Wall & Render Cleaning in Brighton & Hove
Safe, effective soft washing for exterior walls, render, brick and boundary walls — removing black spot algae, moss and grime without damaging the surface underneath.
Restore Your Walls Without Damage
Render, brick and stone walls are vulnerable to black spot algae, green algae and general atmospheric grime, especially in shaded or coastal locations around Brighton & Hove. High pressure washing alone can drive water into render and cause long-term damage, so we use a soft washing approach where appropriate.
Soft washing combines gentle, low-pressure rinsing with a specialist biocide treatment that kills algae and moss at the root, giving longer-lasting results than pressure washing alone.
Black spot algae in particular is a common sight on render across the South Coast. It thrives in damp, shaded conditions — north-facing elevations, walls close to trees or hedging, and properties near the sea are all especially prone to it. Beyond the cosmetic issue, a heavily colonised wall can trap additional moisture against the surface, which over time may contribute to render deterioration. Treating it properly, rather than simply blasting it away, is what keeps it from returning as quickly.
What We Clean
Surfaces We Treat
Every exterior wall surface behaves differently under pressure and chemical treatment, so we choose our approach based on the material in front of us — never a one-size-fits-all blast.
Rendered Walls
Modern render finishes — smooth, textured or coloured — are cleaned using low-pressure soft washing, protecting the render coat while removing algae, black spot staining and general discolouration.
Brick & Stonework
Exterior brick and natural stone walls, including period Brighton townhouse frontages, are cleaned to remove moss, algae and general dirt build-up, restoring their natural colour and character.
Pebbledash
Pebbledash traps dirt and algae in its rough aggregate surface. A careful, controlled clean lifts this build-up without dislodging the pebbles or damaging the underlying render.
Garden & Boundary Walls
Low garden walls, retaining walls and boundary walls are cleaned alongside your driveway or patio where useful, for a consistently fresh finish across the whole property.
Fascias & Soffits
We can clean fascias and soffits at the same time as your gutter clean, removing algae streaks and general grime from the roofline for a genuinely finished, well-maintained look.
Cladding
UPVC and timber cladding are cleaned carefully to lift dirt, algae and green staining without damaging the surface, seams or finish of the panels.
Our Approach
Soft Washing vs Pressure Washing
Choosing the right method for the surface is the single biggest factor in getting a safe, long-lasting result on walls and render.
Soft Washing
Low-pressure application of a specialist cleaning solution that kills algae, moss and mould at the root rather than simply removing what's visible on the surface. The safest option for render, pebbledash and delicate wall finishes, with results that last significantly longer than pressure washing alone — often 12 months or more.
Pressure Washing
Higher-pressure water used on tougher, more resilient surfaces like exposed brick and natural stone, where a deeper clean is needed and the material can safely handle it without risk of water ingress or surface erosion.
In practice, many jobs use a combination of both — a gentle soft wash treatment on render and pebbledash sections, alongside a more thorough pressure wash on brick plinths, steps or boundary walls. We assess each property individually rather than applying a single method across every surface.
Signs Your Walls Need Attention
When Should You Book a Wall Clean?
- Black or green staining spreading across render, particularly on shaded or north-facing walls
- Visible moss or algae on brickwork, stonework or boundary walls
- A general dull, grey appearance compared to neighbouring or newer render
- Streaking below gutters or roofline, often a sign gutters need clearing too
- Preparing your property for sale, letting, or a special occasion
FAQs
Wall & Render Cleaning Questions
Is soft washing safe for render?
Yes — soft washing is specifically designed to be a safe, low-pressure method for render, pebbledash and other delicate finishes, avoiding the risk of water ingress that high pressure washing can cause on these materials.
How long do results last?
Because soft washing treats algae and moss at the root rather than just removing what's visible, results typically last significantly longer than a pressure wash alone — often 12 months or more, depending on the wall's exposure to shade and damp.
Can I combine a wall clean with a driveway or patio clean?
Absolutely — many customers book a wall, driveway and patio clean together for a complete exterior refresh in one visit. Ask us for a combined quote when you get in touch.
Will cleaning damage my render or paintwork?
When the correct method is used for the surface, no. We assess the render or paint condition before starting and choose soft washing wherever there's any risk that higher pressure could cause damage.
Do you treat the algae so it doesn't come straight back?
Yes — our soft washing treatment is designed to kill algae, moss and mould at the root, not just rinse away what's visible, which is why results last considerably longer than a simple pressure wash.
