Bathroom Mould & Mildew Treatment

Mould keeps coming back because the cleaning only ever removed the colour. Our bathroom mould and mildew treatment goes after the growth itself — silicone seals, grout lines, ceilings, and the damp corners where it starts — and treats the surface so it stays clear for longer.

Why Bleach on a Cloth Doesn't Fix It

Mould in a bathroom isn’t a stain, it’s a living growth with roots into porous surfaces like grout, silicone, and painted ceilings. Wiping it with household bleach lifts the discolouration and leaves the growth intact, which is why the same black line is back along the shower seal within a fortnight. Persistent damp and mould also carry recognised health implications, particularly for anyone in the house with asthma or allergies.

We treat it differently. The affected surfaces are cleaned and the growth killed with a proper anti-fungal treatment given time to work, not sprayed and immediately wiped. We also identify where the moisture is coming from and tell you plainly, because treatment without ventilation is a temporary result.

What We Treat

We treat grout lines, tiled walls, shower enclosures, silicone seals, ceilings, cornices, window frames, extractor vents, basins, taps, toilets, and drains. Where silicone cannot be recovered, we advise you honestly. We also identify ventilation or moisture issues that may be causing mould and mildew.

A Documented Result

Every mould and mildew treatment follows a documented SOP and ends with a dual-signed handover checklist, giving landlords and property managers a clear treatment record.

Where We Treat Mould

We treat family homes, rental properties, guesthouses, self-catering units, and staff accommodation. For damp caused by leaks or flooding, our flood and water damage cleaning service is the better starting point.

What Sets Us Apart

We treat the growth, not just the colour. A proper anti-fungal treatment is given time to work rather than sprayed and wiped straight off, which is why the result doesn’t reappear within a fortnight.

We tell you what’s causing it. Treatment without addressing the moisture source is a temporary fix. We identify the ventilation or leak issue behind the mould and say so plainly, even when the honest answer is “this needs more than a clean.”

Our mobile units carry their own water and power. Mould treatment needs both, plus drying time, so an outage or a dry tap never leaves a job half-finished.

Frequently Asked Questions

Not for a long time if the moisture source is dealt with. We treat the growth properly and tell you what’s causing it — ventilation, a leak, or drying habits — so you can address it.

 Yes. We use the products as directed and ask that the room is left to ventilate and dry before normal use — we’ll tell you how long on the day.

Most single bathrooms take a few hours. Heavier growth or multiple bathrooms take longer, and we confirm when we quote.

Grout is treated as part of this service. For heavily stained or dirty grout beyond mould, see our tile and grout scrubbing service.
