4.0Why SNZ

Not sure which service you need?

Send us the drawings and tell us the situation. We will tell you which service fits, and if a cheaper one will do the job we will say so.

4.01

Hydraulics only, no distractions.

SNZ estimates plumbing and drainage exclusively. Not electrical, not structure, not fitout. Every hour of our week is spent on hydraulic scope.

4.02

Measured from your actual drawings.

Every estimate is produced using PlanSwift digital takeoff from your specific drawings. No industry averages, no templated assumptions.

4.03

Independent review on every estimate.

Before any estimate leaves our office it is reviewed by a second estimator. On a hospital or a high-rise, that check is not optional.

Send us your drawings.

Tell us the sector, the state and your deadline. Most estimates are back within 72 hours, and we confirm the timeline upfront on large scopes.
