Waterproofing work for chimneys in The Roads
Repairs come before any treatment
A water repellent cannot close a crack, fill an open joint or replace a failed crown. Product data says so directly, and brick industry guidance agrees. Where water is getting in through a defect, the defect has to be repaired first.
That means open mortar joints are repointed, cracked brick is replaced and the top of the chimney is made watertight before any treatment goes on. For a chimney in The Roads, we list those repairs as separate items. If the repairs alone solve the water problem, you may decide the treatment is not needed, and we will say so.
Clean and dry masonry before treatment
A repellent works best on clean, visibly dry and absorbent masonry. Dirt, growth and old residues can stop it soaking in. Excess moisture in the brick reduces how deeply it penetrates and shortens how long it lasts.
Cleaning is chosen for the masonry, using the gentlest method that works. Harsh chemicals or high-pressure washing can damage brick and mortar. After cleaning, the surface needs time to dry before treatment. We explain the cleaning step and the wait in the estimate for your home in The Roads, so the schedule makes sense.
The roof junction comes before treatment
Where the chimney meets the roof, water is handled by flashing, not by the brick. If the flashing is loose, rusted or cut short, water gets in there, and treating the brick above does nothing about it.
We check the roof junction while preparing a waterproofing scope. If it needs work, that goes on the estimate as chimney flashing repair, a separate item. Treating the faces while the junction leaks would leave the main water path open. Once the flashing is sound, the brick above it can be judged on its own.
People and pets during application
During application, keep children and pets away from the area around and below the chimney. Spray drift can travel in a breeze, and the product should not land on skin or fur. We mark off patios and paths under the chimney.
Close windows near the chimney while we work, and keep doors on that side shut. If anyone in the household is sensitive to odors, tell us in advance. Many water-based products have little smell, and we can tell you what to expect from the one we plan to use.

Chimney sealing questions, answered
Can a repellent close cracks in the brick or the joints?
It cannot. Penetrating repellents work inside the pores, and anything wider than a fine hairline is beyond them. Open joints are repointed, cracked units replaced and gaps sealed before treatment. We list those repairs separately, with the reason for each.
What about a chimney finished in stucco?
Some repellents list stucco as a suitable surface and others do not. Cracks, hollow areas and gaps around trim come first, because a treatment cannot bridge them. Where a different finish suits the stucco better, that work belongs to stucco repair, and we explain why.
What if an earlier coating is already on the brick?
We try to identify it and test how the surface responds. Some coatings stop a new repellent from soaking in, and a glossy film may be holding moisture. If the old coating has to come off, that is a separate item with its own method and test.
