AITA for wanting to get a new cleaner?

I have been using her services for years, but the quality has been going down. We are also sorta "friends" so it makes things awkward. The situations that stick out the most, she watched over my furniture delivery & put it together. But the furniture pieces didn't match & she didn't pickup on it so I had to get things reshipped. There's been more times recently where she's been late with services, always due to last minute stuff. She's been very helpful in the past & I'd hate to damage our relationship but I just feel irritated.WIBTA if I fired her?
