Expert Chimney Leak Repair in Norwalk CT: Stopping the Damage Before It Spreads
At Safeside Chimney, we were recently called out to a home in Norwalk, CT after the homeowner reported persistent water intrusion around their chimney during heavy rain. What we found was a classic case of improperly installed chimney flashing, a situation we’ve seen too often and one we knew exactly how to resolve.
Diagnosing the Source of the Chimney Leak
Upon arrival, our technicians evaluated all four sides of the chimney. We discovered that the existing counter flashing—installed by a roofing contractor—was only nailed and sealed with silicone. While this might keep water from running directly down the exterior masonry, it offers very little protection during wind-driven rain or prolonged storms. The shallow tuck depth of the flashing, only about half an inch, was allowing water to bypass the flashing and seep into the brickwork.
This type of water intrusion leads to ongoing deterioration if left unresolved, especially in older chimney structures. Fortunately, the chimney’s structure itself was solid, so we moved forward with a complete flashing replacement.
Proper Copper Flashing Installation
Our solution was to completely remove the existing counter flashing and install new copper counter flashing—tucked a full two inches into the brick joints and sealed with high-quality waterproof cement. This method ensures that water sheds away from the masonry and cannot seep behind the flashing, even under extreme weather conditions. The new flashing not only prevents leaks but also preserves the structural integrity of the chimney for years to come.
Addressing Hidden Water Damage in Norwalk, CT
During the inspection, we also identified an additional concern: an oil boiler venting into an oversized chimney. The exhaust was cooling too quickly and condensing inside the flue. When mixed with oil soot, it created sulfuric acid, which had begun to deteriorate the top portion of the chimney and surrounding roofing materials.
To stop further acidic condensation damage at this residence, we performed a full sweep of the oil boiler flue, cleared out all acidic residue, and replaced damaged furnace cement around the connector pipes. We also removed improperly sized mesh and installed three new stainless steel critter guards to protect all venting systems from debris and animal entry.
Quality Craftsmanship, No Subcontracting
As always, all work was completed by our in-house technicians—no subcontractors. We take pride in maintaining clean job sites and leaving properties better than we found them. This project not only resolved the active leak but also prevented future moisture-related issues from occurring.
