The Ultimate Guide to Mould Treatment in Housing & Commercial Spaces

The Ultimate Guide to Mould Treatment in Housing & Commercial Spaces

The introduction of Awaab's Law represents a major shift in how damp and mould issues must be handled within social housing. The legislation places clear responsibilities on landlords, housing associations and local authorities to respond to hazards more quickly than ever before.

With strict investigation and repair timescales now in place, housing providers need reliable systems that not only remove mould but help prevent it from returning.

The Zinsser MouldAway Kit offers a complete preparation, treatment and protection system designed to help property managers tackle mould effectively while supporting long-term compliance goals.

What is Awaab's Law?

Awaab Ishak was just two years old when he tragically died in 2020 from a respiratory condition linked to prolonged exposure to mould in his family home. Despite repeated complaints being made to the landlord, no meaningful action was taken to remove the hazard.

Following a campaign led by housing charities and national media organisations, the government introduced Awaab's Law, establishing clear legal duties for social housing providers when dealing with damp and mould-related issues.

The legislation aims to ensure that tenants live in safe, healthy homes and that serious hazards are addressed without delay.

Why Damp and Mould Can No Longer Be Ignored

Damp and mould are more than cosmetic problems. Left untreated, they can:

  • Cause structural damage to properties
  • Trigger respiratory conditions
  • Aggravate asthma and allergies
  • Impact tenant wellbeing
  • Lead to costly repair programmes

For housing providers, recurring mould issues can also create compliance risks, increased maintenance costs and reputational damage.

This is why a proactive approach to mould prevention is now more important than ever.

What Does Awaab's Law Require?

Social landlords are expected to respond quickly when hazards are reported.

Key requirements include:

  • Investigating emergency hazards within 24 hours
  • Investigating significant damp and mould hazards within 10 working days
  • Providing written finding within 3 working days
  • Beginning repair work within 5 working days where required
  • Taking action to prevent hazards from returning

Failure to act appropriately may result in legal action. enforcement measures and significant financial penalties.

Why Surface Cleaning Alone Isn't Enough

One of the biggest misconceptions surrounding mould treatment is that simply cleaning visible mould resolves the problem.

Unfortunately, mould often returns when full treatment process is not followed correctly.

Effective mould remediation requires:

  • Surface preparation
  • Mould treatment 
  • Stain blocking
  • Long-term protection

Without each stage, mould can quickly reappear, resulting in repeat visits and increased maintenance costs.

The Zinsser MouldAway Kit: A complete Mould Treatment System

To simplify the mould treatment process, the Zinsser MouldAway Kit combines four professional-grade products into one complete system.

Designed for housing associations, landlords, maintenance teams and facility managers. the kit helps to ensure every stage of the mould treatment process is covered.

Step 1: Prepare the Surface

Universal Degreaser & Cleaner

Preparation begins with a thorough clean.

The Universal Degreaser & Cleaner:

  • Removes grease, dirt and contaminants 
  • Creates a clean surface
  • Improves adhesion of subsequent coatings
  • Features a fast-drying, water-based formula.

Proper preparation helps ensure the remaining products perform as intended.

Mould Killer & Remover

The Mould Killer & Remover:

  •  Eliminates mould, fungi and algae
  • Helps stop spores spreading

  • Can be applied prior to priming and decorating

This stage tackles the mould itself before protective coatings are introduced.
