Our waterproofing approach, one step at a time
Repairs come before any treatment
A water repellent cannot close a crack, fill an open joint or replace a failed crown. Product data says so directly, and brick industry guidance agrees. Where water is getting in through a defect, the defect has to be repaired first.
That means open mortar joints are repointed, cracked brick is replaced and the top of the chimney is made watertight before any treatment goes on. For a chimney in Flagami, we list those repairs as separate items. If the repairs alone solve the water problem, you may decide the treatment is not needed, and we will say so.
Cleaning up after the treatment
Waterproofing leaves little debris, but preparation can. Old sealant, loose mortar from repairs and cleaning residue are collected as the work goes on. Masking and coverings come off once the product has set as its data sheet directs.
Before we leave, every scrap from the preparation goes into our bags and off the property with us. Glass and other surfaces near the chimney are checked for overspray and cleaned. If you notice anything we missed, tell us and we will come back to deal with it.
Soft, porous brick is where treatment helps most
Some brick is soft and very absorbent, either because of how it was made or because its hard outer face has worn away. Preservation guidance names that kind of brick as a case where a water repellent may be appropriate.
If the brick on your chimney in Flagami soaks up water quickly and stays dark after rain, treatment may be worth it once repairs are done. We check how the brick behaves and whether its faces are still sound enough to hold a treatment. A test area then confirms the result before the whole chimney is done.
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.

Water repellent questions before you book in Flagami
How do I know if my chimney needs waterproofing at all?
Watch the brick after rain. Faces that darken and stay dark long after the rest has dried are absorbing more water than they should. The free inspection checks that, along with the joints, top and flashing, and we tell you if treatment is not worth it.
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.
Is it worth protecting the brick on a chimney we do not use?
It weathers the same as one in use. Rain soaks its brick, and water that gets in can damage the masonry and the house around it. Repairs come first either way, and a breathable repellent can follow where the brick absorbs too much.
