pressure washing damage my patio?

    Pressure washing at the wrong PSI or angle can erode soft mortar joints and pit porous stone. The risk is highest on older sand-set joints and softer materials like sandstone. Using the correct pressure and a fan nozzle rather than a pencil jet keeps the surface safe.

  • Can I pressure wash my patio myself without making the joints worse?

    You can, but the risk is real. Consumer pressure washers often lack pressure control, and directing the jet along a joint rather than across it strips mortar quickly. If your joints are already thin or crumbling, DIY pressure washing will accelerate the damage and bring forward the cost of repointing.

  • Is patio cleaner enough instead of repointing?

    Chemical patio cleaner removes algae and staining from the surface but does nothing to failed mortar joints. If joints are open or crumbling, water continues to get underneath the slabs regardless of how clean the surface looks. Cleaning and repointing address different problems and often need to be done together.

  • Will cleaning alone stop weeds coming back?

    Cleaning removes existing weeds and seeds, but it does not seal the joints against regrowth. Weeds return through open or crumbling mortar gaps. Repointing with a polymeric or brush-in jointing compound after cleaning is the most effective way to reduce regrowth long-term.

  • Why are the slabs coming loose or wobbling?

    Loose slabs are almost always caused by a failed mortar bed underneath. Water gets in through cracked joints, erodes the bedding layer, and leaves the slab unsupported. Clay-heavy ground that swells and shrinks with moisture also undermines the bed over time, particularly after wet winters.

  • Can a patio be repaired without replacing the whole area?

    Yes. Individual slabs can be lifted, the bed re-laid, and the slab reset without disturbing the rest of the patio. Partial repair works well when damage is isolated. If subsidence or drainage failure is widespread, a larger area may need attention to prevent the same slabs moving again.
