5 Best Mold Removal Services in London (2026)

Pure Maintenance UK is a mould testing and remediation specialist using a patented dry fog technology designed to reduce mould contamination in the air and on surfaces, then help inhibit regrowth. The company builds tailored remediation plans around a property's specific mould problem, covering homes and businesses across the UK from its Orpington base. It positions itself specifically as a mould specialist rather than a general damp or property restoration firm.

Environ Property Services is a Fulham-based damp specialist offering damp surveys, damp proofing, and mould and condensation treatment, alongside period property restoration work across London's Victorian and Edwardian terraces. It positions its process around diagnosing the true structural cause of damp before recommending remedial work, rather than treating surface symptoms alone. The company also runs pest control and general property maintenance services for repeat commercial and residential clients.

Treat Mould Ltd is a London mould and damp treatment specialist offering direct mould removal along with reports detailing the cause and recommendations to prevent recurrence. The company works across residential properties and also serves estate agents on behalf of landlords managing tenanted homes. Its focus stays narrowly on mould and damp treatment rather than broader property restoration or construction work.

LH Specialist Cleaning is a London cleaning company that also handles mould treatment as part of a broader specialist cleaning offering, including after-death cleaning and full showroom or property deep cleans. Reviewers describe the operator, Louis, using a specialised process to trace mould back to its source and treat it thoroughly in a single visit rather than requiring repeat callouts. The business leans more toward specialist and sensitive cleaning work than large-scale property restoration.

Damp and Mould Solutions is a London-based team treating damp and mould issues for both homeowners and landlords, working across bedroom walls, chimney breasts, and other common problem areas. Reviewers, several of them landlords, describe using the company repeatedly across different rental properties. One customer specifically cites a paid survey that correctly diagnosed a chimney-stack leak rather than rising damp, saving further unnecessary work.
