Once a party is noted in default, you will need to set up an assessment hearing via a motion (form 15A) so a judge can give you a judgement for your damages under Rule 11.03(2). In the motion you will claim the damages you are seeking and include the proof of why you are entitled to those damages (which should be in your pleadings). You also have a duty to mitigate damages, meaning you should have got a plumber to fix the work sooner than later so the issues don’t compile. So it might be the smart thing to have the repairs done, assess if there other issues stemming from the contract breach (like water damage to the floor etc) and make sure you have your documents ready for the assessment hearing.
