Social tenants

18.4% of Plymouth households rent from the council or a housing association. Report damp and mould to your landlord. They must investigate significant hazards within 10 working days and give you a written summary of their findings within three working days of the inspection. Emergency hazards must be made safe within 24 hours.

Private tenants

22.6% of Plymouth households rent privately, many in older terraces and converted flats. Report mould to your landlord in writing, with dated photos, and keep copies. If nothing happens, Plymouth City Council can inspect private rented homes and require repairs.

Landlords should look for the cause, not just repaint. A blocked gutter, failed pointing or a broken extractor fan is cheaper to fix than repeated redecoration.

Finding the cause

A good survey checks gutters, pointing, render and ground levels, and measures humidity and surface temperatures inside. Condensation is the most common cause and is fixed by heating, ventilation and insulation.

Be wary of a quote for injected damp-proofing based only on a moisture meter reading. Meters often over-read on old plaster, and the real cause is frequently outside the wall or in the way the room is used.

Cleaning it off and keeping it away

For small patches, wear gloves and a mask and use a mould remover; our guide to removing mould from walls explains how. For larger areas, or if anyone in the home has asthma or a weak immune system, get a specialist in.

Long term, steady background heating, extractor fans that run and furniture kept off cold outside walls stop most condensation mould coming back.

Plymouth homes and what they need

Interwar and postwar semis

Black spots behind wardrobes and in bedroom corners are usually condensation on cold external walls. Check whether the cavity walls were ever insulated, and whether the insulation has bridged or got wet.

Victorian terraces on the hills

Solid walls facing the prevailing weather soak up rain. Check gutters, downpipes, pointing and render before treating inside, and use breathable lime-based materials when replastering.

Waterfront and city-centre flats

Mould in airtight flats is usually down to moisture with nowhere to go. Drying washing indoors without ventilation is a common cause, so use the extractor or a dehumidifier.

Areas covered

Engineers who cover Plymouth work across areas including Plympton, Plymstock, Mutley, Mannamead, Peverell, Stoke, Devonport, Stonehouse, Hartley and Saltash.

Questions people in Plymouth ask

Does Awaab's Law cover private tenants in Plymouth?

Not yet. The current rules apply to council and housing association homes. Private tenants should go to the landlord and then to Plymouth City Council.

Can the Warm Homes: Local Grant help with mould?

It funds insulation and heating improvements for eligible privately owned homes, which can cut condensation. It doesn't pay for repairs such as gutters or roofs.
