Pricing

What a floor costs, and why

We do not publish a rate per square metre, because the two floors either side of that number are rarely the same job. What we can do is tell you exactly what moves the figure.

Every quote is written after the slab has been seen, either on site or from photographs and drawings.

A price given before that is a guess, and the correction always arrives later, after you have already planned around it. Eight things move the number.

Area and access

Square metres set the base, but access changes the figure as much as size does. A ground floor slab with a door wide enough to walk plant through is a different job from a first floor apartment reached by a lift, and a small room costs more per metre than a large one because setup is the same either way.

Depth of cut

A deeper cut is more machine time, more diamond wear and more passes. Going from a natural polish to a heavy exposure is a real difference in the cost of the work, not a preference selected from a list.

Slab condition

This is the variable that moves a quote the most. Glue, paint, curing compound, tile beds, patching and an uneven pour all add work before the finish is even started. It is why we would rather look at the slab than quote from a floor plan.

New pour or existing slab

A new slab ground in its window is the straightforward case. An existing floor carries whatever the last thirty years put on it, and the difference between the two is often larger than the difference between two finishes.

Polish level

Sheen is grit, and grit is passes. Stopping at 200 for a matte garage is quicker than taking a floor to 3000 for a mirror. The step up is incremental rather than dramatic, but it is real.

Sealer

The sealer is selected for the exposure rather than by price, and eco based and solvent based systems differ in both cost and cure time. Exterior and coastal surfaces need more from the sealer than an interior floor.

Location

Tauranga and the western Bay is our home ground. Waikato and Auckland work carries travel, and it is quoted transparently as travel rather than folded quietly into a rate.

Programme

Working around other trades, staging a floor in sections to keep a building operating, or working outside normal hours all add time. Where a programme allows us to grind once, in sequence, that is the cheapest way to get the floor.

No rate quoted before the slab is seen, and none corrected afterwards.

Indicative ranges

Ranges are being confirmed and will be published here. In the meantime, tell us the area and send a photograph of the slab and we will give you a real figure rather than a bracket.

Residential
Indicative range to be confirmed. Quoted after the slab is seen.
Garage
Indicative range to be confirmed. Quoted after the slab is seen.
Commercial
Quoted per project against the drawings and the programme.
Exterior
Indicative range to be confirmed. Quoted after the surface is assessed.

How to get a real number quickly

Send the approximate area, the town, whether the slab is poured yet, and a photograph taken standing in the room looking down. That is enough for us to tell you the range and what would push it either way.

For anything specified, send the drawings and the pour dates and we will quote against the programme rather than against a square metre figure.

A sample tile costs you nothing and settles the finish before the quote.
