Why the crown and flashing come first

The top of the stack and the roof line are two of the ways water gets into a chimney, besides its faces. The crown sheds rain from the top of the chimney, and the flashing closes the seam where the roof meets the chimney.

If either has failed, water runs into the masonry faster than any treatment could keep out. So when we find a cracked crown or loose flashing on your chimney in Palm Valley, those repairs come ahead of any repellent, and the treatment is scheduled after they are done. A repellent over a failed crown is money spent on the wrong part. Damp patches on the chimney in Palm Valley? Call (904) 920-5495 and we will test the brick.

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.

Old sealers near the coast in Palm Valley

Chimneys close to the ocean often carry old coatings put on to keep salt out. Many have gone cloudy or started to peel, and a new repellent will not soak through them.

We test the old coating in Palm Valley, and we report whether it must come off first.

The crack width a repellent will not bridge

A penetrating treatment lines the pores of the masonry; it does not fill a gap. BIA's clear-coatings note draws the line precisely, saying these products seldom keep water out of cracks more than 0.02 inch wide. That is about half a millimeter, roughly the thickness of five sheets of printer paper stacked together.

Wider openings, such as an open head joint, a cracked brick or a separation under the crown, pass water straight by the treated surface around them. Those are fixed with mortar or new units first. The treatment, if it still makes sense, comes once the wall is closed.

How a film sealer holds water in brick

Clear products that sit on top of the brick, such as acrylics, stearates, waxes and urethanes, dry into a continuous skin. The skin can span a hairline crack, which sounds like an advantage, but it also chokes the vapor that has to leave the wall when it dries. On a chimney, water arrives from above, from the flue side and through joints as well as through the faces.

If that water cannot escape outward at its normal pace, it stays in the brick longer, and BIA warns that salts can collect under such a skin and harm the face. For that reason we do not use film sealers on chimney masonry.

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.

Before any sealer goes on

Can the treatment be done the same day as repointing?

No. Fresh joints need at least 72 hours to cure first, according to BIA and the product's data sheet, so treatment is a second visit.

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.
