Repairs, preparation and a named repellent
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.
Painting treated masonry later
If there is any chance you will paint the chimney later, tell us before treatment. Paint may not stick well to masonry treated with a repellent. Product makers suggest testing paint adhesion first, and sometimes a rinse and drying period helps.
It is easier to decide now. If painting is planned, it may make sense to skip the repellent and choose a paint system suited to masonry instead. We explain the trade-offs so you do not end up with a treatment that complicates the next job.
Choosing a product with a track record
Brick industry guidance recommends products that have performed well on similar brick, in similar exposure, over a meaningful period. A new or untested product may look fine at first and behave differently later.
We use products whose makers publish full technical data, including the surfaces they suit and their limits. Our estimate names the product, and its data sheet is yours to read. If you have a product in mind, tell us, and we will explain whether it suits your chimney.
The written record of the treatment
When the work is finished, you receive a written record of it. It names the product, the faces treated, the repairs done beforehand and the date of application. It also notes any area left untreated and why.
Keep it with your home papers. Before anyone applies another product later, the record tells them what is already on the brick. That matters, because some treatments do not combine well. It also helps judge, down the line, whether a renewal is due.

Common questions on treating chimney brick
Is there a discount on chimney waterproofing in Durrs?
Yes. Waterproofing you approve within 72 hours of the free inspection at your home is 10% off. The estimate stays as written during that window, so there is time to read the product data and ask questions.
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.
Will the treated brick still let moisture out?
With a breathable repellent, yes. It keeps most liquid water from soaking in while letting water vapor leave through the face. That matters on a chimney, because moisture reaches the masonry from inside as well, and a sealing film could hold it in.
