That persistent moisture, combined with mild temperatures, creates the perfect breeding ground for algae, moss, lichen and the dreaded black spot that plagues Indian sandstone patios across the region. Over time, these biological growths don't just look unsightly; they create dangerously slippery surfaces, trap moisture against the stone, and can cause permanent discolouration if left untreated. At PB Cleaning Solutions, we specialise in **professional patio cleaning across South Wales**. We work with all patio surface types — from budget concrete slabs to premium Indian sandstone, porcelain tiles and natural flagstone. Our [pressure washing](/services/pressure-washing) equipment and specialist treatments deliver results that transform your outdoor space from a neglected afterthought into the centrepiece of your garden. ## Patio Surface Types We Clean ### Indian Sandstone Patios Indian sandstone is one of the most popular premium patio materials in South Wales, prized for its natural beauty and warm tones. Unfortunately, it's also highly porous and susceptible to black spot — a stubborn lichen-like organism that penetrates the stone's surface. Standard pressure washing alone often fails to remove black spot completely. Our treatment combines specialist chemical application with controlled pressure washing to lift black spot from within the stone, revealing the vibrant colours beneath. ### Concrete Slab Patios Concrete slabs are the most common patio surface in South Wales and respond exceptionally well to professional cleaning. Years of algae, moss and ground-in dirt can make grey slabs look almost black — but our high-pressure cleaning strips away all surface contamination to restore the original concrete finish. Many customers are astonished at the transformation, saying their patio "looks like it was laid yesterday." ### Porcelain and Ceramic Tile Patios Modern porcelain patios are becoming increasingly popular due to their low maintenance and contemporary appearance. While they resist biological growth better than natural stone, they still accumulate dirt in textured surfaces and grout lines. We use appropriate pressure levels and techniques to clean porcelain patios without risking damage to the tiles or disturbing the jointing. ### Natural Flagstone and York Stone Traditional flagstone and York stone patios have beautiful character but require careful cleaning. Excessive pressure can damage the surface texture and lift the natural stone grain. We use a combination of [softwashing](/services/softwashing) techniques and controlled pressure to clean these delicate surfaces safely — preserving their natural beauty while removing all biological growth. ## Black Spot Removal — The South Wales Challenge Black spot is the single most common complaint we hear from patio owners across [Newport](/areas/newport), [Cardiff](/areas/cardiff), [Cwmbran](/areas/cwmbran) and the surrounding areas. These dark, circular marks are caused by a type of lichen that embeds itself into the pores of natural stone. Unlike surface algae, black spot cannot be removed with a standard pressure washer or household cleaning products. Our black spot treatment involves applying a professional-grade solution that penetrates the stone and kills the lichen at its root. After a dwell period, we pressure wash the surface to remove the dead growth and reveal the clean stone beneath. In severe cases, a second application may be needed — but the vast majority of patios show a dramatic improvement after a single treatment. ## Patio Sealing and Long-Term Protection After cleaning, we offer an optional patio sealing service that creates an invisible barrier against moisture, staining and biological regrowth. A quality sealant can keep your patio looking clean for 3–5 years, compared to 12–18 months without protection. Sealing is particularly beneficial for Indian sandstone and natural stone patios, which are most vulnerable to black spot recurrence. We use breathable, matt-finish sealants that protect the stone without changing its natural appearance. The sealant allows moisture to evaporate from within the stone while preventing new growth from taking hold on the surface — a crucial detail that cheaper, film-forming sealants often get wrong. ## Areas We Cover for Patio Cleaning We provide professional patio cleaning throughout South Wales, including [Newport](/areas/newport), [Cardiff](/areas/cardiff), [Cwmbran](/areas/cwmbran), [Pontypool](/areas/pontypool), [Caerphilly](/areas/caerphilly), [Chepstow](/areas/chepstow), [Caldicot](/areas/caldicot), [Magor](/areas/magor) and [Bristol](/areas/bristol). Whether you're in a town centre terrace or a rural farmhouse, our mobile team brings everything needed for a complete patio transformation. ## Combine Patio Cleaning with Other Services Most customers who book patio cleaning also take advantage of our [driveway cleaning](/services/driveway-cleaning) service — cleaning both areas in a single visit saves time and money. We also offer [gutter cleaning](/services/gutter-cleaning), [window cleaning](/services/window-cleaning) and [conservatory cleaning](/services/conservatory-cleaning) for a complete exterior property refresh. ## How Much Does Patio Cleaning Cost? Patio cleaning prices depend on the surface area, material type, level of soiling and whether sealing is required. A typical rear patio (15–25 sqm) in South Wales costs between £120 and £350 to clean professionally. Black spot treatment and sealing are priced as add-ons.

No. We adjust pressure and technique for each surface type. ### Can you remove black spot from Indian sandstone? Yes — we use specialist treatments to lift black spot effectively. ### How long until I can use my patio after cleaning? Same day. If sealed, 24 hours before replacing furniture. ### Do you clean patio furniture too? We focus on hard surfaces but can rinse furniture as part of the job. ### Can you clean between paving slabs?
