Chimney waterproofing in Galt Ocean Mile, from repairs to repellent
Siloxane and silane in plain terms
The repellents most used on brick are siloxanes and silanes, often blended. Both react with the silica in brick and mortar and change how the pores treat water. Water that would have soaked in beads up and runs off instead.
Siloxanes have larger molecules and suit most brick. Silanes are smaller and can reach further into dense surfaces. The right choice depends on the masonry in front of us and on the maker's data for each product. We name the product we propose and say why it fits your chimney.
New mortar and the waiting period
After repointing or brick replacement, new mortar needs time before a repellent goes over it. Product data sets the conditions, and new work often has to be cleaned before treatment. Treating too early can reduce the result.
Brick industry guidance also suggests waiting after repairs to see whether the water problem has already been solved. Sometimes it has, and treatment becomes optional. We explain the timing for your chimney and schedule the treatment as a separate step, so it does not get rushed onto fresh work.
Finishes that go on before treatment
Product data warns that some cementitious finishes, plaster and stucco may not bond well to a treated surface. If any such finish is planned for the chimney, it should go on first and be allowed to cure.
Tell us about any plans for patching, parging or refinishing. We sequence the work so the repellent comes last. If a repair uses a cement-based product, we allow for its cure before treatment. The estimate shows that order, so no step works against another.
A leak that appears after treatment
If water appears indoors after a chimney has been treated, the treatment is unlikely to be the path. Leaks come through openings, and a repellent is not designed to close them. The water is probably finding a crack, a joint or a gap at the top or the roof line.
Tell us promptly and leave the marks in place. We trace the path the same way as any leak. If the treatment area is involved, for example through a new crack, we explain it. The repair for the path is priced as its own item.

Chimney sealing questions, answered
Is chimney waterproofing the same as painting the brick?
No. Paint forms a film over the masonry and changes its look. A penetrating repellent soaks into the pores, keeps liquid water out and lets vapor escape. On a chimney we recommend only the breathable kind, and the estimate names the product.
Which products do you use on chimney brick?
Breathable penetrating repellents, usually siloxane or silane types, from makers that publish full technical data. The product has to list your masonry as a suitable surface. The estimate names it, so you can read its data sheet before you approve anything.
What if an earlier coating is already on the brick?
We try to identify it and test how the surface responds. Some coatings stop a new repellent from soaking in, and a glossy film may be holding moisture. If the old coating has to come off, that is a separate item with its own method and test.
