Patio cleaning · Dublin
Slippery moss and black stains turn a lovely patio into a no-go zone. We lift years of algae, lichen and grime from every kind of slab, so your patio is safe, clean and ready for summer evenings again.

Those stubborn dark spots normal washing won't shift? We use a specialist treatment that removes black spot and lichen at the source, not just the surface.
We clean the joints, treat the moss and leave your patio safe underfoot — so it's ready for the table, the BBQ and the good weather.

"Kirk cleaned and treated our back patio (sandstone slabs) and the slabs are like brand new again. All the black spot gone. Excellent quality work, highly recommend Reflect."
"Our patio was green and slippery and honestly a bit of an eyesore. Reflect brought it back to life — you'd think the slabs were new. Delighted, and reasonably priced too."
"Brilliant job on the patio and the joints re-sanded after. Great attention to detail and left everything spotless and tidy. Would happily recommend to anyone in Dublin."

The most effective method is power washing with the right pressure for your slab type, followed by treating any moss, algae and black spot at the root. Brushing fresh kiln-dried sand back into the joints afterwards keeps weeds down and finishes it neatly. For delicate stone like sandstone or porcelain, a gentler technique is used to avoid pitting the surface.
We power wash to lift the surface growth, then apply a moss and algae treatment that kills the spores living in the stone. This is the key step — without it, the green comes back within weeks. The treatment keeps your patio cleaner for much longer than washing alone.
Yes. Black spot (the stubborn dark lichen that normal washing won't shift) needs a specialist chemical treatment rather than just pressure. We apply it, let it work, and remove the marks at the source. It's one of the most common patio problems we're called out for in Dublin.
Yes, and these need care. Sandstone is soft and porous, so too much pressure pits and marks it — we use a lower pressure and the right nozzle. Porcelain is hard-wearing but the joints and surface film still need proper cleaning. We match the method to your specific material.
A small patio starts from around €120, a standard garden patio from around €200, and a full clean with sealing from around €400. The exact price depends on the size, slab type and how much moss or black spot there is. You'll always get a fixed quote before we start.
Sealing isn't essential but it's worth it for many patios. A sealant helps repel stains, slows down moss and algae returning, and can enhance the colour of natural stone. We can clean and seal in one visit if you'd like the longer-lasting finish.
Not when it's done correctly. Damage happens when high pressure is used on soft or old stone. We assess your slabs first and adjust the pressure and distance — cleaning deeply on hard surfaces, and working more gently on delicate stone like sandstone or limestone.
Once a year keeps most Dublin patios looking their best, ideally in spring before the summer or in autumn after the leaves. Shaded, north-facing patios grow moss faster and may need it more often. Sealing after cleaning extends the time between washes.
