How we waterproof chimney masonry
A water repellent is not a waterproof coating
The two terms get used as if they meant the same thing. They do not. A waterproof coating seals the surface against liquid water and water vapor alike, and it is usually opaque. A water repellent keeps liquid water out of the masonry while still letting vapor pass.
Chimney waterproofing, done properly, means the second kind. Brick has to be able to dry, and a coating that seals it tight can hold moisture inside. When we talk about treating your chimney, we mean a breathable water repellent, and the estimate names the product so there is no confusion.
How the repellent goes on
Product data sets the application method. For many penetrating repellents, that means a low-pressure spray that wets the masonry without turning the product into mist. Some call for the surface to be flooded and a second pass applied while the first is still wet.
Small areas may be done by brush or roller when the product allows it. We follow the method in the data sheet for the product we name, using the same method on the test area. The written record notes how the product was applied.
Metal parts at the chimney
A chimney carries metal: the cap, the flashing, straps and fasteners. A masonry repellent is not made for metal, and overspray can leave residue on it. Some metal surfaces are painted, and residue can mark the paint too.
We mask metal parts close to the faces being treated. If a metal part is rusting or loose, we note it, because a failing cap or flashing will need its own repair. The treatment is applied to the masonry only, as the product data intends.
Two chimneys, two separate assessments
If your house has two chimneys, each one is assessed on its own. They may be built from different materials, face different weather and carry different repair histories. One may need treatment while the other does not.
The estimate lists each chimney separately, with its own repairs and its own treatment line if it needs one. You can then decide on each. Doing both at once saves setting up access twice, but only if both genuinely need the work. We will not pair them just to fill a visit.

Waterproofing answers for homes in Imperial Point
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.
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.
What does the workmanship warranty cover on a treatment?
Our warranty applies to the workmanship, meaning the cleaning, masking and application set out in the written record. Faces outside the agreed scope, and later cracks from other causes, fall outside it. Ask before you approve how a future problem would be looked at.
