Hiring a floor sander in NZ is one of those jobs where the cheapest quote is not always the best value. A good contractor can transform tired timber floors with minimal fuss, while a poor one can leave you with gouges, dust, or a finish that wears out too quickly.
Before you commit, it pays to ask a few targeted questions. The right answers will tell you whether the floor sander understands your timber, your finish options, and the realities of working in NZ homes, where old native floors, coastal moisture, and mixed renovations are all common.
1) What experience do you have with my type of floor?
Not all timber floors are the same. Native timber such as rimu, mataī, tōtara, and kauri can behave differently from pine, engineered boards, or parquet. If the sander has only worked on one type of floor, that is worth noting.
Good answers sound like:
• They ask what timber you have before quoting.
• They explain how much can be sanded off safely.
• They mention any risks with old floors, nail heads, gaps, or previous coatings.
• They can describe similar jobs they have done in NZ homes, especially older villas, bungalows, or coastal properties.
A careful floor sander should also be upfront if your floor may be too thin for aggressive sanding, or if repairs are needed first.
2) How will you prepare the floor before sanding?
Preparation makes a big difference to the final result. A proper contractor should not just turn up with a machine and start sanding immediately.
Ask what they will do before work begins, and whether preparation is included in the quote.
Good answers sound like:
• They will inspect for loose boards, protruding nails, squeaks, stains, or old adhesives.
• They will move agreed furniture only if arranged in advance.
• They will remove or protect skirting, doors, and adjoining surfaces as needed.
• They will confirm whether you need to clear the room completely before they arrive.
If you are comparing quotes, check whether prep, minor repairs, and cleanup are included. In NZ, it is common for quotes to vary because one contractor includes more than another.
3) What sanding system and dust control do you use?
Dust is one of the biggest concerns for homeowners. Modern floor sanding equipment can greatly reduce it, but “dust reduced” does not mean “dust free”.
Ask what machine system they use and how they manage containment in occupied homes.
Good answers sound like:
• They use a modern extraction system with effective dust capture.
• They explain that some fine dust is still normal and advise how to protect other rooms.
• They seal off adjacent areas where practical and discuss ventilation.
• They tell you what cleanup is included at the end of the job.
A sensible contractor will be honest about the limits of dust control, especially in older homes with open layouts, multiple rooms, or weather-sensitive access points.
4) What finish do you recommend, and why?
The right finish depends on the room, the amount of traffic, and your lifestyle. A family hallway, a rental property, and a sunny kitchen all have different needs. Good sanders should explain the options rather than push one product for every floor.
Common finish questions to ask:
• Is the finish water-based or oil-based?
• How many coats are included?
• How long before we can walk on it?
• How long before furniture can go back?
Good answers sound like:
• They explain the look and durability of each option.
• They give realistic drying times, not just the fastest possible.
• They recommend a finish based on NZ conditions, such as humidity, sunlight, and household traffic.
• They tell you how the finish will affect colour, sheen, and future maintenance.
As a general guide, finishing costs are often included in a floor sanding package, but extra coats or premium products can increase the price. Indicative NZ price ranges are often:
• Floor sanding only: $35–$60 per square metre
• Sanding plus standard finish: $55–$90 per square metre
• Repairs, staining, or premium finishes: $90–$140+ per square metre
These are only broad guides. Larger jobs, difficult access, or heavy repair work can shift the price significantly.
5) What is included in the quote, and what costs extra?
A vague quote is a warning sign. You want to know exactly what is included so there are no surprises once the job starts.
Ask for the quote in writing and check the details carefully.
Good answers sound like:
• The quote lists sanding, edging, finishing coats, and basic cleanup separately or as a package.
• They identify any exclusions, such as furniture moving, repairs, staining, or extra coats.
• They explain whether GST is included.
• They note whether the quote is fixed or subject to change if hidden damage is found.
In NZ, it is also smart to ask about travel charges if you are outside a main centre. Rural or regional jobs can carry extra transport or accommodation costs, especially if the floor sander is coming from Auckland, Wellington, Christchurch, or another hub.
6) How long will the job take, and what should I expect during the process?
Floor sanding can take longer than people expect, especially if repairs or multiple coats are needed. The contractor should be able to give you a practical timeline for each stage.
Good answers sound like:
• They give a clear estimate for sanding, coating, and drying time.
• They explain when you can safely walk on the floor, and when furniture can return.
• They warn you about temperature and humidity affecting drying times.
• They tell you how to prepare your household for noise, odour, and limited room use.
For many homes, the process takes around 2–5 days depending on floor size, condition, and finish type. Oil-based systems often need longer drying time than water-based finishes.
7) Do you have references, photos, or proof of previous work?
Any experienced floor sander should be able to show evidence of recent work. This does not need to be a big sales pitch, just enough to confirm they consistently deliver a good result.
Good answers sound like:
• They can show before-and-after photos of similar NZ jobs.
• They have recent customer feedback.
• They are happy to explain how they handled problem floors.
• They can talk you through what they would do differently for your home.
If a contractor avoids this question, that is a useful warning sign. You are hiring someone to work on a major visible surface in your home, so proof of workmanship matters.
8) What should I do to look after the floor after sanding?
A good floor sander does not disappear once the last coat is dry. They should give aftercare instructions so the floor lasts as long as possible.
Good answers sound like:
• They explain what cleaning products are safe for your finish.
• They tell you when to use felt pads and how to protect high-traffic areas.
• They advise on rugs, pet claws, and furniture movement.
• They recommend when a recoat may be needed in future.
In NZ homes, sunlight and humidity can affect timber over time. Good aftercare advice should reflect that, especially in homes with strong UV exposure, coastal air, or damp winters.
Quick checklist before you book
Use this as a simple final check before accepting a quote.
• Have they inspected the floor properly?
• Do they know the timber type and condition?
• Is the dust control approach clear?
• Is the finish recommendation explained in plain language?
• Does the quote list inclusions and exclusions?
• Are drying times and access restrictions realistic?
• Can they show recent examples of similar work?
• Do they provide aftercare advice?
If you get clear, practical answers to these questions, you are much more likely to end up with a floor you are happy to live with. The best floor sanders in NZ do not just sand timber well — they communicate clearly, set realistic expectations, and help you avoid costly mistakes.
