Can you really diagnose damp from photos?+
For most cases, yes: the pattern, location, season and your answers point clearly to one cause. When they do not, we say so and recommend the on-site tier with moisture readings.
Do you do the repairs?+
Yes. Home Art Build carries out the fix packages — ventilation, insulation, external sealing, PIV units and, where properly diagnosed, rising damp treatment — at a fixed price with a guarantee.
I am a landlord. Does this cover Awaab's Law?+
The report includes a dated investigation record, the hazard classification, required actions and target dates, plus a tenant communication template. It is written to sit in your compliance file.
