Glasgow's weather does most of the damage before a cleaner ever turns up. It rains often, the air stays damp, and moss, algae and lichen take hold fast on anything north-facing or shaded. That makes exterior cleaning here less of a luxury and more of a maintenance job. In Giffnock, Newton Mearns and Bearsden, the typical call is a block paving driveway gone green and slippery, cleaned, re-sanded with kiln-dried jointing sand and sealed so the weeds stay out. Patios are the next most common job, whether that's Indian sandstone that's turned black in the pores, porcelain with a film of algae, or old concrete slabs. Across the Southside and the West End, tenement and sandstone properties need gentle brick and stone cleaning, while 1930s semis and post-war roughcast homes in Knightswood and Jordanhill lean towards render cleaning. K Rend, silicone and painted render all streak with algae, and each needs a low-pressure wash with a biocide rather than a blast. Roofs are the big one. Concrete and clay tiles, plus slate, get soft washed with a biocide to kill moss and lichen at the root, because a pressure washer strips the surface, forces water under laps and shortens the life of the tile. Gutter clearing, fascia and soffit cleaning and decking refreshes are usually bundled into the same visit, which is why many firms quote them together.
The businesses on this page are drawn from public business listings and ranked by public review rating and review count, with a small lift for those that show a working website and phone number. We read each business's homepage and confirm that exterior cleaning is what they primarily offer, which keeps unrelated trades off the page. Listings flagged as permanently closed are removed automatically. Where you see a Trust Verified badge, that business has additionally passed our full verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information. Our How We Verify page has the full list. Businesses without the badge haven't been independently verified by us, so those checks are yours to make before you book.
Get two or three quotes, and make sure each one describes the same job. A quote that just says driveway clean is not the same as one that covers jet washing, re-sanding and two coats of sealant. Ask which method they'll use on your surface, and be wary of anyone planning to pressure wash a tiled roof. Ask for proof of public liability insurance, since a pressure washer can chip render, crack a conservatory seal or send grit through a window. Check whether they use a biocide on roofs and render, how they'll deal with run-off and drains, and whether they carry any relevant trade accreditation. Ask about water supply too. Some firms bring their own tank, others need access to your outside tap. Get the price, the sealant type and any aftercare advice in writing, and read recent online reviews for photos of finished jobs.

It depends on the surface and the size. A block paving driveway of around 30 to 40 square metres typically costs £250 to £500 to clean, and £400 to £800 once re-sanding and sealing are added. Patios run roughly £4 to £8 per square metre, with Indian sandstone and porcelain at the higher end. A soft-wash roof clean on a semi-detached home is usually £400 to £900. Gutter clearing is £60 to £150 for most houses, and render cleaning is £5 to £10 per square metre. Access, scaffolding and how bad the growth is all push the price up. Getting two or three quotes is normal, and many firms discount when you bundle jobs.
Why is a roof soft washed rather than pressure washed?
A pressure washer blasts the granular surface off concrete tiles, forces water up under the overlaps and can crack older clay or slate. That shortens the life of the roof and can lead to leaks in the loft. Soft washing applies a biocide at low pressure, which kills moss, algae and lichen at the root. The dead growth then washes away over the following weeks with the rain. A good roof clean takes a day for an average house, and results keep improving for a few weeks afterwards. Expect the roof to stay clean for three to five years in a damp, shaded spot.
What's the best method for block paving, patios and decking?
Block paving is jet washed with a surface cleaner, then re-sanded with kiln-dried jointing sand and sealed, which locks the blocks and slows weeds and moss. Indian sandstone needs a lower pressure and a careful hand, since a hard blast pits the surface and opens the pores. Porcelain is tougher but can scratch from grit, so a rotary surface cleaner with a mild detergent works best. Standard concrete slabs take a stronger clean. Decking is best cleaned with a brush and a decking cleaner, as pressure washing raises the grain and leaves furry splinters. Ask your cleaner to name the method for your surface.
How often should I get my driveway, roof and render cleaned?
In Glasgow's damp climate, a driveway or patio usually needs cleaning every one to two years, and sealed block paving can stretch to three. Roofs and render are less frequent, typically every three to five years, though a shaded north-facing roof or a house next to trees may need it sooner. Gutters should be cleared at least once a year, ideally in autumn after the leaves drop. Decking benefits from a yearly clean and a fresh coat of treatment every couple of years. Annual cleaning is cheaper in the long run than waiting until the growth is severe.
Will cleaning damage my render or brick and stone?
Done properly, no. Render, including K Rend, silicone and painted finishes, should be low-pressure washed with a biocide, which lifts the algae and black streaks without stripping paint or cracking the finish. Hard pressure on silicone render can damage the water-repelling layer. Old sandstone and soft brick are particularly vulnerable, as blasting removes the face of the stone and leaves it more porous and prone to frost damage. Ask for a gentle, low-pressure approach and a test patch in an unobtrusive spot. If a firm suggests a high-pressure blast on a tenement or period property, think twice.
How do I choose between exterior cleaning firms?
Start by asking for proof of public liability insurance and check the cover amount. Ask whether they hold any relevant trade accreditation, and look for recent online reviews with before-and-after photos of jobs like yours. Make sure they can explain, in plain terms, why they'd use a particular method on your roof, render or paving. Get the quote in writing, with the sealant type, number of coats and any biocide named. Be cautious of anyone asking for a large cash deposit or pressing you to decide on the doorstep. A Trust Verified badge means we've completed our full checks, but for any business without one, those checks are yours to make.
