Exterior Cleaning FAQs

Boroughs right across South London, including Clapham, Dulwich, Wandsworth, Battersea, Balham, Bromley, Croydon, Greenwich and Streatham, and the streets between. We are a mobile service, so we come to you. Tell us your postcode and we will confirm we cover it.

Three ways: call 020 8050 5955, fill in the contact form, or send us a few photos. For most cleans, like windows, gutters or a driveway, we can give you a fixed price straight from the photos. For bigger jobs, like a roof or a whole-house render clean, we pop round to see it first. Free, no obligation.

Not for outside work, as long as we can reach the back of the property safely. We send a message before each visit and you pay afterwards. The only time you need to be in is for an interior window clean, so we can get inside.

From the ground. We use water-fed poles for upstairs windows and conservatory roofs, and a gutter vacuum with a camera on the pole for gutters. No ladders leaning on your brickwork and no walking on your roof, which is safer for us and for the building.

For most South London homes, every four to eight weeks keeps the glass looking right all year. Houses on busier roads or under trees pick up grime faster, so a four-weekly round suits them, while a quieter street is fine at eight or twelve weeks. We suggest a frequency when we quote and you can change it whenever you like.

Yes, on request. Most regular rounds are exterior only, which is what keeps the price down, but we are happy to do insides as a one-off or on a longer cycle. Tell us when you book and we will price both.

It is a soft brush on a long pole fed with filtered, mineral-free water. The brush lifts the dirt and the pure water rinses it off, then the glass dries on its own with no spots or smears, because there is nothing in the water to leave a mark. It also means we reach upper-floor windows from the ground, with no ladders against your house.

Once a year is right for most homes, usually in late autumn once the leaves are down. If you have mature trees nearby, twice a year keeps them clear. A blocked gutter overflows down the wall, and that is what leads to damp inside, so it is the cheapest bit of maintenance a house needs.

We use a gutter vacuum: a long pole with a vacuum head and a small camera on the end. It pulls out the leaves, moss and silt while we watch the camera feed, so we clear the whole run without a ladder against your house. The camera gives us before-and-after photos of each run, and we send them over with the invoice.

Blasting a roof with a pressure washer is exactly what you should not do. High pressure strips the surface off the tiles, forces water underneath, and can crack older clay and concrete. We scrape the moss off and then soft wash, applying a biocide at low pressure that kills the moss and algae at the root so it weathers away over the following weeks. The tiles are left intact.

Moss and algae live on damp and shade, so north-facing and tree-covered surfaces get it worst. On a roof it is not just cosmetic: thick moss holds water against the tiles and drops into the gutters and downpipes, blocking them. Clearing and treating it protects the surface as well as tidying it up.

Not the way we do it. We match the pressure and the head to the surface, and on block paving we always brush fresh kiln-dried sand back into the joints afterwards, because blasting the old sand out is what loosens the blocks. On softer stone and decking we use a gentler approach so we do not pit or fur the surface.

A clean lasts a good while, but moss and algae are about damp and shade, so a north-facing or tree-covered area greens up sooner than an open sunny one. If you want it to stay clean longer, we can apply a treatment or a sealer that holds it off for a couple of years.

Render and K-rend have a thin coloured surface that high pressure tears straight off, leaving patches you cannot fix without re-rendering. Soft washing uses a low-pressure spray and a biocide that breaks down the algae and grime, so the wall comes clean without being damaged, and it stays clean far longer than a blast would.

A fixed price up front, worked out from a few photos or a quick look, not an hourly rate. As a rough guide, window cleaning is from around £18 a visit, gutters from around £60, a driveway or patio from around £150, and a roof from around £400, with the final figure set by size, access and how much there is to shift. We confirm the price before we start.

No deposit for a standard clean. You pay after the job is done. For larger one-off work we agree the terms in writing first, but you are never paying up front for a window or gutter round.

By bank transfer or card after the visit. We send a message before each visit and the invoice afterwards, so there is nothing to sort out on the doorstep.
