CHECK OUT THE COMPANY'S WEBSITE
What does the company offer? Some companies only provide office cleaning services, while others also do windows and other home maintenance. Companies with a detailed list of what they can provide are more likely to be high quality because that means they're complete professionals who don't just clean up after themselves but take care of all your needs.
After you've looked around on their website, it's time to reach out and give them a call (or email). Speak with someone directly to ask about their services, prices, and availability. Also get answers to any other questions that you may have such as: Is the company insured? This is important to know so you're protected in case any damage happens to your office space when they are there cleaning it up. Do you have a money-back guarantee or any other type of guarantee? What are the costs for overtime work or when a service is offered outside normal business hours? Is there anything you don't do, such as cleaning kitchen appliances and refrigerators? Do you use environmentally friendly products that won't harm your office's space in any way? This is important if you're trying to reduce your carbon footprint or operate a green company.
