Rechecking an earlier treatment
Every clear repellent wears in time, and BIA does not treat any of them as permanent. If your Callahan chimney was treated years ago, a quick test shows where it stands: wet each face and watch. Protected brick throws the water off and keeps its color, while brick whose protection has worn turns dark as it soaks the water in.
We run that test from the roof, mark which faces still repel water and which do not, and treat only the faces that need it. Coating a face that is still protected adds cost and can reduce how well the wall breathes. Damp patches on the chimney in Callahan? Call (904) 920-5495 and we will test the brick.

What's Included

How It Works
How chimney waterproofing runs
-
Water test on brick and joints
We wet the faces and watch where the brick drinks, and check the crown, cap and flashing for openings.
-
Openings repaired, then cured
Joints, brick, crown and flashing are fixed first, and the data sheet's cure time runs before any treatment.
-
Test patch, then a flood coat
A patch shows how your brick takes the product. Then it goes on from the bottom up with a low-pressure sprayer, wet on wet.
-
Splash test and paperwork
Treated brick should bead water and stay light. You get the product, the faces treated and the cure time in writing.
Local Conditions
Why more repellent is not better
A heavier coat can seem like better value, but too much repellent cuts how well the brick breathes, and breathing is the whole point of a penetrating product.
We apply at the coverage rate on the data sheet, and the test patch on your Callahan chimney shows how much the brick takes.

New masonry and the four-week wait
A freshly built or rebuilt section of chimney is full of water from its own mortar. The maker of the siloxane we apply asks for a minimum 28-day cure on new masonry before treatment. BIA suggests waiting longer still on new brickwork, at least a month after the building is closed in and preferably a year, so the salts carried out as that construction water dries, known as new building bloom, are not sealed under a coating. When the top of a chimney has been rebuilt, the repellent is scheduled after that cure, with the earliest date it can go on agreed in advance.
The splash test for when to reapply
You can check whether a chimney's treatment is still working without any tools beyond a spray bottle or a garden hose on a gentle setting. Wet a patch of each face. Brick that is still protected throws the water off in beads and keeps its dry color; brick that has lost its protection turns darker within seconds as it soaks the water up.
We run that test on every face, since the face that takes the most weather wears first. Only faces that absorb get another coat, which saves product and avoids stacking coats where they are not needed. The results, face by face, go into the job notes.
Cleaning the brick before treatment
A repellent has to reach the pores, and anything sitting on the surface blocks it. BIA's note is plain that the wall must be clean when the product goes on, since heavy dirt reduces penetration and shortens the life of the treatment. Chimney brick is cleaned gently: loose salt brushed off dry, dirt and growth scrubbed with a stiff fiber brush and water, and cleaning products used only where the brick maker's guidance allows them. Pressure washing at high settings can drive water deep into the brick and damage joints, and it adds days of drying before treatment can start.

FAQ
Before any sealer goes on
Do you waterproof chimneys in Callahan?
We do, as part of our chimney work there. A visit starts with a look at how water is getting in, and treatment is only recommended when the brick itself needs it.
Does the repellent change the color of the brick?
The product we use leaves little or no shine, though very dense brick can go a shade darker. You see the trial patch dry, next to untreated brick, before the rest is done.
