Render Cleaning for Gisburn property
Gisburn is about 13 minutes up the road from us, well inside the patch we cover properly. Rendered walls green up first on the shaded north and west elevations, and the streaks almost always start at a sill, a gutter joint or a wall head where rainwater runs the same line. With older stone cottages and converted farm buildings in the area, we match the method to what we find rather than turning up with one machine and using it on everything.
Growth comes back fastest on the north and west facing walls, and around Gisburn that is most of what we get called out to.
Render cleaning is a softwash: low pressure water, no stronger than a garden hose, carrying a biodegradable biocide that kills algae, mould and lichen in the surface of the render. The wall is wetted down, treated, given proper dwell time and then rinsed gently. The growth dies at root level and the discolouration lifts over the following days and weeks. No lance, no rotary head, and no pressure that could open the render or push water behind it.
While we are in Gisburn we regularly pick up work in Barnoldswick, Downham, Chatburn and Earby, so if a neighbour wants the same job doing we can usually do both in one visit.
Suitable for
- K-Rend and other through-coloured silicone renders
- Monocouche render on newer housing and extensions
- Painted render and pebbledash on older Lancashire property
- Rendered gables, dormers and chimney stacks
- Rendered garden, boundary and retaining walls
- External wall insulation systems where the surface must not be opened
Problems it solves
- Green algae streaking down from sills, window heads and gutter joints
- Red or pink algae patches that look like the wall is staining from inside
- Black spotting and mould on shaded north and west elevations
- White render gone a uniform grey so it no longer matches the trim
- Being told the wall needs repainting or re-rendering when it only needs cleaning
- Damage risk from a general cleaner turning up with a pressure lance
How a Gisburn job runs
Identify the render system
We establish what the wall actually is: K-Rend, another silicone render, monocouche, sand and cement with paint, or an insulated system. The system dictates dilution, dwell time and how the elevation is rinsed.
Protect the surroundings
Planting, lawns, block paving, glazing, timber and garden furniture below the work area are wetted down and sheeted. Wetting plants first is what stops any solution being taken up by the roots.
Test patch where needed
On an older coating, an unusual finish or a colour we have not treated before, we do a small area out of sight first and let it react fully before committing to a whole elevation.
Low pressure application
Biocide is applied at garden hose pressure from the top down, in sections, so no part of the wall dries out before it has had its dwell time. Coverage is even from edge to edge and corner to corner.
Dwell and gentle rinse
The solution is left to work and then rinsed off gently. Some discolouration lifts on the day. Red algae and heavy lichen keep fading for days or weeks afterwards as the dead growth weathers away.
Final walk round
We check the elevation from the ground in daylight, rinse down everything below it, and flag what we noticed: a cracked bead, a blocked weep hole, the leaking gutter joint that caused the streak.
