Most building maintenance performed today is reactive, not proactive. A brick wall gets fixed because it is about to fall and hurt someone. Proactive repairs focus on joints rather than systems. It's the replacement of 15-year-old sealant because it has reached its designed age of useful service, or the repointing of mortar joints that have begun to erode or open up. The goal of periodic maintenance is to focus on the parts of the exterior that deteriorate at a faster rate than others. Keeping water from entering the wall or roof system will go a long way towards preserving the building. Repointing mortar in a small area could cost 100 dollars, but if left unrepaired for a decade could cause exponential damage as water penetrates deeper and deeper in to the wall, and as a result, cost exponentially more to repair. You have also increased the liability that the condition could become unsafe, and when repaired, you've lost a substantial area of original building materials.
