Black Spot Lichen Treatment & Patio Cleaning, Ponteland
Patio cleaning across Ponteland: biocide treatment for black spot lichen, gentle cleaning for sandstone and limestone, plus sealing advice. Fully insured team.
Whether it's a small courtyard patio behind a terrace, a large sandstone patio on a newer estate, or a block-paved driveway-turned-patio, the cleaning approach in Ponteland starts with the same question - what's it actually made of, and how bad is the black spot lichen.
We use a softwash biocide treatment first, low-pressure or steam cleaning second, and only bring higher pressure in where the surface can genuinely take it - never as the default. That order matters: pressure without treatment just scatters lichen spores across the rest of the patio.
A patio clean should leave you with stone that looks close to the day it was laid - even colour, no black spot lichen, joints free of moss, and no green slick across the edges where it stays damp. That's the standard we work to on every job in Ponteland.
Block Paving
- Block paving needs the joints treated as much as the block faces - jointing sand harbours moss and weed growth that spreads algae staining across the whole surface if left. We clean the gaps as a distinct step, not just an afterthought.
- Where jointing sand has washed out or gone green and compacted, we can advise on re-sanding once cleaning is done, which helps stop the same growth coming straight back.
Doing It Safely - for the Patio and the Garden
Biocide treatments and cleaning chemicals need careful handling around plants, ponds and lawns, and we're trained in spill management so run-off is controlled rather than left to find its own way into a border or drain. We protect nearby planting before we start.
On the stone itself, safety means not overdoing the pressure - too much force on old pointing or soft sandstone can loosen joints or pit the surface, creating problems that weren't there before. We check the condition of the patio first and clean to what it can actually handle.
Covering Ponteland and Its Neighbourhoods
Ponteland covers a fair spread of ground, including Darras Hall, and we work right across it rather than sticking to one part of town.
Wherever your patio sits within Ponteland, distance within the town itself makes no difference to how we quote or schedule the job.
Victorian Terrace Courtyards and Original Flags
Victorian terraces in Ponteland often still have the original stone flags or early concrete slabs in small rear courtyards, laid long before modern pointing methods. Decades of damp, shade from boundary walls and limited airflow make these some of the worst spots for black spot lichen we see.
The pointing between old flags is frequently lime-based or has been patched over the years, so we're careful with pressure and always flag any joints that look loose or crumbling before we start rather than after.
