Breathable treatment for chimney brick in Progresso Village

Mortar joints ready for treatment

Mortar is part of the surface the repellent protects, and it has to be sound. Joints that are soft, sandy, cracked or recessed let water in regardless of any treatment. Brick industry guidance lists repointing such joints among the repairs to finish first.

We check the joints across each face. Where repointing is needed, it is a separate item priced by the extent of the joints. The new mortar is allowed its curing time before treatment. If only a few joints are affected, the repair can be local rather than the whole chimney.

Patches that take treatment differently

A chimney that has been repaired over the years carries brick and mortar of different ages and makes. Replacement brick may be denser or more porous than the original. Newer mortar may absorb differently from older joints.

Those differences can show after treatment, with some areas darkening more or shedding water differently. The test area should include patched sections as well as original ones. We point out the patches during the inspection and explain what to expect on each. If a patch is failing, its repair comes before the treatment.

The scope for a chimney in Progresso Village

A waterproofing scope for a chimney in Progresso Village is written for that chimney, not copied from a price sheet. The masonry type, the faces exposed, earlier repairs and the state of the top all change what the job needs.

We explain the reasons behind each line. If a line depends on something we could not see without a test area, we say so. That way the scope you approve describes the actual work, and any change after the test comes to you as a clear, separate item.

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.

Asked often about sealing chimney masonry

How do I know if my chimney needs waterproofing at all?

Watch the brick after rain. Faces that darken and stay dark long after the rest has dried are absorbing more water than they should. The free inspection checks that, along with the joints, top and flashing, and we tell you if treatment is not worth it.

Why does the treatment start with a test area?

Product makers ask for one on each surface. It shows how the brick absorbs the product, whether the look changes and how much material the faces take. The test includes patched areas, and you see the dried result before the whole chimney is treated.

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.
