Questions to ask about a sealing proposal
A proposal to seal or waterproof a chimney should answer a few basic questions. These help you check any quote, including ours.
If a quote cannot answer these, it is worth asking why. Our estimate addresses each in writing, and we are glad to go through them in person.
- Does the product penetrate or form a film
- Which repairs will be done before it goes on
- Will a test area be done first
- What happens to glass, roofing and plants nearby
A leak that appears after treatment
If water appears indoors after a chimney has been treated, the treatment is unlikely to be the path. Leaks come through openings, and a repellent is not designed to close them. The water is probably finding a crack, a joint or a gap at the top or the roof line.
Tell us promptly and leave the marks in place. We trace the path the same way as any leak. If the treatment area is involved, for example through a new crack, we explain it. The repair for the path is priced as its own item.
Two chimneys, two separate assessments
If your house has two chimneys, each one is assessed on its own. They may be built from different materials, face different weather and carry different repair histories. One may need treatment while the other does not.
The estimate lists each chimney separately, with its own repairs and its own treatment line if it needs one. You can then decide on each. Doing both at once saves setting up access twice, but only if both genuinely need the work. We will not pair them just to fill a visit.
What happens on the application day
On the application day, we confirm the forecast, check that the masonry is dry and set up access. Glass, metal, roofing and plants in range are covered or masked. Cars and furniture have been moved.
The product then goes on, face by face, by the method its data sheet sets. Overspray is dealt with as the work proceeds. When the product has set enough, coverings come off and the area is cleaned. We go through what was treated and hand over the written record.

Asked often about sealing chimney masonry
Is chimney waterproofing the same as painting the brick?
No. Paint forms a film over the masonry and changes its look. A penetrating repellent soaks into the pores, keeps liquid water out and lets vapor escape. On a chimney we recommend only the breathable kind, and the estimate names the product.
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.
Does a metal flue inside a framed box need waterproofing?
Not with a masonry repellent. A framed chase has no brick to treat. Its water problems come from the cover at the top, the collar around the pipe and the siding or stucco joints, and we look at those instead.
