Our waterproofing approach, one step at a time
Stains from rust or copper
Rust from a cap or old flashing, or green runoff from copper, can stain the brick below. A repellent applied over those stains may make them harder to remove later, because treated masonry holds stains differently.
We clean stains before treatment where the masonry allows it, using methods suited to the stain and the brick. The source of the staining is noted, because a rusting cap will keep staining the new work. If the metal needs attention, that is its own item.
A chimney that runs down the outside wall
A chimney on the outside of the house exposes brick from the ground to above the roof. Waterproofing may cover the full height or only the part above the roof line. Lower courses near the ground often face different problems, such as splash and soil contact.
We look at the whole chimney and explain which parts would benefit most. The lower courses may need soil pulled back or drainage improved rather than a coating. The estimate sets out the height and faces included, so the scope is clear.
How a waterproofing job is scheduled
A waterproofing job often runs in stages. Repairs come first, then time for new mortar to cure. Cleaning follows, then time for the masonry to dry. The treatment goes on last, in a dry weather window.
We set out those stages in the estimate, without inventing exact dates, because weather and curing decide them. You know what happens at each step and why. If you would like the stages spread across separate visits for cost or convenience, we can plan it that way.
Avoiding hot brick during application
Product data warns that very hot surfaces reduce penetration, because the carrier evaporates before the repellent soaks in. Brick in direct sun can get hot enough for this to matter, even when the air feels mild.
We plan application for a time of day when the faces are within the product's limits. That may mean starting early or treating faces as they come out of the sun. If the surfaces are too hot, we wait rather than apply a product that will not penetrate properly.

Asked often about sealing chimney masonry
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.
Why does the treatment start with a test area?
Product makers ask for one on each surface. It shows how the brick absorbs the product, whether the look changes and how much material the faces take. The test includes patched areas, and you see the dried result before the whole chimney is treated.
Does waterproofing cover the inside of the flue or the firebox?
No. The treatment goes on the outside masonry only. The flue, smoke chamber and firebox face heat and combustion gases rather than rain, and masonry repellents are not made for that exposure. Interior problems belong to a different service, and we can note what we see.
