Repairs, preparation and a named repellent
Covering glass, roof and garden before spraying
Repellents are made for masonry, and they should not land on anything else. Siloxanes and silanes can bond with unprotected glass. Overspray can mark roofing, metal, paint and cars, and it can harm plants below the chimney.
Before we start work at a home in Flamingo Park, we cover or mask windows, skylights, roofing near the chimney and anything else in range. We ask you to move cars and outdoor furniture away from the chimney. Any overspray is cleaned promptly as the product instructions describe, and the area is left as we found it.
Fine separations along the mortar edges
Sometimes the mortar is intact but has pulled away slightly from the brick, leaving hairline gaps along the joints. Water can wick through those gaps even when the brick itself is sound.
Brick industry guidance describes surface grouting of such separations as a repair to do before any clear coating. We look closely at the joint edges on each face. Where separations are present, the fix is listed separately. A repellent alone is not the right tool for them, because the gaps are wider than the pores it works in.
The written record of the treatment
When the work is finished, you receive a written record of it. It names the product, the faces treated, the repairs done beforehand and the date of application. It also notes any area left untreated and why.
Keep it with your home papers. Before anyone applies another product later, the record tells them what is already on the brick. That matters, because some treatments do not combine well. It also helps judge, down the line, whether a renewal is due.
What to watch after rain
You can check a treated chimney yourself from the ground. After rain, look at how the brick dries. Treated masonry usually sheds water and dries evenly. Patches that stay dark long after the rest has dried may mean water is getting in there.
Note which faces and areas behave differently. Uneven drying can come from a patch the treatment missed, a repair that took the product differently or a new crack. Mention what you see at your next visit, or call if it changes quickly.

What people ask before sealing a chimney
Should a planned new roof go on before the chimney is treated?
Usually, yes. Finishing the roof and the chimney flashing first avoids roof work marking treated brick and overspray marking new roofing. Tell us your roof plans, and we schedule the treatment to follow, with the new roofing protected during application.
How long does chimney waterproofing take from start to finish?
It depends on the repairs needed first, the curing and drying time and the weather. The application itself is usually the shortest step. The estimate sets out the stages in order, and a dry weather window decides the final date.
Will the treated brick still let moisture out?
With a breathable repellent, yes. It keeps most liquid water from soaking in while letting water vapor leave through the face. That matters on a chimney, because moisture reaches the masonry from inside as well, and a sealing film could hold it in.
