Find the right repair in East London
You do not need to know the technical name. Choose the description that fits, then see the repair options and what to include in your enquiry.
Is my damp wall caused by condensation or a leak?
Appearance alone cannot establish the cause. Tell us whether the patch follows rain, use of plumbing or cold weather, and whether it changes size. Mayfair can arrange the appropriate investigation; a moisture reading by itself is not a complete diagnosis.
Mould keeps coming back. Will repainting fix it?
Repainting does not resolve the source of recurring moisture. Describe the affected rooms, ventilation and any signs of leaks. Investigation should establish the cause and suitable remedial scope before decorating is arranged.
Is a damp patch near the skirting definitely rising damp?
No. Low-level staining or damaged plaster is a symptom, not proof of rising damp. Leaks, external moisture and other causes need consideration. Request an investigation before committing to injection treatment, replastering or waterproofing.

Example work, explained
Finding the cause of a damp wall
- The problem
- A damp patch, peeling finish or recurring staining needs a cause established. A meter reading or photograph alone cannot distinguish every source of moisture.
- The work involved
- Review when the patch appears, nearby plumbing, external defects, ventilation and the building's construction. Agree further investigation and source repairs from the findings.
- Checks and next steps
- Explain the likely source, any limits of the inspection and the plan for repair and drying. Surface treatment or redecorating is considered once the underlying problem is addressed.

Questions about damp & mould investigation
Can you tell the cause of damp from a photograph?
Photos help describe the symptoms but do not prove the cause. Building condition, moisture sources and the history of the problem need consideration before a treatment is recommended.
How much does damp & mould investigation cost?
Investigation is quoted to scope. Specialist surveys, laboratory testing, waterproofing systems and reinstatement are separate unless expressly included. A visual inspection is not a structural or mortgage survey. We provide a quote including VAT for the agreed work.
