A damp patch alone does not identify the cause; rainwater, pipework or junction details may be involved. We review the description and photos, then determine what needs a visit or inspection before proposing waterproofing and repair work.
Understand the cause first
Explain when damp appears, whether it relates to rain or use, and its position relative to roofs, bathrooms and utilities. Painting over it without identifying the source may hide the effect temporarily while leaving the cause.
A system suited to the details
Define surface preparation, junction treatment, falls, protection and waterproofing system according to site condition, project specifications and product instructions. No single product suits every surface or use.
Testing and warranty terms
Set out inspection, handover and the scope of any written warranty included, including exclusions for other parties’ work or misuse. A general promise of a warranty period is insufficient without a document defining its scope and terms.
Prepare these details for a quote
- Photos of the issue and the associated roof or space.
- When it appeared and any previous repairs.
- Approximate area, finish type and access conditions.
Can a photo determine the final repair?
A photo helps with an initial understanding but may not identify the source or substrate condition. A visit and tests may be needed before agreeing on the solution.
