How do you handle a NON agreed upon price bump?

[Joe S.]

How do you handle price increase by your contractor that was not agreed to by both parties? If you have been rehabbing Houses then you realize that it is common practice for the contractor to try to do an add-on price hike on the final bill. So the scenario plays out like this when you get your final bill there is an add-on fee which was not agreed-upon or discussed. Now there are a few situations where a price increase could be justified, But open dialogue should be included in such a situation as well IMO.

P.S  My title should  read… How do you handle a non-agreed-upon Price bump. I cannot personally edit the title.😁 [Title corrected for you by Moderator Team]
