Have you noticed condensation building up on your windows, or are those pesky mould spots appearing on your walls again?
It’s frustrating, right? Not only does it make your home feel uncomfortable, but it can also cause lasting damage to your property and impact your health. So, why let mould and condensation continue to take over your home?
Which method should I use?
The key to preventing mould and condensation in your home is to use the appropriate method. To give you some advice and more of an idea in selecting the finest solutions, below are some methods.
Method | How It Works | Pros | Cons |
PIV system | Condensation Ventilation System constantly brings in fresh air while expelling stale, humid air from your house. This steady airflow helps avoid mould growth and condensation by lowering humidity levels. It is a solution for the entire house. | – Effective year-round – Reduces mould and condensation – Improves indoor air quality – Energy-efficient – Minimal maintenance required | – Initial installation cost – Best for larger homes or homes with persistent issues |
Dehumidifiers | Dehumidifiers draw in damp air, dry it, and then redistribute the dry air back into the space to remove moisture from the air. This lessens condensation by keeping the air dry. | – Fast results – Portable and flexible – Easy to use in specific rooms | – Needs frequent tank emptying – Can be noisy – Not effective in large areas or for long-term moisture control |
Insulating Window Kits | By adding a layer of insulation to windows, these kits stop condensation from forming on cold surfaces. They contribute to keeping interior temperatures higher. | – Affordable – Easy to install – Reduces window condensation and energy loss | – Temporary fix for Windows only – Doesn’t address overall humidity or mould growth – Limited effectiveness |
Proper Ventilation | By allowing fresh air to flow and damp air to escape, ventilation systems—like extractor fans or just opening windows—avoid condensation buildup. | – Low-cost – Simple to implement – Helps control moisture levels | – May not be enough for large or damp areas – Requires consistent effort to maintain airflow |
Home Insulation | Ventilation systems, such as extractor fans or simply opening windows, allow fresh air to circulate and moist air to escape, preventing condensation buildup. | – Fast results – Portable and flexible – Easy to use in specific rooms | – High upfront cost – Takes time to install – Doesn’t address humidity issues directly |
Why choose PIV units for mould and condensation

You need a solution that works throughout your house,
not just in certain places, to deal with mould and dampness. Although the other methods are all useful, a PIV (Positive Input Ventilation System for Mould) system provides a better, longer-lasting solution.
Although they only function in small spaces and need ongoing care, dehumidifiers can offer rapid relief. Conversely, a PIV system requires less maintenance and automatically controls the humidity levels in your house. In a similar vein, window kits lessen condensation on glass but do not improve general moisture, endangering walls and ceilings. Every surface is kept dry by a PIV system.
PIV systems provide continuous airflow without you lifting a finger
Basic ventilation, like extractor fans or opening windows, requires effort and doesn’t always work for larger areas. Home insulation may save energy, but it can trap moisture, worsening condensation. PIV complements insulation by removing excess humidity and keeping your home warm and dry.
With year-round effectiveness, energy efficiency, and low maintenance, a PIV system is the smart choice for protecting your home. Say goodbye to dampness and enjoy a healthier, more comfortable living environment. Choose PIV for long-term peace of mind!
(FAQs)Frequently Asked Questions

Why is condensation an issue, and what does it mean?
When warm air and a cold surface come into contact, condensation occurs, forming water droplets. Your home may sustain damage, mould growth, and wet areas as a result.
How does mould develop?
Wet places are ideal for mould growth. Uncontrolled condensation provides the ideal conditions for mould growth, which can lead to damage and health problems.
PIV systems: What are they?
By eliminating moist air and bringing in fresh, dry air, a PIV system lowers humidity and avoids condensation in your house. It’s a long-term fix for the entire house.
Should I use a PIV system or a dehumidifier?
While dehumidifiers are effective in certain areas, a PIV system regulates humidity and keeps moisture at bay throughout your house.
What’s the most cost-effective solution?
Enhancing ventilation, such as with extractor fans or dehumidifiers, is frequently the least expensive option. An affordable long-term answer for your whole house is a PIV for Condensation system.
How much maintenance is required?
PIV systems require little upkeep (clean filters). Dehumidifiers need to be cleaned and emptied regularly. Insulated windows require minimal maintenance.
