Finding the water path before any spray

Waterproofing your chimney in St. Nicholas is the last step of a job. Before anything is sprayed, we find out how water is getting into the masonry: through open joints, cracked brick, the crown, the flashing, or through the brick faces themselves. The first four are repairs. Only the last is what a water repellent is made for. So a visit starts with a close look and a splash test, and the estimate lists the repairs, the cure time they need, and then the treatment, with the product named so you can read its data sheet before you agree. Damp patches on the chimney in St. Nicholas? Call (904) 920-5495 and we will test the brick.

Counted as a direct line, Jacksonville and St. Nicholas are roughly 3 miles apart. St. Nicholas is a neighborhood within the City of Jacksonville.

How It Works

Splash, repair, patch test, flood

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

Painted chimneys in St. Nicholas

The repellent we use is not made for painted or glazed brick, since paint already forms a film on the face. Spraying over it does nothing useful.

For a painted chimney in St. Nicholas, we talk through the options for the paint before any treatment is priced.

Waiting after the joints are repointed

New mortar in a joint is still hardening and still giving off water for days after it is placed. Coating it too soon can interfere with that cure and lock the moisture in. BIA's pre-coating checklist sets a floor of 72 hours for freshly repointed mortar and repaired sealant joints, and the maker of the repellent we use sets the same interval after tuckpointing or other repairs.

On a chimney that has just been repointed, treatment is therefore booked as a separate visit. Writing the cure period on the estimate keeps anyone from spraying on the same afternoon the trowels are put away.

Temperature limits on the data sheet

Clear repellents cure through a chemical reaction, and heat and cold both change how that reaction goes. The product's directions set the window at 40 to 100 degrees Fahrenheit for both the surface and the air, holding for three hours after application, and BIA gives a similar typical range for brick coatings. A chimney face in full sun can run well above the air temperature, so on a hot day the work may be timed for the morning or started on the shaded faces first. The same timing keeps the product from flashing off before it has soaked in properly.

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.

FAQ

Waterproofing questions from St. Nicholas

Do you waterproof chimneys in St. Nicholas?

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.

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.
