Stone can be an excellent exterior material for a professional office building or a residential structure. If your building is in the middle of the city, a stone exterior or facade can help separate it from all of the steel and glass structures nearby. In more suburban business parks, stone can be a nice touch to help your building complement its natural surroundings better.
While stone looks great when it’s first installed, it won’t stay that way without proper care. Environmental factors, weather and human-caused problems can quickly lead to stone faces that are stained, broken or corroded. Make sure this doesn’t happen to your building, and if it does ensure you nip it in the bud. Here are a few things that everyone should know about maintaining their exterior stone.
Like glass, metal and any other part of you building, stone is vulnerable to the the elements. Rain and air pollution are a few of the leading causes of trouble for stone building exteriors.
Air and rain both carry a number of pollutants and minerals that can damage stone over time. For example, chemicals such as sulfates that are carried to the stone from air and rain can create acidic mixtures that slowly eat away at the stone. Left alone, this corrosion can damage both the appearance and function of your stone exterior, exposing other parts to the elements.
Similar issues occur with salts in the rain or the stone itself, where untreated or improperly installed stone eventually becomes stained and damaged by salt. Water penetrates the stone, then over time, brings the minerals to the surface, ruining the clean appearance of your building.
Snow and ice also cause problems for stone. If the stone has not been sealed correctly or maintained, ice can get into cracks and behind the stone where it freezes and thaws, moving the stone and allowing water into the metal behind it. This can lead to metal corrosion as well. Additionally. exterior metal that’s improperly maintained can also create problems for your exterior stone by leading minerals such as rust onto the stone and causing long-term damage.
Water is a major culprit of stone damage.
Other common stone problems are related to human error. This includes everything from improperly installed panels that allow water in and poor caulk work to graffiti. Drainage problems can also play a major role in stone damage, especially if the drainage system is working improperly and leaking water onto the stonework.
The key to maintaining a stone exterior is to strike early, maintain the building regularly and protect it from future damage. Some of the most damaging and expensive repairs for exterior stone come from people neglecting their maintenance duties and allowing a small stain to corrode an entire stone.
Instead, everything from limestone to granite veneers should be washed and restored regularly.
