Chimney Leak Repair

When you see water leaking into your home in or around your chimney, we know your first thought isn’t a happy one. And your next thought, generally, is: “Where’s it coming from?”

That’s unfortunately not always the easiest question to answer. Water is tricky, and will take every opportunity to find its way into your chimney system and into your home. There are, however, some common places that leaks spring up, and with our decades of experience, Mason’s Chimney Service has adopted a 31-Point Leak Inspection process that ensures that we find the source or sources of your leaks and repair them. Find it here.

We know it’s frustrating to deal with a leak, and we go the extra mile to make sure the process of repairing a chimney leak is as pain-free as it can be. Our goal as a company has always been to provide the kind of service that makes every customer a life-long customer, and you can expect that kind of service the first time we come to your home and every time afterward.

Chimney Leaks Can Pop Up In A Variety Of Places

Water is by far your chimney system’s worst enemy, and that’s why the chimney was designed with a variety of parts geared toward keeping water out. Those parts were built to bolster potential trouble zones, so it’s no surprise that they’re often the places that wear out and lead to leaks.

Chimney Cap
The metal cap at the very top of your chimney is there for a variety of reasons, and keeping water, snow and other precipitation out is a big one. Without it, your flue is directly open to the elements. If your chimney cap is damaged (or if you don’t have one), let our technicians repair or install a cap that will protect your flue for years to come.

Chimney Crown
Below the chimney cap, you’ll generally have a chimney crown made of mortar or cement, designed to push water and snow away from your flue. Since it’s getting directly bombarded year-round, your chimney crown can develop cracks, gaps or spalling. We’ll inspect your chimney crown to see if leaks are springing up there, and if so, repair it (or if need be, rebuild it) to last.

Chimney Flashing
Seams are always tough spots, and the seam that connects your chimney to your roofline is protected by metal flashing. Flashing can tear or lift, or its caulking can come off or loosen, causing leaks. We’ll check your flashing, and if it’s causing a leak, perform the custom work needed to repair it.

Preventive Measures Can Make A Big Difference

Mason’s Chimney Service can recommend a waterproofing sealant that will help keep water from making its way into your masonry chimney.

We use ChimneySaver Water Repellant, a product that chimney professionals have been using for 25 years. It’s vapor-permeable, which means it can seal your masonry and stop the encroachment of water, but still allow the bricks and mortar to “breathe,” expelling harmful gases and small particles from the chimney.
