Water Leak Detection & Repair in Durham Region

Serving Pickering, Ajax, Whitby, Oshawa, Bowmanville & Surrounding Areas

A hidden or active plumbing leak can cause water damage if it isn't addressed. Caldwell Plumbing provides professional leak detection and repair to locate the source of the problem and determine the appropriate repair.

Signs You May Have a Hidden Plumbing Leak

Not every plumbing leak is easy to see. Changes in your water bill, pressure, walls, floors, or fixtures can indicate that water is escaping somewhere in the plumbing system.

Higher Water Bills

An unexplained increase in water use or your monthly water bill can be a sign of a leak, especially when your household or business usage hasn’t changed.

Low Water Pressure

A noticeable or unexpected drop in water pressure may indicate a plumbing problem. While low pressure can have several causes, a leaking pipe is one possibility that should be investigated.

Water Stains on Walls or Ceilings

Yellow, brown, or discoloured patches on ceilings and walls can indicate moisture from plumbing above or behind the affected area.

Musty or Damp Smells

Persistent musty smells can develop when moisture is collecting somewhere it shouldn’t. If the source isn’t obvious, a hidden plumbing leak may need to be ruled out.

Mould or Mildew

Mould or mildew that repeatedly appears around walls, ceilings, cabinets, or plumbing fixtures may be associated with excess moisture from a leak.

Damp Floors or Walls

Wet spots, soft drywall, peeling paint, warped flooring, or unexplained damp areas can indicate water leaking from a nearby pipe, fixture, or connection.

Running Toilets

A toilet that continues running after flushing can waste a significant amount of water. Worn or malfunctioning components are common causes and can often be repaired.

Common Plumbing Leaks We Find & Repair

Plumbing leaks can develop throughout a home or commercial property, from visible fixture leaks to hidden problems inside walls, ceilings, and other areas.
Common problems we help with include:

If the source of the water isn’t obvious, our plumbers can inspect the affected area and determine where the leak is coming from before recommending the appropriate plumbing repairs.

Our Leak Detection & Repair Process

Our plumbers work to identify where the water is coming from, determine what is causing the leak, and recommend the appropriate repair based on what we find.

1. Inspect the Plumbing Problem

We begin by checking the affected area, nearby plumbing fixtures, and other signs that can help narrow down where the leak may be coming from.

2. Locate Hidden Leaks

When the source isn’t visible, leak detection tools and diagnostic methods can help investigate plumbing behind walls, beneath floors, or in other difficult-to-access areas without unnecessary disruption.

3. Diagnose the Cause

Once we locate the leak, we assess the affected pipe, fixture, connection, or plumbing component to determine what failed and why.

4. Repair the Leak

Depending on the problem, the repair may involve fixing or replacing a damaged pipe, fitting, valve, fixture, seal, or other plumbing component.

5. Recommend Next Steps

If we identify corrosion, aging plumbing, pressure concerns, or another issue that could contribute to future leaks, we’ll explain what we found and discuss any recommended repairs or preventative steps.
