New rendering or repairs to existing render
New masonry, a worn finish and damaged existing render need different scopes. Decide whether you are choosing a finish for a suitable wall or investigating a problem with the current surface. The background and any continuing cause of damage should shape the work before appearance is settled.
Render systems and surface finishes
Sand and cement, monocouche and silicone finishes offer different material routes and system build-ups. Colour and texture are part of the decision, but compatibility with the wall comes first. Ask what preparation and supporting layers are required rather than comparing only the visible final coat.
Assess the existing render condition
Cracks, missing areas and detachment do not all call for complete replacement. Local repair may be appropriate where the surrounding system is suitable. Widespread deterioration can lead to a re-rendering discussion. An assessment should establish which material can remain and what needs attention beneath it.
Plan openings, edges and exterior access
Consider the whole elevation, including windows, doors, edges and attached pipes or fittings. Access may vary between front, side and rear walls. Include neighbouring boundaries and protected surfaces in the discussion so the practical scope reflects the actual property.
Define the full rendering scope
Provide photographs of each affected elevation, approximate dimensions and any previous render history. Agree preparation, access, waste handling and the selected finish. External work also depends on suitable conditions for the specified system, so scheduling should allow for the actual weather and product requirements.
PRACTICAL SERVICE DETAILS
Common questions
Can existing render be repaired rather than replaced?
Sometimes. The render, its bond and the underlying cause of damage need assessment to decide whether local repair is appropriate.
How is a render finish chosen?
The wall construction, existing surface, exposure and desired appearance all matter. Compare complete suitable systems rather than colour alone.
Can only one elevation be treated?
It may be possible, but junctions and appearance alongside retained elevations need consideration. State clearly which faces of the building are included.
What affects access and timing?
Height, obstacles, boundaries, protection and suitable weather conditions can all affect the work. Include these when discussing the scope and programme.
