Leak Detection & Plumbing Repair

Not every plumbing leak is easy to find. A hidden leak can waste water, cause damage and become more difficult to repair if left unnoticed. Mastco Plumbing provides leak detection and plumbing repair services to help identify the source of the problem and get your plumbing back in working order.

Could You Have a Plumbing Leak?

Some plumbing leaks are obvious, while others can stay hidden behind walls, under floors or underground. Knowing the warning signs can help you catch a leak before it becomes a larger problem.

Unexpectedly High Water Bill

A sudden increase in your water bill without a change in usage can be a sign that water is escaping somewhere in your plumbing system.

Sound of Running Water

Hearing water running when your fixtures are turned off can indicate a hidden leak.

Water Stains or Discoloration

Brown, yellow or damp spots on walls, ceilings or floors can indicate water is leaking behind or beneath the surface.

Damp or Wet Areas

Unexplained moisture around fixtures, walls, floors or your yard may indicate a plumbing leak.

Low Water Pressure

A sudden or unexplained drop in water pressure can sometimes be associated with a leak or another plumbing issue.

Mold or Musty Odors

Persistent musty smells or unexplained mold growth can indicate moisture where it shouldn't be.

Think You May Have a Plumbing Leak?

Don't ignore the warning signs. Mastco Plumbing can help identify where the water is coming from and determine what needs to be done to repair the problem.

How Do Plumbers Find a Plumbing Leak?

Finding a hidden leak isn't always as simple as following the water. Our plumbers evaluate the symptoms and use appropriate diagnostic methods to help locate the source without unnecessary disruption to your home.

Inspect the Plumbing System

We start by evaluating the affected areas and looking for visible signs that can help point us toward the source of the leak.

Use Leak Detection Methods

Depending on the situation, we may use specialized leak detection equipment and other diagnostic methods to help locate hidden leaks.

Identify the Source

Once we've narrowed down the location, we'll explain what we've found and discuss the appropriate repair options.

What Causes Plumbing Leaks?

Plumbing leaks can happen for many reasons. Some develop gradually as pipes and connections age, while others can happen suddenly because of damage or changes in the plumbing system.

Aging or Corroded Pipes

Older pipes can deteriorate over time, eventually developing cracks, weak spots or leaks.

Loose or Damaged Connections

Fittings, valves and other connections can loosen or become damaged, allowing water to escape.

High Water Pressure

Excessive water pressure can put additional stress on pipes, fixtures and plumbing connections.

Shifting or Damaged Pipes

Changes in the soil, movement of the structure or other factors can cause pipes to shift, crack or separate.

A leak doesn't always have an obvious cause or appear where the actual problem is located. That's why finding the source is an important part of making the right repair.

What Happens If a Plumbing Leak Is Left Unrepaired?

Even a small leak can become a bigger problem over time. Water that continues to escape can damage materials around your home and potentially lead to more extensive plumbing repairs.

Water Damage

Continued moisture can damage flooring, walls, ceilings, cabinets and other areas of your home.

Mold & Moisture Issues

Persistent moisture can create conditions where mold and other moisture-related problems can develop.

Higher Water Bills

A hidden leak can waste water continuously, increasing your water usage and utility costs.

More Extensive Repairs

The longer a leak continues, the more opportunity there is for surrounding materials and plumbing components to be affected.

If you suspect a leak, finding it early can help prevent unnecessary damage. Mastco Plumbing can help identify the source and explain your repair options.
