How often exterior cleaning is usually needed

Frequency depends on shade, trees, traffic, drainage and how quickly organic growth returns.

Driveways: usually every 12–24 months; shaded block paving may need yearly attention.

Patios and paths: usually every 12–18 months, or sooner if they become slippery.

Gutters: usually once or twice a year, especially after autumn leaf fall.

Fascias, soffits and garage doors: usually every 12–24 months for kerb appeal.

Decking: often every 6–12 months because it can become slippery quickly.

What chemicals are used for soft washing?

Where suitable, soft washing may use a controlled sodium hypochlorite based solution, commonly called hypo, to treat organic growth such as algae, moss residue and green staining. It can be very effective, but it is not the right choice for every surface.

Other jobs may only need pressure washing, water-fed cleaning, detergent or a gentler treatment. The method depends on the surface, staining, drainage, nearby plants, pets, ponds and weather conditions.

Important: chemical strength, dwell time and rinsing must be controlled. The aim is to use the safest effective method for the job, not the strongest possible mix.

Driveway cleaning

Price depends on driveway size, surface type, weeds, moss, staining, drainage and whether re-sanding is needed for block paving.

Patio cleaning

Patio quotes depend on the material, access, black spot, algae, furniture, drainage and how much detail work is needed around edges.

Gutter cleaning

Gutter prices depend on property height, access, gutter length, blockages and whether there are extensions, conservatories or awkward rooflines.

Full exterior refresh

Combined jobs can be better value when several areas are cleaned on the same visit, such as driveway, patio, gutters, fascias or garage doors.

Common questions

Can you give a price without visiting?

Usually yes. Clear photos, postcode and access details often allow a fast quote by WhatsApp.

Why not list fixed prices?

A small clear patio and a large moss-covered driveway are very different jobs. Photo quotes keep pricing fair and realistic.
