An old sealer gone cloudy or peeling

Some chimneys were coated in the past with a clear product that formed a film: a gloss on the brick that later clouded, whitened or began to peel. That film slows drying and can hold water behind it, and new penetrating repellents do not bond well over it. We look for signs of an old coating on Avondale brick before any product is chosen, and test a small area if it is hard to tell. If the film has to come off first, the removal is priced with its method, following the old coating maker's directions where they are known. Call (904) 920-5495 and our waterproofing pros will test your Avondale brick for free.

Avondale is one of the named neighborhoods of Jacksonville. Avondale is part of Duval County.

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

White powder on Avondale chimneys

White deposits on brick are salts carried out by water as it dries. While they keep coming, water is still moving through the masonry.

We find where the water enters and fix it, and a repellent goes on only after the deposits have stopped.

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.

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.

Cleaning the brick before treatment

A repellent has to reach the pores, and anything sitting on the surface blocks it. BIA's note is plain that the wall must be clean when the product goes on, since heavy dirt reduces penetration and shortens the life of the treatment. Chimney brick is cleaned gently: loose salt brushed off dry, dirt and growth scrubbed with a stiff fiber brush and water, and cleaning products used only where the brick maker's guidance allows them. Pressure washing at high settings can drive water deep into the brick and damage joints, and it adds days of drying before treatment can start.

FAQ

Before any sealer goes on

Do you waterproof chimneys in Avondale?

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.
