PIV Unit Installation Services
Professional Positive Input Ventilation Installation
Condensation on windows, stale air, black mould and damp patches are often signs that a home has poor air circulation. When humid air cannot escape, excess moisture settles on cold surfaces such as windows, an external wall, outer walls and ceilings. Over time, this can lead to mould growth, a persistent damp problem and costly repairs.
Condensation Cured provides PIV unit installation for homes, landlords and properties affected by condensation problems, mould problems and poor indoor air quality. We supply and install suitable PIV systems designed to bring fresh filtered air into the property, reduce condensation and help create a healthier indoor environment.
Our experienced PIV installers will assess your property, recommend the right PIV unit and make sure it is installed correctly. Contact our team today to discuss your condensation problem and get advice on whether a positive input ventilation system is right for your home.
What is a PIV unit?
A PIV unit is a ventilation unit that gently introduces filtered air into a property at a continuous rate. This helps replace stale air, dilute moisture-laden air and improve air quality throughout the home.
Most positive input ventilation systems are installed in the loft space. A loft-mounted PIV unit usually delivers air into a central location, such as a hallway or landing. From there, fresh air moves through the property and helps push humid air out through natural leakage points.
Where a home does not have suitable loft space, a wall-mounted positive input ventilation unit may be recommended instead. Some properties may also benefit from a heated unit, especially where there are concerns about cold air, cold weather or making the house colder.
A positive input ventilation PIV system works best when it is matched to the building. The right system depends on the size of the home, the moisture level, existing ventilation, the filtration system, the layout and how air moves between rooms.
How PIV Unit Installation Helps Condensation and Mould
A professionally installed PIV system can be an effective solution where the main issue is excess moisture and poor ventilation.
Everyday activities such as cooking, showering, drying clothes and breathing add moisture to the air. When the temperature drops, this humid air can settle on cold surfaces and external walls. This is why condensation problems are often worse in winter.
A PIV system helps by:
Increasing airflow through the property.
Introducing fresh filtered air.
Helping reduce stale air and indoor pollutants.
Diluting moisture-laden air.
Supporting better indoor air quality.
Helping prevent condensation and mould growth.
Reducing the risk of black mould returning.
Creating a more comfortable living environment.
PIV can also support health benefits linked to improving indoor air quality, especially in homes where stale air, mould and excess moisture may aggravate respiratory problems.
It is important to be clear: PIV will not fix every damp problem. If there is a leak, structural defect or separate damp proofing issue, that should be investigated. But where the cause is poor ventilation and trapped moisture, PIV can be a cost effective solution.
Which PIV Unit is Right for my Property?
Not every property needs the same unit. A small house, flat or bungalow may need a different system from a large house with more rooms or higher moisture levels.
Before we install a PIV, we look at:
Whether there is suitable loft space.
Whether a loft-mounted or wall-mounted unit is better.
Whether a heated unit is needed.
How air moves through the property.
Existing extractor fans and ventilation.
The number of rooms affected by condensation.
Any concerns about cold air or the house feeling cold.
The level of mould growth or black mould present.
The likely running cost and maintenance needs.
A common concern is whether a PIV will make the house cold. A PIV system brings in outside air, but the right unit should be selected to avoid cooling the home unnecessarily. Heated unit options can help temper incoming air when the temperature drops.
Our aim is to recommend the right system for the property, not simply install a PIV where it is not suitable.
How Our PIV Installation Service Works
Our PIV installation process is clear and practical.
First, we discuss the issue. This might include condensation on windows, mould growth, stale air, damp smells, poor air quality or concerns about excess moisture.
Next, we recommend a suitable system. This may be a loft-mounted PIV unit, a wall-mounted unit or another ventilation option depending on the property.
We then install the system carefully and with minimal disruption. Many straightforward installations can be completed in a few hours, depending on access, wiring, building regulations and the type of unit required.
Once the PIV unit installed is working, we check the airflow and explain how the system works. We also advise on filters, maintenance, running costs and how to keep the system performing properly.
PIV Installation Cost
The PIV installation cost depends on the unit, the property and the work required. A standard loft-mounted system will usually have different requirements from a wall-mounted system or a heated unit.
The main factors that affect installation cost include:
The type of PIV unit.
Whether the system is heated.
Loft access and available space.
Electrical requirements.
Property size and layout.
Existing ventilation.
Whether extra extractor fans or repairs are needed.
The level of condensation or mould present.
Some customers ask whether PIV systems are expensive. The better question is whether the system is suitable for the property and likely to solve the problem. A correctly specified system can be cost-effective when compared with repeated mould cleaning, damaged décor, poor air quality and long-term condensation problems.
We will always explain the cost before work begins.
