Is Professional Detection Worth It?

The Alternative: DIY Investigation

Potential costs of DIY approach:

Lifting floors to search: £200-500+ per room
Removing tiles: £100-300+ to reinstate
Time spent searching: Priceless
Damage if wrong area investigated: Variable
Water damage while searching: Ongoing

Professional Detection Saves Money By:

Pinpointing exact location
Minimising disruption and damage
Faster resolution
Preventing secondary damage
Providing evidence for insurance

Real Example:

“We suspected a leak under our kitchen but weren’t sure where. Professional detection cost £275 and found it precisely. Alternative was lifting the entire floor at £2,000+. Detection paid for itself ten times over.”

Questions to Ask Before Booking

Is there a callout fee? (Should be clear upfront)
What’s included in the price? (Get written confirmation)
What if you can’t find the leak? (Good companies won’t charge full price)
Do you provide a written report? (Important for insurance)
Are repairs included or separate? (Understand total potential cost)
What qualifications do your technicians have? (Look for certifications)
Is there a guarantee on your work? (Reputable companies offer this)

Insurance Considerations

What Home Insurance Covers:

Trace and access: Finding the leak (often covered)
Damage repair: Fixing damage caused by leak (usually covered)
Leak repair itself: The plumbing fix (often NOT covered)

Getting the Best Insurance Outcome:

Report the leak promptly
Get professional detection (provides documentation)
Keep all receipts and reports
Take photos before any work
Check your policy excess

Emergency vs Scheduled Pricing

Emergency Callout (Same day/24hr):

Premium of 50-100% common
Worth it for active, significant leaks
Prevents further water damage

Scheduled Survey (Within 1-3 days):

Standard pricing
Suitable for suspected slow leaks
Book sooner rather than later

When to Call Emergency:

Water visibly flowing
