While its always best to move out during a remodel, its not always entirely necessary. On smaller renovations or if your home is big enough that the team can work in an isolated part of the house, moving out may not be entirely necessary. However on larger extensive projects and remodels where we are limited on space this may be the best approach and safest move for your health due to dust family if you have small children who may want to run into the job site area. and pets due to high noise levels and heavy foot traffic.
