Leak to dry to treated, one company in Hatfield

Hatfield's housing stock spans Old Hatfield's Georgian and Victorian solid-wall cottages near Hatfield House, 1950s New Town estates in Newtown and Birchwood with flat roofs and system construction, and dense student lets near the University of Hertfordshire. This mix of solid walls, ageing flat roofs and high-occupancy rented homes drives persistent condensation and penetrating damp.

Common causes of mould in Hatfield homes

Flat-roofed 1950s New Town homes

Many houses and maisonettes in Newtown, Birchwood and South Hatfield were built during the town's post-war New Town expansion with flat roofs and minimal loft ventilation. Ageing felt or asphalt roof coverings let rainwater seep into ceiling voids, while poor airflow traps moisture indoors. The result is black mould spreading across bedroom and bathroom ceilings, often mistaken for simple condensation until the leak beneath is found.

Solid-wall period homes in Old Hatfield

The cottages and townhouses around Old Hatfield and Hatfield House predate cavity wall construction, so their solid brick walls readily draw in ground moisture and cold-bridge internally. Without a damp-proof course or adequate insulation, condensation forms on cold external walls, particularly behind wardrobes and headboards pushed against them. Left untreated, black mould takes hold in these unventilated pockets and can spread into adjoining plasterwork and skirting.

High-occupancy rentals near the University of Hertfordshire

With two University of Hertfordshire campuses on its doorstep, Hatfield has a large stock of shared houses and converted flats let to students and young professionals. Frequent showering, drying laundry indoors and limited extractor fan use push humidity levels up in bathrooms and bedrooms, while landlords' repairs are sometimes delayed. Condensation mould quickly develops around window frames, in wardrobes and on north-facing walls.

Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.

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 Hatfield 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.
