We start with a damp and mould survey (£500) to find the cause, then treat the mould and fix the source. Call 020 3051 8478.

Leak to dry to treated, one company in Guildford

Guildford's housing spans Victorian and Edwardian terraces around Charlotteville and Stoughton, solid-walled cottages in Shalford and Artington, 1950s and 60s estates at Park Barn and Westborough, and dense student and professional lets near the University of Surrey and town centre. This mix of old solid walls, concrete post-war construction and heavily occupied rentals leaves many homes prone to condensation, penetrating damp and recurring mould.

Common causes of mould in Guildford homes

Solid-wall terraces in Charlotteville and Stoughton

These Victorian and Edwardian terraces were built without cavity walls, so driving rain and rising groundwater near the Wey valley pass straight through brickwork to the internal plaster. Combined with original single-glazed sash windows and minimal loft insulation, cold external walls attract condensation, and mould develops around window reveals, in chimney breasts and behind wardrobes pushed against outside walls.

Concrete estates around Park Barn and Westborough

Homes on these 1950s and 60s estates were often built with concrete panel or no-fines construction, which suffers pronounced cold bridging at lintels, floor slabs and party walls. Where loft or cavity insulation is patchy, internal surfaces stay cold and warm moist air condenses on them, producing black mould in bathrooms, bedroom corners and behind fitted furniture that residents rarely notice until it spreads.

Overcrowded rentals near the university and town centre

Shared houses and flats near Guildford town centre and the University of Surrey often house more occupants than the property was designed for, generating far more moisture from showering, cooking and drying laundry indoors. Tenants economising on heating and landlords slow to fix extractor fans or leaking guttering allow that moisture to linger, so mould reappears on ceilings and behind beds within weeks of any treatment.

Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.

Tip: Wiping mould off with bleach and repainting hides it for a few weeks, then it returns. Mould is a moisture problem, so unless the condensation, damp or leak feeding it is fixed, it always comes back.

Frequently asked questions

How much does mould removal in Guildford cost?
It depends on the cause and extent. We start with a damp and mould survey at £500 to find the moisture source, then quote the treatment. Treating the surface without the source means the mould returns.
Is black mould in my home dangerous?
Black mould affects indoor air quality and is best removed promptly. We treat the mould and fix the moisture driving it, so the problem is dealt with at the cause.
Will the mould come back after treatment?
Not if the moisture source is fixed. We find and address the cause, whether condensation, penetrating damp or a leak, rather than just cleaning the surface.
Do you find what is causing the mould?
Yes. Every job starts by identifying why the mould is there, using a proper damp and mould survey, so the treatment lasts.
