Damp & Mould Treatment
Damp and mould treatment across Birmingham typically runs from £350 for a single-wall mould wash and repaint through to £2,500+ for a full damp-proof course injection with replastering, depending on the cause and extent. We start with a proper diagnosis rather than assuming rising damp, since penetrating damp and condensation need different fixes, and give you a fixed quote for the correct treatment before any work begins.
What's included
A full survey to identify whether you have rising, penetrating or condensation damp, using a moisture meter rather than guesswork. Treatment matched to the cause: chemical or physical damp-proof course injection, external repairs to fix penetrating damp at source, or extractor fans and positive input ventilation for condensation. All affected plaster is stripped back, mould-washed with an anti-fungal treatment, and re-plastered ready for redecoration.
Damp treatment for landlords, HMOs and letting agents
Damp and mould is a licensing and Awaab's Law compliance issue for HMOs and rented properties, and we provide a written report with photos that you can use for tenant correspondence or council inspections. We prioritise urgent HMO cases and can usually get a surveyor out within 48 hours. As a VAT-registered contractor we invoice landlords, management companies and housing associations directly.
Frequently asked questions
How do I know if it's damp or just condensation?
Condensation appears as fine water droplets and black speckled mould, usually on cold spots like external walls, window reveals and bathroom ceilings, and gets worse in winter. Rising or penetrating damp tends to show as a tide mark, crumbling plaster or a persistent musty smell, and isn't fixed by ventilation alone. We can usually tell over the phone from a photo, but our survey confirms it with a moisture meter.
Will you fix the cause or just paint over the mould?
We always treat the cause first, whether that's an external repair, a new damp-proof course or better ventilation. Painting over mould without addressing the source just delays it coming back, usually within a few months, so we won't offer that as a standalone fix.
How long does it take to dry out after treatment?
A DPC injection typically needs 6-12 weeks for the wall to dry before replastering, though we can often replaster with a breathable membrane sooner to keep disruption down. Condensation and mould treatments dry within days once the ventilation fix is in place. We'll give you a realistic timeline for your specific job at the survey stage.
Do I need to move out during treatment?
For a mould wash or small localised repair, no. For a full damp-proof course injection you can usually stay, though the room being worked on will be out of use for a few days while plaster is stripped and injected. For extensive penetrating damp repairs affecting multiple rooms, we'll talk you through what to expect at the survey.
Is damp treatment covered by insurance?
It depends on the cause and your policy. Most standard policies exclude condensation and gradual rising damp as a maintenance issue, but sudden penetrating damp from a leak or storm damage is often covered. We can provide a report you can submit with a claim, though we'd always recommend checking with your insurer first.
