Keeping rain from soaking into chimney brick
Only the outside faces are treated
Chimney waterproofing treats the exterior masonry. It does not go inside the flue, onto the smoke chamber or into the firebox. Those surfaces face heat and combustion gases and need products made for that, which is a different job.
Inside the house, brick on the chimney breast is also left alone. Interior masonry is not exposed to rain, and treatments for exterior brick are not chosen for indoor use. The estimate names the faces included, so there is no doubt about where the product goes.
Water-based and solvent-based products
Repellents come in water-based and solvent-based forms. The carrier affects the conditions for application, the odor and the regulations the product must meet. Water-based products tend to have less odor, which helps when the house is occupied.
We choose the carrier with your household and the masonry in mind, within the product's data. Tell us if odor is a concern, for example with young children or someone sensitive at home. We explain what the chosen product is like to live with during application.
Deciding when to renew a treatment
Whether a treatment needs renewing is best judged by how the brick behaves, not by a fixed interval. If water still beads and runs off after rain, the treatment is still working. If the faces darken and hold water again, it is fading.
We can check this on a maintenance visit, sometimes by wetting a small area to see how it responds. If renewal makes sense, the same preparation applies, including any repairs. The written record from the first treatment tells us what product is already on the brick.
What chimney sealing should mean
When people ask for their chimney to be sealed, they usually want the brick to stop getting wet. The right answer is rarely a sealing coat. It is repairs where water gets in, then a breathable repellent where the brick absorbs too much.
We explain that difference at the start, because it changes what you are buying. The estimate uses plain terms: which repairs, which product, which faces. That way chimney sealing means a defined job with clear limits, rather than a promise to make the brick waterproof.
Written into a waterproofing proposal
- Brick faces checked for flaking or cracks
- Cap or open flue noted at the top
- Named penetrating repellent and its data sheet
- Base of an outside chimney checked
Before you approve waterproofing in Pembroke Park
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.
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.
Can I apply a chimney sealer from a hardware store myself?
You can, but read the product data first. Some store products form films that trap moisture, and every product needs repairs done beforehand and glass and plants protected. Working at height on a roof is the other risk. The free inspection tells you what the chimney needs either way.
