A leaky chimney may not seem like a big deal—until you notice stains on your walls, a musty smell near your fireplace, or even puddles of water on your hearth. Water intrusion is one of the most common and destructive issues chimneys face, especially in a climate like Rhode Island’s, where snow, rain, and freeze-thaw cycles are frequent.
At Local Chimney Services , we help homeowners diagnose and repair chimney leaks before they lead to serious structural damage. If you suspect your chimney is leaking, it’s important to act quickly. This guide covers how to identify leaks, what causes them, and how we fix them to protect your home.
Chimneys are exposed to the elements 24/7. Over time, rain, snow, and melting ice can work their way into cracks and weak points. While masonry is strong, it’s also porous. Without proper protection, even small amounts of water can penetrate the surface and cause damage from the inside out.
Common causes of chimney leaks include:
The crown is the concrete or masonry slab at the very top of the chimney. It’s designed to keep water from entering the chimney chase. When it cracks or deteriorates, water can seep in and cause internal damage.
A chimney cap covers the flue opening and prevents water, animals, and debris from entering. If it’s missing, damaged, or poorly installed, rain can pour directly into the flue.
Bricks and mortar joints can crack over time, especially when exposed to moisture and freezing temperatures. As water freezes and expands in these small gaps, it breaks apart the masonry even more.
Flashing is the metal seal where the chimney meets the roof. If it becomes loose, rusted, or improperly installed, water can enter at this critical junction—often unnoticed until interior damage appears.
In some cases, the moisture you’re seeing is coming from inside. If your flue is blocked or improperly vented, condensation can form inside the chimney and mimic a leak.
Some chimney leaks are obvious. Others hide behind walls or ceilings for weeks or months before you notice a problem. Keep an eye out for these common symptoms:
If you see any of these signs, don’t wait—contact us to schedule an inspection before the damage worsens.
At Local Chimney Services, we follow a step-by-step process to accurately locate and repair chimney leaks. Here’s how we do it:
We start with a complete visual assessment of the chimney—inside and out. We also use moisture meters to check for hidden water intrusion in the surrounding walls or ceiling.
We inspect the crown and flue cap for cracks, gaps, and signs of rust or corrosion. If these components are compromised, they’re often the source of the leak.
Next, we examine the flashing at the base of the chimney. We check for lifting, rusting, or improper overlap with roofing materials that could allow water to enter.
We look for cracked, spalling, or porous bricks and mortar. These spots are often where rain and melting snow work their way in.
Inside the chimney, we check the firebox, damper, flue liner, and smoke chamber for rust, discoloration, or dampness—signs that moisture is entering from above.
Once we’ve identified the source, we provide honest, affordable repair options. Some of the most common fixes include:
All of our work is code-compliant and tailored to Rhode Island’s unique climate challenges.

A leaky chimney can be caused by a variety of factors, including damaged flashing, cracked chimney crowns, deteriorating mortar, clogged or damaged chimney caps, or worn-out seals. Water can enter through these areas, leading to potential damage to the chimney and surrounding structure.
Signs of a leaky chimney include water stains on the ceiling or walls near the fireplace, rusted chimney components, musty odors, or visible cracks in the chimney structure. You might also notice increased dampness in the fireplace or visible mold growth.
Chimney flashing is a metal barrier installed around the base of the chimney where it meets the roof, designed to prevent water from seeping into the chimney and the home. If flashing is damaged or improperly installed, it can lead to leaks around the chimney.
The chimney crown is the top part of the chimney that helps prevent rain and snow from entering the chimney structure. Cracks or damage to the crown can allow water to seep into the chimney, causing structural damage and rust.
Regular maintenance, such as inspecting and repairing chimney flashing, chimney crowns, and chimney caps, can help prevent water intrusion. Additionally, applying a waterproof sealant to the masonry can protect against moisture penetration and prolong the life of your chimney.
Leaky chimneys are typically repaired by identifying and fixing the source of the water intrusion. This can involve replacing or repairing damaged flashing, sealing cracks in the chimney crown, replacing a deteriorating chimney cap, or repointing mortar joints to restore the integrity of the chimney structure.
While some minor maintenance tasks, such as cleaning out debris or replacing a chimney cap, can be done by homeowners, leaky chimneys often require professional repair. Water intrusion can be a sign of serious damage that requires the expertise of a certified chimney professional to ensure the repair is done safely and effectively.
The cost of repairing a leaky chimney can vary depending on the extent of the damage and the repair needed. Minor repairs, such as replacing a chimney cap or sealing cracks, may cost between $150 and $500, while more extensive repairs, such as replacing flashing or chimney crown repair, could cost between $500 and $2,000.
