Mould removal and damp treatment in Sunderland
Mould on ceilings, damp patches after rain or a musty bedroom. We pass your request to damp specialists who cover your part of Sunderland.
Most mould in Sunderland homes is condensation, but not all. Walls facing the sea at Roker, Seaburn and Hendon take wind-driven rain, which can soak through tired pointing and show up as damp inside.
Finding out which you have decides the fix. Treating condensation as rising damp, or the other way round, wastes money.

Housing association tenants
26.6% of Sunderland households rent from a social landlord. Under Awaab's Law, which started on 27 October 2025, your landlord must investigate significant damp and mould within 10 working days, send you a written summary within 3 working days after that, and complete safety work within 5 working days of the investigation.
Report it in writing with photos. Keep copies of everything.
Private renters and owners
Private tenants, 14.8% of households, should report damp to the landlord in writing too. Owners, 58.1% of households, need to find the cause themselves or with a specialist.
What a survey covers
Moisture readings at different heights, a look at gutters, pointing and ground levels outside, and questions about cooking, drying clothes and ventilation. Be cautious of a firm that sells injected damp-proofing before measuring.
Our guide to removing mould from walls covers safe cleaning, and the window condensation guide explains why windows run wet.
Sea-facing walls
If damp patches appear after storms from the east, check the pointing, render and window seals on that side. Fixing the outside comes before any treatment inside, or the damp will return.
Sunderland homes and what they need
Single-storey cottages and two-storey terraces
Solid brick walls and low ceilings make for cold corners, and wardrobes pushed against an outside wall hide black spots until they spread. Leave a gap of a few centimetres behind furniture.
Interwar and post-war semis
Cavity walls filled with insulation that later got wet can cause damp patches. A specialist can check whether the fill needs removing.
Newer estate homes
Mould in new homes is usually condensation from shut trickle vents and drying washing indoors. Open the vents and use the extractor fans.
Areas covered
Engineers who cover Sunderland work across areas including Roker, Seaburn, Fulwell, Ashbrooke, Millfield, Hendon, Southwick, Doxford Park, Washington and Houghton-le-Spring.
Questions people in Sunderland ask
Can I paint over mould?
Not until it's cleaned and the cause is fixed. Otherwise it returns through the paint.
Does mould affect health?
It can affect breathing, especially for children and older people. Deal with it early.
