Algae and moss cause discoloration of the facade and masonry. A high-pressure cleaner is often used to clean the facade, but caution is advised: bricks, for example, are harder on the outside than in the core. There is a good chance that you will spray that hard layer off. The result is a clean, but more porous surface that gets dirty more quickly. That is why we treat the facade with a water-repellent product after removing algae and moss.
We advise you to have us check your masonry twice a year (after the winter and after the summer) to see if it is still hard enough. Joints on the south and west in particular are heavily loaded by rain, wind, heat and cold. Joints that crack and crumble can cause problems, such as mold and leaks.
Most walls have so-called open butt joints at the top and bottom. These butt joints ventilate the cavity. There are also usually small grates for ventilation of the crawl space. We advise you to have us check about twice a year whether the ventilation openings are not clogged.
Concrete requires virtually no maintenance, but you can clean it if it is heavily soiled. We will of course also take care of this work for you.
The grout needs to be replaced if it is loose or falling out, if moss or algae grows on it, or if the grout becomes darker in color due to the action of moisture. Façades on the south and west in particular suffer from weather influences and are often the first to show signs of aging. If necessary, we can replace your jointing.
