I recommend measuring only those rooms where you or your loved ones spend the most time during the day (sleeping, working places). I find that a bedroom can be mapped within 1 hour.
1 room : $50
2 rooms: $80
3 rooms: $110
4 rooms: $140
This price includes the traveling fee if you live on the Sunshine Coast (between Noosa-Maroochydore) Queensland.
