What good wall cleaning & softwash looks like here

  1. 1Two passes on the Gunnislake-facing elevation where very-exposed weather drives the worst staining
  2. 2Lower biocide concentration around old mortar joints on estuary village properties in PL18
  3. 3Pre-rinse on plant borders typical of estuary village gardens before any product goes up
  4. 4Window pre-wet so over-spray rinses clean - important on older glass in miners' terraces and waterfront cottages
  5. 5Plinth and damp-course area always rinsed last on estuary village stock in Calstock

Materials & methods we'd use here

Most Calstock properties we treat have granite and painted render walls and a Cornish slate roof. That changes a few of the choices we'd make.

  • Method

    Sodium hypochlorite mixed to a strength suitable for granite and painted render - never neat on estuary village stock

  • Method

    Quaternary ammonium surfactant added so biocide clings to your granite and painted render elevation in Calstock

  • Method

    Low-volume rinse from a high-flow tank - critical on the softer finishes you see across miners' terraces and waterfront cottages

  • Method

    Suitable for K-Rend, Weber and silicone renders — common on the newer estuary village properties around PL18

What Calstock owners ring us about

  • Streaking down granite and painted render that's worse on the Gunnislake-facing elevation than the rest of the house
  • Algae returning fast on shaded walls thanks to Calstock's very-exposed setting
  • Render staining at the plinth on estuary village properties along the local lanes off A390
  • Black biofilm on granite and painted render where the prevailing wind blows in off Under the tall Calstock viaduct on a Tamar meander
  • Discolouration where downpipes meet granite and painted render - near-universal on estuary village properties this far from PL3
