Poor ventilation is one of the most common causes of condensation, mould and poor indoor air quality in UK properties. When natural airflow is not enough, mechanical ventilation provides a controlled, long-term solution. DampMaster installs and advises on a range of mechanical ventilation systems, including positive input ventilation (PIV) units, high capacity extraction and single room heat recovery units, tailored to the property and the problem.

Every occupied property generates moisture from cooking, bathing, breathing and drying clothes. Without adequate ventilation, that moisture builds up on cold surfaces as condensation and creates the conditions for mould growth. Mechanical ventilation addresses the root cause by actively managing airflow and reducing excess humidity.
A PIV unit is one of the most effective and energy-efficient solutions for whole-house condensation control. Installed in the loft space or on an external wall, a PIV system gently introduces filtered, dry air into the property, creating a slight positive pressure that displaces humid, stale air through natural leakage points. PIV is widely recommended as a cost-effective way to reduce condensation, improve air quality and help prevent mould growth without the need for major building work.
We are Property Protection Specialists who understand the relationship between ventilation, moisture and building performance. Our surveyors are ABBE Level 3 qualified. We are Checkatrade approved and TrustMark registered.
We assess the property, identify the source of excess moisture and recommend the most appropriate ventilation solution. Our recommendations are based on what the property actually needs.

Bathrooms, kitchens and utility rooms are high-moisture zones where standard extractor fans may not be enough. High capacity extraction units are designed to remove larger volumes of humid air at source, reducing the moisture load before it spreads through the rest of the property.
A single room heat recovery unit provides continuous ventilation to an individual room while recovering heat from the outgoing air. Ideal for bedrooms, living rooms and spaces where condensation is persistent but whole-house ventilation is not required or practical.
We do not apply a one-size-fits-all fix. We treat each job with care and respect and aim to do it right first time, everytime.
Recommendations are based on survey findings, property type and the most appropriate treatment method.
Damp proofing work is backed by a guarantee where applicable.
Common signs of damp include tide marks or staining on walls, peeling paint or wallpaper, black mould, musty smells, and crumbling plaster or woodwork. You may also notice condensation on windows, cold or wet-feeling walls, or a general damp feeling in certain rooms, especially at ground level or in basements.
Damp can be caused by a range of issues, including rising damp from the ground, penetrating damp due to leaks or damaged masonry, condensation from excess moisture in the air, or even faulty gutters and drains. Our surveyors will assess your property to identify the exact cause and recommend the right solution.
Yes, especially if you’re seeing signs of damp or planning to buy a new property. A professional damp survey will help you understand the cause, severity, and best course of action. It’s the first step toward protecting your home (and your wallet) from long-term damage.
Costs can vary depending on the type of damp, the size of the affected area, and the treatment required. We carry out an initial damp survey so we can assess your property properly and provide a clear, fixed-price quote with no hidden fees.
Most treatments are completed within a few days, depending on the size of the job. We’ll always give you a clear timeline upfront, and we work hard to minimise disruption to your home.
In most cases, no. You can stay in your home while we carry out the work. If large areas need treatment or plastering, we’ll discuss this with you in advance so you can plan accordingly.
Yes, if plastering is part of the process, you’ll need to redecorate. We’ll leave your walls ready to paint or wallpaper once they’ve dried fully. We can also recommend trusted decorators in your area if needed.
Yes. All DampMaster surveyors are PCA-trained and experienced in identifying damp, timber, and other issues. Our technicians are fully trained, insured, and follow strict standards to ensure high-quality workmanship. Our surveyors also hold ABBE Level 3 in Damp, Mould and Condensation.
