Across Camberley—from family homes in Heatherside to flats around Frimley Road—homeowners are experiencing a sharp rise in condensation and mould-related problems. With modern insulation upgrades and tightly sealed double glazing becoming the norm, natural airflow has been drastically reduced.
Across Camberley—from family homes in Heatherside to flats around Frimley Road—homeowners are experiencing a sharp rise in condensation and mould-related problems. With modern insulation upgrades and tightly sealed double glazing becoming the norm, natural airflow has been drastically reduced.
As a result, damp conditions and poor indoor air quality are affecting everything from tenant satisfaction in rental properties to the long-term health of buildings. The solution many residents are turning to? Positive Input Ventilation (PIV).
This blog explains how PIV works, why it’s becoming a preferred choice for Camberley homeowners, and what to expect from a professional PIV installation with ClimateWorks.
Condensation happens when warm, moist air meets a cold surface—commonly seen on windows, walls, and bathroom mirrors. When homes are well insulated and sealed, moisture from everyday activities like cooking, showering, and even breathing has no way to escape. Over time, this can cause:
Ventilation is key to controlling moisture levels, but traditional extractor fans and window vents are often insufficient—especially in older homes that have been upgraded without a full ventilation strategy.
Positive Input Ventilation (PIV) is a whole-house ventilation system designed to reduce moisture, improve air quality, and reduce condensation.
It works by drawing in filtered air from the loft or outside and gently pushing it into the home via a single diffuser, typically installed on the upstairs landing. This creates a positive pressure environment that continuously replaces stale, humid air with fresh air—pushing the moist air out through natural leakage points.
A landlord contacted ClimateWorks after multiple tenants complained of damp and mould in a two-bedroom mid-terrace property.
Reported issues:
Solution:
Within 10 days, the tenant reported a noticeable improvement in air freshness, no more morning condensation, and the gradual disappearance of surface mould.
Camberley’s housing stock includes everything from 1930s semis to 2000s estates and modern apartments. Many of these properties have seen improvements like wall insulation, new windows, and air-tight doors—but no complementary ventilation upgrades.
Installing a PIV system is straightforward and typically completed within one day.
All work is carried out by our qualified engineers with minimal disruption and a clean finish.
While PIV systems are not mandatory, they contribute to overall compliance with the UK Building Regulations—specifically:
ClimateWorks always ensures installations meet current standards and can advise if upgrades to extract fans or vents are required.
ClimateWorks offers ongoing support for all PIV installations. While these systems require minimal maintenance, we recommend:
We also offer upgrades for older systems or replacements for faulty or underperforming units.
If your home in Camberley suffers from damp, poor air circulation, or window condensation, a PIV system may be the answer. ClimateWorks provides expert consultation, rapid installation, and reliable long-term performance.
