Situated along the shores of the Long Island Sound on Connecticut’s Gold Coast, winter in Fairfield is much milder than in other New England towns. However, it still experiences freezing temperatures, snow, and icy conditions. These conditions lead to a phenomenon known as the freeze-thaw cycle, which is the leading cause of masonry damage and chimney leaks for homeowners along the Gold Coast.
For over two decades, National Chimney Cleaners has been a trusted partner for homeowners in Fairfield County, specializing in expert repairs for leaky chimneys and protecting homes from water damage.
Why Is My Chimney Leaking?A chimney leak isn’t always as apparent as a puddle in the fireplace. You might notice damp walls, a musty odor, or “efflorescence,” a white, powdery stain covering those beautiful red bricks. Water can enter a chimney system through several entry points, usually due to improper maintenance or weather-related damage.
Our trained technicians are experts in locating the source of the leak and applying permanent repairs, including:
In the early stages of masonry damage, when the mortar is decaying but the bricks are still intact, we typically recommend tuckpointing. It is a restorative process in which we use specialized tools to carefully remove old, deteriorating mortar from the joints, replacing it with a fresh, durable mortar compound for a seamless repair.
The chimney crown’s location at the top of the stack makes it more vulnerable to weather-related damage, which is a common cause of a leaky chimney. When a crown has surface cracks or fissures, we can apply a special sealant called CrownSeal®. This waterproof coating stops the leak, helps prevent further water damage, and comes with a 10-year warranty.
Flashing is the metal sheet that seals the seam where the chimney meets the roofline, preventing water from leaking through the gap. When the flashing is warped or rusted, it becomes a significant source of chimney leaks. Sometimes all it needs is a simple re-caulking with a waterproof bonding agent; in other cases, we need to replace the entire flashing.
In severe cases of water-damaged masonry, individual bricks may begin to flake, crumble, or spall, compromising the chimney’s stability. By replacing the damaged bricks, we can stop the damage from spreading to the rest of the stack, preventing the need for a more expensive partial or complete rebuild. We carefully match the bricks and mortar to the undamaged sections for a seamless repair. The result is a beautiful, structurally sound chimney.
An annual chimney inspection is the best way to help prevent chimney leaks. During this comprehensive interior and exterior examination, our technicians repair damaged components, such as decaying mortar or cracks in the crown and liner, before they spring a leak. However, if a chimney leak occurs, your first course of action is to contact us for immediate repair, followed by professional chimney waterproofing.
After completing the masonry repairs, we recommend using a professional-grade vapor-permeable waterproofing sealant. This environmentally friendly, water-based formula penetrates the brickwork and bonds to the pores rather than merely coating the surface. It allows the chimney to “breathe,” enabling trapped water vapor to escape while effectively repelling rain, ice, and snow, and protecting against UV exposure.
