Parking proximity changes the pace
A van parked outside the door keeps a small move efficient. In Burslem, that is not always possible because of busy kerbside competition near the centre and local shopping parades, so repeated extra walking can become the real cost driver.
Access detail protects the quote
Accurate notes about stairs, shared entrances and carry distance matter more than broad estimates. In Burslem, the job normally runs best when the driver knows the true route from room to van before arrival.
