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.
Find out what is causing the moisture before paying for a treatment. Mayfair arranges investigation of damp, condensation and water ingress across London, then helps coordinate the agreed source repairs and making good.

Find the right repair in Southwark
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.

Damp & mould investigation in Southwark
Planning the repair at your Southwark property
For a Bermondsey or Dulwich enquiry, explain whether the work is confined to your home or also involves another dwelling. On a managed building, the contact for shared services or fabric may be needed.
A damp patch crossing a property boundary
Include reports from the room above or adjoining home, the dates of visible changes and any earlier investigations. The source may need access outside your own rooms. We scope the investigation before recommending a treatment.
Room conditions and building defects need separating
For damp in a managed flat, include the location of the patch, any leaks reported by neighbours and ventilation faults. Shared façades, roofs and services may require the building team; an internal surface treatment alone may not address the source.
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.

Help us prepare the right visit
Include the affected rooms, building contact and reports from other occupiers. Keep the source investigation and finishing work distinct in the brief.
Can you tell whether the damp is from my neighbour?
Not from the patch alone. Inspection, symptom history and sometimes coordinated access are needed to distinguish water ingress, a leak and other moisture mechanisms.
Should I ask the building manager before booking a damp visit?
Report suspected defects in shared fabric or services to them and retain the reference. Mayfair can discuss the internal symptoms and investigation scope using that information, without assuming the cause is within your flat.

About neighbourhoods and postcode matching
August 2026 ONS postcode data identifies boroughs sharing an outward district. Named centres use London Plan references; neighbourhood postcode examples use local address sources. Neither defines an exact neighbourhood boundary. Even a full postcode entered here is matched only by its first part.
Where a dedicated local service guide is available, we link to it. Other places lead to the relevant borough guide with your selected area carried into the enquiry. Your full repair address is needed when arranging attendance.

These are borough-wide postcode associations. A district can cross boroughs and include other neighbourhoods or addresses outside London. Even a full postcode shown in the finder gives district suggestions, not an address check. Give the street address and full postcode when booking.

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.
Do you cover Southwark?
