Each contractor and home builder has their own preferences as to when we should start the floors. We will work with you to accommodate whenever you want us to start. We can come in anytime to do the floors. Having said that, we prefer to score the concrete before the house is framed unless we are scoring a border according to the walls. We normally stain after it is framed (we can also wait for the sheetrock and mud to be completed before starting). We cover the stained floor with paper to protect it until we seal. The floor is sealed after the walls have been painted and near the end of construction.
