Chimney repair for homes in Lake Holden

Fix the water source before the stain

A stain on the ceiling is where a leak ends, not where it starts. Repainting it, replacing drywall or scrubbing the brick before the water is stopped means paying for the same fix twice, because the mark can come back with the next hard rain.

BIA guidance on maintaining brick says to investigate and find the moisture source before attempting repairs meant to correct water entry. It also suggests a visual check for an obvious source, such as missing or deteriorated materials, before any deeper investigation, since that may save time and money.

So the order on your estimate runs from the source outward. The repair that stops the water comes first, and interior touch-ups or cleaning come after, once the leak is fixed and the masonry has had time to dry. For homeowners in Lake Holden, that order keeps the money on the part that is actually failing.

What a rain cap does and what it cannot do

A rain cap sits over the flue outlet and keeps rain and debris from dropping straight down the lining. That spares the damper, the smoke chamber and the firebox from water that would otherwise run down inside.

Three details matter when one is chosen. On a masonry chimney, the Florida Building Code sets the open area under a rain cap at no less than four times the area of the flue outlet it serves. BIA guidance says to get the maker's information on how a manufactured rain cap affects gas flow, and it says a metal cap should be corrosion resistant. A cap that restricts the outlet, or one that rusts, trades one problem for another.

What a rain cap cannot do is protect the crown around it. Rain hitting a cracked crown still soaks into the masonry, cap or no cap. Our chimney cap replacement service fits the cap itself, and when the crown underneath is failing, your Lake Holden estimate says so on a separate line.

Broken and spalled brick faces

Spalling is when the face of a brick breaks away and leaves a rough, recessed surface behind. BIA maintenance guidance notes that water gets through broken or badly spalled brick, and that the damaged units may have to be replaced.

Replacing a brick without finding out why it spalled only sets up the next one, so the joints, the top and the flashing around the damage are checked first. Our chimney brick replacement service handles the work, and on your Lake Holden home the estimate lists the bricks to be replaced along with the cause they point to.

• The damaged brick is broken out to make removal easier
• Mortar around the opening is cut away without harming the neighbors
• New brick and the opening are fully buttered and the brick pressed in
• Joints are pointed and tooled to match the original profile

Every masonry chimney needs a sound lining

The Florida Building Code says masonry chimneys shall be lined, and that the lining must suit the type of appliance connected, following that appliance's listing and instructions. The lining is the inner passage the smoke travels through, and it keeps smoke and flue gases inside the flue rather than in the brick around it.

Some chimneys were built without one, and others have a lining that has cracked, shifted or lost pieces. From the room you rarely see it. The clues tend to be indirect, like tile fragments in the firebox or smoke where it should not be.

Because the code requires a lining, a flue without one, or with a broken one, stays out of use until it is repaired. On homes in Lake Holden, our crew checks the lining from the firebox and from the top, and the estimate says whether the flue needs repair, relining or nothing at all.
