The Urgent Problem

The UK residential sector is facing a widespread damp and mould crisis affecting over 6.5million homes. A key factor which is exacerbating this issue is misfitted wall insulation which can trap moisture inside properties rather than preventing it, Leading to increased dampness and mould growth.

Poor installation and inadequate ventilation in older buildings have escalated these problems, causing significant structural damage and health risks. With homeowners suffering from respiratory and cardiovascular conditions worsened by these damp environments which intern places huge financial strain on the NHS.

The Damp and Mould Crisis

The United Kingdom faces an additional problem as government figures from 2023-2024 indicate that 1.3 million dwellings in England(about 5% of the total housing stock) had damp problems in one or more rooms. The problem affects both houses and leasehold flats across the UK, with social housing and housing association properties frequently reporting complaints related to damp and mould

Damp and mould damage properties and seriously impact health by triggering respiratory and cardiovascular health issues. These increased health diagnosis’s place significant strain on the NHS. Vulnerable groups such as children, the elderly, and low income families are disproportionally affected. Immediate coordinated action is essential to improve housing conditions, safeguard public health and reduce healthcare pressures caused by this growing crisis.

Not Just about Property!

Damp and mould are not just surface issues; they have serious health, financial, and social implications. The NHS spends an estimated £1.4 billion annually treating respiratory illnesses linked to damp environments. Furthermore, structural damage caused by moisture leads to costly repairs and increased energy bills as homes become harder to heat efficiently.

Black mould is far more than an eyesore – it’s a serious health risk. Mould releases mycotoxins that can trigger or worsen conditions such as asthma, sinus infections, eczema, coughing, respiratory disease and cardiovascular conditions.
For children, the elderly, and those with existing health concerns, a mould-infested home can quickly become a health crisis. The spores may be invisible, but their impact can linger long after the visual signs are wiped away.

Key Problems Moisture Causes

Mould poses serious health risks to residents, triggering severe respiratory issues like asthma attacks, wheezing, coughing, bronchitis, and chest infections - especially harmful for children, the elderly, and asthmatics.
It causes allergic reactions such as runny nose, sneezing, itchy/watery eyes, skin rashes, and sinusitis, while irritating eyes, nose, throat, lungs with burning, soreness, and phlegm, leading to fatigue, headaches, and "brain fog".
Mould heightens infection risks like aspergillosis or fungal pneumonia in immunocompromised or chronic lung patients, cardiovascular disease and worsens conditions like COPD and allergies, with mycotoxins sparking inflammation, immune changes, and even mental health declines.

Key Problems Moisture Causes

Structurally, mould destroys plaster, paint, and wallpaper through staining, bubbling, and flaking from trapped moisture, while rotting wooden frames, joists, and flooring as damp spreads.
It weakens walls, causing cracks from ongoing saturation and expansion/contraction, promotes pests like dust mites and rodents. This could result in failed surveys along with failed insurance and mortgage applications.

These issues rarely resolve on their own – professional diagnosis and ventilation are essential for lasting results.

What is the cost of the PIV and installation?

We offer a fixed price national supply and install service for £895.00 (inc VAT)

How much does the PIV unit cost to run?

The PIV unit sits in the loft, either hanging from a joist or attached to joists with adjustable anti vibration feet. It has a circular diffuser that is installed on the landing ceiling (white, around the size of a dinner plate).

What Our Client Says

Real Experiences, Real Impact

J Potter Homeowner

Absolutely delighted with our new DRI-ECO-HC ventilation system. Worked straight away, no condensation in wardrobes and walls dry. Struggled for 2 years trying to solve this problem.

M Gregory Homeowner

Just wanted to say what an amazing difference fitting your Drimaster PIV units has made to our house. Read about these units on the internet after researching how to deal with black mould and condensation on our windows. We’ve lived in our double glazed, cavity filled bungalow for 4 years and despair at the mould that appears every autumnal and winter. I found it hard to believe that such a simple solution would resolve the problem. I can’t believe the difference in condensation in less than 24 hours.

Michelle Homeowner

This really works. We suffered condensation & damp for 20 years before we installed a Nuaire Drimaster unit. It's been fitted now for 5 years & after the first 3 weeks we haven't suffered condensation or damp since. Thanks Nuaire
