Core Handyman Services – Why Mould Keeps Returning in Homes, Advice From a Local Chelmsford Handyman

Mould is one of the most frustrating problems homeowners face, especially when it keeps coming back despite repeated cleaning or repainting. Across Chelmsford, this is particularly common in colder rooms such as porches, spare bedrooms, bathrooms, and areas with external walls.

At Core Handyman Services, mould issues are dealt with by addressing the cause, not just the visible marks on the wall.

Why Cleaning and Painting Often Doesn’t Work

Many mould problems reappear because the underlying conditions haven’t changed. Simply wiping the surface or painting over the area may improve the appearance temporarily, but it rarely provides a lasting solution.

Common reasons mould returns include:

• Cold external walls attracting condensation

• Poor airflow within the room

• Moisture trapped behind furniture

• Incorrect preparation before painting

Without tackling these factors, mould is likely to reappear regardless of the paint used.

Cold Walls and Condensation Explained

When warm air inside a home meets a cold surface, moisture forms. Over time, this condensation creates an environment where mould can thrive.

Rooms most affected in Chelmsford properties often include:

• Porches with single-skin brickwork

• North-facing bedrooms

• Corners of rooms with limited airflow

• Bathrooms with inadequate ventilation

Understanding where moisture is coming from is key to stopping mould long term.

Proper Preparation Before Decorating

One of the biggest mistakes is applying paint directly onto mould-affected or stained surfaces without proper preparation.

Correct preparation may involve:

• Treating and removing mould properly

• Allowing walls to fully dry

• Sealing affected areas where necessary

• Using coatings suitable for problem environments

Skipping these steps usually leads to mould bleeding back through the paint.

Why Standard Emulsion Paint Often Fails

Standard emulsion paints are not designed to cope with ongoing moisture or condensation. Even specialist paints can fail if applied over poorly prepared surfaces.

For long-lasting results, the background surface needs to be stable, dry, and correctly treated before any finish coats are applied.

Furniture Placement and Airflow

Mould often forms behind wardrobes, sofas, and beds placed tightly against external walls. This restricts airflow and allows moisture to build up unnoticed.

Simple adjustments can help:

• Leaving a small gap behind furniture

• Improving ventilation where possible

• Avoiding blocking air movement in cold rooms

These changes work best alongside proper wall preparation and repair.

Long-Term Solutions, Not Short-Term Fixes

Covering mould without addressing the cause often leads to repeated redecorating and further damage to plaster and paint finishes. A methodical approach saves time, money, and frustration in the long run.
