Fed Up with Damp, Mould, and Condensation?

Common Signs of Poor Ventilation

Bathroom Condensation

Bathrooms naturally create a lot of moisture from baths and showers. If the steam cannot escape properly, condensation forms on ceilings, walls, mirrors and windows.

This is often worse in bathrooms with no windows or several outside walls.

Black Mould Around Baths & Showers

Black mould commonly appears:

  • Around baths and shower trays 
  • On silicone seals 
  • In corners 
  • Around shower screens 

These areas stay damp for long periods, making them ideal for mould growth.

Mould On Tiles & Grout

Tiles and grout regularly get wet and can quickly develop mould if the room is not ventilated properly.

Condensation On Windows & Ceilings

Warm moist air settles on cold surfaces such as:

  • Windows  
  • Window reveals 
  • Ceilings  
  • External walls 

This leaves water droplets behind, which can eventually lead to mould and staining.

Top Floor Mould Problems

Bedrooms and bathrooms on the top floor often suffer the most, especially where there is an unheated loft space above.

Steamed-Up Bedroom Windows

If your bedroom windows are covered in condensation each morning, it’s usually a sign that moisture is trapped inside the property

How Better Ventilation Helps

The right ventilation system removes stale, damp air and replaces it with cleaner, fresher air.

Reduce Condensation & Mould

Good airflow helps prevent moisture settling on walls, ceilings and windows, reducing the conditions mould needs to grow

Improve Air Quality

Cleaner Air, Better Health

Good ventilation keeps your home fresher by removing stale air, excess moisture, and everyday pollutants. Lower humidity helps reduce dust mites and mildew, and systems with built‑in filters bring in cleaner air — ideal for anyone with asthma, allergies, or hay fever.

Protect Your Property

Excess moisture can quietly damage your home. It can ruin paintwork, plaster, ceilings, timber, tiles, and window frames. Proper ventilation stops damp before it becomes a costly repair job.

  • Prevents long‑term damage: Dry walls and ceilings last longer and stay in better condition.
  • Keeps your home looking fresh: No more scrubbing black spots off paint, grout, or window sills.
  • The golden rule: When we stop the condensation, we stop the black mould.

Energy‑Efficient Solutions

Modern ventilation systems cost pennies to run — many use less power than an old 60‑watt lightbulb.

How Our Systems Fix the Problem

  • Stops mould at the source: By removing moist air, we take away the conditions mould needs to grow.
  • Low running costs: High‑performance systems with extremely low energy use.

Ventilation Systems We Install

At Gilly’s Electrical, we install a range of ventilation systems tailored to your home and the type of condensation problem you’re facing.

High‑Power Bathroom Extractor Fans

Our most popular choice is an in‑line extractor fan fitted in the loft, with a neat ceiling grille in the bathroom. These fans are powerful, quiet, and continue running after the light is switched off to clear steam properly.

Kitchen Extractor Fans

Cooking releases a huge amount of moisture. A properly ducted kitchen extractor fan removes steam, grease and odours before they spread through the home.

Positive Input Ventilation (PIV)

PIV systems bring filtered, fresh air into the property and push out stale, moisture‑filled air. They’re ideal for whole‑house condensation issues and homes with steamed‑up windows every morning.

Wall‑Mounted Extractor Fans

Where loft access or ducting is limited, wall‑mounted fans offer a practical alternative. For stronger performance, we usually recommend centrifugal wall‑mounted fans.

We provide a complete, straightforward service from start to finish:

Damp & Mould Surveys — We inspect your home, identify why moisture is building up, and explain the best fix.

Ventilation Systems & Features We Offer

At Gilly’s Electrical, we install a range of ventilation systems designed to tackle condensation, damp and mould at the source. Every home is different, so we match the right system to the right problem.

Systems We Install

High‑Power Bathroom Extractor Fans

Our most popular option. A powerful in‑line fan is fitted in the loft, leaving only a neat ceiling grille in the bathroom. It’s quiet, efficient, and keeps running after the light is switched off to clear steam properly.

Kitchen Extractor Fans

Cooking releases a huge amount of moisture. A properly ducted kitchen extractor removes steam, grease and odours before they spread through the home.

Positive Input Ventilation (PIV)

PIV systems gently introduce filtered fresh air into the property, pushing out stale, moisture‑filled air. Perfect for whole‑house condensation issues and homes with steamed‑up windows every morning.

Wall‑Mounted Extractor Fans

Where loft access or ducting is limited, wall‑mounted fans are a practical alternative. For stronger performance, we recommend centrifugal wall fans, which move air far better than standard axial types.

Outside Wall Fans

In kitchens and bathrooms where extra power is needed, we can mount a heavy‑duty centrifugal fan on the exterior wall. This gives far better extraction than typical indoor wall fans.
