Horwich back gardens are full of Indian sandstone, riven flags and older stone slabs, and the damp moor-edge position leaves them slick and green for much of the year. We drop the pressure right down for the softer stone and worn pointing so the growth lifts away without pitting the surface or stripping the joints.

Patio cleaning across Horwich
Horwich sits directly beneath Rivington Pike and Winter Hill and gets more rain and damp off the moor than the lower parts of Bolton. That constant moisture, on top of the porous local gritstone, is why north-facing roofs, shaded stone fronts and rendered gables in Horwich grow moss and algae faster than most of Greater Manchester.
Horwich grew up around the railway Loco Works, so much of the older town is tight Pennine gritstone terracing that climbs the slope towards the moor. That quarried stone is porous and textured, holding damp and greening quickly, while the large modern estates around Middlebrook are dominated by silicone and painted render. A single street can shift from delicate stone frontages to hard block paving, so the method has to change house by house.
The Horwich homes we clean most
Gritstone terraces built for the old Loco Works
stone-fronted Victorian semis on the hillside streets
inter-war brick and pebbledash semis
modern rendered new-builds around Middlebrook
larger detached houses on the moorland fringe towards Rivington
What we usually find on Horwich patios
Slippery green algae coating on shaded flags below the hillside
black spot lichen ingrained into natural sandstone
moss creeping into the joints between slabs
washed-out or loose pointing on older stone patios
With so much shade and moisture in these gardens, easing the pressure right down lifts the growth cleanly and keeps a Horwich patio looking its best.

Looking for patio cleaning near you in Horwich?
Send us a few photos with your Horwich postcode and we'll give you a fixed price in writing. Quotes are free and there's no obligation.
Yes. We adapt the method to the surface: soft washing or steam for fragile natural stone, and rotary surface cleaning at controlled pressure for tougher slabs. Any solutions we use are surface-safe and applied only where needed.
Can you remove black spots and deep stains?
Yes. Black spots are embedded lichen and need more than a standard wash. We pre-treat with a specialist solution, then steam or rotary clean, repeating or applying a stronger treatment for stubborn areas.
Will the cleaning affect my garden or plants?
We protect surrounding planting, use biodegradable solutions and targeted application to limit overspray, and rinse everything down afterwards so your garden is left safe and clean.
Do you offer sealing?
Yes. Optional sealing enhances the colour, protects against stains and slows the return of moss and algae. We'll advise whether it suits your surface at quote stage.
How long does a typical patio clean take?
Most residential patios take 2-4 hours from set-up to finish, depending on size, soiling and any extras like sealing. We give a clear estimate at quote stage.
How much does patio cleaning cost?
