New-build homes in Prestwich and across Manchester are designed to be energy-efficient and airtight — great for heat retention, but not always great for ventilation.
Many homeowners are surprised to experience condensation, wet windows and mould even in brand-new properties.
One of the most effective ways to balance humidity in a modern airtight home is with a Positive Input Ventilation (PIV) system.
At Weather Wise Solutions Limited, we install PIV systems across Greater Manchester to help homeowners create a healthier, drier and more comfortable indoor environment.
🏠 Why New-Build Homes Trap Humidity
New-builds are built to higher insulation and air-tightness standards than older housing stock. While this reduces heat loss, it also means moisture has nowhere to escape.
Common effects in Prestwich new-build homes include:
-
morning condensation on windows
-
mould behind furniture
-
damp corners
-
musty smells
-
condensation in bedrooms
-
persistent humidity even with heating on
Humidity rises from everyday activities:
-
breathing overnight
-
cooking
-
showers
-
drying clothes indoors
Without continuous ventilation, moisture accumulates.
🌬️ How a PIV System Works in a New-Build
PIV introduces filtered, fresh air into the home at a continuous, gentle rate.
It works by:
-
reducing humidity
-
diluting stale indoor air
-
pushing moisture-laden air out through natural leakage paths
-
improving overall air movement
In a sealed new-build, PIV restores the ventilation the property lacks.
🌀 Benefits of PIV in New-Build Homes
1️⃣ Stops Condensation & Wet Windows
Bedroom humidity falls, reducing morning condensation dramatically.
2️⃣ Reduces Mould Growth
By stabilising moisture levels, mould cannot thrive.
3️⃣ Creates a Fresher Indoor Environment
Filtered air dilutes odours, mustiness and pollutants.
4️⃣ Energy Efficient
PIV units use very little electricity — often less than a standard lightbulb.
5️⃣ Works Silently in the Background
Once installed, the system requires minimal maintenance.
6️⃣ Supported by Mechanical Extraction
In bathrooms and kitchens, PIV works best alongside DMEV continuous extract fans.
🧭 When PIV Is the Right Solution (and When It Isn’t)
✔ Ideal For:
-
airtight new-build homes
-
properties with persistent bedroom condensation
-
high humidity levels overnight
-
homes where trickle vents are closed or insufficient
❌ Not Ideal If:
-
the property has active penetrating damp
-
rising damp or DPC bridging is present
In these cases, structural defects must be corrected first.
