We Trace the Source

Water often shows up feet away from where it gets in. We work from the top of the chimney down until we find the actual entry point.

Breathable Products Only

Masonry has to let moisture escape. We use vapor-permeable repellents, not paints or film sealers that trap water inside.

Honest About Roof Leaks

If the water is not coming from the chimney, we will tell you, so you can call the right trade instead of paying for the wrong fix.

Why Chimneys Leak in Florida

A chimney is a tall, exposed structure with an opening at the top and a joint cut through your roof. During Florida’s rainy season, afternoon storms can drop heavy rain in a short time, and tropical systems can drive it sideways for hours. Water that gets in follows the easiest path down, which is why a stain on your living room ceiling can start at a crack several feet away on the crown.

Brick, concrete block, mortar and stucco are all porous. They soak up water like a hard sponge. Normally that water dries back out, but when a chimney stays damp through a humid summer, moisture works deeper, rusts metal parts such as the damper and firebox, and feeds the musty smell many homeowners notice from their fireplace.

Where the Water Gets In

• A cracked crown, or a flat crown that lets water sit

• A missing or damaged cap, so rain falls straight down the flue

• Failed flashing or dried-out sealant where the chimney meets the roof

• A rusted, dented or badly sloped chase cover on a factory-built chimney

• Cracked stucco or open mortar joints on the chimney walls

• Porous brick that has never been treated

• Less often, condensation inside the flue, which can happen when some gas appliances vent into an oversized masonry flue

Signs of a Chimney Leak

• Drips or puddles in the firebox after rain

• Stains on the ceiling or wall beside the chimney

• Peeling paint or loose wallpaper near the fireplace

• A musty or damp smell from the fireplace in summer

• Rust on the damper, the firebox or the frame of the glass doors

• White, chalky deposits on the brick (efflorescence)

• Brick faces that flake or pop off (spalling)

• Damp or stained framing in the attic next to the chimney

How We Find the Leak

Guessing is the most expensive way to fix a leak. We start at the top with the cap, crown and flue, then check the flashing and the roof joint, then the chimney walls, and the attic where it is accessible. On factory-built chimneys we also check the seams of the chase cover, the storm collar around the flue pipe, and the siding joints on the chase.

When the source is not obvious, we may run a controlled water test, wetting one area at a time while someone watches inside. It takes longer than spraying sealant everywhere, but it tells us which part is actually letting water in, so you pay to fix that part.

What Waterproofing Does, and What It Does Not

Waterproofing is not a first fix. It is the last layer, applied after the actual openings are closed. Spraying repellent over a cracked crown or loose flashing will not stop a leak. Once the crown, flashing, cap and mortar joints are sound, a water repellent reduces how much rain the brick and mortar soak up between storms.

The product matters. Masonry has to breathe, meaning it must be able to let water vapor escape. Paints, many clear sealers and products that form a surface film can trap moisture inside, and in Florida’s humidity that trapped water can make the surface flake and spall. We use vapor-permeable water repellents made for masonry, which soak into the surface instead of coating it.

What Affects the Cost

• How many entry points there are. Many leaks have more than one.

• Whether the damage has spread, for example rotted chase framing or wet roof decking next to the chimney.

• The size and height of the chimney and the type of roof.

• Masonry or factory-built. The repairs are different.

• Whether waterproofing is included, and how much wall area it covers.

Drywall, ceiling and paint repairs inside the house are usually separate work, done once the leak is stopped and the area has dried out.

When You Do Not Need Waterproofing

If your chimney is a factory-built chase covered in siding, masonry water repellent does not apply. The fix is usually the chase cover, the storm collar or the siding joints. A painted stucco chimney in good shape may only need its cracks repaired and recoated. And if the water is actually coming from the roof, a skylight, a plumbing vent or an air conditioning line near the chimney, treating the chimney will not help. We will say so.

Before Storm Season

The Atlantic hurricane season runs from June 1 to November 30. Late spring is a good time to have the top of the chimney checked, because a small crack or a loose cap is far easier to fix before the first tropical storm than after water has been getting in all summer. If a storm has already done damage, see our page on storm and fire damage repair. For other chimney problems, start with our chimney repair overview, or call (813) 797-5797.

★ FAQ

Frequently Asked Questions

It depends on the product, how much sun and rain the chimney gets, and whether the underlying repairs hold. Manufacturers publish their own expected service life. We will tell you what the product we use is rated for and when it makes sense to have it checked again.

Caulk on flashing is a short-term patch at best. Florida sun dries out and cracks most sealants, and caulk cannot fix a cracked crown or porous brick. Roof work is also risky. If you do patch it for now, have the chimney inspected before the next storm.

Usually, yes. Wind-driven rain finds the weakest spot first. A joint that leaks in a tropical storm is often letting smaller amounts of water in during ordinary storms too, just not enough to show inside yet.

Penetrating repellents generally do not leave a shiny coating the way paint or film sealers can. If you are concerned about appearance, ask us to treat a small test area first so you can see the result.

We use breathable masonry products that do not trap Florida humidity inside the walls.

We tell you when the leak is not the chimney, so you do not pay for the wrong repair.

How We Fix a Chimney Leak

Find it, fix it, then protect it

Waterproofing comes last. Sealing over an open crack or a failed flashing joint only hides the problem for a while.

Tell Us When It Leaks: Every storm or only wind-driven rain? Which room? The pattern narrows down the source.

Top-Down Inspection: Cap, crown, chase cover, flashing, walls, and the attic where we can reach it.

Water Test if Needed: We wet one area at a time while someone watches inside, until the leak shows.

Photos and Quote: You see the entry points and get a written quote for closing them.

Repair the Entry Points: Crown, cap, flashing, mortar, stucco or chase cover, whichever is failing.

Waterproof Where It Helps: A vapor-permeable repellent on sound brick or block.

Check After Rain: Tell us after the next heavy storm if you see any sign of water.
