Why insurance matters when hiring a floor sander
Sanding and refinishing floors is a high-risk job from a homeowner’s point of view. The work is messy, uses machinery, creates dust, and can quickly go wrong if the tradesperson is careless or equipment fails. A mistake can lead to scratches, gouges, burnt timber, damaged skirting boards, stained carpets, smoke, or even a fire risk if sanding dust is not managed properly.
That is why insurance should be part of your hiring decision, not an afterthought. If something goes wrong, the right cover can mean the difference between a straightforward claim and a costly dispute.
In New Zealand, a floor sander is not usually a licensed trade in the same way as electrical work or plumbing. But they should still operate like a professional business: with proper insurance, safe work practices, and written terms.
The main types of insurance a floor sander should carry
Not every contractor carries the same cover, and policy limits vary. But for floor sanding work, these are the key types to look for.
| Insurance type | What it covers | Why it matters to you |
|---|---|---|
| Public liability insurance | Injury to third parties and accidental damage to property | Protects you if the sander damages your home or someone is hurt by their work |
| Contract works insurance | Damage to the job while it is in progress | Useful if floors are damaged during sanding, coating, or drying |
| Tools and equipment insurance | Theft, loss, or damage to their machines and tools | Reduces the chance of delays and helps the contractor keep working |
| Personal accident / income protection | Injury to the contractor | Not directly your protection, but helps keep the business stable if someone is injured |
| Motor vehicle insurance | Vehicles used for work | Relevant if they are transporting equipment or materials to your property |
Public liability insurance
This is the big one for homeowners. Public liability insurance generally covers accidental injury to other people and damage to their property caused by the contractor’s work.
For floor sanding, that can include:
- damage to timber floors from a machine fault or operator error
- sanding through a floorboard or damaging adjacent surfaces
- accidental damage to walls, doors, trims, or cabinetry
- injury to a visitor, tenant, or neighbour caused by work activities
- damage from dust, spills, or moving heavy equipment through the house
A good policy should have a cover limit large enough to matter. Many tradespeople carry at least $1 million or $2 million, but higher limits are common on larger jobs. The right amount depends on the size and value of the property, and whether the work is in a high-value home, apartment, or commercial premises.
Contract works insurance
This protects the work while it is underway. For example, if a sanded floor is damaged by a burst pipe, accidental spill, fire, or some other event before the job is complete, contract works cover may help.
For homeowners, this matters because flooring jobs often involve multiple stages:
- sanding back the existing surface
- repairs or gap filling
- staining, oiling, or coating
- drying and curing time
Damage can happen at any point. If the contractor has contract works cover, there is a better chance the loss can be managed without a fight over who pays.
Tools and equipment insurance
This cover does not protect your home directly, but it can protect the contractor’s business from delays. Floor sanders rely on specialised machines, vacuums, abrasives, and coating equipment. If those are stolen from a ute or damaged on site, the job can stall.
Why should you care? Because a contractor who can replace equipment quickly is less likely to leave you with a half-finished floor for days.
Motor vehicle insurance
Many floor sanders use vans or utes loaded with machinery, abrasives, and finishes. If their vehicle is damaged in transit, it can affect the job schedule. It also matters if the vehicle is parked at your place and causes damage when loading or unloading.
Health and safety cover is not the same as insurance
A professional floor sander should also have strong health and safety systems. That includes:
- dust control and extraction
- safe handling of solvents and coatings
- proper ventilation
- safe storage of flammable products
- clear site management to reduce trip hazards
Health and safety practices are not insurance, but they reduce the chance of a claim ever being needed.
How insurance protects you as the homeowner
Insurance is really about risk transfer. Instead of you personally footing the bill for a mistake, the contractor’s insurer may handle the loss if it falls within policy terms.
That protection can help in several ways:
- Damage to your property: If a machine gouges a floor, scratches a benchtop, or marks painted walls, insurance may cover repair costs.
- Injury claims: If a visitor or tenant is injured because of the contractor’s work area, public liability may respond.
- Project delays: If equipment is stolen or damaged, the contractor may be able to recover and finish the job sooner.
- Dispute reduction: Knowing there is insurance in place can make it easier to resolve issues without lengthy arguments.
That said, insurance is not a substitute for good workmanship. You still want a tradesperson with experience, references, and clear written quotes.
What insurance does not usually cover
It helps to know the limits. A policy does not automatically cover every problem.
Common exclusions can include:
- pre-existing damage to floors or subfloors
- poor workmanship that falls below the policy’s intended scope
- normal wear and tear
- damage caused by defects you knew about and did not disclose
- work done outside the contractor’s insured activities
- fines, penalties, or compliance breaches
Also, if a contractor lets a policy lapse, uses the wrong business structure, or works outside the terms of cover, a claim may be declined. That is why confirming cover matters.
How to confirm a floor sander’s insurance before work starts
Do not just take “yes, I’m insured” at face value. Ask for evidence.
Ask for these details in writing
Request a copy of the contractor’s certificate of currency or insurance schedule showing:
- the insurer’s name
- the policy number
- the type of cover
- the cover limit
- the policy period and expiry date
- the insured entity’s exact name
- whether the cover includes the type of work they will do at your property
If the job is being done by a company, make sure the insured name matches the business name on the quote or contract. If it is a sole trader, the policy should be in their name or trading entity.
Check the cover is current
A policy certificate can look legitimate even if it has expired. Check the expiry date and ask whether the policy has been renewed.
Confirm the work is included
Do not assume every general handyman policy covers floor sanding. Ask directly:
- Does the policy cover timber floor sanding and coating?
- Does it cover both residential and commercial sites?
- Does it cover the use of solvents, stains, oils, or polyurethane?
- Are there exclusions for dust, heat, or flammable products?
Match the insurance to the job size
A small lounge may not need the same risk profile as a whole-house sand and refinish in a large villa, character home, or investment property. If the job is substantial, it is reasonable to ask about higher liability limits.
Keep copies of everything
Save:
- the quote
- the written scope of work
- the insurance certificate
- any emails about coatings, drying times, or furniture moving
If there is a problem later, those records will help.
Other checks NZ homeowners should make
Insurance is only one part of hiring well. Before you sign anything, also check:
- Experience with your floor type: Native timber, hardwood, engineered flooring, and parquet can all require different techniques.
- References or recent photos: Ask for jobs similar to yours, especially if your home is older or has delicate timber.
- Dust control methods: Modern sanding should use strong extraction and careful masking.
- Drying and curing advice: New Zealand weather can affect drying times, especially in damp winter conditions or humid coastal areas.
- Written quote and scope: Make sure it states what is included, such as repairs, stain, coats, moving furniture, and GST.
If the work includes any regulated building activity, ask whether it affects compliance requirements. For example, a floor sander may need to coordinate with other trades if skirting, stairs, moisture issues, structural repairs, or adjoining building work are involved. Electrical, plumbing, gasfitting, and drainlaying work are separately regulated in New Zealand and must be carried out by appropriately licensed people where required.
When consent or other compliance issues might come up
Floor sanding itself usually does not require building consent. But the overall project sometimes can.
For example:
- replacing damaged subflooring or structural timber may trigger building consent requirements
- moving or altering stairs, balustrades, or structural elements can be consent-relevant
- moisture issues or rot may indicate bigger building work is needed before sanding
- if the job is part of a wider renovation, other trades may need to be engaged
If you are unsure, check with your local council or a qualified building professional before work starts. It is far easier to sort out compliance up front than to deal with problems after the finish is down.
A practical checklist before you hire
Use this simple checklist when comparing floor sanding quotes:
- Get at least two or three written quotes.
- Ask what insurance the contractor carries.
- Request a current certificate of currency.
- Confirm the policy includes the type of floor work you need.
- Check the cover limits are appropriate for your home.
- Ask who is responsible for protecting furniture, walls, and other finishes.
- Make sure the quote clearly lists prep, sanding, coating, and cleanup.
- Confirm timeframes, drying times, and when you can move furniture back.
- Keep all documents in one place.
The bottom line
Yes — your floor sander should be insured. At a minimum, look for current public liability cover, and ideally ask whether they also carry contract works and tools cover. Insurance will not guarantee perfect workmanship, but it gives you a vital layer of protection if something goes wrong.
The safest approach is simple: compare written quotes, check the insurance documents, confirm the work is included, and choose a contractor who answers questions clearly and professionally. That extra ten minutes up front can save you a lot of money and stress later.
