Chimney Waterproofing & Moisture Protection

Water can damage a chimney through more than one path. Before recommending waterproofing, ABC Chimney Solutions checks the crown, cap, flashing, brick, mortar, stucco, chase cover and other likely entry points so a surface treatment is not used to hide a repair that should be completed first.

Chimney Waterproofing in Connecticut

Water can damage a chimney through more than one path. Before recommending waterproofing, ABC Chimney Solutions checks the crown, cap, flashing, brick, mortar, stucco, chase cover and other likely entry points so a surface treatment is not used to hide a repair that should be completed first.

A waterproofing plan, not one universal product

ABC Chimney Solutions selects the repair and moisture-protection approach for the actual masonry. Some projects need repointing, brick replacement or crown work before a water-repellent treatment makes sense. Others may benefit from stucco, custom top protection or a different combination of repairs.

Treat visible and developing damage

Moisture-damaged brick does not always fail all at once. ABC Chimney Solutions looks for early changes in the brick and mortar, not only pieces that have already fallen away, and can explain when repairing a broader area now may prevent repeated masonry work later.

Protection Inclusions

Also part of Caps & Waterproofing

A chimney cap does much more than keep animals out. The right cap helps protect the flue and top of the chimney from direct rain, snow and debris, and a larger custom cap can extend protection over the crown and upper masonry. ABC Chimney Solutions installs standard caps, multi-flue caps, custom stainless steel or copper caps and custom chase covers.

Questions & Answers

Chimney Waterproofing — frequently asked

What homeowners ask ABC Chimney Solutions most often about chimney waterproofing.

Is chimney waterproofing enough to stop every leak?

No. ABC Chimney Solutions first looks for damaged flashing, crown, cap, brick, mortar, chase-cover or other defects because waterproofing should not be used as a substitute for repairing an actual opening or failed component. Learn more about this service.

Can waterproofing help protect older brick?

It can when the masonry is suitable for the treatment. ABC Chimney Solutions evaluates the brick, mortar and existing damage first and then recommends the moisture-protection method that fits the chimney. Learn more about this service.

Do you repair the masonry before waterproofing?

ABC Chimney Solutions repairs cracks, failed mortar or damaged masonry when the project requires it so the water-protection system is applied to a properly prepared chimney rather than used to conceal a defect. Learn more about this service.

What does ABC Chimney Solutions mean by a waterproofing plan, not one universal product?

ABC Chimney Solutions selects the repair and moisture-protection approach for the actual masonry. Some projects need repointing, brick replacement or crown work before a water-repellent treatment makes sense. Others may benefit from stucco, custom top protection or a different combination of repairs. Learn more about this service.

What does ABC Chimney Solutions mean by treat visible and developing damage?

Moisture-damaged brick does not always fail all at once. ABC Chimney Solutions looks for early changes in the brick and mortar, not only pieces that have already fallen away, and can explain when repairing a broader area now may prevent repeated masonry work later. Learn more about this service.

What does chimney waterproofing do?

A breathable masonry treatment reduces how much water the brick absorbs while still letting the structure dry out. Absorbed water is what freeze cycles turn into spalling. It is one of the things ABC Chimney Solutions assesses when it looks at chimney waterproofing. Learn more about this service.

Is it the same as sealing the chimney?

No, and the difference matters. A non-breathable sealer traps moisture inside the masonry, which does more harm than leaving it alone. ABC Chimney Solutions can tell you which applies to your chimney when it looks at chimney waterproofing. Learn more about this service.

Will waterproofing fix a leak?

No. If water is entering through a cracked crown, a failed cap or bad flashing, waterproofing the brick does not address it. ABC Chimney Solutions will not sell it as a leak fix. Learn more about this service.

Should the masonry be repaired first?

Yes. Treating open joints and spalled brick is work done on a surface that is already failing, so repointing comes before treatment. This is part of what ABC Chimney Solutions checks before quoting chimney waterproofing. Learn more about this service.

How long does the treatment last?

It depends on the masonry, the exposure and the product. ABC Chimney Solutions will tell you what the specific treatment is expected to give rather than quoting a round number. Learn more about this service.

Is it worth doing on a new or rebuilt chimney?

It is often the sensible finish to a rebuild, because it starts protecting the masonry from its first winter rather than after damage has begun. ABC Chimney Solutions can tell you which applies to your chimney when it looks at chimney waterproofing. Learn more about this service.

What does a chimney cap do?

It keeps rain, snow, animals and debris out of the flue and stops embers leaving it. An open flue takes water straight down onto the damper, the smoke chamber and the liner, which is why a missing cap shows up as damage lower down. It is one of the things ABC Chimney Solutions assesses when it looks at chimney waterproofing. Learn more about this service.

How do I know if I need a new cap?

Rust, a cap that has lifted or moved, damaged mesh, or no cap at all. On the Connecticut shoreline, salt air corrodes metal above the roofline noticeably faster, so a cap there is worth looking at sooner. Ask ABC Chimney Solutions about it when you book chimney waterproofing. Learn more about this service.

What is a chase cover and how is it different?

A chase cover is the metal top on a framed chase rather than a masonry chimney. When it rusts it holds water instead of shedding it, and the staining down the chase is usually the first thing a homeowner notices. ABC Chimney Solutions covers this as part of its chimney waterproofing work in Connecticut. Learn more about this service.

Does waterproofing actually work?

A breathable masonry treatment reduces how much water the brick absorbs while still letting the structure dry. It is not a substitute for fixing a cracked crown or failed flashing, and ABC Chimney Solutions will not sell it as one. Learn more about this service.

What Homeowners Say

Reviews from the towns we work in

Eight of the several thousand chimneys we have swept, lined and rebuilt across Connecticut.

The inspection found a cracked clay liner two other companies had missed. Relined in stainless the following week and the smoke coming back into the room stopped dead.
Sarah MitchellHomeowner · West Hartford, CT
Open fire had not been swept in six years. They pulled out a shocking amount of creosote, sheeted the whole hearth, and left the room spotless.
Michael TurnerHomeowner · New Haven, CT
Damp was coming through the chimney breast for two winters. They traced it to a failed crown, recast it and waterproofed the brickwork — bone dry since.
Elena RossiHomeowner · Stamford, CT
Flashing had lifted and the damper had seized shut. Both repaired in one visit, and they showed me the before and after photos on the roof.

Full stack rebuild above the roofline on a 1920s house. They matched the original brick and mortar so closely the neighbors asked who did our repointing.
Priya RamanHomeowner · Greenwich, CT
Booked the sweep on Monday, done Tuesday. The photographs and written flue report are more thorough than the survey we paid for when we bought the place.
Tom AlvarezHomeowner · Fairfield, CT
Our wood stove never drew properly. They worked out the flue was oversized for the appliance, fitted an insulated liner, and it lights first time now.
Grace OkaforHomeowner · Simsbury, CT
Needed the chimney looked at fast for a house sale. On the roof the next morning, and I had a clear answer and a price the same afternoon.
