How much does floor sanding cost?
Sanding can give a worn wooden floor a new lease of life, but the first question is usually the cost. The price depends on your floor and the work it needs, rather than one rate per square metre for every job. This guide explains what affects the cost and why it varies from home to home. We provide a fixed price for floor sanding before we start.
What determines the price of floor sanding?
We assess a few key factors when pricing a floor. Together, they determine the figure in your quote.
| Factor | Why it matters |
|---|---|
| Area in square metres | Larger areas take more time, but large, open rooms often cost less per m² than several small rooms with furniture and awkward corners. |
| Floor type | Solid floorboards, parquet and engineered wood need different approaches. A thin wear layer requires more care and can take longer. |
| Sanding passes and grit stages | A heavily worn floor needs more sanding stages than one that only needs a light refresh. More stages mean more work. |
| Finishing treatment | Lacquer, oil and lye treatments differ in labour and material costs. Oil and lye treatments often involve more coats and longer drying times. |
| Condition and repair | Cracks, holes, old stains, and deep scratches must be filled and repaired before we sand. This takes extra time. |
| Access and furniture | If we need to move heavy furniture, cover items, or work in an occupied home, it takes time. An empty room is faster. |
Two floors of the same size can cost different amounts to sand, depending on their condition, construction and chosen finish. We assess those factors before giving you a fixed price for your floor.
The process: what your quote covers
Proper floor sanding is more than just running a machine over the floor once. It happens in several stages, and you pay for the work involved in those stages.
Sanding in several grit stages
The floor is usually sanded in two to three stages with progressively finer paper. Coarse sanding removes the worn surface layer and levels the floor. Fine sanding then leaves it smooth and ready for treatment.
| Stage | Grit (coarse to fine) | Purpose |
|---|---|---|
| Coarse sanding | Grit 16-24 | Removes old lacquer, oil and the worn surface layer, and levels the floor |
| Medium sanding | Grit 40-60 | Removes traces from coarse sanding and evens out the surface |
| Fine sanding | Grit 80-120 | Leaves a smooth, even surface ready for lacquer, oil or lye treatment |
A floor in good condition that just needs refreshing can be done with fewer stages. A floor with deep scratches, old stains, or unevenness needs to go through all stages. This is one of the biggest differences in price from floor to floor.
Repairs: filling gaps and holes
Before applying the finish, we fill cracks, gaps and holes to create an even surface. We usually mix sanding dust from your floor with a binder so the repair matches the wood's colour. More damage means more time spent on this stage.
Finishing with lacquer, oil or lye
Finally, the floor is treated. This choice affects both the price and how much maintenance you will need to do in the future.
| Treatment | Appearance and durability | Maintenance |
|---|---|---|
| Lacquer | Hard, durable surface. Typically lasts many years with normal use. | Little routine maintenance. Refinishing involves sanding and lacquering the floor. |
| Oil | A natural, matt appearance. Penetrates the wood rather than forming a surface coating. | Worn areas, such as walkways and around the dining table, can be treated locally without sanding the whole floor. |
| Lye | Light, Nordic appearance. Always requires post-treatment with soap or oil. | Needs regular care to stay looking good. |
Oil can be refreshed locally in the most used areas without treating the whole floor. Follow the care instructions for your finish, or contact us to discuss ongoing floor maintenance.
Why floorboards and parquet need different approaches
Floor construction can affect the price more than many people expect. The key factor is the thickness of the wear layer: how much wood can safely be sanded away.
- Solid wooden floorboards usually have the thickest wear layer and can be sanded many times over their lifespan.
- Parquet and engineered wood floors can have thinner wear layers, allowing fewer rounds of sanding and requiring extra care.
- Mosaic parquet often falls between the two and can usually be sanded more times than engineered wood flooring.
A thin wear layer does not make sanding cheaper. It requires more care to avoid sanding too deeply and damaging the floor, so we always check the construction before quoting.
Sand the floor yourself or hire a professional?
You can hire a floor sander and tackle the work yourself. An experienced DIYer may get good results on robust floorboards in good condition, but some common mistakes can increase the cost.
- Risk of sanding too deeply. Leaving the machine still or applying too much pressure can create hollows and drum marks. If the wear layer is thin, the damage may be impossible to repair.
- Edges along the walls. The main machine cannot reach right up to the walls, so an edging sander is needed. The two sanded areas must blend smoothly to avoid a visible border around the room.
- Equipment hire, sandpaper and time. Machine hire, different grades of sandpaper and the finishing treatment all cost money. A single room can take a whole weekend.
A common beginner's mistake is staying in one spot too long and creating hollows that only become obvious once the finish is applied. A professional uses suitable equipment, the correct grit sequence and a finish matched to your floor. This is often worthwhile for a lasting result.

Does floor sanding qualify for tax relief?
Floor sanding is not included in the Danish Tax Agency's lists of eligible household services or green home improvements for 2026. Do not include a tax deduction when budgeting for this work. You can check the current eligible services and conditions with the Danish Tax Agency.
We also work outdoors. If your patio or paving needs attention, we can help with algae treatment for paving and patios and exterior cleaning.
Get a fixed price for your floor within 24 hours
Because the price depends on so many things, the best way to get a realistic figure is to let us see the floor or tell us about it. We will then calculate the number of square meters, floor type, condition, and the treatment you desire, and give you a fixed price without surprises. You will receive a response within 24 hours, and the price we agree upon is what you pay. With a construction guarantee and strong Aarhus references like Isbjerget behind us, you know that the work will be done properly.

Frequently asked questions
What does floor sanding cost per m²?
There is no single rate per m² for every floor. The price depends on the area, construction, condition, sanding stages and chosen finish. We give you a fixed price for your particular floor.
What determines the price of floor sanding?
The main factors are the area in square metres, floor construction, sanding stages, finishing treatment, condition and access. Together, they determine the price of the job.
Can I claim a home improvement deduction for floor sanding in 2026?
Floor sanding is not listed as an eligible service in the Danish Tax Agency's 2026 household services or green home improvement guidance. Do not budget for a deduction on this work. Check the official guidance if your project also includes a different type of work that may qualify.
How many times can a floor be sanded?
It depends on the wear layer. Solid wooden floorboards can usually be sanded many times. Parquet and engineered floors may have thinner wear layers and tolerate fewer rounds of sanding. Careful work avoids using up that layer too quickly.
Can I sand the floor myself?
Yes, but sanding too deeply can leave hollows and drum marks that are difficult to correct. Edges need separate attention, and equipment hire and sandpaper add to the cost. Professional sanding is often the more economical option for a lasting result.
We work throughout Denmark, with most of our floor projects in East Jutland and the Copenhagen area. Read more about floor sanding in Aarhus or floor sanding in Copenhagen, and get a fixed price for your task.
