Brick that stays dark after rain
After a shower, brick darkens as it takes on water, then lightens again as it dries. A face that stays dark for days, while the rest of the house has dried, is holding more water than it should. That can mean porous brick drinking rain through its faces, or water arriving from above through the crown or a joint and soaking down.
On the Northside stack we tell those apart before recommending anything. When the brick faces are the path, a breathable repellent is the right treatment; when the water comes from an opening, the opening is closed first. Not every Northside chimney needs a repellent; the free inspection tells you, so call (904) 920-5495.
Northside is one of the named neighborhoods of Jacksonville. Northside falls within Duval County.
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
New mortar and the wait before treatment
Fresh mortar is still curing and giving off water after repointing. Coating it too soon can lock that moisture in.
When your Northside chimney has been repointed or rebuilt, we wait out the cure time on the product's data sheet and return for the treatment visit.

How deep a penetrating repellent goes
The protection from a penetrating product sits beneath the face of the brick. BIA puts the depth at up to about 3/8 inch for penetrants in general, with no film left on the surface. The maker of the siloxane we use states penetration of up to 1/4 inch or more, varying with how porous the surface is and how much moisture it holds on the day. That depth is what lets the treatment outlast wear of the outer face. It is also why the brick has to be dry: pores already full of water leave less room for the product to travel, and the treated zone ends up shallower.
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.
The crown takes a different product
The crown is the concrete or mortar slab across the top of the stack, and its job is harder than the brick's. Even a correctly sloped crown is close to level, so rain lingers on it and ponds wherever it has settled or cracked.
A penetrating repellent made for walls is not designed for that exposure. A sound crown with fine cracks is sealed instead with an elastomeric crown coating, which cures into a flexible membrane and comes with its own application limits. A crown with wide cracks or loose pieces needs repair or recasting. Either way it is priced apart from the brick treatment.

FAQ
Before any sealer goes on
Is there anything to prepare before treatment day?
The roof work can go ahead without you. We do need nearby windows and skylights to be reachable for covering, and plants or cars close to the chimney may need moving.
Can you treat a stucco chimney?
The product we use lists portland cement stucco among its surfaces. Cracks in the stucco are repaired first, and a test patch shows how it takes the product.
