How do I bathroom / kitchen / extension? etc.

We got a quote for a second hand front door we bought to be fitted in a new wooden frame. The carpenter who quoted for it on Monday said this:

I’ve done thousands of doors and frames over the last 20+ years. However, I don’t have a joinery shop with spindle moulder so will need to use glazing beads and door stops on a standard square frame. If you are looking for a moulded door frame I’d suggest going to a joinery shop

What does it mean?
