Most interior work happens in houses people are still living in. It is entirely workable, and it goes better when everyone knows the sequence in advance.
We work room by room rather than opening up the whole house at once, so you keep the use of most of it throughout. Furniture is moved to the centre and sheeted. Small, fragile, and valuable items are better moved by you before we arrive, not because we are careless, but because you know what matters.
Expect the working rooms to be unusable during application and cure, expect some smell even from low-odour products, and expect us to tidy at the end of each day. If a day's work will block a bathroom or a stairwell, we will say so the day before rather than the morning of.
