By Alex A. KecskesIf you own a corporate office building, you know that corporate leasing is down due to this bad economy. Your main goal this year is to fill that building with leasing businesses. You can't afford to carry a half empty building. One thing you must do is make sure your office building always looks clean, and that things like A.C. systems and lighting systems are working properly. Bird proofing your building now can save you from all sorts of problems down the line.Problem: You know from bitter experience that pest birds can create a number of problems for your building maintenance team. For one thing, bird droppings splattered all over your building's façade and glass windows can quickly ruin your building's image. And image is key when clients come looking for office space. Over time, bird droppings and nesting materials can ruin expensive A.C. units, blocking vents, freezing up fans, and clogging ducts. Bird droppings can also eat into the electrical wiring on rooftops and around signage, causing electrical shorts and possibly even a fire. Bird droppings can also block lighting and security cameras. And they can create dangerous slip-and-fall hazards on walkways and entrances that could pose a legal liability. All in all, pest birds are most unwelcome to your property. The sooner you implement an effective bird proofing strategy, the better. Solution: One of the most effective ways to bird proof office buildings is through the use of Bird Spikes. Pest birds like to gather on rooftops and parapet walls. They like the advantage of a high perch where they observe the goings on. They also like to build their nests around your building's A.C. units and other rooftop structures. Bird spikes deny birds--especially large birds like crows, pigeons and gulls--a place to land. Bird spikes are easily installed on most any roofline, parapet wall, roof structure or A.C. unit. They come in rigid U.V.-resistant unbreakable polycarbonate or high strength, durable stainless steel. Stainless steel spikes are available in 3-, 5- and 8-inch widths to accommodate various bird species. The less expensive plastic spikes come in 3-, 5- and 7-inch widths. Bird spikes have blunted tips so they won't harm birds and maintenance crews. Properly installed, bird spikes are barely visible on your rood. They come in a non-reflective metal finish and a variety of colors, including white, tan, gray, black, brown, brick red and crystal clear. Like all bird deterrents, it's best to install bird spikes before birds arrive for spring. Take this preventive bird-proofing step and you won't have to hire expensive cleaning and maintenance crews to keep your office building looking sharp and working at peak efficiency.
