Corporate information

The starting point of our work was the cleaning of air conditioning ducts in 1983. What surprised me during the duct cleaning at that time was the copious amounts of pigeon droppings around the rooftop air intake. The reality was that the pigeon droppings were sucked straight into the air conditioner. The owner of the building asked me to do something about it, and the public health center pointed out that it was a sanitary hazard. At that time, I tried using pest control tools that were available in the market, but they weren’t very effective. discover. It was one of the items, “Doves have organs that sense geomagnetism in their bodies.” Using this as a hint, I discovered that if you use a magnet to disturb the magnetic field, the pigeons will not stick to it. We have developed the world’s first bird stopper that uses a magnet to prevent birds from flying. From the point of view of animal welfare, this method is the most peaceful solution that can prevent birds from flying without killing or injuring them. Currently, we have a number of devices for various situations, but we do not want to sell products that tend to be irresponsible. Rather than that, we will look at the site, select the best method and make a proposal, in return we will take full responsibility. This is the so-called “guarantee of effectiveness through responsible construction”. What we value in delivering our services. These are the daily “effort” to improve services, the “speed” to respond quickly, the improvement of “satisfaction” to solve problems and deliver smiles, “Kind heart” that provides optimal proposals and construction according to the issues of the customer. We, ESQ, practice the provision of these four values ​​and aim to create a city that is friendly to people, animals, and the environment. “I want to solve people’s problems.” “I want to make many people happy.” We will continue to challenge new fields, aim for further expansion, and contribute to society.
