Waterproofing work for chimneys in Lauderdale-by-the-Sea

A test area comes first

Product makers ask for a small test area on each surface before the whole chimney is treated. It shows how the masonry absorbs the product, whether the appearance changes and how much material the surface takes.

The test should include any earlier patches or repairs, because those can behave differently from the original brick. On a chimney in Lauderdale-by-the-Sea, we apply the test with the same method we would use for the full job. If the result is not what you want, for example a darker look, we talk about it before going further.

Gloss on the brick points to a film

If a chimney has a glossy or wet look after an earlier treatment, it may have been coated with a film-forming product. That shine can be a sign that the coating is sitting on the surface rather than in the pores.

We check any earlier treatment before recommending another. A film over the brick can prevent a penetrating repellent from working and may be trapping moisture. The findings describe what we see, and removing an old coating, if needed, is a separate step with its own test.

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.

When the brick maker is known

Brick industry guidance suggests consulting the brick manufacturer before choosing a clear treatment. On an existing chimney, the maker is usually unknown, and the brick may have come from several sources over the years.

If you do know, from building papers or a stamp on spare bricks, tell us. It can help with the choice. If not, the test area does the same job in practice. It shows how this particular brick takes the product and how it looks afterward.

Chimney sealing questions, answered

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.

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.

Is it worth protecting the brick on a chimney we do not use?

It weathers the same as one in use. Rain soaks its brick, and water that gets in can damage the masonry and the house around it. Repairs come first either way, and a breathable repellent can follow where the brick absorbs too much.
