New internal doors (metal door frames. - Carpentry job in Glasgow, Lanarkshire

Job description

Hi there. we currently are looking at changing our internal doors. the house we live in is an old council house and has metal door frames apparently with the hinges being built into them and then attached to the door. we did get a quote from a door company but they didn't seem too keen on attempting the job. they did say that the easiest way would be to either grind off the doors or simply reattach the new door to the existing hinge but this wouldn't give a nice finish as the hinges are horrible. unfortunately the amount of doors required to change is around eight doors and I believe all but 1 have the metal frames. can anyone advise or give a quote on either grinding off the door hinges to allow us to refit new hinges and doors or provide any other solutions.

thanks a lot.
