Chimney Leaking Water? Schedule Your Chimney Leak Inspection to Discover the Issue

A Chimney Leak Inspection, also known as Chimney Leak Testing, is a specialized process used to identify the source of water intrusion in masonry or prefabricated chimneys. Chimney leaks are a common problem for homeowners and, if left unaddressed, can cause significant structural damage, mold growth, and deterioration of the chimney components.

At Nexus Chimney Services, we perform comprehensive chimney leak inspections to locate the penetration points and provide effective repair recommendations. Our goal is to ensure your chimney remains watertight, protecting your home and fireplace from further damage.

Why Do Chimneys Leak?

Chimneys are constantly exposed to the elements, making them prone to water intrusion. Here are some common causes of chimney leaks:

For Masonry/Brick Chimneys

  • Cracked or Missing Mortar Joints: Deteriorated mortar allows water to seep into the brickwork.
  • Porous Bricks: Over time, bricks can absorb water if not properly sealed.
  • Damaged Chimney Crown: Cracks or gaps in the crown allow water to penetrate the top of the chimney.
  • Faulty Flashing: Improper or damaged flashing around the chimney base can lead to leaks where the chimney meets the roof.

For Prefabricated Chimneys

  • Leaky Chase Covers: Rusted or damaged chase covers allow water to enter the chimney structure.
  • Improper Seals Around Piping: Gaps where the vent pipe meets the chase cover can allow water intrusion.
  • Damaged Siding or Gaskets: Cracks in siding or failed gaskets can let water into the chimney housing.

Signs You Have a Chimney Leak

Water intrusion in your chimney often presents with these warning signs:

  • Staining or discoloration on the interior or exterior walls around the chimney.
  • Damp smells or visible water in the fireplace.
  • Cracked, spalling, or crumbling bricks or mortar.
  • Rust on the damper, firebox, or metal components of a prefabricated chimney.
  • Water pooling at the base of the chimney or on the hearth.

What Does a Chimney Leak Inspection Include?

At Nexus Chimney Services, our certified technicians perform a thorough inspection to identify the source of your chimney leak. Here’s what’s involved:

  1. Visual Assessment

We start by examining the chimney’s exterior, looking for cracks, gaps, or damaged components that could allow water intrusion. For masonry chimneys, we inspect the mortar joints, bricks, flashing, and crown and for a proper sized chimney cap. For prefabricated chimneys, we evaluate the chase cover, termination cap, siding boards, trim boards and caulking/sealed seams. In some cases, there are brick or stone veneer prefabricated chimney chases structures, so these need to be examined much like a masonry chimney.

  1. Water Testing

Using controlled water spray techniques, we test specific areas of the chimney to locate the exact penetration points. This step ensures no leak is overlooked.

  1. Interior Inspection

We inspect the interior of your chimney, including the firebox, flue liner, and damper, for signs of water damage, rusting, corrosion, mold growth or staining.

  1. Detailed Report/Estimate

After identifying the source(s) of the leak, we provide a detailed report or chimney leak repair estimate with effective recommendations tailored to your chimney’s needs. Say good-bye to your leaky chimney!
