Is water getting into your chimney? Chimney leaks happen when mortar cracks, weathered bricks, or flashing is old. At GMT Home Services, we know how quickly a small leak can become a big problem—water damage, rust or safety risks for your family. That’s why we’re here to help with full chimney leak repairs that protect your home and your peace of mind. Calling a reputable chimney company ensures all issues are found, and all necessary services are done to prevent further damage.
A chimney leak occurs when water gets into the chimney system through weak points like an unlined brick chimney, damaged bricks, cracked mortar or bad flashing. Chimney bricks are prone to water damage because bricks and mortar are porous and can absorb moisture. These weaknesses can come from chimney brick aging, severe weather, poor construction or lack of maintenance. Once water gets in, it can damage the masonry, weaken the chimney liner, and create safety hazards such as carbon monoxide exposure. Rusting of the damper and other metal parts can also happen and compromise the chimney’s structure and function. A leaky chimney can cause big damage if left unaddressed. Finding the source of the chimney leak and repairing it in time can save homeowners from big and costly problems.
Water Stains Near Chimney: Yellow-brown stains on ceilings or walls near the chimney mean a leaky chimney. If ignored, these stains can spread and cause more interior damage.
Musty Odor: A persistent damp or musty smell around the fireplace means water is getting in and possibly mold growth, which can be a health risk.
Rust on Firebox or Damper: Rust on the firebox or damper means moisture exposure, weakening of metal parts, and increased fire risk.
White Stains on Chimney Exterior: Efflorescence (white staining) on the chimney exterior indicates water seeping in, which can degrade bricks and mortar over time.
Damaged Wallpaper or Paint Near Chimney: Bubbling paint or peeling wallpaper near the chimney means water is getting in. Fix it quickly to prevent more serious wall damage.
Deteriorating Mortar Joints: Loose or crumbling mortar joints mean water is getting in and weakening the chimney structure. Fix it now for stability.
Leaks can happen anywhere in the chimney, from the ceiling to the brickwork, chimney cap, flashing or chimney crown. Maintenance is your best defense against surprise leaks. Our chimney sweep services in Connecticut offer full inspections and cleaning to keep your fireplace safe and efficient all winter long and year round. We’ll find the signs of wear, diagnose the leaks and recommend the best fix—because catching it early is the key to avoiding big repair bills later.
Chimney Cover Issues: Without a proper cover or chase cover, rain, snow, debris or animals can get in the chimney directly. The cover and cap work together to block moisture while allowing smoke to exit. If either is damaged, replacement may be needed to function.
Brick and Mortar Wear: Cracks in mortar and crumbling bricks allow water to get in. Tuck-pointing and brick replacements can fix these issues, and adding waterproofing afterwards will protect the repairs.
Condensation from Gas Fireplaces: Moisture from gas fireplace exhaust can condense inside the chimney, especially if it’s unlined. Installing a chimney liner can prevent interior water damage and protect surrounding areas.
Flashing Problems: Flashing at the base of the chimney prevents leaks. Loose or worn flashing means water can get in and damage the attic and wall areas. A roofer can inspect and replace the flashing to prevent further leaks. Water stains on ceilings and walls can be a sign of a roof leak, and often, it starts from the chimney flashing. It’s important to have professional roofing contractors inspect and address these problems.
Black Liquid Leaking from Chimney: This dark liquid or “creosote” often means poor ventilation. When moisture mixes with creosote deposits, it can cause chimney leaks. Cleaning and inspecting the chimney regularly can fix this.
A damaged chimney crown is a common source of chimney leaks. The chimney crown is the cement or mortar at the top of the chimney that blocks water from leaking and entering the chimney. Over time, it can be damaged from weathering, settling, or other factors and allow water to get in.
If you think your chimney crown is damaged, have it inspected and repaired by a professional chimney sweep or repair technician. They can assess the damage and recommend repairs to prevent further water intrusion.
In some cases, a damaged or leaking chimney crown may need to be replaced. This involves removing the old crown and installing a new one. A professional chimney sweep or repair technician can do this and ensure the new crown is installed properly to prevent future leaks.

A missing or damaged chimney cap can also cause chimney leaks. The chimney cap is the metal or concrete at the top of the chimney that blocks water and debris from entering.
If your chimney cap is missing or damaged, you need to have it replaced or repaired as soon as possible. A professional chimney sweep or repair technician can install a new chimney cap or repair the existing one to prevent further water intrusion.
When choosing a new chimney cap, make sure to choose one that’s durable and weather-resistant. A stainless steel or aluminum chimney cap is a good choice, as it can withstand harsh weather and prevent water and snow from getting in the chimney.
Condensation and moisture can also cause chimney leaks. When the air in the chimney is cooler than the air outside, condensation occurs, and water forms inside the chimney. This can cause leaks and damage to the chimney and surrounding areas.
To prevent condensation and moisture, make sure your chimney is properly insulated and ventilated. A professional chimney sweep or repair technician can inspect your roof and chimney and recommend repairs.
In some cases, a chimney liner may be needed to prevent condensation and moisture issues. A chimney liner is a metal or ceramic tube installed inside the chimney to block water and debris from entering.
Chimney leaks if not addressed quickly can cause:
Structural Damage: Water gets in the mortar between the bricks, causing cracks, crumbling and structural weakness.
Interior Water Damage: Chimney leaks can cause unsightly water stains on walls or ceilings, which can be expensive to repair.
Damage to Fireplace Components: Fireboxes and dampers can rust or get damp and reduce the efficiency and safety of your fireplace.
Unaddressed water leaks can accelerate chimney deterioration and cost you big time. By recognizing signs like water stains, musty odors or visible cracks, you can act fast and prevent further damage. Regular chimney inspections are key to detecting leaks early, maintaining chimney integrity and keeping your home safe.
Regular chimney inspections are important to prevent chimney leaks and to ensure the health and safety of the chimney system. A professional chimney sweep or repair technician can inspect your chimney and catch any issues before they become major problems.
During the inspection, the technician will inspect the interior and exterior surfaces of the chimney, including the chimney cap, crown, liner, and roof flashing. They will look for any signs of damage, wear, deterioration, or leaking chimneys and recommend repairs to prevent future leaks.
Regular chimney inspections can prevent costly repairs and keep your chimney system healthy and safe for the long term. We recommend having your chimney inspected at least once a year or more often if you use your fireplace or wood stove.
Preventing chimney leaks is key to a safe, efficient, and long-lasting chimney structure. Keeping your chimney components in good condition, especially by waterproofing, can stop water from causing costly damage.
Waterproofing the masonry and crown of the chimney with a sealing compound will block water from seeping into existing cracks and creating further structural issues. Regular maintenance and early detection are key: Watch your chimneys for signs of leaks like discoloration, efflorescence, or dampness. When you see these signs, call a professional chimney sweep or repair technician ASAP to prevent further damage and costly repairs down the line.
