Our services
Drone building inspection services
Thermal and visual aerial inspections for roofs, facades, and hard-to-access building areas across the Midlands and South East. Each service is explained in plain terms — what it is, who it is for, and exactly what you receive.
What we provide
Calibre Props carries out professional drone-based building inspections and aerial data capture. We collect thermal and visual imagery of roofs, facades, and hard-to-access building areas, and deliver it in an organised, useful format.
We work alongside surveyors, consultants, and facilities teams — providing the aerial data they need to carry out assessments, plan maintenance, and support reporting. The focus is on collecting clear, useful inspection data, not on making claims we cannot support.
Roof Inspections
What it is
Aerial inspection of flat roofs, pitched roofs, profiled metal roof systems, and associated drainage details using high-resolution visual imagery.
Who it is for
Facilities managers, housing associations, commercial property owners, surveyors, and estate teams managing large or complex roof areas.
Typical use cases
- Initial condition overview before appointing a surveyor
- Post-storm or post-incident condition checks
- Regular condition monitoring across an estate
- Pre-purchase or pre-sale condition evidence
What the client receives
- High-resolution visual imagery of roof surfaces
- Systematic coverage of the full roof area
- Organised imagery datasets ready for review
- Marked-up imagery highlighting areas of concern if agreed
Scope note: Visual aerial imagery supports condition assessment but does not replace a qualified surveyor's report. We collect the data; interpretation and formal condition reporting should be carried out by an appropriate professional.
Thermal Building Inspections
What it is
Thermal imaging surveys using a drone-mounted thermal camera to collect infrared imagery of building surfaces. Thermal imagery can highlight areas that may warrant further investigation for moisture, insulation gaps, or heat loss.
Who it is for
Energy managers, maintenance planners, surveyors, facilities managers, and building owners seeking to understand potential heat loss or moisture-related concerns.
Typical use cases
- Identifying areas of potential moisture ingress or damp for further investigation
- Supporting energy and heat loss assessments
- Condition monitoring of flat roof systems
- Pre-maintenance planning to prioritise areas of concern
What the client receives
- Thermal imagery of building surfaces
- High-resolution visual imagery for reference
- Organised thermal and visual datasets
- Annotation of areas of thermal anomaly if agreed
Scope note: Thermal imagery can help identify signs of potential issues but is not a definitive diagnosis. Thermal anomalies should be investigated further by an appropriate professional. Results depend on weather conditions, building use, and the timing of the survey.
Facade Inspections
What it is
Close-range aerial inspection of building facades, external walls, cladding systems, render, brick, glazing, and fixings — collected safely without scaffolding as a first step.
Who it is for
Commercial property owners, asset managers, housing providers, surveyors, and consultants requiring close-range condition imagery of building elevations.
Typical use cases
- External wall and cladding condition assessment
- High-level facade details that are difficult to access safely
- Pre-scaffold or pre-rope-access planning to target areas of concern
- Evidence collection for insurance, lease, or transaction purposes
What the client receives
- High-resolution close-range imagery of facade elements
- Coverage of high-level details including fixings, sills, and movement joints
- Organised image dataset referenced to elevation or building section
- Marked-up imagery of visible defects if agreed
Scope note: Drone imagery provides useful visual evidence but does not replace physical inspection for structural or safety-critical assessments. We help identify areas that may require closer investigation.
Building Condition Support Inspections
What it is
Aerial data capture to support broader building condition assessments carried out by surveyors, consultants, or estates teams. We collect the aerial imagery; your team or appointed professional interprets it.
Who it is for
Surveyors, consultants, healthcare estates teams, local authority estates, and anyone carrying out formal condition assessments who needs aerial imagery to support their work.
Typical use cases
- Supporting a surveyor or consultant with aerial imagery of areas they cannot safely access
- Providing condition evidence for scheduled maintenance programmes
- Capturing building condition at a point in time for records
- Supplementing ground-level surveys with aerial perspective
What the client receives
- Aerial visual and thermal imagery to agreed scope
- Well-organised datasets suitable for surveyor review
- Coverage of agreed building elements or areas
- Report-ready imagery formatted as required
Scope note: We work alongside your appointed professionals rather than replacing them. We capture the aerial data; formal assessment and reporting remains with the appropriate qualified individual.
Hard-to-Access Asset Inspections
What it is
Drone inspection of building elements and assets that are difficult, costly, or hazardous to access using conventional methods — parapets, roof edges, high-level fixings, plant decks, and similar areas.
Who it is for
Facilities managers, estates teams, surveyors, contractors, and building owners who need condition information from areas that are impractical to access without significant cost or disruption.
Typical use cases
- Initial condition check of high-level elements before committing to access equipment
- Inspection of assets where rope access or scaffolding would be disproportionate
- Monitoring of areas with restricted access during operations
- Post-construction or post-repair verification of high-level elements
What the client receives
- High-resolution imagery of the specific hard-to-access areas
- Close-range inspection imagery where safe and appropriate
- Organised dataset for review and record
Scope note: Drone access reduces the need for early-stage access equipment but does not eliminate the need for physical access where confirmed defects require repair or detailed investigation.
Inspection Imagery and Reporting Support
What it is
Organised, high-resolution visual and thermal imagery datasets delivered in a clear format, ready for use in condition reports, maintenance records, or client-facing documentation.
Who it is for
Surveyors and consultants who need organised aerial imagery to support reports; property managers and estates teams maintaining condition records.
Typical use cases
- Providing imagery for inclusion in formal condition or dilapidations reports
- Building a condition record for an asset at a point in time
- Supporting property management reports with aerial evidence
- Creating a maintenance reference dataset for ongoing use
What the client receives
- Full-resolution imagery organised by area, elevation, or building element
- Thermal imagery alongside visual for thermal survey scopes
- Annotated imagery with location references if required
- Dataset delivered in agreed format for direct use in reports or records
Scope note: Imagery is collected and organised to support your reporting process. We can agree the format and referencing approach in advance to make integration into your reports as straightforward as possible.
Deliverables
The outputs we can provide depend on the scope agreed for each inspection. The following are the types of deliverables we typically offer. We only promise deliverables we can consistently provide.
