Do the Capabilities of your Commercial Cleaning Company Meet your Needs

Posted on by blogger

Hiring a commercial cleaning company for your office is the best way to ensure that the areas where your employees work and your customers visit for presentations and meetings is neat, clean, and professional. Whether you need someone for routine cleaning or occasional deep cleaning of offices or specialized areas, you should select the right company based on their experience. If your company has a medical lab, a clean room, industrial equipment, or other special needs, you need professionals who know how to clean the area without disturbing your specialized equipment. In the case that your company has an in-house maintenance staff to handle some regular cleaning duties, you also want a cleaning company that is flexible enough to pick up the slack and perform deep cleaning when needed.

Does the Commercial Cleaning Company Offer Office Cleaning Services?

In an office, a commercial cleaning crew concerns themselves with six main areas: the floor, surface, restrooms, upholstery, trash, and kitchen. They will make sure that your floors are swept, vacuumed, and for hard floors mopped and polished on a regular basis. They will also make sure that services such as windowsills, desktops, office equipment, conference tables, wood chairs, and other office furniture are free of dust that can make the area seem uncared-for and provoke allergies. The cleaning crew will also clean and deodorize bathrooms, while refilling supplies, and keep other areas such as kitchens and lunchrooms clean and sanitary, too. They will also handle trash removal from offices and other designated areas. When hiring a general cleaning company, your concern is that they are licensed and bonded and use experienced, thorough workers who do the job with pride.

Do They Have Experience with Special Needs Cleaning

For companies with labs and other specialized facilities, a commercial cleaning crew takes care of all the regular aspects of office cleaning, but must exercise special care due to the expensive precision equipment there. In addition, the crew must observe any special procedures.

For example, when cleaning medical facilities, the crew must be even more fastidious in cleaning and sanitizing to fight cross-contamination and avoid any toxic chemicals. As a result, a crew cleaning a medical facility might do the job with hospital strength chemicals that are green, vacuums with high-quality HEPA filtration systems, and frequently changed microfiber cloths. Employees of the commercial cleaning company have extra training to ensure cleanup of blood that is safe for them and for patients and in compliance with OSHA disease prevention regulations.

Other types of industries have their own special needs that pose challenges for commercial cleaning companies. Most industries, whether you are talking about automotive dealerships, banks, daycare and preschools, or computer labs, may have OSHA regulations or industry best practices that the cleaning company needs to follow. In hiring cleaning professionals for your specific type of facility, you need a company with specialized experience in the industry that is familiar with these requirements and who will meticulously follow your instructions for what must be clean.

Will They Schedule Occasional Deep Cleaning?

Whether you have a commercial cleaning company or an internal maintenance staff to handle regular cleaning, you may need to hire professionals to handle major projects such as floor stripping and waxing, window cleaning, or upholstery and carpet cleaning. Many firms that handle routine cleaning can also schedule these additional services for you to make sure that your facility is both surface clean and deep clean.

Hiring a commercial cleaning company that can meet the range of needs you have will keep you satisfied and your work space safe and clean.

Reasons Your Computer Chairs Break

Posted on by blogger

Sadly, its not uncommon to have computer chairs snap under you. You might not even be that heavy, but chairs just arent made as well these days! Remember back when they were all metal? Those suckers withstood anything. These days, plastic is all youll find in most computer chairs. Overweight people tend to have even more problems since chairs often last only a few weeks before something breaks.

While you can keep using the chair without an arm or even if the back cracks and ends up at a weird angle (yes, this happens to many of us!), once the support column or one of the wheels or base legs goes, youre pretty much hooped. Many people cobble together Frankenchairs, made from a base that still functions with a seat that is still intact, just to save a bit of money. It might seem silly, but if you have computer chairs break on you every couple of months, this is what happens.

So, why do your chairs break? Here are three main reasons:

1. Its not built for weight. Most computer chairs are designed to withstand 150-200 lbs. So, if you weigh anything over that, your chair isnt going to last very long. Thats why you might want to look at computer chairs for overweight people, which can be rated for up to 500 lbs.

2. The material is poorly made. Unfortunately, there arent many high standards in the world of office chairs. Overweight people have discovered that plastic simply isnt designed to withstand much weight . . . it twists and bends and eventually cracks under the stress. These chairs are often stamped out of low cost plastic, which is not sturdy enough.

3. You move too much. When a computer chair is working properly, it will roll smoothly over the floor. However, poorly built chairs cant hold up to the weight. They will sink down, essentially crushing the wheels against the caps and the wheels wont roll. When this happens, you will end up jerking the chair to move it and that puts extra stress on the already fragile joints.

Often its a combination of these three factors that causes a computer chair to give way. You will want to make sure that you choose your chair very carefully. There are a number of designs in computer chairs for overweight people that will hold more and resist more action. Even if you arent obese, choosing a sturdier chair can be a good investment in the long run.
