Test patches on Fernandina Beach chimneys

Every chimney's brick takes a repellent a little differently. Dense brick may darken slightly, porous brick may soak up more product per square foot, and an old coating may react. So before the whole stack is done, a trial area goes on one representative face and is left to cure.

We come back to it once it has dried, look at it in daylight for any change of color or sheen, and spray it with water to watch it shed. Only when the trial looks right and sheds water does the rest of the chimney get treated. Not every Fernandina Beach chimney needs a repellent; the free inspection tells you, so call (904) 920-5495.

Fernandina Beach is part of Nassau County. The 2020 Census count for Fernandina Beach was 13,052 people.

How chimney waterproofing runs

Splash test every face
Water on each face shows where the brick soaks it up, and the crown, cap and flashing are checked for openings.
Openings closed and cured
Joints, brick, crown and flashing are repaired first, and the cure time on the data sheet runs its course.
Clean, patch test, then flood
The brick is cleaned, a test patch dries beside untreated brick, then the repellent goes on from the bottom up.
Dry and retest
Once it has cured, we splash the faces again so you can see the water bead off.

Timing treatment around coastal weather in Fernandina Beach

A penetrating repellent needs visibly dry brick and a stretch without rain while it soaks in. Near the ocean in Fernandina Beach, we watch the forecast and the brick itself before we set the day.

If rain arrives early, the work stops and picks up once the brick is dry again.

The repairs that come first and the water repellent after them are both discounted.

Silanes on dense surfaces

Of the clear repellents, silanes have the smallest molecules. BIA's note explains that the small size helps them get into dense materials, and that they are supplied at high concentrations of active ingredient. The reaction that makes them water-repellent goes fastest on alkaline surfaces like concrete and concrete block, which act as their own catalyst.

On less alkaline clay brick, some products carry an added catalyst to help. Where a chimney has a very dense brick, a block section, or a concrete element that needs treatment, a silane or a blend led by silane may suit it better, and we explain the choice made.

Visibly dry brick and a rain-free window

For a penetrating product to soak in, the pores need to have room for it. The maker's directions call for clean, structurally sound masonry that is visibly dry, and they rule out wet or saturated surfaces. They also ask for a six-hour window with no rain expected, unless the treated wall can be sheeted with plastic. After a run of wet days, brick can look dry at the face while still holding water further in, so on the day we check the brick itself, pressing and looking at freshly scraped mortar, rather than relying on the forecast and the look of the surface alone.

Repellent does not seal the roof joint

The roof joint around a chimney is sealed with metal: step flashing woven into the roof covering and counterflashing let into the masonry above it. When that metal lifts, rusts or loses its seal, water runs down between the chimney and the roof framing, without touching the brick faces a repellent protects. Stains on a ceiling near the chimney, or wet framing in the attic beside it, send us to the flashing before any treatment is priced. Flashing repair is its own job, and damage to the roof covering itself is referred to a roofer.

Before any sealer goes on

Is chimney sealing the same as waterproofing?

People use both words for the same job. What matters is the product: we use penetrating repellents that let the brick breathe. Film sealers and paint stay off.

Will waterproofing stop water coming into my fireplace?

Not if the water comes down the flue or through the crown. Those paths are closed with a cap or crown repair, and treatment of the brick faces comes afterward if it is still needed.
