Does a Wellington business cover the Hutt and Kapiti?
Many do, but the further ends of the region carry travel time and it shows in the quote. NovaPay asks businesses covering your end first — the Kapiti Coast in particular is served by its own trades rather than by the city.
Why do Wellington quotes ask about access and steps?
Because they are most of the labour. Carrying materials up sixty steps or working off a boundary with no parking is genuinely a different job to the same work on a flat Hamilton section, and a quote that ignores it is the one that gets revised on the day.
Is waterproofing included?
It should be for a shower or wet area, and it is the single most common difference between two bathroom quotes. In New Zealand it must meet the building code, so ask who is doing it and what certification you get.
Can new tiles go over old ones?
Sometimes on a floor if the existing tiles are sound and the height increase works, but rarely in a wet area where the waterproofing underneath is the point. A tiler will tell you after seeing it.
Who supplies the tiles?
Usually you, and it is worth confirming. Order around ten percent extra for cuts and breakages, because matching a batch later is often impossible.
How long will the bathroom be out of use?
Commonly several days once waterproofing cure times and grouting are counted, and longer as part of a full renovation. Ask for the days it is unusable, not just the days someone is on site.
