Why Thornton Heath homes get damp, mould and hidden leaks
Thornton Heath is one of the most densely populated parts of the Croydon borough, built almost entirely on tightly packed Victorian and Edwardian terraces, much of it now converted flats, HMOs and rented homes. That combination is exactly why damp and mould are so common here. In the terraces we most often trace leaks behind bay windows, valley gutters and chimney breasts, penetrating damp through solid walls, and slow concealed pipe leaks under solid floors. In the many shared and rented homes the recurring issue is persistent condensation mould in cold, overcrowded and poorly ventilated rooms, alongside escape of water between flats. We survey and diagnose the real cause first rather than guessing or painting over it.
Landlords, HMOs and Awaab’s Law in Thornton Heath
With so much rented and HMO housing in CR7, damp and mould are no longer something to leave. Under Awaab’s Law, social landlords must investigate reported damp and mould within set timescales, make emergency hazards safe within 24 hours, and provide a written summary of the investigation. We give landlords, letting agents and housing teams a proper independent investigation of the real cause — whether it is a hidden leak, penetrating damp or condensation — with the clear written report needed to act quickly and correctly, protecting tenants and reducing the risk of complaints and disrepair claims. Where a hidden leak is behind the problem, we trace and access it non-invasively, then plan the right mould treatment and ventilation so it does not simply return.

Frequently asked questions — Thornton Heath
I’m a landlord with a damp and mould complaint — what do you provide?
An independent investigation of the real cause and a clear written report. That helps you meet your obligations under Awaab’s Law and actually fix the problem rather than repainting over it.
My rented flat or HMO room has mould that keeps coming back — why?
Because mould is a symptom. If the moisture source, whether a leak, condensation or damp, is not fixed, it returns. We find the cause first, then treat the mould and advise on ventilation.
We have a leak from the flat above — can you help?
Yes. Escape of water between flats is common in Thornton Heath’s converted terraces. We trace the source, establish whether it is demised or communal, and document it for the freeholder, managing agent and insurer.
Will my insurance pay for the work?
Trace and access may be covered under buildings insurance, depending on the policy. We provide insurance-ready reports and evidence to support the claim.
How fast can you get to Thornton Heath?
Thornton Heath is well within our regular South London area, so we can usually attend CR7 the same day, and we run genuine 24/7 emergency call-outs.
