Signs You Might Have a Hidden Leak

Not all plumbing leaks announce themselves with puddles or the sound of dripping. Some are buried deep within your walls or under your foundation. These hidden issues can fester for months or even years if undetected. Here are some subtle (and not-so-subtle) signs that it’s time to call the experts:

• A sudden spike in your water bill without increased usage
  
  
• Warped flooring or unexplained wet spots
  
  
• Musty odors or signs of mold growth
  
  
• Hot spots on your floor (often a sign of a hot water slab leak)
  
  
• Reduced water pressure
  
  
• Constant sound of water running with no fixtures on
  
  

If you're experiencing any of these symptoms, don't delay. The longer a leak goes unnoticed, the greater the risk of structural damage, rot, and mold development.

Advanced Leak Detection Technology

At Thorough Plumbing, we pair years of plumbing expertise with state-of-the-art tools to pinpoint the source of your leak quickly and accurately—without tearing up your walls or flooring. Our non-invasive methods include:

• Acoustic leak detection: Sensitive listening devices can hear the faint sound of water escaping from pressurized pipes.
  
  
• Thermal imaging: Infrared cameras help detect temperature differences caused by leaking hot water lines.
  
  
• Pressure testing: Confirms the presence of leaks in various sections of your plumbing system.
  
  
• Moisture meters: Identify areas with hidden water intrusion.
  
  

This technology allows us to diagnose the issue with minimal disruption to your property and start repairs immediately.

Repairing the Problem with Precision

Once we’ve located the source of your leak, our expert plumbers will walk you through your options and carry out the repairs efficiently and with care. Whether it’s a pinhole in your copper pipe or a major slab leak beneath your foundation, we bring the right tools and the right mindset to solve the issue at its core.

Our repair services include:

• Pipe replacement or re-routing
