PIV Installation in Brighton: A Long-Term Solution to Condensation

Written by Josh Jackson | Feb 5, 2026 8:28:19 AM

Across Brighton homes, condensation and damp are common issues that go far beyond steamed-up windows. Coastal air, seasonal temperature changes, and a mix of older properties and modern airtight upgrades all contribute to trapped moisture indoors. Over time, this leads to mould growth, damage to décor, and poor indoor air quality. For many households, the most effective solution is Positive Input Ventilation (PIV).

Why Condensation Happens in Homes

Daily activities like cooking, showering, and drying clothes release litres of moisture into the air. In properties with limited airflow, that moisture settles on cold surfaces such as windows, external walls, and ceiling corners. This is why many residents search for ways to reduce condensation in the home or find a lasting condensation solution in Brighton homes.

Short-term fixes like dehumidifiers can help temporarily, but they don’t provide the whole-house ventilation system needed to control humidity consistently. Without proper ventilation, mould often returns — leading homeowners to look for reliable mould and damp solutions in Brighton.

How Positive Input Ventilation (PIV) Works

A Positive Input Ventilation system is a fresh air ventilation system that gently introduces filtered air into the property, usually from the loft. This steady airflow dilutes and displaces stale, moisture-laden air, pushing it out through natural leakage points. Instead of humidity lingering, the home benefits from continuous air movement.

This approach helps to:

  • Reduce condensation in the home
  • Support damp prevention in homes
  • Limit the conditions that allow mould to grow
  • Improve overall indoor air quality

Homeowners often notice clearer windows, fewer musty smells, and a more comfortable environment within days. Modern PIV units are quiet, energy-efficient, and some include heaters to temper incoming air during colder months.

Why Professional PIV Installation Matters

Not all properties are the same. Brighton includes Victorian terraces, converted flats, and modern developments — each with different airflow patterns and insulation levels. For a loft-mounted ventilation unit like PIV to work effectively, it must be correctly sized, positioned, and commissioned.

This is where specialist expertise becomes essential. Poor installation can mean the system doesn’t deliver proper airflow, leaving condensation issues unresolved.
