Advice before products
If PIV is not the right solution for your property, we will tell you.Wet windows and persistent condensation can point to poor ventilation
Every property is different. Recurring moisture, mould around windows and stale or humid air can have more than one cause, so the property and symptoms need to be considered before recommending a system.
Where PIV is suitable, we install genuine Nuaire Drimaster ECO systems that provide whole-home fresh, filtered air. Where a loft is unavailable or unsuitable, a wall-mounted alternative may be considered.
