Softwashing for Great Harwood property
We are about 19 minutes from Great Harwood, so a quote visit does not need to wait for a gap in the diary. Softwashing is the safest method for the mix of render, roof tile and stonework found on most properties here, because it cleans with biocide rather than force and leaves the surface itself untouched. Housing across BB6 covers period stone alongside newer render-fronted housing, which is why we look at the actual surface before quoting rather than pricing off a photograph.
Growth comes back fastest on the north and west facing walls, and around Great Harwood that is most of what we get called out to.
Softwashing is exterior cleaning done with chemistry rather than force. Water is applied at low pressure, similar to a garden hose, carrying a biodegradable biocide that is usually sodium hypochlorite based with a surfactant added so it clings to vertical surfaces. It kills algae, lichen and moss at the root rather than simply knocking the top growth off, so regrowth is slow. Because there is no pressure behind it, there is no risk of driving water behind render, raking out mortar or etching soft stone.
While we are in Great Harwood we regularly pick up work in Clayton-le-Moors, Rishton, Accrington and Read, so if a neighbour wants the same job doing we can usually do both in one visit.

How a Great Harwood job runs
Survey and free quote
We look at every elevation, identify the substrate, check the condition of the render, pointing and seals, and note anything that needs protecting. The quote is free and carries no obligation.
Protecting the surroundings
Plants, lawns, ponds and gravel near the work are wetted down or sheeted. Windows, vents and any open joints are checked and covered where needed, so nothing takes solution that should not.
Applying the softwash
The biocide is mixed to a strength matched to that surface and applied at low pressure from the ground or from safe access. We work in sections so that no area dries out before it has dwelled.
Dwell time
The solution stays on the surface long enough to penetrate the growth and kill it at the root. On heavy lichen this single step decides whether the result holds for years or for months.
Rinse and tidy
Surfaces are rinsed at low pressure, run off is directed away from planting and ponds, and we clear down. Glass and sills are wiped where the work has touched them.
Weathering out
Dead growth carries on breaking down and washing off in the rain over the following weeks. Roofs and heavy lichen keep improving for a month or more after we have left site.
