The answer to this question might depend on the quality of the work you have seen in the contractor’s previous work. Most reliable contractors know which sub-contractors and work teams do the best work for the money. They will try to match the job with the capabilities and experience of the sub-contractor and the team, as well as their experience in working with them. If you are planning to hire a sub-contractor whose judgment about sub-contractors and workers you do not trust, it might be a good time to re-think your decision about the contractor.
