Waterproofing
Damp on an internal wall is usually water arriving from outside, not condensation. The repair belongs on the external face, and painting the inside before that is done simply hides it for a few months.

Priced per square foot of external face covered.
Ground floor is straightforward; upper floors need access equipment and take longer.
Isolated hairlines are quick; widespread crazing needs full raking and filling first.
Our Process
We work out where water is actually getting in, which is often above the damp patch inside.
Loose material is removed and cracks raked out.
Cracks are filled and reinforced before coating.
A weather-resistant waterproof coating is applied to the external face.
We check after the next heavy rain to confirm the wall stays dry inside.
FAQs
Straight answers to the questions customers ask us most about this service.
Because water is already in the wall by that point. An internal sealer traps moisture inside the plaster, and it typically pushes the problem sideways or blows the paint off a few months later. Stopping water at the external face is the repair that lasts.
Timing is the clearest indicator. Seepage worsens after heavy rain and dries out in a run of dry days. A pipe leak is steady regardless of weather and often grows. If the patch never dries, we would investigate for a pipe before treating the external wall.
Not straight away. The wall needs to dry out fully first, and how long that takes depends on how wet it got and how well the room ventilates. Painting over a wall that is still damp is the most common reason the same patch reappears.
Not usually. Damp that is worst at skirting level and fades upward is more likely to be rising damp from the ground, and an external coating higher up will not touch it. That needs a different approach, and we will say so rather than sell you a coating that cannot help.
