Keeping rain from soaking into chimney brick
A chimney that runs down the outside wall
A chimney on the outside of the house exposes brick from the ground to above the roof. Waterproofing may cover the full height or only the part above the roof line. Lower courses near the ground often face different problems, such as splash and soil contact.
We look at the whole chimney and explain which parts would benefit most. The lower courses may need soil pulled back or drainage improved rather than a coating. The estimate sets out the height and faces included, so the scope is clear.
Reaching the chimney for treatment
Treating a chimney means reaching every face to be treated, usually from the roof and sometimes from ladders or staging on the ground for an outside chimney. Access depends on the roof pitch, height and surface.
Mention anything that sits under the chimney, such as a patio, flower beds or a skylight, so we can plan where ladders stand. Gates, dogs and parked cars matter too. We sort out access before the application day, so the dry weather window is not spent setting up.
Why the firebox is left alone
The firebox and the inside of the flue face fire and hot gases, not rain. Masonry water repellents are not made for that exposure, and applying them there serves no purpose. Those surfaces have their own repair products.
If you want the inside of your fireplace or flue looked at, that is a different service. We can note what we see during the waterproofing visit. The treatment itself stays on the outside faces above the roof, or down the outside wall where agreed.
Soft, porous brick is where treatment helps most
Some brick is soft and very absorbent, either because of how it was made or because its hard outer face has worn away. Preservation guidance names that kind of brick as a case where a water repellent may be appropriate.
If the brick on your chimney in Nurmi Isles soaks up water quickly and stays dark after rain, treatment may be worth it once repairs are done. We check how the brick behaves and whether its faces are still sound enough to hold a treatment. A test area then confirms the result before the whole chimney is done.

Before you approve waterproofing in Nurmi Isles
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.
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.
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.
