Deciding which parts of the work you should do is a matter of skill and time.

It does not make a lot of sense to take on tasks that must be completed at a stated time if you have any doubts about your ability to meet the schedule. Delays are expensive. Especially if the schedule is tight, take on only those tasks you know you can complete as planned — on time and up to quality standards for the rest of the job.

Local building regulations might require that some of the work be completed by a licensed professional. You might, however, be able to do some of the finishing work after the professional completes the more technical parts of the job. You will need to have a conversation with the contractor or subcontractor to make these decisions.

You should also consider how much patience you have and how tight the budget for the project is. Mistakes are costly in some parts of a remodel or a home addition. If you can’t afford a mistake, it is probably better to just let the professionals do the job.

Don’t forget about quality. If you don’t have the skill or the patience to do the work to exacting specifications you could risk sacrificing the quality of the whole job.
