With Spring just around the corner, many Property and Facilities Managers will be faced with the inevitable challenge of cleaning up the exterior of the building after a cold, salty winter. Aside from the parking lot and landscaping, two large annual budget items, there are three key areas to focus attention in order to bring your commercial building's exterior appearance back to life.
Concrete: After several applications of salt and dirt over the course of the winter, concrete can look worn, filthy and chalky.
From sidewalks to dumpster pads to the building facade, each of these areas typically need a thorough cleaning to remove the dirt, debris and layers
of salt. Chemicals, even the "safe" products, contain chlorides which are mildly acidic and can attack the bonds that hold concrete together. This
increases the pore size and can allow water into the concrete and exacerbate the freeze/ thaw cycle. Hiring a qualified company to pressure clean these
areas (and make repairs to damaged concrete) is important as it removes the harmful contaminants from the surface and improves the appearance.
Metal: Every commercial building has an assortment of metals on the exterior of the building. Whether it be the monument sign, handrails, light bollards, entrances (doors and side light window frames) or the window mullions - each anodized or painted aluminum, bronze or stainless steel finish is affected by the harsh winter. Metal gradually destructs from a chemical reaction to its environment. Anodized aluminum starts to form pitting or shows signs of degradation, bronze becomes oxidized and stainless steel begins to rust. All resulting from the chemical reaction of airborne pollutants and the application of salt products. These surfaces need attention come Spring. A qualified contractor can clean each of the metal surfaces and apply a barrier (wax) to protect the metal from further harm. In extreme cases where the metal has been damaged beyond a simple cleaning, such as the chalking of dark anodized aluminum window mullions, a quality contractor can clean and apply a clear synthetic coating to bring the mullions back to life and protect between services.
Glass: Window cleaning is a routine maintenance item that most every building has budgeted year after year. However, the glass panes at many buildings need more attention than this routine cleaning. Many buildings' irrigation systems repeatedly spray water onto the first floor windows leaving calcium and magnesium deposits known as lime scale. This film is difficult to remove and, left untreated, can cause irreparable harm to the glass. The longer the film sits on the surface, the more difficult it is to remove. An annual or semi-annual professional removal of this film is recommended to keep this film from causing permanent damage.
By focusing attention to these three key areas, a Property Manager, Facilities Manager or property owner can improve the appearance of the exterior of their commercial building which aids in both tenant relations and the ability to lease the property in a timely manner.
