Why prep matters before floor sanding Floor sanding is one of those jobs that goes much more smoothly when the house is properly prepared. A good floor sander can only work efficiently if the room is clear, the floor is ready, and access is easy. If you leave sorting, moving furniture, or fixing obvious issues until the day the tradesperson arrives, you may pay for extra labour time or need to reschedule.
In New Zealand, where many homes have older timber floors, weatherboard construction, and variable indoor humidity, preparation also helps protect the final finish. A clean, dry, uncluttered work area lets the sander get straight into the job and helps the coating cure properly after sanding.
Confirm exactly what the quote includes Before you start moving furniture, make sure you know what the floor sanding quote covers. Not every floor sander includes the same scope, and a cheap quote can become expensive if it excludes preparation or finishing.
Ask for a written quote that clearly states:
- whether moving furniture is included - whether carpet removal is included - whether nail-pulling, stapled underlay removal, or minor floor repairs are included - how many sanding passes are included - whether staining, sealing, and coating are part of the price - what happens if hidden damage is found once work begins - whether GST is included
It is sensible to get at least two or three written quotes. In many parts of NZ, especially during the drier months when sanding and coating conditions are better, good tradespeople can be booked out in advance.
Clear the room completely The single biggest way to save time is to empty the work area before the floor sander arrives. Sanding crews generally need clear access to every part of the floor, including edges and corners.
Remove:
- all furniture, including couches, beds, tables, chairs, rugs, and storage units - wall hangings, mirrors, clocks, and framed artwork if vibration could affect them - curtains or drapes that hang close to the floor - loose items from skirting boards, window sills, and shelves near the work area - pet beds, toys, and indoor plants
If the job includes multiple rooms, ask the sander whether they prefer rooms cleared one at a time or all at once. Some homeowners find it easier to move furniture into one garage bay or onto a covered deck, but only do this if the area is dry and secure.
Arrange storage before the job starts If you do not have spare space inside, plan where the furniture and contents will go. This is especially important in smaller Kiwi homes, apartments, and townhouses where there may not be a lot of room to shuffle things around.
Good temporary storage options include:
- a garage or carport, if it is dry and secure - one room that will be sanded later in the programme - a neighbour’s spare space, if offered - a short-term storage unit if the job is large or you are renovating several rooms
Avoid stacking furniture directly on damp concrete or leaving valuables in places that are easy to access from outside. If you are using the garage, remember that many garages in NZ are not fully sealed against dust or moisture, so cover items properly and keep them off the floor where possible.
Check for moisture, leaks, and damage Floor sanding is not the right time to discover a hidden leak. Timber floors must be dry and sound enough to sand and finish properly.
Before the work begins, check for:
- leaking taps, pipes, or appliances near the area - signs of moisture around bathrooms, kitchens, laundries, and exterior walls - loose, squeaky, or springy boards - protruding nails or screws - water damage, stains, mould, or cupping in the boards
If you suspect a leak, get it fixed first. A floor sander can usually handle minor cosmetic issues, but active moisture problems should be dealt with before sanding starts. In older homes, especially villas and bungalows, floorboards may also have been patched over the years; let the tradesperson know about any known problem spots in advance.
Protect the rest of the house from dust Even with dust extraction, sanding creates fine dust. A bit of preparation can reduce how far it travels and make cleanup easier.
Take these steps:
- close doors to unaffected rooms - seal gaps under doors with towels or draft stoppers where practical - cover items that remain in the house with clean sheets or plastic - turn off heat pumps or ventilation systems in the work area unless the sander advises otherwise - remove or cover sensitive electronics
If your home has a central heating system or a heat pump return nearby, check with the floor sander about the best way to manage airflow. In some homes, dust can travel through vents if they are left open during the job.
Remove skirting-board hazards and make access easy A floor sander needs good access around the edges of each room. Tripping hazards or clutter can slow them down and create avoidable risk.
Beforehand, tidy the route to and from the work area:
- clear hallways, stairs, and doorways - move boots, shoes, baskets, and bins out of the way - make sure the path from the entry point is wide enough for sanding machines and tools - unlock gates, side doors, or garage access if that is the agreed entry point
If the sander will need to park on the street or in a driveway, let them know about parking restrictions, narrow access, or steep driveways. This matters in many NZ suburbs where street parking can be limited.
Decide what can stay and what must go Some built-in items may not need to be removed, but they should be discussed before the job starts.
Ask the floor sander about:
- built-in wardrobes or shelving that meets the floor - kitchen kickboards or island units - fixed benches and cabinetry - fireplaces, hearths, and hearth surrounds - door stops and threshold strips
Never assume the sander will remove or work around fixed items without checking first. If something is permanently attached or could be damaged by vibration, it may need to be protected, detached, or sanded around carefully.
Check electrical and safety items before work begins Floor sanding itself is not electrical work in the regulated sense, but the job often relies on power tools and may require moving leads, checking outlets, and temporarily isolating nearby appliances.
Before the tradesperson arrives:
- test that power points in the work area are accessible - unplug lamps, chargers, appliances, and electronics - check that extension leads, if needed, will not create a trip hazard - tell the sander about any known electrical faults
If the job requires moving or disconnecting fixed electrical fittings, that should be done by a suitably authorised person. In New Zealand, electrical work is regulated, so do not expect the floor sander to alter wiring or fixtures unless they are licensed to do so. If in doubt, use a registered electrician.
Understand whether consent or other approvals are needed Most floor sanding jobs do not require a building consent. However, if the work is part of a larger renovation, you may need council approval for other building work, especially if you are changing structural elements, adding new flooring systems, or altering fire or access requirements.
It is worth checking with your local council if the job is bundled into a broader renovation. For example, if lifting floors exposes damaged subflooring that needs replacement, or if you are also changing walls, stairs, or wet-area layouts, consent rules may come into play for the wider project.
If you are unsure, ask the tradesperson and check with the council before the work starts. A reputable contractor should be comfortable explaining what is and is not included in the sanding job.
Time the job around weather and drying conditions In New Zealand, weather and humidity can affect sanding and especially coating dry times. Summer is not always ideal if the house is hot and dusty, while winter can slow curing in colder, damper homes.
Plan ahead for:
- dry weather for moving furniture in and out - a stable indoor temperature for coatings - enough time to keep the rooms clear while finishes cure - ventilation that does not blow dust onto wet coatings
If you are in a humid area, near the coast, or in a home that gets cold overnight, ask the sander how long the floor should stay unused after sealing or coating. This can range from light foot traffic after several hours to several days before furniture is returned, depending on the product used.
Prepare family members and pets A floor sanding job can be disruptive, noisy, and dusty. It helps to plan for the household, not just the floor.
Before the job starts:
- arrange somewhere for pets to stay, ideally off-site - organise care for young children if there will be active sanding during the day - let household members know which rooms are out of bounds - plan meals and access so people do not keep walking through the work area
Pets are especially likely to become stressed by the noise and by restricted access. Many homeowners find it easier to have them elsewhere until the floor is fully cured and the dust has settled.
Mark problem areas for the floor sander Before the tradesperson arrives, walk through the rooms and mark anything they should know about.
Useful things to point out include:
- squeaky boards - stained patches - old repairs or filler - lifted nails or tacks - damaged edges near doorways - areas where the boards are particularly thin - previous coatings or paint that may affect sanding
You can mark these with painter’s tape or a simple note. This helps the sander plan the job and may avoid surprises that add labour time.
Compare quotes on more than just price The cheapest quote is not always the best value. A low price may mean less preparation, fewer sanding passes, a rushed finish, or extra charges later.
When comparing floor sander quotes, look at:
| What to compare | Why it matters | |---|---| | Written scope of work | Avoids arguments about what was included | | Preparation requirements | Helps you know what you must do beforehand | | Dust extraction | Reduces cleanup and disruption | | Coating products | Affects durability, appearance, and drying time | | Timing and access requirements | Helps you plan around family and work | | References, reviews, and insurance | Gives confidence the tradesperson is reliable |
Always ask for proof of public liability insurance and check recent reviews or references if you have not used the person before. If they are replacing or repairing flooring as part of the job, make sure they have relevant experience with your floor type.
Final checklist for the day before Use this quick checklist to make sure the job can start on time:
- rooms fully cleared of furniture and loose items - valuables and breakables removed - pets arranged elsewhere - access doors and gates unlocked - parking confirmed - power points accessible - known damage or problem areas marked - leaks or moisture issues checked - skirting, vents, and nearby items protected - quote and scope confirmed in writing
A well-prepared home helps the floor sander spend their time sanding rather than shifting furniture, hunting for access, or dealing with avoidable issues. That usually means a smoother job, less disruption, and better value for your money.
