What goes into a waterproofing job in Southchase
What our pros check and why, on waterproofing jobs across Southchase.
Siloxane repellents and brick
Siloxanes react with the silica and alumina in brick and mortar and leave a water-repellent zone just under the surface. Masonry guidance recommends them when a repellent is used on exterior brick walls, and many chimney products are built on modified siloxane chemistry.
The ChimneySaver water-base repellent, for example, is described by its maker as a modified siloxane that penetrates masonry up to a quarter inch or more depending on porosity. We choose a product for your chimney by its listed substrates and data, then write its name and chemistry into your estimate so nothing is left vague.
Treating a test area first
Brick varies from kiln to kiln and mortar from batch to batch, so product makers and masonry guidance both recommend a test area before general application. The Brick Industry Association suggests at least ten square feet at a representative spot, left to cure and then checked.
On a chimney, we choose a face you can see and one that represents the rest of the masonry. When the test cures, we look at the appearance and how water behaves on it. If you are not happy with the look, we stop there and talk through other options before treating anything else.
The cap keeps rain out of the flue
A chimney without a cap takes rain straight down the flue. That water ends up in the firebox, on the damper or in the smoke chamber, and it has nothing to do with the brick faces a repellent treats.
When water shows up inside the fireplace, we check the cap before anything else. A missing or damaged cap is written up as its own item. Waterproofing the outside of the chimney is worth doing only when the water problem is really absorption through the masonry.
Replacing damaged brick first
Brick with spalled faces or cracks running through the face cannot be sealed back into shape. Masonry guidance lists removing and replacing those units among the repairs to complete before any repellent is applied.
Our pros mark every damaged brick during the inspection. Replacement brick is matched as closely as we can in size and color, set in fresh mortar and given time to cure. Only then does the chimney get its treatment, so the repellent is protecting sound masonry instead of covering a broken face.

Asked in Southchase about chimney water repellent
Short answers from our chimney team in Southchase. Call for anything not covered here.
Does the 72-hour 10% discount apply to waterproofing?
Yes. Any service booked within 72 hours after your free inspection is 10% off, and chimney waterproofing qualifies, including any repairs on the same estimate. Mention it when you book and we will show the savings in writing.
Can I use a clear sealer from the hardware store?
We would ask you to wait for our look first. A can on the shelf might be a breathable penetrant or a film former, and some are made for driveways or decks, not brick. A film sealer on a chimney is much harder to undo than to avoid, and our inspection costs nothing.
