Wall cleaning uses a softwash approach, biocide chemistry to kill algae, moss and lichen, plus a controlled, low-pressure rinse to lift atmospheric grime, salt bloom and streaking. The right method depends on the substrate: fired brick, natural stone, reconstituted stone, painted masonry and rendered brick all need different chemistry and pressure. ### Who it's for Homeowners with green streaking, algae banding or blackened brick facades; period-property owners preparing walls for repointing, painting or lime-render work; commercial and heritage sites where the facade sets the first impression. ### When you need it Green tinge on north-facing walls, black algae streaks running from gutter drips or hopper leaks, lichen scabs on stone, salt efflorescence blooming through brick, dulled or discoloured paintwork, all cleanable, all easier the sooner they're treated. ### Why it needs a specialist Old-school pressure blasting and sandblasting damage historic brick, chip natural stone and blow pointing out of the joints. Softwash sidesteps all of that by leaning on chemistry, the right biocide, the right dwell, the right rinse, instead of blunt force. ### How we quote For most work we prefer to visit in person so the quote is accurate, no online guesswork. Roof cleans can also be quoted from satellite imagery when a visit isn't convenient. Payment is on completion, cash or bank transfer, no deposits. Why Waiting Costs More ## Left untreated, small problems get expensive. Wall staining is the most visible sign of neglect on a property. It also gets progressively harder to shift the longer it's left, because algae and grime bed into porous substrates. ### What happens if it's ignored - Algae and moss on masonry hold moisture, accelerating freeze-thaw damage that pushes pointing out and can spall brick faces. - Lichen on natural stone etches into the surface. Left long enough, some staining becomes a permanent feature rather than a cleanable one. - Painted masonry fails from underneath when algae is left on the film, you end up needing a full repaint rather than a clean. - Salt bloom (efflorescence) is a red flag for moisture problems; ignored, it can indicate cavity issues, failed damp coursing or blocked weep holes. - Dulled, streaked facades knock kerb appeal and visible value at exactly the moments you want them highest, pre-sale, valuation, letting. ### Common DIY mistakes - High-pressure blasting historic brick. Pressure that clears the algae also blows out the softer lime pointing between joints. - Sandblasting or grit-blasting facades. Removes the fire-skin of hand-made brick and dramatically shortens the wall's life. - Applying supermarket 'wall & fence cleaner', too dilute to kill algae at the root, wrong chemistry for many stones. - Ignoring water sources. If the streak is from a leaking hopper, cleaning without fixing the leak means the streak returns next winter. - Painting over dirty or algae-covered walls. The paint fails from the underside within a season. Our Process ## A methodical system, not a rushed hose-down. 01 ### On-site inspection We identify substrate, fired brick, hand-made brick, natural stone, painted masonry, rendered brick, and check pointing condition and water sources causing streaking. 02 ### Protection & access Ground protection, planting cover, downpipe protection all set up. IPAF-certified access where needed. RAMS provided for commercial jobs in advance. 03 ### Biocide softwash Correct-strength biocide applied at low pressure across the full facade. Dwell time to kill algae, moss and lichen at the root. 04 ### Controlled rinse Low-pressure rinse with clean water, lifting suspended grime without stressing pointing or paint film. 05 ### Second treatment Final biocide pass to lock in long-term protection. Walk-around with the owner and photographs before payment on completion. The Payoff ## What you actually get for the money. ### Substrate-appropriate method Brick, stone, reconstituted stone and painted masonry all get their own chemistry and pressure. No one-size-fits-all wash. ### Pointing preserved Softwash doesn't blow out pointing the way high-pressure blasting does, critical on period properties. ### Long-lasting result Biocide kills at the root and prevents regrowth. Typical Dorset walls stay visibly clean for years. ### Painted walls treated safely Sound paint is preserved; failing paint is identified so you can decide whether to clean or repaint. ### Working-at-height certified IPAF and rescue trained. Insurance certificates, RAMS and method statements provided for commercial sign-off. ### One point of contact Adam owns the business and is on every job, no scheduling handoff, no middle-manager, no chasing the office. Deep Detail ## Materials, methods and variations we handle. Every surface behaves differently under pressure, water temperature and chemistry. Here's the technical detail behind the work, the reason we don't quote sight-unseen for most jobs. ### Wall substrates we clean Standard fired brick is the most common Dorset facade, modern estates in Poole, Bournemouth suburbs, and infill developments. Hand-made and stock brick on older properties is softer and needs correspondingly softer handling. Purbeck stone and Portland stone facades, big presence around Weymouth, Wareham and Swanage, need chemistry chosen for calcareous stone. Reconstituted stone is essentially concrete and takes a firmer approach. Painted masonry is chosen based on the paint film's condition. Rendered brick sits between wall and render territory. - Standard fired brick facades - Hand-made and stock brick (period property) - Purbeck stone and Portland stone - Reconstituted stone - Painted masonry - Rendered brick and lime-plastered walls ### Softwash vs pressure blasting The single fastest way to damage a period brick facade is to point a high-pressure lance at it. It clears the algae, yes, and it also strips the fire-skin off hand-made brick and blows softer lime pointing out of the joints. Softwash uses biocide chemistry with a low-pressure rinse, the algae is killed by the chemistry, not the water pressure. This is the method conservation officers and heritage bodies specify, and it's the method that keeps you on the right side of listed-building consent where relevant. ### Efflorescence and salt bloom White powdery deposits on brick, efflorescence, are salt migrating out of the brick as moisture moves through the wall. We can remove the visible bloom, but the underlying cause is a moisture path (cavity, damp coursing, missing weep holes) that isn't a cleaning problem. As part of every wall clean where we see efflorescence, we'll be honest about what's causing it and whether cleaning alone will hold, or whether you need to loop in a damp specialist. ### Painted walls, clean or repaint? If the paint film is sound, a proper wall clean brings it back a long way, algae removed, chalking dust washed off, colour restored. If the paint is failing (flaking, blistering, powdery to touch), cleaning will expose that and it's usually the point at which a full repaint makes more sense than a clean. We'll assess honestly at quote stage and tell you which path saves you money. ### Residential vs commercial Domestic wall cleaning is typically a one or two day job depending on facade area and access. Commercial and heritage work, retail units, offices, church walls, listed buildings, is scheduled around access windows and often involves MEWP hire, RAMS documentation, method statements and coordination with a site H&S officer. All available as standard. Common Questions ## Straight answers, no jargon. Something not covered here?

Ask a question Call How much does wall cleaning cost?Priced per property based on facade area, substrate, access and condition. Book a free on-site quote for a firm written price. Will pressure washing damage my brick?High-pressure blasting damages hand-made brick and blows out pointing. We softwash, chemistry first, low-pressure rinse, which is the conservation-approved method. How long does the result last?Under normal Dorset conditions, biocide-treated walls typically stay visibly clean for several years. Regrowth depends on shade, tree cover and water sources like leaking gutters. Can you clean painted walls without damaging the paint?Yes if the paint is sound. If the paint film is failing, cleaning will highlight that, we'll tell you at quote stage whether a clean or a repaint is the right call. Do you work on listed buildings?Yes, softwash is the method conservation officers and heritage bodies specify. We provide method statements and can liaise with your architect or conservation officer as needed. What about efflorescence (white salt bloom)?We can remove the visible bloom, but efflorescence is a moisture indicator, we'll flag it and be honest about whether cleaning alone will hold or whether a damp specialist should also look at it. How long does the job take?One to two days for most domestic properties. Commercial and heritage work is scheduled individually around access. Is it safe for planting and pets?Yes when applied correctly. We cover planting near the wall and ask that pets stay inside during application and dwell time. Do you cover Bournemouth, Poole and heritage sites in Wareham and Swanage?Yes, most of our work is Bournemouth and Poole, with regular jobs across Wareham, Weymouth, Dorchester, Swanage, Ferndown. How quickly can you book me in?Adam replies within 30 minutes during contact hours. Wall cleans are usually scheduled 1–3 weeks out depending on weather.
