Identify changes in the existing render
Look at what has changed: a line in the surface, a missing patch, visible detachment or deterioration across an elevation. Describe the symptoms without assuming their cause. Take photographs from a safe position and avoid disturbing material that may be loose overhead.
Crack repairs, patching or full renewal
Crack repairs address cracking in otherwise present render. Patching reinstates local missing or unsuitable areas. Full re-rendering deals with a broader renewal scope when retaining the existing surface is not appropriate or a complete replacement is planned. More than one route may need discussing initially.
Assess why the render has deteriorated
The render system, its background and moisture or movement history affect the decision. A cosmetic repair does not necessarily resolve the original cause. Include previous attempts to repair the area and any work around windows, pipes or roof edges that coincided with the damage.
Balance retained areas and the new finish
Retaining suitable material can limit the intervention, but appearance matters too. A patch may differ from weathered render or old paint. Discuss the likely boundary between repair and decoration, and whether a consistent elevation finish is an important part of the outcome.
Plan exterior access and finishing
Provide an elevation list with approximate areas, heights and access restrictions. If replacement is needed, compare suitable finishes only after the background is understood. Ask the quote to separate assessment-dependent repairs, preparation, access and the final appearance you want.
PRACTICAL SERVICE DETAILS
Common questions
How is repairability assessed?
The condition of the render, its attachment and the background all matter. The cause and extent need consideration before choosing local work or renewal.
Can sound render be retained?
Retention may be possible where it is suitable for the repair or system. It should follow assessment rather than an assumption that all old material must go.
Will a patch remain visible?
It can be, because colour, texture and weathering vary. Wider decoration or finishing may be part of the appearance discussion.
Is loose render a different job from a hairline crack?
Yes. Detachment and missing material raise different preparation and reinstatement questions from a crack in otherwise present render. Explain all visible symptoms.
