Biocides must be products authorised for the purpose and used as the label says, wash water and chemicals should be kept out of surface water drains and watercourses, active birds' nests and bat roosts must not be disturbed, and scaffolding or towers on a public pavement usually need a council licence.RegulationsFri, 06 Nov 2026 09:00:00 +0000https://render-cleaning.pages.dev/blog/best-time-of-year-to-clean-render-uk/https://render-cleaning.pages.dev/blog/best-time-of-year-to-clean-render-uk/Spring, from about March to May, and early autumn, from September to October, are usually the best times to clean render in the UK. Biocide treatments work best on dry days above around 5°C with no rain forecast for at least several hours, and these seasons avoid the frost of winter and the fast drying of hot summer days.SeasonalFri, 06 Nov 2026 09:00:00 +0000https://render-cleaning.pages.dev/blog/how-render-is-reached-at-height-scaffold-towers-poles/https://render-cleaning.pages.dev/blog/how-render-is-reached-at-height-scaffold-towers-poles/Most two-storey rendered houses can be cleaned from the ground using telescopic water-fed poles and low pressure spray equipment. Towers, cherry pickers or scaffolding are used for taller buildings, hard-to-reach elevations, or when the render also needs repairs or hands-on cleaning. Access is often the biggest single factor in the price of a job.How-toFri, 06 Nov 2026 09:00:00 +0000https://render-cleaning.pages.dev/blog/diy-render-cleaning-mistakes/https://render-cleaning.pages.dev/blog/diy-render-cleaning-mistakes/The most damaging DIY render cleaning mistakes are using a high pressure jet washer, using undiluted bleach or acid cleaners, scrubbing coloured or textured finishes, cleaning in the wrong weather, and ignoring what type of render it is. Many problems come from treating render like a patio, when it needs gentle, low pressure methods.AdviceFri, 06 Nov 2026 09:00:00 +0000https://render-cleaning.pages.dev/blog/render-cleaning-blocks-of-flats-managing-agents/https://render-cleaning.pages.dev/blog/render-cleaning-blocks-of-flats-managing-agents/For blocks of flats, render cleaning is usually planned as part of a cyclical maintenance programme. If any leaseholder's share of the cost will exceed £250, the landlord in England and Wales must carry out Section 20 consultation before the work. Access equipment, resident notices, protection of cars and balconies, and the building's insurance and safety documents also need planning.BusinessFri, 06 Nov 2026 09:00:00 +0000https://render-cleaning.pages.dev/blog/cleaning-render-before-selling-house/https://render-cleaning.pages.dev/blog/cleaning-render-before-selling-house/Cleaning green or black stained render before selling is often worth it, because it typically costs a few hundred pounds for a terraced or semi-detached house and makes a big difference to listing photos and first impressions. It will not hide defects from a surveyor, so cracks, blown patches or damp should be dealt with or disclosed separately.HomeownersFri, 06 Nov 2026 09:00:00 +0000https://render-cleaning.pages.dev/blog/stained-render-on-new-build-house/https://render-cleaning.pages.dev/blog/stained-render-on-new-build-house/New build render can stain within a year or two because of algae on shaded walls, poor drip details under sills, run-off from copings and white efflorescence or lime bloom on monocouche. If the house is within the builder's warranty period, usually the first two years, report defects to the builder first before paying for cleaning yourself.HomeownersFri, 06 Nov 2026 09:00:00 +0000https://render-cleaning.pages.dev/blog/render-cleaning-coastal-rural-and-wooded-homes/https://render-cleaning.pages.dev/blog/render-cleaning-coastal-rural-and-wooded-homes/Render on coastal, rural and tree-lined homes usually stains faster than in town centres. Damp sea air, salt, shade from trees, airborne nutrients from farmland and wind-driven rain all feed algae and lichen. These homes often benefit from more frequent gentle cleaning and a protective treatment to slow regrowth.AdviceFri, 06 Nov 2026 09:00:00 +0000https://render-cleaning.pages.dev/blog/render-cleaning-myths/https://render-cleaning.pages.dev/blog/render-cleaning-myths/Many common beliefs about render cleaning are wrong. Pressure washing is not the best way to clean render, silicone render is not maintenance free, bleach is not a safe all-purpose cleaner, and clean-looking render can still have algae spores in it. Gentle soft washing with a suitable biocide is usually safer and longer lasting.AdviceFri, 06 Nov 2026 09:00:00 +0000https://render-cleaning.pages.dev/blog/ways-to-save-money-on-render-cleaning/https://render-cleaning.pages.dev/blog/ways-to-save-money-on-render-cleaning/The best ways to save on render cleaning are to fix the causes of staining such as leaking gutters, clean before growth becomes heavy, book with neighbours on the same street, share scaffold or access with other planned work, and only clean the walls that need it. A protective treatment can cost a little more now but extend the time before the next clean.CostsFri, 06 Nov 2026 09:00:00 +0000
