New or rebuilt masonry
Newly built or rebuilt masonry holds water from the construction itself, and it needs to dry and cure before any repellent goes on. The data sheet we work from asks for new masonry to cure at least 28 days. BIA prefers a longer wait on new brickwork, so that salts carried out as the construction water dries, called new building bloom, are not trapped under a coating. When a chimney in Brentwood has been rebuilt above the roofline, the treatment is booked for a later date, and you know the earliest that date can be. Not every Brentwood chimney needs a repellent; the free inspection tells you, so call (904) 920-5495.
Brentwood is in Duval County. Brentwood lies inland.

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.
When brick in Brentwood needs a repellent
This far inland, salt spray is rarely the concern for Brentwood chimneys. Rain is. Some brick drinks water like a sponge and stays dark long after a storm.
A splash test on each face tells us whether yours does. If the brick sheds water, treatment is left off the estimate.

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.
The test patch before the whole chimney
Brick varies from wall to wall, and a treatment that looks invisible on one chimney may darken another slightly. A trial area shows how much product the brick drinks, how it looks once dry, and whether water beads on it after cure. BIA recommends trial areas of at least 10 square feet in a spot that represents the surface to be treated, cured as the product maker directs before judging. On a chimney, that means one section of one face done first, sprayed with water once it has cured, and compared side by side with untreated brick next to it before any decision on the rest.
Holding off while salts are still coming out
White efflorescence is a sign that water is still travelling through the masonry and depositing salt where it dries. BIA's position is that brickwork with a history of it should be coated only after the moisture source has been corrected, because salts that cannot reach the surface may crystallize just behind it and break the face. So the steps run in order: the deposit is brushed off dry, the water path is found and repaired, and the wall is watched for fresh deposits before any treatment is booked. If the white returns, the repair is not finished, and treatment waits.
Tested before any repellent goes on in Brentwood
- Product name and type: silane, siloxane or a blend of the two
- Covering glass, roofing, siding, paint and plants from overspray
- When to recheck the treatment, and how to tell it has worn
- Stucco or stone areas, and the product listing that covers them
Before any sealer goes on
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.
What if my chimney does not need treatment?
Then we tell you. If the brick sheds water and the joints, crown and flashing are sound, treatment is left off the estimate.
