Creating Healthier, Safer Homes Through Effective Ventilation
Modern homes are designed to be more energy efficient than ever before. While this helps reduce heat loss and energy costs, it can also trap moisture, pollutants, and stale air within the property. Without adequate ventilation, this can lead to condensation, mould growth, poor indoor air quality, and an unhealthy living environment.
At RTC, we provide professional domestic ventilation solutions that not only help prevent condensation and mould but also create healthier, safer homes for occupants. Our experienced team designs and installs systems that improve indoor air quality, control humidity levels, and ensure compliance with current Building Regulations.
Ventilation Is About More Than Preventing Mould
Many homeowners only consider ventilation when they start to see black mould appearing on walls, ceilings, or around windows. However, poor ventilation can affect far more than the appearance of a property.
Inadequate air movement can lead to:
- Excess condensation and dampness
- Mould and fungal growth
- Unpleasant odours
- Increased dust, allergens, and airborne pollutants
- Poor indoor air quality
- Potential health issues, particularly for children, the elderly, and those with respiratory conditions
A properly designed ventilation system continuously removes stale, moisture-laden air and replaces it with fresh, filtered air, helping to create a healthier and more comfortable living environment all year round.
Professional Ventilation Solutions from RTC
At RTC, we install, assess, maintain, and repair a wide range of domestic ventilation systems tailored to the specific needs of each property.
Our services include:
Positive Input Ventilation (PIV) Systems
PIV systems introduce fresh, filtered air into the home, gently diluting and displacing moisture-laden and stale air. They are highly effective in reducing condensation and mould problems while improving overall indoor air quality.
Mechanical Ventilation Systems
We install a variety of mechanical ventilation solutions designed to extract excess moisture and maintain healthy airflow throughout the property. These systems can be specified for individual rooms or whole-house applications depending on the building’s requirements.
MVHR Assessment, Testing and Repairs
Mechanical Ventilation with Heat Recovery (MVHR) systems play a vital role in many modern, energy-efficient homes. However, poorly commissioned, incorrectly balanced, or poorly maintained systems can significantly reduce performance and impact indoor air quality.
RTC can inspect, assess, test, diagnose, maintain, and repair existing MVHR systems to ensure they are operating efficiently and delivering the intended levels of ventilation and heat recovery. Whether you are experiencing performance issues, airflow concerns, compliance requirements, or occupant complaints, our team can provide expert support and practical solutions.

Qualified Ventilation Surveyors
Unlike many contractors who simply install equipment, RTC employs fully qualified CSDV (Certificated Specialist in Domestic Ventilation) surveyors who understand the complex relationship between ventilation, moisture movement, building fabric, energy efficiency, and occupant health.
Our surveyors carry out detailed assessments to identify the root causes of condensation, dampness, mould growth, and poor indoor air quality before recommending the most appropriate solution. This ensures that any ventilation measures are based on evidence and building science rather than a one-size-fits-all approach.
By combining qualified surveying expertise with practical installation experience, RTC delivers ventilation solutions that are effective, compliant, and designed to provide long-term benefits for both properties and their occupants.

Ventilation Service & Maintenance Packages
A ventilation system can only perform effectively if it is properly maintained. Over time, filters become clogged, airflow rates can fall out of balance, components can deteriorate, and systems may no longer deliver the level of ventilation required to protect the property and its occupants.
To help homeowners, landlords, housing providers, and property managers maintain healthy indoor environments, RTC offers tailored ventilation service and maintenance packages designed to keep systems operating safely, efficiently, and in compliance with current standards.
Our service packages can include:
- Routine ventilation inspections
- Performance testing and airflow verification
- Filter inspection, cleaning, and replacement
- PIV system servicing
- MVHR servicing, maintenance, and repairs
- Fault diagnosis and corrective works
- Compliance checks and reporting
- Advice on system optimisation and energy efficiency
- Ongoing planned preventative maintenance programmes
Regular servicing helps maximise system performance, prolong equipment life, reduce the risk of condensation and mould recurrence, and ensure occupants continue to benefit from good indoor air quality.
Whether you require a one-off inspection or a fully managed maintenance programme, RTC can provide a package tailored to your requirements.
