Leak detection
Methodical investigation of concealed and intermittent leaks using proportionate testing and diagnostic equipment.
Specialist leak detection across the North West
Finding the source.
Protecting your property.
Professional leak detection, trace and access, damp investigation and building diagnostics—with clear evidence and practical next steps.
Controlled trace & access Clear written reporting £10m public liability cover
Damp investigation & specialist services
Specialist investigation.
Straightforward answers.
Every property behaves differently. We investigate the evidence in context, distinguish between likely causes and explain what should happen next.
Trace & access
Controlled, minimal opening-up to locate the defect, document the cause and help plan the right repair.
Damp investigation
Evidence-led diagnosis of condensation, atmospheric moisture, penetrating damp and water ingress.
Building diagnostics
Clear findings for property managers, landlords and residents, supported by readings, photographs and practical recommendations.
Plumbing diagnostics
Investigation of domestic supplies, wastes, soil stacks, overflows, valves and water-related building defects.
Roof & rainwater ingress
Inspection of roof membranes, outlets, gutters, flashings and high-level defects linked to rainfall.
Out-of-hours response
Responsive support for urgent leaks and water-related incidents when management companies and residents need practical help outside normal hours.
Flat-to-flat leak specialists
Leak detection for flats and high-rise developments.
Apex specialises in investigating flat-to-flat leaks within apartment blocks and high-rise properties. Water can travel through floors, service risers, wall cavities and structural openings before becoming visible, so the point of damage is not always the source. We assess the pattern across the affected apartments and follow the evidence to identify the most likely route and cause.
Our investigations can include bathrooms, kitchens, internal plumbing, waste and soil systems, communal services, balconies, roofs and rainwater drainage. We coordinate access between residents and property managers, use controlled opening-up where necessary and provide clear photographic findings and practical recommendations for repair, monitoring or further access.

Soil stack replacement specialists
Soil stack replacement in high-rise blocks.
Apex specialises in soil stack replacement within high-rise, multi-occupancy apartment blocks. We investigate leaking, damaged or poorly configured soil stack sections, identify the extent of the defect and plan replacement work around residents, access restrictions and the needs of the wider building.
Works can include replacing damaged sections, branches, pan connectors and associated joints, with access and reinstatement coordinated where opening-up is required. We work with property managers and site teams to plan isolations, protect occupied areas and carry out appropriate testing before the system is returned to service.

Building diagnostics & property manager assistance
A specialist contact for building management companies.
Apex provides building management companies, managing agents and property managers with a reliable specialist contact for leaks, water ingress and damp issues across managed developments. We can coordinate access with residents and site teams, investigate affected apartments and communal areas and keep the property manager fully updated throughout.
Our reports set out what was inspected, the evidence found, the likely cause, any limitations and the recommended next steps. When further access, repairs, drying equipment or continued monitoring are required, we help to form a proportionate plan supported by clear photographs and practical information for your records and contractor follow-up.
HIGH-LEVEL ACCESSSafer first-look surveys
Roof drone surveys
See the roof before committing to costly access.
Our lightweight drone can capture detailed images of roofs and high-level elevations where a ground inspection cannot provide a reliable view.
- Flat and pitched roof coverings
- Gutters, outlets, flashings and parapets
- Chimneys, elevations and difficult junctions
- Photographic evidence for reports and quotations
Practical and responsible
Surveys are subject to site conditions, weather, access, privacy and a safe, lawful flight plan. A drone survey provides a visual inspection; we will explain when closer access or testing is still required.
MEWP & cherry picker access
Professional access to high-level building defects.
Apex is competent in the use of Mobile Elevating Work Platforms (MEWPs), including boom lifts, commonly known as cherry pickers. This gives us the ability to carry out close-range inspections and targeted access at height, including roofs, gutters, outlets, parapets, elevations, rainwater systems and difficult junctions.
MEWP access is planned around the building, ground conditions, machine reach, weather, exclusion zones and the protection of residents and the public. Where suitable, it can provide a practical alternative to scaffolding for investigation and selected works, allowing defects to be assessed directly and supported by clear photographic evidence.

Policies, procedures & site safety
A structured approach to safe, accountable work.
Apex works to documented company policies and procedures covering health and safety, environmental responsibilities, risk assessment, lone working, working at height, ladder and harness use, data protection and equal opportunities. Before work begins, we consider the site, access arrangements, occupants, public areas and the controls appropriate to the proposed task.
We carry out proportionate site safety assessments and prepare task-appropriate risk assessments and method statements where required. Competence is maintained through continued training, practical experience and regular reviews of our working methods, helping us to deliver work that is properly planned, responsibly managed and suited to the building and scope.

How we work
A disciplined route to the source.
We avoid assumptions. Findings are based on the pattern, construction, conditions and test results available on the day.
Listen
We establish the history of the problem, the affected areas and when it occurs.
Investigate
We inspect methodically and select the safest, least disruptive tests.
Evidence
We record relevant readings, test results, photographs and limitations.
Report
You receive a clear explanation of the likely cause and the recommended next step.
