They were very knowledgeable and very professional.
They were knowledgeable and helpful.
They were super professional, and nice. It was great having them during a traumatic time.
Very nice and helpful, but never on time and didn't finish part of what they said they would do.
The vocabulary they used while working was a lot of cursing; I was upstairs, and I could hear it from the basement. It could have been more professional. They need to be more customer-friendly; it was unprofessional.
