What the figure is built from
Four things. What is going. Where the nearest legal stop is at each end, and how far the carry is from it. The stairs, the lift or the absence of both. And the awkward bit, whatever it turns out to be.
Two of those are things customers rarely think to mention and both are settled before the booking rather than found on the day. A crew sized for a drive and sent to a fourth-floor walk-up will not finish well, however willing everybody is at nine in the morning.
No price, rate card or transit time appears anywhere on this site, because none of them is knowable before we know the awkward bit. Start on the quote form, or read the questions page.
