Transform your outdoor living space with our specialist patio cleaning and restoration services. We remove stubborn algae, black lichen spots, weed growth, and ground-in grime from sandstone, Indian stone, porcelain, slate, and concrete patio slabs to make your garden safe and vibrant.
Complete the form below and we’ll be in touch shortly.
Yes. Natural stone like Indian sandstone often develops stubborn black lichen spots (Verrucaria nigrescens) that root deep into the stone pores and cannot be removed by standard water pressure alone. We apply specialized biocide treatments and targeted surface-cleaning solutions that break down these deep biological roots, lifting dark spots and restoring the natural, vibrant color of your paving slabs.
Standard high-pressure lances can etch delicate natural stone surfaces, strip surface layers, or blast out mortar joints. We adjust our cleaning methods to suit your specific patio material, utilizing flat-surface rotary cleaners with controlled pressure and softwash biocide solutions. This ensures an even, deep clean without gouging sandstone or damaging delicate porcelain tile coatings.
We address weed growth at every stage of the restoration process. First, we clear existing weeds, roots, and moss from the joint channels during the deep wash. Next, we apply a fungicidal biocide treatment to destroy hidden spores deep within the joint substrate. Finally, we offer re-pointing or jointing sand replacement options that seal the gaps and prevent weed seeds from taking root.
Porcelain slabs require a gentle touch to preserve their textured anti-slip coating and specialized jointing compounds. We use warm, low-pressure softwashing techniques combined with specialized, non-abrasive detergents designed specifically for porcelain. This lifts ground-in dirt, algae, and leaf staining without scratching or dulling the tile surface.
Yes. High-pressure cleaning or age often washes away old, crumbling sand-and-cement mortar or jointing compound. Once your patio is clean and fully dry, we can re-point the joints using modern polymeric jointing mortars or brush-in compounds, creating a durable, weed-resistant, and weather-proof barrier between your slabs.
We highly recommend sealing natural stone and porous concrete patios. An exterior impregnating or surface sealer creates a breathable, water-repellent barrier that shields your paving against frost damage, oil spills, barbecue grease, and leaf staining. Sealing also locks in natural stone colors and makes future routine maintenance significantly easier.
Yes, property safety is our priority. We exclusively use fully compliant, biodegradable cleaning agents. Before applying any specialist treatments, we thoroughly saturate all adjacent lawn borders, flowerbeds, and plants with fresh water to act as a shield. Once the patio surface has dried completely, it is totally safe for children and domestic pets.
We control and direct dirty water runoff away from your garden beds, surrounding lawns, and home foundations toward active surface drains using squeegees and containment barriers. We carry out a complete clean-down of all adjacent walls, doors, and glass before completing the job, leaving your garden spotless.
You can walk on the patio immediately after a standard clean and rinse. However, if we carry out joint re-pointing or apply a protective surface sealer, we advise keeping patio furniture, plant pots, and heavy foot traffic off the area for 24 to 48 hours to allow the compounds and sealants to cure fully.
Our pricing is completely transparent and based on the total surface area (square meters) of your patio, the type of paving material (e.g., block, sandstone, porcelain, concrete), the severity of black spot or algae infestation, and whether re-pointing or sealing is required. We provide instant, accurate fixed quotes using high-resolution aerial mapping tools.
Your patio should be the focal point of your outdoor space, perfect for relaxing and entertaining. However, Central Scotland’s damp, shady climate creates ideal conditions for green algae, moss, and dark lichen spots to thrive on outdoor paving. Over time, these organic growths turn beautiful stone surfaces into slick, unsightly hazards underfoot, making your garden uninviting and unsafe.
Our professional patio cleaning service restores your stone, concrete, or porcelain paving back to its original beauty. Utilizing commercial rotary surface cleaners and targeted softwash biocides, we safely strip away embedded dirt, black lichen spots, and slippery algae without damaging the stone face. We revitalize your entire patio space, creating a clean, safe environment for your family to enjoy. For roof cleaning in Glasgow, choose Outside Clean.

By targeting organic spores deep inside stone pores, our softwash treatments keep green algae and lichen from quickly returning.

Attempting to clean patio slabs with domestic power washers often leads to uneven zebra-striping, gouged stone faces, and blown-out jointing mortar.
