Shared-valley roof leaks
E17 terraces share valley gutters between properties. Debris in one property's section overflows into the next — full-run vacuum clearance is the only fix.
Walthamstow's E17 housing stock is overwhelmingly Victorian and Edwardian — long terraces, shared valley roofs, half-round cast-iron gutters and front-bay slate. Generic exterior cleaners get this wrong. We specialise in it: tile-safe steam, vacuum-cleared shared runs, biocide on Victorian brick.

E17 is one of London's most architecturally consistent postcodes — long Victorian and Edwardian terraces with shared valley roofs, slate fronts, clay-tile rears, and original half-round cast-iron gutters. The wrong cleaning method on any of these is expensive. We know the terrace pattern intimately.

Issues specific to Walthamstow's property types, age and microclimate — and how we fix them properly.
E17 terraces share valley gutters between properties. Debris in one property's section overflows into the next — full-run vacuum clearance is the only fix.
Victorian slate is brittle and porous. Pressure-washing damages it; biocide soft-wash is the only safe method.
Original half-round cast-iron gutters in conservation areas need vacuum clearance without dislodging the joints — we use low-suction kit and work gently.
Decades of urban soot plus algae on north-facing fronts respond to gentle biocide, not chemical strippers.
William Morris and Lloyd Park conservation areas restrict cleaning methods. We use Listed-safe specs on every conservation job.
