Damp and Mould Specialist Lewisham

A commissioning sheet, plumbing note and decorating invoice answer different questions. Check which component was tested, the date and any recorded access limit. A test of one accessible fitting should not be treated as a check of every concealed connection. If documents use unfamiliar terms, retain them for the relevant contractor instead of interpreting them as a whole-room guarantee.

An assessment of the newly installed en-suite can compare accessible seals, fittings and repeated wetting with that history. Describe panels designed to open and who can provide suitable access. The next check should identify an unresolved connection or wall area, keeping the reason for disturbance clear before finishes are removed.

Photograph the bedroom side and the corresponding bathroom position. Note whether wetting follows shower use, drainage or a period with no bathing. Record the normal extractor controls and any settings changed at handover. A tiled face can hide a different condition from the painted bedroom side, so the two views should remain distinct in the findings.

A review of post-installation moisture at the shared wall compares accessible readings with the actual materials. Installation photographs may help locate pipe routes but cannot confirm their present condition. Ask which part of the existing evidence supports the next enquiry and which current view is still missing.

Where the concern is repeated surface wetting after bathing, checking the handed-over extraction arrangement can help relate the available controls to the symptoms. Keep this separate from a suspected fitting leak. Before another contractor makes good the bedroom, provide the record of what was installed, what was tested and what the moisture assessment still needs to establish.

Treatment of the bedroom mould should reflect the material condition and accessible extent. If the en-suite is repeatedly supplying moisture, that needs its own response alongside treatment. A plumbing repair and a ventilation change have different purposes, even if both are recommended.

Before reinstating finishes, check areas concealed by fitted furniture or bathroom panels. A clean exposed bedroom wall cannot establish the condition of the shared backing. Keep the original photographs and record the source work completed, so a later review can compare those exact bedroom and bathroom positions.

When calling, describe both spaces and explain which marks appeared first. Mention if the wall is shared with another flat or if access to fittings is limited. You do not need to diagnose the issue yourself. A clear timeline and simple room plan help define a useful scope before anyone disturbs the bathroom installation.

If earlier cleaning temporarily removed the bedroom growth, note how soon the surrounding surface became wet again and whether the en-suite arrangement changed. That record helps distinguish a recurring condition from a separate event, without inventing a precise cause from the recurrence alone.
