Those widening gaps between your patio stones aren't just unsightly – they're letting water seep where it shouldn't. Streatham's clay soil shifts enough without help from failing mortar joints.

Victorian terraces throughout Streatham Hill often feature original York stone patios that have served families for generations. When pointing deteriorates, these beautiful surfaces become trip hazards and water traps. Modern repointing techniques preserve the character whilst solving drainage issues that plague properties between Tooting Bec Common and Streatham Common.
Fresh pointing transforms more than appearances. Properly sealed joints redirect rainwater away from foundations, crucial for homes on Streatham's notoriously expansive London clay. The process involves raking out crumbling mortar to a depth of 20-25mm, then applying weather-resistant compounds that flex with seasonal ground movement. This prevents the freeze-thaw damage that turns hairline cracks into costly repairs.
Local knowledge matters when dealing with Streatham's mix of sandstone, limestone and reclaimed materials. Having worked on properties from Furzedown's 1930s semis to converted mansions near Streatham Common station, understanding which pointing mix suits each stone type ensures longevity.

Medium-sized patios (30-40m²) typically range from £800-£1,400 in Streatham, depending on stone type and joint width. Larger Victorian terraces with 60m² patios might see costs of £1,800-£2,500.
Absolutely – from Streatham Hill's conservation areas down through SW2's residential streets to Furzedown's garden squares. Regular work takes us throughout SW16 and neighbouring postcodes.
Standard Streatham semi-detached patios complete within 2-3 days. Larger period properties or those requiring additional levelling work might extend to 4-5 days.
All pointing work carries decade-long protection against failure. This covers joint integrity, water resistance and colour stability – particularly important given Streatham's weather variations.
Partial repointing often proves false economy. Once deterioration begins, adjacent joints typically fail within 18 months. Complete repointing ensures uniform protection and avoids patchy appearance.
