Sean O., Office Cleaning in Denver, CO

5★★★★★ - "I really liked how KO made me feel like everything was included. The other companies I got estimates from had a "base" price and then you had to pay for each thing on top of that. I felt nickle and dimed. KO didn't do that. Jacob came to my house for an estimate and let me know that it was going to get cleaned whether it was dirty from construction or regular use. Even with a miscommunication about the contract, he was able to start the same day and got things looking great in a timely matter. I would hire this company again in a heartbeat."
