Damp and Mould Removal Norwich: Specialists

Your next step depends on who owns your home. Almost a third of Norwich households rent from a social landlord, most of them from the city council, and since October 2025 those landlords must meet legal deadlines for dealing with damp and mould.

If you own your home or rent privately, the job is the same: find the cause before treating the mould.

Council and housing association tenants

Under Awaab's Law, social landlords must investigate a significant damp or mould hazard within 10 working days of it being reported. For emergency hazards in Norwich, the landlord has 24 hours to act. After the investigation you should get a written summary of what was found.

Report it in writing, with photos and dates, through your landlord's repairs service. You don't need to pay a private specialist.

Private renters

26.9% of Norwich households rent privately. Your landlord must keep the home free of serious hazards, and damp and mould is one of them. Report it in writing. Norwich City Council's private sector housing officers can step in where a landlord ignores you.

Finding the cause

Most black mould on walls and window reveals is condensation. A survey should also rule out leaking gutters, failed pointing, bridged damp proof courses and plumbing leaks, which need building repairs rather than fans.

Ask the surveyor to take moisture readings and explain them. Be wary of anyone who diagnoses rising damp and quotes for injection without looking at the outside first.

Clean-up

Small patches can be cleaned with a mould spray and dried thoroughly. Our guides on removing mould from walls and window condensation explain the steps. Big areas, or mould in a home with a baby or someone with lung problems, need professional help.

Norwich homes and what they need

Interwar and postwar semis

Cold corners in bedrooms behind wardrobes are a classic spot. Moving furniture off outside walls and better heating usually help.

Victorian terraces inside the ring road

Solid walls and blocked airbricks under suspended floors cause damp at low level. Clearing the airbricks is a cheap first step.

Bungalows on the city edge

Ceilings under a poorly insulated loft get cold and grow mould along the edges. Topping up the loft insulation often stops it.

Areas covered

Engineers who cover Norwich work across areas including Eaton, Thorpe St Andrew, Hellesdon, Sprowston, Costessey, Mile Cross, Earlham, Lakenham, Taverham and Drayton.

Questions people in Norwich ask

Can a grant help?

Owners and private tenants in homes rated EPC D to G may get insulation and ventilation through the council's Warm Homes: Local Grant. Council homes are covered by a separate social housing scheme.

Will bleach get rid of it?

Bleach can whiten the surface without killing the roots in plaster or sealant. Use a fungicidal mould wash, dry the area, and fix the moisture source or it will return.
