There is a meaningful difference between growth sitting on a rendered surface and growth living within it, and it explains why some walls clean up in a single visit while others need considerably more. Render is porous to some degree whatever the system. Traditional sand and cement is openly absorbent; even modern thin-coat finishes have texture, micro-voids and the fine grooves left by a scraped or floated finish. Algae colonise all of that, not merely the outer face. Spores settle into recesses, germinate where moisture collects and establish below the level anything superficial will ever reach. A wall rinsed with water removes what sits on top and leaves everything embedded, which is why growth returns within a season. The visible green disappears and the colony survives intact. Biocidal treatment works differently because it is a liquid that wicks into the surface rather than a force applied to it. Applied generously and given time, solution travels into the texture, reaches the material lodged in the pores and kills it there. That is why dwell matters more than anything else in the method, and why absorbent render is deliberately re-wetted part way through: the chemistry has to get where the growth actually is. Lichen adds another dimension, since its rhizines physically penetrate the coating to anchor it, meaning part of the organism is genuinely inside the render rather than resting on it. Properties in Coates are treated with coverage and dwell set to how deep the surface actually is, rather than to how the wall happens to look from the pavement.
Method statements are usually associated with commercial contracts, and they are produced here for domestic work as well. It is not a formality. Writing down what will be done forces the decisions to be made before the crew arrives rather than on the morning. The document records the render system identified, the dilution approach, the intended dwell, the sequence of elevations, what protection is required and where, whether access equipment is needed and how it will be positioned, where run-off will travel and what has to be covered as a result, and the wind and temperature limits beyond which work stops. That means a crew arriving already knows the plan, and it means the plan was made by somebody who had looked at the building properly. It also gives the customer something concrete. Pro Clean Xtreme provides the method statement alongside the quotation on request, together with COSHH data sheets for the products involved and public liability certification. A homeowner comparing contractors can then judge on what will actually be done rather than on a figure and an assurance. And it protects everybody if something is queried afterwards. What was agreed, what was protected and what limits applied are all recorded rather than remembered differently by two parties. The effort involved is modest, since most of the thinking has to happen anyway. What changes is whether it is written down. Householders in Coates therefore receive a free survey, a written and fixed quotation naming each elevation, a documented method on request, no deposit, and payment only once the work has been completed and inspected with them.
Area is the obvious driver of a render cleaning price and it is not the only one, which is easiest to show by comparison. Take two houses each with 130 square metres of rendered wall. The first is a modern detached property in silicone render, two storeys throughout, with clear access on all four sides, hard standing for the vehicle, light green algae and a lawn to each elevation. Protection takes forty minutes, solution sits on the surface and works efficiently, one pass covers the wall, and the day finishes comfortably. It prices at the lower end of the £550 to £880 band. The second has the same area in absorbent sand and cement, three storeys at the gable, a conservatory against the rear elevation, mature borders along two sides, a side passage a metre wide, and mature lichen across the shaded faces. Protection takes over two hours. The render drinks solution and needs re-wetting to hold dwell. The gable requires a tower. A second application will be needed in six weeks. It is quoted individually rather than within any band at all. Same square metres, entirely different jobs, and the difference between the two figures is work rather than margin. A rate applied blindly to area would misprice both of them. That is why the rate of £4 to £8 per square metre is a range rather than a figure, and why a survey rather than a measurement produces the price. Properties in Coates are assessed for system, severity, access and complexity alongside area, and the fixed written figure reflects all four together.
Remove years of dirt, grime, algae and staining for a cleaner, fresher finish.
Professional techniques designed to protect your surfaces while delivering outstanding results.
Keep your property looking its best with regular render cleaning.
Keep your property looking clean, fresh and well maintained with professional render cleaning in Coates.

Our professional render cleaning service is designed to safely restore the appearance of rendered surfaces without causing unnecessary damage.
Printing, signage and packaging premises combine light industrial operations with customer-facing frontages, and render cleaning there has to serve both. The buildings typically comprise a production hall, finishing and storage areas, a trade counter or reception, offices and a yard for deliveries and collections. Rendered elevations facing that yard collect vehicle-related soiling alongside ordinary organic growth, while the frontage carries the presentational weight for a business whose customers judge production quality by what they can see of the premises. Production considerations shape the programme. Extraction and ventilation serving press halls, finishing lines and drying areas are identified and isolated before application, since these operations frequently run continuously and cannot tolerate anything drawn in from outside. Paper, board and substrate stored near external doors is moved or sheeted, and shutters stay closed while adjoining elevations are treated. Timing usually works best outside production shifts, and many of these businesses run extended or overnight hours, so an early Saturday or a planned shutdown often suits better than a weekday. Protection covers signage and display work, which on a signage business is frequently the shopfront itself, along with glazing, lighting, cameras, waste and recycling compounds and anything awaiting collection. Documentation is issued with every quotation: site-specific risk assessments, method statements, COSHH data sheets and public liability certification, all of which many of these businesses retain for their own audit records. Owners and site managers responsible for premises in Coates can arrange a survey covering every rendered elevation, receive a written specification and fixed price, and agree a phased programme built around production and delivery schedules.
