Render cleaning removes organic growth (algae, lichen, moss), atmospheric pollution, and biological staining from rendered and masonry surfaces. Left untreated, these contaminants degrade the substrate, trap moisture, and accelerate weathering—reducing both appearance and structural integrity.

Yes. High-pressure washing (>100 bar) can erode render surfaces, force water behind the facade, and void manufacturer warranties. Our low-pressure biocide method (<40 bar) cleans at the molecular level without mechanical stress.

Typically 3-5 years depending on exposure, orientation, and local environment. North-facing elevations and shaded areas may require more frequent treatment. We offer maintenance contracts with scheduled re-treatment to maintain long-term protection.

Cleaning restores the original surface by removing contaminants. Painting covers them. If the substrate is sound, cleaning is more cost-effective, breathable, and sustainable. We only recommend painting when the render is beyond restoration.

Yes—monocouche, K-rend, Weber, lime render, pebbledash, and traditional sand-cement. Each substrate requires tailored chemistry and dwell times. We assess your specific render type and adjust the protocol accordingly.

Yes, provided the paint is sound and well-adhered. Our pH-neutral biocides won't strip or discolour quality masonry paint. If the paint is failing, cleaning may expose underlying issues that need addressing.

We can apply breathable water-repellent treatments post-clean to reduce future organic growth and moisture ingress. These are optional and discussed during the assessment phase.

We mask sensitive areas, pre-wet plants, and use controlled application to prevent overspray. All biocides are rinsed thoroughly, and we inspect surrounding areas before and after treatment.

Pre-clean assessment, low-pressure pre-rinse, biocide application, controlled dwell time, neutralisation rinse, post-clean inspection, and waste water management. Full RAMS and COSHH documentation provided for commercial sites.

Yes. We work with conservation officers and follow SPAB/Historic England guidelines. Our low-impact, chemistry-led approach is ideal for sensitive substrates where mechanical cleaning is prohibited.

Yes. Efflorescence requires acid-based treatment to dissolve mineral salts. We assess the cause (rising damp, poor detailing) and recommend remedial action if the issue is structural.

Pricing depends on surface area, contamination level, access requirements, and substrate type. Most residential projects range from £500–£2,500. We provide fixed-price quotes with no hidden fees.

We use water-fed poles, MEWPS, and rope access depending on height and access. Scaffolding is rarely required unless specified by the client for other works.

Yes, provided temperatures remain above 5°C and no frost is forecast within 48 hours. Biocide efficacy and dwell times are temperature-dependent, so we adjust protocols seasonally.

Biological staining (algae, lichen) is fully removable. Rust, tannin, and some industrial stains may require additional treatments. We assess stain type during the survey and set realistic expectations.

Yes. We photograph all elevations pre- and post-clean and provide a completion report. Commercial clients receive detailed records for asset management and compliance purposes.

Most residential properties are completed in 1–2 days. Larger commercial buildings may require 3–5 days depending on size, access, and contamination severity.

Not necessarily. We require water and electrical access, but once set up, we can work independently. We'll notify you before arrival and upon completion.

Light rain won't affect results once the biocide has dwelled. Heavy rain during application may require rescheduling. We monitor forecasts and plan accordingly.

We guarantee workmanship and process adherence. Results longevity depends on environmental factors beyond our control, but we offer maintenance contracts to sustain long-term performance.

Moss, algae, and lichen retain moisture, accelerate tile degradation, block drainage, and add weight to the roof structure. Regular cleaning extends roof lifespan, improves water runoff, and maintains property value.

Not when done correctly. High-pressure washing can break tiles and strip protective coatings. Our low-pressure biocide method kills organic growth at the root without mechanical stress, preserving tile integrity.

Concrete tiles, clay tiles, slate, felt, fibreglass, and metal roofing. Each material requires specific chemistry and application techniques. We assess your roof type and tailor the process accordingly.

Both. We manually remove heavy moss build-up to reduce load, then apply biocide to kill remaining spores and prevent regrowth. This two-stage approach delivers immediate and long-term results.

Typically 3–5 years depending on roof orientation, tree coverage, and local climate. North-facing roofs and properties near trees may require more frequent treatment.

Yes. We offer combined roof and gutter cleaning packages. Clean gutters improve drainage and prevent overflow that can stain facades and cause damp issues.

Yes. We pre-wet plants, control runoff, and use biodegradable biocides where possible. All waste water is managed to prevent contamination of soil and waterways.

We can apply breathable roof coatings post-clean to enhance weather resistance and reduce future organic growth. These are optional and discussed during the assessment.

We use ladder systems, roof ladders, harnesses, and edge protection in line with Working at Height Regulations. All operatives are trained and insured for roof work.

Yes. We conduct a visual inspection pre-clean and report any broken tiles, flashing issues, or structural concerns. We're not roofers, but we'll flag issues that need specialist attention.

No. Cleaning removes organic growth but doesn't repair structural defects. If leaks are present, we recommend a roofing contractor to address the underlying issue before cleaning.

Pricing depends on roof size, pitch, contamination level, and access difficulty. Most residential roofs range from £400–£1,500. We provide fixed-price quotes after a site survey.

Yes. Flat roofs (felt, fibreglass, EPDM) accumulate moss and algae in low-drainage areas. We clean and treat these surfaces to prevent ponding and extend membrane lifespan.

Yes, provided conditions are safe (no ice, high winds, or heavy rain). Biocide performance is temperature-dependent, so we adjust formulations and dwell times for cold-weather application.

Yes. Removing moss and algae restores the original tile colour and improves kerb appeal. Results are most dramatic on heavily contaminated roofs.

We remove all accessible moss and debris. Some residual material may remain in hard-to-reach areas (under ridge tiles, in valleys), but biocide treatment prevents regrowth.

Most residential roofs are completed in 1 day. Larger or heavily contaminated roofs may require 2 days. We'll confirm timings during the survey.

Not necessarily. We require water and electrical access, but once set up, we can work independently. We'll notify you before arrival and upon completion.

We collect and remove all moss and debris from site. Waste is disposed of in accordance with environmental regulations.

We guarantee workmanship and process adherence. Results longevity depends on environmental factors, but we offer maintenance contracts to sustain long-term performance.

Algae, moss, and organic growth create slip hazards, degrade jointing, and stain surfaces. Regular cleaning improves safety, extends surface lifespan, and maintains property appearance.

High-pressure washing (>150 bar) can erode jointing, etch soft stone, and create surface pitting. Our controlled-pressure approach (80–120 bar) cleans effectively without substrate damage.

Block paving, natural stone, concrete, porcelain, resin-bound, tarmac, and pattern-imprinted concrete. Each material requires specific pressure settings and cleaning agents.

Yes. We remove contaminated sand during cleaning and re-sand joints with kiln-dried jointing sand to stabilise the surface and prevent weed growth.

Yes. Oil stains require degreasing agents and hot water treatment. Results depend on stain age and substrate porosity. We assess during the survey and set realistic expectations.

Typically 2–4 years depending on usage, tree coverage, and drainage. Sealing post-clean can extend results and make future cleaning easier.

Yes. We apply breathable sealants to block paving, natural stone, and concrete to enhance colour, reduce staining, and inhibit weed growth. Sealing is optional and discussed during the assessment.

Pressure washing removes surface weeds, but roots may remain. We can apply residual weed treatment post-clean to prevent regrowth for 6–12 months.

Yes. Pattern-imprinted concrete requires low-pressure cleaning to avoid damaging the surface texture and sealant. We use pH-neutral detergents and controlled pressure to clean safely.

We contain and recover waste water where possible, disposing of it in accordance with environmental regulations. We prevent runoff into drains, watercourses, and neighbouring properties.

We can work around vehicles, but results are best when the area is fully accessible. We'll discuss access requirements during the survey.

Pricing depends on surface area, contamination level, surface type, and access. Most residential driveways range from £150–£600. We provide fixed-price quotes after a site survey.

Yes. We clean car parks, loading bays, and external hard standings for commercial clients. We work out-of-hours to minimise disruption and provide RAMS/COSHH documentation.

Cleaning removes surface contamination and restores some colour. Sealing enhances colour depth and provides a 'wet look' finish. Severely faded paving may require re-colouring treatments.

We pre-wet plants, control overspray, and use biodegradable detergents where possible. Waste water is managed to prevent contamination of soil and landscaping.

Most residential driveways are completed in 2–4 hours. Larger or heavily contaminated areas may require a full day. We'll confirm timings during the survey.

Yes, once dry (typically 2–4 hours). If sealing is applied, we recommend avoiding traffic for 24–48 hours to allow full curing.

Yes, provided temperatures remain above 5°C and no frost is forecast. Sealing is not recommended in cold or wet conditions, so we may defer that stage until spring.

Yes. Chewing gum requires heat treatment or chemical dissolution. Paint removal depends on type and age—we assess during the survey and recommend the best approach.

We guarantee workmanship and process adherence. Results longevity depends on usage and environmental factors, but we offer maintenance contracts to sustain long-term performance.

Algae, moss, and mould make timber slippery, accelerate rot, and degrade protective treatments. Regular cleaning extends timber lifespan, improves safety, and maintains appearance.

Yes, if done incorrectly. High pressure (>80 bar) can raise grain, splinter softwood, and strip protective coatings. Our low-pressure biocide method cleans safely without mechanical damage.

Softwood, hardwood, composite decking, and treated timber. Each material requires specific pressure settings and cleaning agents to avoid damage.

Yes. We apply UV-protective stains, oils, and preservatives post-clean to enhance colour, repel water, and extend timber lifespan. Treatment options are discussed during the assessment.

Yes. Composite decking requires low-pressure cleaning and pH-neutral detergents to avoid surface damage. We tailor the process to the specific composite material.

Typically 2–3 years depending on exposure, orientation, and protective treatment. Oiling or staining post-clean extends results and improves weather resistance.

Yes. Our biocide treatment kills organic growth at the root and prevents regrowth for 2–3 years. Surface cleaning removes visible contamination immediately.

Yes. We use oxalic acid-based treatments to neutralise UV damage and restore the original timber colour. Results are most effective on recently weathered timber.

We don't offer carpentry services, but we'll flag any structural issues (rot, loose boards, broken posts) during the assessment and recommend specialist contractors if needed.

We pre-wet plants, control overspray, and use biodegradable biocides where possible. All waste water is managed to prevent contamination of soil and landscaping.

Yes, provided the coating is sound. Cleaning may expose areas where paint or stain has failed. We assess coating condition during the survey and recommend re-treatment if necessary.

Pricing depends on surface area, contamination level, timber type, and treatment requirements. Most residential projects range from £200–£800. We provide fixed-price quotes after a site survey.

Most residential projects are completed in 1 day. Larger areas or multi-stage treatments (clean, restore, oil) may require 2 days. We'll confirm timings during the survey.

Yes, once dry (typically 4–6 hours). If oiling or staining is applied, we recommend avoiding traffic for 24–48 hours to allow full absorption and curing.

Yes, provided temperatures remain above 5°C and no heavy rain is forecast. Oiling and staining are not recommended in cold or wet conditions, so we may defer that stage until spring.

Yes. Removing algae and moss significantly improves grip. We can also apply anti-slip treatments post-clean for additional safety.

Yes. Timber cladding requires low-pressure cleaning and controlled application to avoid water ingress behind the cladding. We assess fixing details and adjust the process accordingly.

Tannin staining (dark streaks from knots) is difficult to remove fully but can be lightened with oxalic acid treatment. We assess during the survey and set realistic expectations.

Light rain won't affect biocide efficacy once dwelled. Heavy rain during oiling or staining may require rescheduling. We monitor forecasts and plan accordingly.

We guarantee workmanship and process adherence. Results longevity depends on environmental factors and protective treatment, but we offer maintenance contracts to sustain long-term performance.

Dust, pollen, bird deposits, and atmospheric pollutants create an insulating layer that blocks photon absorption and reduces energy yield by up to 25%. Regular cleaning restores peak efficiency.

Yes. High pressure can force water past panel seals, damage anti-reflective coatings, and void manufacturer warranties. Our sub-40 bar process cleans safely without mechanical stress.

Most UK installations benefit from biannual cleaning—spring and autumn—to counter pollen season and leaf fall. High-pollution or coastal sites may require quarterly service.

Yes. We document baseline efficiency pre-clean and verify performance post-clean. Most clients see 10–25% yield improvement depending on contamination severity.

We use deionised water and soft-bristle brushes at low pressure (<40 bar) to remove contaminants without scratching or stressing panel seals. No harsh chemicals, just pure water and mechanical agitation.

Deionised water contains no minerals, so it dries spot-free without leaving residue that can attract dust and reduce light transmission. It's the industry standard for panel cleaning.

Yes. We clean commercial solar arrays using rope access, MEWPS, or water-fed poles depending on height and access. We provide RAMS/COSHH documentation and work out-of-hours to minimise disruption.

Yes. Solar thermal panels accumulate the same contaminants as PV panels and benefit from the same cleaning process.

No, provided cleaning is done correctly. Our low-pressure, manufacturer-approved method complies with warranty terms. High-pressure washing or abrasive cleaning can void warranties.

Yes, provided temperatures remain above 0°C and no ice is present. We avoid cleaning in freezing conditions to prevent thermal shock and ice formation on panels.

We use ladder systems, roof ladders, harnesses, and edge protection in line with Working at Height Regulations. All operatives are trained and insured for roof work.

Yes. We conduct a visual inspection pre-clean and report any cracks, delamination, or wiring issues. We're not electricians, but we'll flag concerns that need specialist attention.

Pricing depends on panel quantity, access difficulty, and contamination level. Most residential installations range from £150–£400. We provide fixed-price quotes after a site survey.

Most residential installations are completed in 1–2 hours. Larger commercial arrays may require a full day. We'll confirm timings during the survey.

Yes. Ground-mounted panels are easier to access and clean. We use the same low-pressure, deionised water method to ensure safe, effective cleaning.

No. Rain removes loose dust but doesn't dissolve bird deposits, pollen, or atmospheric pollutants. These contaminants require mechanical agitation and pure water rinsing to remove fully.

Yes. We provide scheduled cleaning contracts with fixed pricing and performance tracking. Contracts include biannual or quarterly visits depending on site requirements.

Yes. We work around bird deterrents and guards. If netting obstructs access, we'll discuss removal and reinstallation with you or your installer.

We carry full public and professional indemnity insurance. In the unlikely event of damage, we'll repair or replace affected panels at no cost to you.

We guarantee workmanship and process adherence. Efficiency improvement depends on contamination level and panel condition, but we document results and provide performance data.
