Fire Door Photography Best Practices

Good photography is essential to fire door inspection. Photos provide evidence that supports your findings, helps clients understand issues, and creates documentation that stands up to scrutiny.

Bad photos waste time, create doubt, and can undermine otherwise solid surveys.

This guide covers practical photography techniques for fire door surveyors.

Why Photos Matter

Evidence

Photos prove what you found:

• “The gap is excessive” is an opinion
• “The gap is excessive — here’s a photo showing my gauge at 6mm” is evidence

If your findings are ever questioned, photos are your defence.

Client Understanding

Many clients aren’t fire door experts. Photos help them see what you’re describing:

• “The intumescent seal is missing” is abstract
• A photo showing the empty groove makes it concrete

Photos bridge the gap between technical language and visual reality.

Regulatory Compliance

For higher-risk buildings under the Building Safety Act 2022, documentation requirements are significant. Photo evidence forms part of the building’s safety record and may be reviewed by building safety regulators.

Remediation Guidance

Contractors fixing defects need to understand what they’re dealing with:

• What’s the current condition?
• What exactly needs doing?
• What does “correct” look like nearby?

Photos help remediation contractors quote and work accurately.

Essential Shots

Every Door: Overview Photo

What to capture:

• Full door visible
• Door in closed position
• Surrounding frame visible
• Location identifiable if possible

Purpose:

• Proves you were at that door
• Shows general condition
• Provides context for detail shots
• Helps client identify which door

Defect Documentation

For each significant defect:

• Close-up showing the issue clearly
• Reference point if helpful (gap gauge, finger, etc.)
• Context showing where on door

Examples:

Defect	Photo Should Show
Excessive gap	Gap gauge inserted showing measurement
Missing seal	Empty groove where seal should be
Damaged door leaf	Extent and nature of damage
Faulty closer	Issue (leaking, damaged, wrong type)
Wrong hinges	Hinge type and count
Missing signage	Where sign should be (or damaged sign)

Certification Labels

When visible:

• Certification/plug labels
• Manufacturer identification
• Any markings indicating fire rating

These help verify the door specification and may be needed for future reference.

Camera Settings and Technique

Equipment

You don’t need professional camera equipment. A smartphone with a reasonable camera is fine for most survey work. What matters is technique.

Smartphone tips:

• Keep lens clean (wipe before each site)
• Use tap-to-focus on key detail
• Enable grid lines for composition
• Avoid digital zoom where possible

Lighting

Fire doors are often in corridors with variable lighting.

Good lighting practices:

• Use natural light where available
• Position yourself so light falls on subject
• Use phone torch for dark areas
• Avoid direct flash creating harsh shadows

Problematic lighting:

• Backlit doors (window behind) — move to side
• Very dark corridors — use auxiliary light
• Mixed lighting (daylight + fluorescent) — can create colour issues

Focus and Clarity

Blurry photos are useless. Ensure:

• Camera is steady (brace against body or wall)
• Subject is in focus (tap to focus on key area)
• Sufficient light for sharp capture
• Clean lens

Take an extra second to ensure the shot is clear. It saves time versus retaking later.

Composition

Include context: Don’t zoom in so tight that location is unclear. Include enough of the door/frame to show where the defect is.

Show scale: For size-relevant defects (gaps, damage extent), include a reference:

• Gap gauge showing measurement
• Your finger for general scale
• Known-size object

Avoid clutter: Frame the shot to focus on what matters. Corridor traffic, bins, and other distractions can obscure findings.

Common Defects: Photo Approaches

Gap Measurements

Best practice:

• Insert gap gauge at measurement point
• Position camera to show gauge reading clearly
• Include enough frame/door to show location

Common mistakes:

• Gauge not fully inserted
• Angle makes measurement hard to read
• Too zoomed out to see gauge
• Fingers obscuring view

Missing or Damaged Seals

Best practice:

• Show empty groove or damaged seal clearly
• Include section showing correct seal nearby (if available)
• Multiple shots if seal missing in multiple locations

Common mistakes:

• Shadow obscures groove
• Too zoomed out to see issue
• Not clear what’s missing

Damaged Door Leaves

Best practice:

• Overview showing extent of damage
• Close-up of damage detail
• Multiple angles if damage is complex

Common mistakes:

• Not capturing full extent
• Glare on surface obscuring damage
• No scale reference

Closer Issues

Best practice:

• Closer visible in frame
• Issue evident (leaking oil, damage, wrong type)
• For operational issues, consider short video

Common mistakes:

• Door obscuring closer
• Issue not clearly visible in still image

Hinge Problems

Best practice:

• All hinges visible (count confirmation)
• Close-up of problem hinge
• Fixing condition if relevant (missing screws)

Common mistakes:

• Only one hinge photographed
• Issue not clear from angle

Missing Signage

Best practice:

• Show both sides of door if sign missing
• Capture where sign should be (eye level on face)
• If sign present but incorrect, show the sign

Common mistakes:

• Photo doesn’t clearly show sign is absent
• No context to identify the door

Workflow Efficiency

Consistent Sequence

Develop a standard photo sequence:

1. Door overview (every door)
2. Label/certification (if visible)
3. Defect close-ups (if defects found)
4. Move to next door

Consistency speeds workflow and ensures nothing is missed.

Photo Management

On-site:

• Use survey app to link photos to doors
• Or establish clear naming/numbering system
• Review occasionally to check quality

Avoid:

• Hundreds of photos with no organisation
• Relying on time-stamps to sort later
• Photos in camera roll mixed with personal pictures

Quantity Balance

Too few photos:

• Insufficient evidence
• Gaps in documentation
• Difficult to write reports later

Too many photos:

• Wastes time on site
• Clutters reports
• Processing overhead

About right:

• Overview every door
• Key defects documented
• Enough detail to support findings
• Not excessive duplication

For a standard survey, expect 2-5 photos per door on average. Doors with no defects need only overview. Doors with multiple issues need more.

Post-Survey Processing

Review and Selection

After the survey:

• Review photos for quality
• Flag any that need retaking
• Match photos to door records
• Discard unusable duplicates

Enhancement (Sparingly)

Basic adjustments are reasonable:

• Brightness/contrast for visibility
• Cropping to focus on relevant area
• Rotation if camera was tilted

Do not:

• Edit out or add content
• Alter what the photo shows
• Over-process to the point of unreality

Photos are evidence. Editing to change what they show is dishonest.

Integration with Reports

Effective photo use in reports:

• Placed near relevant text
• Clear captions explaining what’s shown
• Sized appropriately (visible but not oversized)
• Referenced in findings

Poor photo use:

• Appendix of unlabelled photos
• Tiny thumbnails impossible to see
• Photos not connected to specific findings
• Massive files that bloat documents

Special Situations

Occupied Spaces

When surveying in occupied areas (residential flats, offices):

• Avoid capturing people without consent
• Be mindful of personal items visible
• Focus on the door, not the space behind
• Explain what you’re photographing if asked

Security-Sensitive Locations

Some sites restrict photography:

• Check before starting
• Understand what can/can’t be captured
• Get permission in writing if needed
• Respect restrictions (even if inconvenient)

Low-Light Environments

Plant rooms, basements, service areas:

• Use auxiliary lighting
• Multiple flash photos from different angles
• Note limitations in report if photo quality suffers

Equipment Recommendations

Smartphone Photography

For most surveyors, a smartphone is sufficient:

Pros:

• Always with you
• Good enough quality
• Easy integration with apps
• Quick sharing

Tips:

• Mid-range or better phone (older phones have poor cameras)
• Invest in a portable battery pack
• Consider a small clip-on light for dark areas
• Protective case for site conditions

Dedicated Cameras

Some surveyors prefer compact cameras:

Pros:

• Better low-light performance
• Optical zoom
• Separate from personal phone
• Larger batteries

Cons:

• Another device to carry
• Requires photo transfer step
• Additional cost

Photo Storage

Consider:

• Cloud backup enabled on phone
• Sufficient storage capacity
• Regular backup to PC/cloud
• Retention policy matching record requirements

Losing photos through device failure or storage limits is avoidable but happens.

Summary: Photo Checklist

Before site:

• Lens clean
