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 Hartfield

Hartfield's housing mix runs from medieval Wealden hall houses and sandstone cottages to weatherboarded and tile-hung Victorian properties, many listed, alongside farmhouse and oast conversions on the fringe of Ashdown Forest. Solid, uninsulated walls, small windows and heavy clay subsoil combine to trap moisture, giving black mould plenty of opportunity to establish on cold surfaces.

Common causes of mould in Hartfield homes

Solid sandstone and timber-framed walls with no cavity

Many Hartfield cottages were built with solid sandstone or timber-framed construction predating cavity walls, so driving rain off the forest can push straight through to the inner face. Without a break in the wall, moisture tracks to the coldest internal surfaces, and black mould spreads across external walls, in corners and behind wardrobes and headboards pushed up against them.

Clay ground and forest-edge rainfall causing rising damp

Hartfield sits on heavy Wealden clay close to Ashdown Forest, where ground stays saturated for long spells and older cottages often lack a working damp proof course. Rising damp creeps up skirtings and lower walls, keeping plaster permanently moist. Combined with condensation from cooking and bathing in low-ceilinged rooms, this produces mould around window reveals, in bathrooms and along bedroom walls.

Listed buildings limiting insulation and ventilation upgrades

A good number of Hartfield's period and listed properties restrict changes such as external insulation, uPVC glazing or visible extractor fans, so householders are left with original single glazing and limited airflow. Warm moist air condenses on cold glass and reveals, and in converted lofts or oast-style outbuildings this settles as persistent mould that ordinary wiping cannot keep from returning.

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 Hartfield 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.
