A leaking chimney is one of the most common masonry problems homeowners face, especially in Ohio’s climate. Water can enter through multiple points, and once it does, it can spread into walls, ceilings, framing, and fireplaces. Many homeowners first notice signs like staining, odors, or moisture, but by the time these symptoms show up, the water has already found a path in.

At Level Up Masonry Restoration & Services, we don’t just seal or temporarily patch leaks—we find the source of the intrusion and repair the chimney correctly so the problem does not return. Based in Pataskala, OH, we provide trusted, long-lasting chimney leak repair throughout Central Ohio.

What Usually Causes a Chimney to Leak?

A chimney is exposed to all weather conditions—rain, snow, heat, freezing, and wind. Over time, moisture and temperature changes wear down brick, mortar, and protective surfaces. Once any part of the chimney weakens or cracks, water follows the path of least resistance and begins entering the home.

Common causes of chimney leaks include:

  • Cracked or Deteriorated Chimney Crowns
  • Worn or Missing Mortar Joints
  • Porous or Spalling Brick
  • Improper or Damaged Flashing Where the Roof Meets the Chimney
  • Missing or Inadequate Chimney Caps
  • Previous Repairs Using Incorrect Materials

Identifying where the leak is coming from is the most important part—because different causes require different repair methods.

How We Find and Fix Chimney Leaks the Right Way

We begin with a full chimney evaluation so we can determine exactly how and where water is getting in. We do not rely on guesswork or temporary fixes.

Checking the Chimney Crown and Cap for Cracks

We inspect the crown for cracking, separation, and improper slope, and confirm the chimney cap is preventing direct rain entry.

Looking for Worn Mortar Joints or Porous Brick

Damaged mortar and water-absorbing brick allow moisture to move deep into the structure. We determine whether tuckpointing or brick replacement is needed.

Inspecting the Flashing Where Your Chimney Meets the Roof

Flashing failures are one of the most overlooked causes of chimney leaks. We confirm this transition is sealed and properly layered to prevent infiltration.

Tracing the Exact Path of Water Movement

We track moisture patterns to identify the true source, not just the visible symptoms.


Once the problem is understood, we repair the chimney using materials that match the existing structure and are appropriate for the home’s age and construction.

Why Fixing a Leaking Chimney Promptly Really Matters

Ignoring a leaking chimney can lead to:

  • Interior Drywall or Ceiling Damage
  • Roof Deck Rot
  • Mold or Mildew Issues
  • Brick Decay and Structural Weakening
  • Increased Repair Costs Over Time

Chimney leaks do not resolve themselves. They continue to worsen until addressed.

Frequently Asked Questions About Leaking Chimneys

  • What Are the Signs That My Chimney Is Leaking?

    Signs include staining on ceilings or walls, musty smells, dampness near fireplaces, or visible water entry during rain.

    No. Sealers and surface coatings are temporary solutions. We repair the source of the leak to prevent it from returning.

  • Can Weather and Freeze-Thaw Cycles Cause Chimney Damage?

    Yes. Freeze-thaw cycles push moisture deeper into masonry, causing cracks and deterioration.
