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 Crawford, 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 Crawford? Call (904) 920-5495 and we will test the brick.

How our waterproofing specialists treat a chimney in Crawford

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.

Painted chimneys in Crawford

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 Crawford, we talk through the options for the paint before any treatment is priced.

Siloxanes and clay brick

Siloxane molecules are larger than silanes, and they link chemically to the silica and alumina in fired brick and in mortar. In BIA's assessment they give good penetration and repellency and have worked well on certain brick walls, which is why the note suggests a siloxane, or a siloxane and silane blend, for exterior brick. Some siloxanes tolerate a slightly damp surface. The one we apply on chimneys is a modified siloxane, and its maker describes it reacting with the minerals in the masonry, in the presence of ultraviolet light and moisture, to form a water-repellent zone just below the face. Nearby glass needs protecting for the same chemical reason, since glass is mostly silica.

More is not better

A heavier coat of repellent can seem like better value. BIA's note says the coverage rate is critical, because putting on too much can cut the breathability of the masonry, and breathability is the whole reason for choosing a penetrant over a film. The maker of the product we use gives a coverage range per gallon that depends on how porous the surface is, and very dense brick takes less than soft brick. We work within that range, keep track of how much each face has taken, and record it in the job notes so the next treatment can be planned from real figures.

What the treated brick looks like

Once cured, a penetrating treatment is meant to leave the chimney looking much as it did before. The product's own literature describes little or no gloss and no change to natural color or texture, while noting that dense surfaces can darken slightly and that existing stains may become more visible. BIA adds that a noticeable sheen after treatment can mean the wrong product or poor application. The trial area is therefore judged dry, in daylight, from the ground as well as up close, and compared with untreated brick next to it before the rest of the stack is done.

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.

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.
