DO get a good night’s sleep.
DO have young children with a sitter or occupied in some way so you can focus on the project without interruptions. Remember, time is money.
DO have dogs secured. I love dogs but I am a stranger in their home and they may not like me invading their space.
DO have containers ready, if this was previously discussed.
DON’T clean. You may want to pick up items that could be tripping hazard, but otherwise leave your space as-is.
DON’T allow constant interruptions. This includes cell phones, spouses and kids. Plan ahead and inform them that you need to stay focused on the job.
