Fix the leak path, not just the stain
Wet-weather clues checked
We compare the damp pattern with rain, openings and external defects.
Similar faults separated
We distinguish penetration from condensation, rising moisture and plumbing leaks.
Internal damage follows later
We let the area dry before removing and replacing failed finishes.
Trace where rain or water gets through
Penetrating damp usually forms a local patch rather than a neat band along the bottom of a wall. It may darken after heavy rain, spread around an opening or appear below a roof detail. We investigate the outside and inside together, checking likely paths through walls, roofs, joints, windows, doors and failed finishes. Plumbing faults can also produce a similar patch, so pipes and nearby fittings may need attention. Finding the entry point matters because repairing internal plaster alone leaves the water route untouched. Our penetrating damp repair process starts with evidence, helping you avoid paying for a treatment aimed at the wrong form of moisture.
Correct the entry route before making good
Once we identify the likely source, the first task is to stop water entering. The exact repair depends on the fault found and the condition of the surrounding material. The area must then dry before loose plaster, damaged decoration or other failed finishes are removed and reinstated. We also consider condensation and rising damp where the visible pattern is unclear, as several moisture problems can exist in one building. You receive findings, a proposed specification and an estimate before remedial work starts. Free surveys are available for most damp enquiries, so the investigation need not begin with unnecessary treatment.
Frequently asked questions
How is penetrating damp different from rising damp?
Penetrating damp often creates isolated patches that worsen during wet weather or sit near a defect. Rising damp generally forms lower down as ground moisture moves upwards. We inspect the pattern because appearances can overlap.
Can we treat the inside wall without an outside repair?
Not successfully if water is still passing through the building. We first identify and correct the entry route. Once moisture ingress has stopped and the wall has dried, we can address damaged internal plaster and decoration.
What parts of the property might need inspection?
We may need access to the affected room and relevant walls, roofs, joints, openings or plumbing. Clear photographs and details of when the patch worsens help us narrow down the likely route before and during the visit.
