Leak to dry to treated, one company in New Barnet

New Barnet's housing runs from Victorian and Edwardian terraces around the high street to 1930s bay-fronted semis on the roads off Station Road and Somerset Road, plus interwar and postwar flats near the railway. Solid brick walls, original single glazing and chimneybreasts left unlined all limit how well these homes cope with moisture, making condensation and penetrating damp persistent problems.

Common causes of mould in New Barnet homes

Solid-wall terraces and chimneybreasts holding damp

Many of New Barnet's Victorian and Edwardian terraces near the high street have solid brick walls with no cavity, so driving rain and rising groundwater can work through to the inside face. Redundant chimneybreasts, often boxed in during past renovations, trap moisture and turn black with mould at skirting and ceiling level, especially where old lime plaster has been replaced with modern cement render.

1930s bay-window semis with cold spots

The bay-fronted semis common on roads off Station Road and East Barnet Road were built with thin single-glazed frames and minimal wall insulation. These create cold bridging around window reveals and in box rooms above bay extensions, where warm moist air condenses on cold plaster. Mould rings appear on reveals, ceilings and behind wardrobes pushed against external walls in these smaller bedrooms.

Converted flats and shared houses near the station

Properties subdivided into flats around New Barnet station and along the Great North Road often have bathrooms without working extractor fans and kitchens venting into shared hallways. Higher occupancy means more cooking, showering and clothes drying indoors, so moisture builds faster than these older buildings can shed it, leaving mould behind furniture, in cupboards and along skirting in bedrooms and bathrooms alike.

★★★★★

I recently used a damp and mould specialist company and was extremely impressed with the service from start to finish. From the initial survey, they were knowledgeable, thorough, and took the time to clearly explain the cause of the issue rather than just treating the symptoms.

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 New Barnet 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.
