Softwashing & Render Restoration for Ballymena Homes
Ballymena and the farms and homes around the Braid valley carry a lot of older render, dash and harling, much of it decades old and laid on lime. Those aged finishes are exactly where a pressure washer causes lasting harm, firing the stones out of the dash and roughening the surface so it grabs dirt faster next time. We work the other way. A low pressure softwash lifts the green growth and the black weathering out of the texture and leaves the render itself untouched. It is the sensible way to freshen an older Ballymena wall without gambling on the very finish you are paying to bring back.
The difference
Green and black gone, render back to bright
This is what a softwash does to tired render. No high pressure, no damage, just the algae and staining lifted at the root. We get the same result on homes across Ballymena.

How we clean render in Ballymena
Why it greens up here
Render in County Antrim spends a lot of the year damp. Rain, shade and the mild Northern Irish climate let algae, lichen and black spotting settle into the surface, and north-facing gables get the worst of it. A jet wash strips the top layer and it is back within months, because the spores are never killed. That is why we do not pressure wash render in Ballymena.
What we actually do
We apply a biocidal softwash at low pressure, closer to a garden hose than a jet wash. It kills the growth at the root and keeps working for days after we leave, so the finish comes back bright and stays clean for three to five years rather than weeks. Most Ballymena homes are done in a single visit, we bring our own water and power, and every job is covered by our public liability insurance. You get a fixed price after a free survey, with no call-out fee.
Local questions
Render cleaning in Ballymena, answered
No. Older lime dash and harling are exactly why we softwash rather than pressure wash. Low pressure clears the growth from the texture without knocking stones loose or eroding the surface underneath.
No. Softwashing works at low pressure, closer to a garden hose than a pressure washer. The cleaning is done by a biocidal solution, not by force, so it lifts algae and staining without eroding the finish or forcing water into the render.
Because we kill the growth at the root rather than just blasting the surface, a softwash typically stays clean for three to five years. Pressure washing only clears the top layer, so it often comes back within six to twelve months.
It depends on the size of the property, the level of growth and the access, but a typical three bed semi starts from around 200 to 400 pounds. We give you a clear fixed price after a free survey, with no call-out fee.
Most homes are treated in a single day. Heavier growth sometimes needs a return visit, because the biocide keeps working and clearing for days after we apply it.
No. We arrive fully self-contained with our own water and power, so there is nothing you need to provide on the day.
It kills what is there now at the root. Render will always be exposed to the Northern Irish weather, so growth returns eventually, but far more slowly than after a pressure wash. Many customers have us back every few years to keep it fresh.
Yes, and those are the walls that need it most. North-facing gables get the least sun and stay damp longest, so they green up fastest. The softwash treats them the same way, just with the right dwell time for heavier growth.
Yes. Older dash and harling finishes clean up really well with a softwash. Because there is no high pressure involved, we clear the growth from the texture without knocking stones or chips loose.
For most Northern Irish homes, every three to five years keeps it looking right. If a wall is heavily shaded or near trees it may green up sooner, and we can advise once we have seen it.
Yes. We are Safewash certified, City and Guilds qualified, COSHH certified and carry two million pounds of public liability insurance. We have been cleaning exteriors across Northern Ireland since 2003.
