Ventilation solutions that keep mould away
Removing mould fixes today. Ventilation fixes next winter. We advise on, supply and install the fans and heat recovery units that take damp air out of Dublin homes.
In short: a family of four puts around ten litres of water into the air every day by cooking, showering, drying clothes and breathing. If it cannot get out, it lands on your coldest walls.
Ventilation options for your home
We recommend the smallest fix that solves the problem, room by room.
Bathroom extractor fans
New installs and replacements for weak, noisy or missing fans. Ducted to the outside, with humidity sensors or run-on timers.
Best for: mould on bathroom ceilings, grout and around the window.
Single-room heat recovery
A through-the-wall unit that swaps damp air for fresh air and keeps the heat in. No ducting through the house.
Best for: bedrooms and living rooms with condensation and cold corners.
Whole-home ventilation advice
For homes with mould in several rooms, we look at how air moves through the whole house and explain the options, from wall vents to central systems.
Best for: recently insulated or very airtight homes.
Why damp air is the real problem
Every shower, meal and wash of laundry puts water into the air. If that air cannot leave, it settles on the coldest wall in the house.
A good ventilation set-up takes the damp air out where it is made and lets fresh air in, so walls stay dry and mould has nothing to grow on.
How we choose the right ventilation
The answer depends on the room, the wall and how the home is used.
- We measure humidity and surface moisture in each affected room
- We check existing fans, vents and where they lead
- We look at heating, insulation and how laundry is dried
- We recommend one fix per room, with a fixed price for supply and fitting
Signs your home needs better ventilation
- Water on the inside of windows most mornings
- The bathroom mirror stays fogged long after a shower
- Mould that comes back in the same spots each winter
- Musty wardrobes or damp-smelling clothes
- A fan that is noisy, or that you cannot hear at all

Ventilation questions
Does ventilation stop mould?
In most Irish homes, yes. The usual cause of mould is condensation: moist indoor air settling on cold walls and windows. Ventilation removes that moist air before it condenses, which takes away what mould needs to grow.
What is the best ventilation for a bathroom with mould?
A correctly sized extractor fan ducted to the outside, with a humidity sensor or run-on timer so it keeps working after a shower. Fans that vent into the attic or are too weak for the room are a common reason bathroom mould returns.
What is a single-room heat recovery unit?
It is a through-the-wall ventilator that takes stale, damp air out and brings fresh air in, passing the outgoing heat to the incoming air. It suits bedrooms and living rooms because it ventilates without making the room cold.
Will ventilation make my home colder?
A humidity-controlled fan only runs when the air is damp, and heat recovery units keep most of the warmth in the room. Dry air is also cheaper to heat than damp air.
Do you install whole-house systems?
We assess the whole home during the survey. For most mould problems, targeted extract fans and single-room heat recovery solve it. If a whole-house system is the right answer, we explain why and what it involves.
Can I get ventilation advice without booking mould removal?
Yes. The free survey covers ventilation on its own. If there is no mould to remove yet, we simply quote for the ventilation.
