Render Cleaning across the Scottish Borders and Edinburgh
Render can become marked by algae, traffic film, moss, and weathering, especially on shaded or exposed elevations. Green or black staining on a rendered wall makes a property look older and less well maintained than it is. Render cleaning should not be treated like a standard hard-surface wash. The surface type, condition, and existing coating all matter, so the recommended method should be chosen carefully before any work begins.
Rendered walls are one of the most visible parts of a property exterior. Staining from algae and atmospheric pollution accumulates gradually, and homeowners often do not notice how much the appearance has degraded until the wall is cleaned. Different render types respond differently to cleaning. K Rend, monocouche, roughcast, and traditional sand-and-cement renders each have specific characteristics that influence the right cleaning method. Using the wrong approach can damage the surface, strip coatings, or force water behind the render.
What affects render cleaning costs?
We do not publish generic prices because every property is different. The cost of render cleaning depends on several factors that we assess during your free property visit. Here is what influences your quote.
Size and scope
The larger the area requiring render cleaning, the longer the work takes and the more it costs. We measure accurately during the assessment.
Access and height
Properties with difficult access, steep pitches, or height restrictions may require additional equipment or time, which affects the price.
Surface condition
The level of moss, algae, staining, or damage affects how much work is needed. Heavily soiled surfaces take longer to clean properly.
Method required
Different surfaces need different cleaning methods. Soft washing, biocide treatment, and controlled pressure each have different cost profiles.

Common questions
Render Cleaning questions answered
Some rendered surfaces can be damaged by high-pressure washing, particularly K Rend and thin-coat systems. The render type and condition should be assessed before a cleaning approach is chosen. We use soft washing or controlled low-pressure methods for most render types.
Algae and organic growth commonly appear where moisture, shade, and weather exposure create the right conditions. North-facing walls and areas near trees or hedges are most affected.
A typical house with rendered walls takes one day. The biocide treatment may need a few weeks to fully take effect, during which remaining staining gradually fades.
We assess the condition of any existing coatings before cleaning. If the paint or finish is in poor condition, we will flag this before starting rather than discovering it during the clean.
