Those gaps between your patio slabs aren't just unsightly – they're letting water seep beneath, causing movement and damage. Norbury's clay soil makes proper repointing essential for keeping patios level and secure through our wet winters.

Victorian terraces throughout SW16 often feature original stone patios that have weathered over a century. When mortar joints crumble, weeds take hold and slabs shift underfoot. Professional repointing breathes new life into these heritage features while protecting the substrate from London's freeze-thaw cycles.
Modern polymeric compounds bond far stronger than traditional sand-cement mixes. Applied correctly to clean, dry joints, these flexible mortars accommodate natural stone movement whilst repelling water penetration. The result? Weed-free gaps that stay sealed despite Norbury's notorious soil shrinkage during summer droughts.
Twenty years working on properties from Pollards Hill to Thornton Heath means understanding which pointing methods suit different stone types. Whether it's York stone on Edwardian villas or modern porcelain near Streatham Common, matching the right compound to your patio ensures lasting results.

Standard patios around 20-30m² typically range £600-£900, though intricate patterns or delicate natural stone may increase costs. Larger Victorian properties with 50m² courtyards usually fall between £1,200-£1,800 depending on joint width and stone condition.
Absolutely – from the Conservation Area near Norbury station through to properties backing onto Norbury Park, including all residential streets between Streatham and Thornton Heath. Regular projects span both postcodes weekly.
Most residential patios require 2-3 days total: joint clearing and preparation on day one, compound application when conditions are dry, then 24-hour curing before light foot traffic resumes.
Every completed patio carries decade-long coverage against joint failure, compound degradation or water ingress. This comprehensive guarantee reflects the premium materials used and proven installation techniques developed specifically for South London conditions.
Repointing stabilises existing layouts but won't level displaced slabs. Minor rocking often improves once joints are sealed, preventing further water damage. Significant movement requires lifting and re-bedding affected areas before new pointing – something we'll assess during quotation.
