Damp and Mould Services in Sussex
Professional Damp Surveys, Mould Treatment & Ventilation Solutions for Homes, Businesses & Housing Providers
Damp, condensation and mould can cause significant damage to a property and create an uncomfortable and potentially unhealthy living environment.
At CDS Electrical, we provide professional Damp and Mould Services across East and West Sussex, working with homeowners, landlords, housing associations, local authorities and commercial clients.
Our approach goes beyond simply treating visible mould. We investigate the potential cause of the problem, recommend appropriate remedial measures and provide solutions designed to help prevent the problem from returning.
From an individual home to a larger programme across multiple properties, our Damp and Mould Services provide a joined-up approach:
Survey • Diagnose • Treat • Ventilate • Maintain
Our services include:
Damp surveys
Damp surveys
Ventilation servicing & maintenance
Ventilation installation
Damp Surveys
Find the cause before treating the symptom.
If you have signs of damp, mould or excessive condensation, establishing the underlying cause is an important first step.
Our damp surveys provide a professional assessment of the property, helping to identify areas of concern, potential moisture sources and factors that may be contributing to the problem.
Depending on the property and circumstances, our assessment can include:
Visible damp, mould and moisture damage
Condensation and excessive humidity
Existing ventilation and extraction
Airflow throughout the property
Potential sources of water or moisture ingress
Performance of existing ventilation systems
Areas particularly susceptible to moisture, including kitchens and bathrooms
Following the survey, we can recommend appropriate remedial measures and, where required, undertake the necessary works as part of our complete Damp and Mould Services.
Don't just cover mould. Deal with the conditions allowing it to grow.
Visible mould should not simply be painted over. CDS provides professional mould treatment to affected areas while also investigating the conditions that may have allowed mould to develop.
Our Damp and Mould Services can include the treatment and removal of visible mould using appropriate specialist products and processes, alongside recommendations for addressing contributing factors.
Where excessive humidity, condensation or inadequate ventilation is contributing to mould growth, we can recommend and install appropriate ventilation improvements designed to reduce moisture levels and help prevent the problem from recurring.
Professional Mould Treatment
Improve airflow. Control moisture. Protect the property.
Good ventilation plays an important role in controlling moisture and maintaining a healthier indoor environment.
Everyday activities such as cooking, showering, washing and drying clothes, and even breathing, introduce moisture into the air. Without adequate ventilation, this moisture can accumulate and contribute to condensation, damp and mould growth.
As part of our Damp and Mould Services, CDS can assess your existing ventilation and recommend appropriate solutions to improve airflow and moisture control.
We provide ventilation solutions for:
Private homes
Rental properties
Social housing
HMOs and managed accommodation
Commercial properties
Public-sector buildings
Whether ventilation is required following a damp survey, as part of remedial works, during a refurbishment or to replace an inadequate existing system, our team can recommend a solution appropriate for the property.
Ventilation Installation
Ventilation Servicing & Maintenance
Installation is only the beginning.
Ventilation systems need regular care to continue operating effectively. Over time, fans, filters, vents and ductwork can become dirty, obstructed or less effective, reducing airflow and system performance.
Regular servicing can help maintain the performance, efficiency and lifespan of ventilation equipment. Servicing may also be required in accordance with manufacturer instructions to maintain the manufacturer's warranty.
Depending on the ventilation system, our maintenance can include:
System inspections
Cleaning of fans, vents and components
Filter inspection, cleaning or replacement
Airflow and performance checks
Inspection of accessible ductwork
Identification of faults or deterioration
Recommendations for repairs or improvements
Service records where applicable
For landlords, housing associations and property managers, we can also provide planned servicing and maintenance programmes across multiple properties.
Not every damp patch has the same cause.
Condensation is particularly common where moisture levels are high and ventilation is inadequate. However, damp and moisture can also be associated with water ingress, plumbing leaks, building defects or other underlying issues.
Common warning signs include:
Black mould around windows, walls or ceilings
Persistent condensation on windows
Damp or discoloured patches
Peeling or bubbling paint
Musty smells
Excessive moisture in bathrooms and kitchens
Mould behind furniture or inside cupboards
Mould that repeatedly returns after cleaning or decorating
Treating the wrong problem can result in unnecessary work while leaving the underlying cause unresolved. That’s why our Damp and Mould Services begin with investigation and diagnosis rather than assumption.
Is It Damp or Condensation?
Supporting Landlords & Housing Providers
CDS has extensive experience working within occupied properties on behalf of local authorities, housing associations, landlords and property managers.
We understand that reports of damp and mould need to be managed professionally, sensitively and efficiently, particularly where residents may be vulnerable or an issue has been ongoing.
Our Damp and Mould Services give housing providers a clear route from the initial report through to remedial works and ongoing prevention:
Survey
Diagnose
Report
Remediate
Prevent
Rather than coordinating several different contractors, clients can use CDS for damp assessment, mould treatment, ventilation installation and ongoing ventilation servicing and maintenance.
Supporting Social Landlords with Awaab's Law
Awaab's Law has introduced statutory requirements for social landlords in England to investigate and address certain hazards within prescribed timescales.
The first phase came into force on 27 October 2025 and includes significant damp and mould hazards. Under the current requirements, social landlords must investigate potential significant damp and mould hazards within 10 working days of becoming aware of them and provide the tenant with a written summary within 3 working days of the investigation concluding.
Where an investigation identifies a significant hazard, relevant safety work must generally be completed within 5 working days of the investigation concluding. Emergency hazards are subject to a much shorter timeframe, requiring landlords to investigate and take action to make the property safe within 24 hours.
CDS understands the importance of a prompt, properly documented and solution-focused response to reports of damp and mould.
We can support local authorities, housing associations and other social housing providers with:
Damp and mould surveys and investigations
Identification of potential causes and contributing factors
Assessment of existing ventilation and extraction
Recommendations for remedial measures
Professional mould treatment
Installation of new or improved ventilation
Servicing and maintenance of existing ventilation
Clear reporting and photographic evidence
Coordinated appointments within occupied properties
Planned programmes across multiple properties
Our Damp and Mould Services can form part of a social landlord's wider processes for responding to damp and mould and supporting their responsibilities under Awaab's Law.
