Plumbing / Project guide

Building water leak investigation

Organize an investigation of an unexplained plumbing leak or recurring water loss. Describe the observations without guessing the source, then ask the provider to propose a sequence that protects occupants and documents what was established.

The decision this helps you make

What to aim for.

A recorded investigation with identified findings, remaining uncertainty and a clearly separated corrective-work proposal.

Start with the information below, then choose your property type for the access, operating and decision-making details that shape the project.

Define the scope.

  • List visible moisture, unusual water use or recurring symptoms by location and date.
  • Identify the shared systems and occupied areas the provider may need to investigate.
  • Ask how the provider will obtain approval before opening finishes or isolating equipment.

Put these records together.

  • Collect photographs, relevant water-use records and details of earlier leak repairs.
  • Supply available plumbing plans and identify recent work near the affected locations.
  • Provide access contacts for each controlled space and the building’s communication arrangements.

Choose your property type.

Ask for a comparable proposal.

  • Describe the initial investigation visit and the method for approving additional stages.
  • Separate locating work, temporary measures, repair and finish restoration in the quotation.
  • Ask how observations, tests and inaccessible areas will be recorded for the owner.

Understand what affects the cost.

Ask providers to price the same scope and explain the assumptions behind these items.

  • Whether the source can be reached through existing access or requires investigative openings.
  • The number of systems, suites or common spaces involved in tracing the issue.
  • The need for repeat visits, occupant coordination or specialist investigation alongside plumbing work.

Project: Building water leak investigation

Agree on the handover.

  • Keep the investigator’s findings, photographs and the locations of any temporary measures.
  • Record which potential sources were checked and which uncertainties still need attention.
  • Obtain a written repair scope and restoration responsibilities before authorizing the next stage.

Questions before you begin.

What should we do if water is actively damaging the property?

Use the property’s established urgent-response contacts and arrangements first. When requesting follow-up investigation, describe the actions already taken, affected areas and any immediate access or occupancy concerns.

Should we ask for a fixed repair price before the source is known?

Ask for a defined investigation stage and an approval process for the repair that follows. A useful proposal explains what can be priced now and what depends on the findings.

Continue planning.
