Why Mould Keeps Coming Back

Painting over mould or wiping it with bleach only hides the problem. Without proper ventilation, moisture builds up and mould returns within weeks. Here’s why it matters:

🏥

Property Damage

Persistent damp rots window frames, damages plaster, ruins decoration, and can even compromise the structural integrity of your home over time.

🩪

Health Risks

Black mould releases spores linked to respiratory problems, allergies, and asthma — particularly dangerous for children, the elderly, and anyone with existing conditions.

💰

Rising Costs

Ignoring damp and mould means bigger repair bills down the line. Early intervention with proper ventilation saves you thousands in remedial work.

Extractor Fans — Targeted Moisture Removal

Bathrooms and kitchens produce huge amounts of steam and moisture every day. A properly installed extractor fan removes that damp air before it settles on walls and ceilings.

How Extractor Fans Help

Modern extractor fans are quiet, energy-efficient, and can be set to run automatically when humidity rises or when lights are switched on. We install them in:

  • Bathrooms and en-suites
  • Kitchens and utility rooms
  • Internal rooms with no windows
  • Shower rooms and wet rooms

Every installation is carried out to current Building Regulations, with proper ducting to the outside — not into loft spaces where moisture causes even more damage.

PIV Units — Whole-Home Mould Prevention

Positive Input Ventilation is the single most effective way to eliminate condensation and mould throughout your entire home — not just one room.

How PIV Units Work

A PIV unit is installed in your loft and gently pushes filtered, dry air down into your home. This creates a slight positive pressure that forces stale, moisture-laden air out through natural gaps and vents.

  • Eliminates condensation on windows and walls
  • Stops black mould from forming anywhere in the home
  • Filters incoming air — reduces dust and allergens
  • Virtually silent operation — you won’t know it’s there
  • Low running cost — typically pennies per day

PIV is recommended by Environmental Health Officers and is widely used by housing associations and councils across the UK to combat damp and mould.

Frequently Asked Questions

What’s the difference between an extractor fan and a PIV unit?
An extractor fan removes damp air from a single room — typically a bathroom or kitchen. A PIV (Positive Input Ventilation) unit treats your entire home by pushing fresh, filtered air from the loft down through the house, creating positive pressure that forces stale, moist air out. If your mould problem is limited to one room, an extractor fan may be enough. If it’s affecting multiple rooms, a PIV unit is usually the better solution.
How much does it cost to install an extractor fan?
The cost depends on the type of fan, the room layout, and whether new ducting is needed. We provide a free, no-obligation quote after assessing your property. Every quote is clear and transparent with no hidden charges.
How much does a PIV unit cost to run?
PIV units are incredibly energy-efficient. Most models cost just a few pence per day to run — roughly the same as a low-energy light bulb. The savings you make on redecorating and mould treatment far outweigh the running costs.
Will a PIV unit make my house cold?
No. Modern PIV units draw air from the loft space, which is typically warmer than outside air due to heat rising through your ceiling. Many units also include a built-in heater to gently warm the air before it enters your living space, so you won’t notice any drop in temperature.
How long does installation take?
A bathroom extractor fan typically takes 1-2 hours to install. A PIV unit installation usually takes 2-3 hours. We keep disruption to an absolute minimum and always leave your home clean and tidy.
Do I need an extractor fan if I have a window?
Building Regulations actually require mechanical ventilation (an extractor fan) in bathrooms — even if you have a window. In practice, people rarely open windows in winter when condensation is at its worst, so a fan ensures moisture is removed all year round.
Can you help with a landlord or housing association property?
Absolutely. We work with private landlords, letting agents, and housing associations across South Yorkshire. Under current legislation, landlords have a legal duty to ensure properties are free from damp and mould hazards. We can provide professional assessments and install the right ventilation to bring properties into compliance.
