Leak to dry to treated, one company in New Southgate

New Southgate's housing runs from Victorian and Edwardian terraces around Brunswick Park Road and Betstyle Road to 1930s semis near Station Road and blocks of flats close to the station. Solid brick walls, ageing render, poorly ventilated conversions and older sash windows all trap moisture, giving damp and mould plenty of ways into local homes.

Common causes of mould in New Southgate homes

Solid-wall Victorian and Edwardian terraces

Many terraces around Brunswick Park Road and Betstyle Road were built with solid brick walls and no cavity, so they rely on breathable finishes and clear guttering to stay dry. Cement render, blocked airbricks or leaking rainwater goods let moisture track through the wall, showing up as black mould on chimney breasts, behind wardrobes and around ground-floor skirtings.

1930s semis with rendered bay windows

The semi-detached streets near Station Road and towards Bowes Park typically have rendered elevations and steel-framed or timber bay windows original to the 1930s build. Hairline cracks in ageing render and worn seals around these bays let rain penetrate, while original single glazing encourages condensation, so mould commonly gathers on bay window reveals, ceilings above them and adjoining bedroom walls.

Flat conversions and HMOs near New Southgate station

Properties subdivided into flats close to New Southgate station often have shared party walls, limited through-ventilation and bathrooms without working extractor fans. Cooking and drying laundry indoors raises humidity quickly, and with nowhere for that moisture to escape, mould develops on external corners, behind furniture pushed against cold walls and around window frames in bedrooms and living areas.

What our customers say

★★★★★

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 Southgate 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.
