Black mould and streaming windows traced to the real cause, then fixed with ventilation and moisture control that lasts. Covering Woking & Weybridge, Kingston & Surbiton and Epsom & Ewell and across Surrey.
Book a surveyCondensation is the most common cause of black mould in Surrey homes, and it often gets mistaken for rising or penetrating damp. Bleach and mould-resistant paint only treat the symptom.
Our surveyors take humidity, temperature and surface readings to understand why moisture is building up in your property, then recommend changes that stop the mould returning.
In Surrey we find condensation in everything from 1930s semis with replacement windows and blocked vents to modern flats and extended family homes. Our condensation work in Surbiton is typical: humidity readings, a clear diagnosis and ventilation changes that stopped the mould returning.
Surrey has an unusually wide mix of property: Victorian villas in Surbiton and Kingston, Edwardian and interwar family homes across Elmbridge and Epsom, and centuries-old timber-framed cottages, barns and farmhouses in the villages around Guildford, Dorking and Godalming. Older solid-walled and timber-framed buildings need breathable, sympathetic repairs, while interwar cavity-walled homes are prime candidates for wall tie corrosion.
Leafy plots, mature trees close to houses and many older properties with suspended timber floors mean sub-floor ventilation is often restricted. Blocked air bricks and damp sub-floors are a common starting point for wet rot, dry rot and woodworm in Surrey homes.
Edwardian and interwar homes alongside modern apartments, where condensation in well-sealed flats and wall tie corrosion in older houses are common.
Victorian villas and terraces, many split into flats, close to the Thames, so failing original damp proof courses and damp cellars are part of our everyday work there.
Interwar semis and Edwardian family homes on clay, where corroded wall ties, cracked brickwork and bridged damp proof courses are frequent findings.
Every home produces moisture from cooking, showering, drying clothes and simply breathing. When warm, moist air meets a cold surface such as a window, an external corner or an uninsulated wall, it condenses. Where ventilation can't remove that moisture fast enough, black mould follows.
Solutions depend on the property. They may include positive input ventilation (PIV) units that gently replace moist air with filtered fresh air, continuous-running extractor fans in kitchens and bathrooms, humidity-controlled fans, improved trickle ventilation, or insulating cold spots. We also check for hidden leaks and penetrating damp that can make condensation worse.

If you’ve noticed any of these issues, arranging a professional survey is the best way to identify the cause and prevent further damage.
In winter, windows are closed, heating cycles on and off and walls are colder, so moisture has fewer ways out and more cold surfaces to condense on. Improving ventilation is usually the long-term fix.
It can help in a single room but rarely fixes the cause on its own. A whole-house approach to ventilation and cold spots is more effective and cheaper to run long term.
It depends on the cause. Lifestyle plays a part, but the building's ventilation, insulation and condition are often the main factors. Our independent report helps landlords and tenants in Surrey understand what is causing the problem.
Persistent mould and damp can affect indoor air quality and may aggravate allergies, asthma and other respiratory conditions in some people, so it is worth tackling promptly.
Tapco has been based in Thames Ditton since 1971, with an office in Esher too, so we are rarely more than a short drive from any Surrey property.
Yes. We regularly survey and treat listed and period properties around Guildford, Dorking, Godalming and the Surrey villages, using breathable, lime-compatible materials where the building needs them.
