Decorating basement and lower-ground rooms
Below-ground rooms are where decorating advice most often goes wrong. Paint is asked to solve a moisture problem it was never designed to touch, and the same wall is redecorated every eighteen months.

Diagnosis before decoration
Readings, a look at ventilation, and an honest conversation about whether the moisture is condensation, penetrating damp or a failed tanking system. Only then is there any point discussing coatings.
Moisture readings recorded and shared
Ventilation and extraction reviewed
Tanking or structural issues referred on rather than painted over
What coatings can genuinely do
Where the cause is condensation and the room is otherwise sound, sterilising the surface and using a system suited to humid environments makes a real difference. Where water is entering the structure, no coating will hold.
Making the room feel less like a basement
Light, sheen and colour do a lot of work below ground. A slightly warmer white and a mid-sheen finish reflect what limited natural light there is instead of absorbing it.
3 questions we get about this building type
- Can you paint over damp basement walls?
- Not honestly. We will take readings and tell you what needs resolving first — coating a wet wall wastes your money and our time.
- Will anti-mould paint solve it?
- It slows surface growth where the cause is condensation. It does not stop water entering a structure.
- Do you work with damp specialists?
- We will refer you on where the problem is structural and pick the decoration up once the remedial work is complete and dry.
