How we handle chimney waterproofing in Airport North
Before you approve a treatment in Airport North, these are worth knowing.
Repointing weak joints before treatment
Mortar is usually the first part of a chimney to wear. Joints that are cracked, sandy or recessed let water into the wall, and the Brick Industry Association lists repointing incompletely filled, cracked or disintegrated joints among the repairs a repellent should not replace.
When joints need work, our crew cuts out the weak mortar and repacks it, then leaves it to cure for the time the product maker requires before waterproofing. That work appears on your estimate as tuckpointing, priced on its own, so the treatment line only covers treatment.
The brick itself matters
Every brick is made from different clay and fired differently, and those properties affect how a coating performs. Masonry guidance recommends consulting the brick manufacturer before selecting a coating whenever possible, and selecting only coatings intended for clay brickwork.
On most existing chimneys, nobody knows who made the brick. That is where the test area earns its place. We watch how your brick takes the product and what it looks like afterward, and we choose a repellent whose maker lists clay brick as a suitable substrate.
Pre-blended products over site mixes
Some repellents blend silanes and siloxanes to combine their strengths. Masonry guidance recommends using a product that is pre-blended by the manufacturer, so the proportions are the ones that were tested.
Our crew never thins, mixes or doctors a repellent on your roof. The maker's instructions for agitating the product before use are followed, and the container label matches the product on your estimate. It is a small detail that keeps the treatment behaving the way its data sheet describes.
How breathability is measured
Breathability is not a marketing word. Masonry guidance describes measuring a coating's water vapor transmission with the ASTM E96 test and recommends only coatings with a high permeability for exterior brick, along with only a small reduction in vapor transmission between treated and untreated samples.
We cannot run that test on your roof, but we can choose products whose makers publish vapor permeability data. When a data sheet does not address breathability at all, we treat that as a reason to look elsewhere. You are welcome to read the data sheet for the product we propose.

Chimney waterproofing questions from Airport North
Still deciding? These answers help, and the inspection in Airport North is free.
Can you waterproof a painted chimney?
Usually not with a penetrating repellent. Products like these are made for bare masonry, and makers say not to apply them over paint or glazed brick. We look at the paint's condition and tell you honestly whether to leave it, repair around it or plan something else.
Is it ever too hot to treat the chimney?
Yes. ChimneySaver water-base, for example, asks for surface and air between 40 and 100 degrees Fahrenheit for three hours after it goes on, and a chimney face in afternoon sun runs hotter than the air. On hot days we treat in cooler hours or on shaded faces so the product soaks in and cures properly.
