Yes definitely prehung. Unless you are a skilled trim carpenter it is a pain in the a** to hang doors.

My husband is a skilled carpenter and we still bought pre-hung doors.

Thank you both. I just reached out to my local lumber / door company and made sure he's getting the estimates for pre-hung!!

We are replacing all of our interior doors as the original 1959 doors have seen better days. Our installer looked at all of our jams and only recommended replacing the ones where it is a double door (longer story and I am too lazy to type it out). So that is what we are doing. He has replaced about 75% of them. He will be out next week week to complete the project. We only purchased solid doors for entry into a room and hollow for closet doors. We started this process literally days pre pandemic. We were waiting on additional doors as the manufacturer had shut down for a few months (all doors are custom fit).

Thanks for this feedback!

i redesigned my new house last month, when i moved my new house it was looking really old and ancient house, the siding was made of wood and it was really rusty and broken, i also wanted to do some repairing inside like panting, flooring, etc. changing the old doors was also in my plan, and actually i was new here and i didn't know any near company for home repairing so i searched online and guys on www.costshed.com after i send them pics of the doors they advised me to replace 80% of them.
