What goes into a waterproofing job in New Malibu
Practical points from our waterproofing crew in New Malibu.
Siloxane repellents and brick
Siloxanes react with the silica and alumina in brick and mortar and leave a water-repellent zone just under the surface. Masonry guidance recommends them when a repellent is used on exterior brick walls, and many chimney products are built on modified siloxane chemistry.
The ChimneySaver water-base repellent, for example, is described by its maker as a modified siloxane that penetrates masonry up to a quarter inch or more depending on porosity. We choose a product for your chimney by its listed substrates and data, then write its name and chemistry into your estimate so nothing is left vague.
Wind-driven rain and cracked masonry
Rain that falls straight down behaves very differently from rain driven sideways by wind. Masonry guidance notes that the effectiveness of penetrating repellents is limited under wind-driven rain, especially where there are cracks or open joints.
That is one more reason we repair joints and cracks before treating. A sound chimney wall with a breathable repellent sheds far more of that sideways rain than a cracked one with a coat over it. The repairs do the heavy lifting, and the treatment helps the masonry between them.
Damp around the chimney in the attic
Damp framing or stains beside the chimney in the attic usually point to water at the roof line. That is most often flashing or the joint between the chimney and the roof, not the brick faces above.
We check the attic side and the roof side together. If the flashing or counterflashing is the problem, it is a flashing repair. If the brick above the roof is soaking up water and feeding it down inside, a repellent may be part of the answer. You get the reasoning, not just a recommendation.
What you have when the job is finished
At the end of a waterproofing job, you have a clean site, treated masonry and paperwork that explains it. That includes the product name and data sheet, the faces treated, the date and any repairs completed before treatment.
We walk you through what was done and what to watch for. If you have questions later, call the same local team. The record also makes future work easier, because anyone who touches the chimney afterward can see exactly what is in the masonry.

What people in New Malibu ask about chimney sealing
Short answers from our chimney team in New Malibu. Call for anything not covered here.
How soon can your team come out to New Malibu?
Same-day service is available when our schedule allows. Call early, describe what you see and we will offer the first available time for a free inspection. The treatment itself is booked around the weather and any cure times.
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.
