Floor sanding in an apartment: what to plan
Sanding floors in a flat involves the floor itself, neighbours, building rules, dust and access for heavy machinery. This guide explains what to check in an owner-occupied, co-operative or rented home, how we control dust, whether you can stay during the work and how the quotation is prepared.

Do you need permission for floor sanding in an apartment?
The first question in an apartment building is rarely technical, but legal: are you even allowed to start? The answer depends on your type of housing, and the sanding itself is usually the least of the problems. You need to sort out the rules regarding noise, working hours, and alterations first.
- Owner-occupied apartment: you own your home, but the owners' association may have rules in the bylaws and house rules about noisy work, working hours, and floor coverings. Floor sanding in an owner-occupied apartment rarely requires formal permission, but it's wise to read the house rules and notify the board if the work is extensive.
- Co-operative housing: in a co-operative association, major alterations to the home may require approval. The sanding itself is usually considered maintenance, but check the association's bylaws to be on the safe side before booking a date.
- Rented housing: if you do not own the floor, you must have your landlord's consent before altering it. Get it in writing to agree on both the scope and who pays.
We never claim to know the specific rules of your association or municipality. But we always recommend that you clarify it with the association or landlord before we set a date in the calendar.
Neighbour considerations: noise, time, and notification
Sanding machines generate noise that travels through floors and walls. Check the building's rules for noisy work and agreed working hours, which are often restricted to weekday daytime. We plan the work around the rules that apply to your property.
A small notice in the stairwell a few days before, informing neighbours that the floor will be sanded and how long it will take, makes a big difference. People are much more patient when they know the noise is temporary and has an end date. We work efficiently and consolidate the noisy steps so they don't drag on unnecessarily.
How we handle dust in an apartment
Dust is what people fear most about sanding floors indoors, and for good reason: in an apartment, fine wood dust can otherwise penetrate everything from kitchen cabinets to wardrobes. We therefore sand with sanders with dust extraction that collect most of the dust directly at the source, so it doesn't swirl around the room.
Before we start, we cover doorways with plastic and cover furniture that cannot be moved out. In this way, we keep the dust in the room being worked on, and the rest of the apartment remains clear. There will always be a small amount of fine sanding dust left, but far less than most people expect, and we clean up after ourselves.
Can you live in the apartment while the floor is being sanded?
The short answer is: often yes, but it depends on the size of the apartment and how many rooms are sanded at a time. In a larger apartment, we can do one room at a time, so you have another place to stay. In a smaller one-room or two-room apartment, it can be difficult to avoid dust and smell throughout the home simultaneously.
The finishing product also matters. Odour, ventilation requirements and drying times vary between lacquers, oils and the finish used after lye treatment. For a large area, staying elsewhere may be more convenient while the finish dries. The table gives general planning examples; the product instructions take precedence.
| Treatment | Smell and fumes | Can you stay? | Drying time before careful use |
|---|---|---|---|
| Varnish | Product-dependent fumes; follow ventilation instructions | Depends on the treated area, access and product instructions | Approx. 24 hours, full curing 5 to 7 days |
| Oil | Depends on the lye product and subsequent finish | Depends on the area and finishing instructions | 12 to 24 hours per layer |
| Lye | Depends on the lye product and subsequent finish | Depends on the area and finishing instructions | Soap treatment after approx. 24 hours |
Access: stairs, elevator, and heavy machinery
A professional floor sanding machine is heavy, and this is a logistical detail that is often overlooked in an apartment building. We need to be able to carry the machines up to your floor, and it makes a difference whether there is an elevator or if the machines have to go up a narrow staircase. It's rarely a showstopper, but it's good to know in advance so we can plan the transport correctly.
Please tell us when you contact us what floor you live on, if there is an elevator, and what the access conditions are. Narrow stairwells, low ceiling heights, and parking close to the entrance are all things we take into account so that the day itself runs smoothly.
What does floor sanding cost in an apartment?
The price of sanding a floor depends on several things, and therefore we always give a fixed price after we have seen the floor. The typical factors that affect what floor sanding costs per m2 in an apartment are:
| Factor | Impact on price per m2 |
|---|---|
| Number of square metres | Larger areas often result in a lower price per m2 |
| Floor condition | Deep scratches, holes, and many layers of old varnish take longer |
| Number of rooms and edges | Many small rooms and corners require more edge sanding |
| Choice of treatment | Standard oil and lacquer share the same base price; drying schedules differ |
| Access to the floor | Stairs without an elevator can increase working time |
The final quotation for floor sanding and lacquering depends on the agreed work and the condition of the floor. Standard sanding and a standard finish cost 175 kr per m2 including VAT for areas of 36 m2 or more. Smaller jobs have fixed area-based prices. Floor sanding is not listed as eligible for Denmark's 2026 household services or green home improvement deductions, so compare quotations without assuming a tax saving.
Can you sand the floor in the apartment yourself?
Many consider sanding the floor themselves to save money, and that's understandable. But in an apartment, there are some extra pitfalls. You can rent a sanding machine from a hardware store, but a large belt sander is difficult to control, and if you lose concentration for a moment, it can quickly sand deep grooves or waves in the floor, which are expensive to correct.
An orbital sander, which many people own, is too weak to sand an entire floor down to bare wood. It can freshen up a surface, but it does not effectively remove old varnish or deep damage. If you sand the floor yourself with an orbital sander, you usually end up with a half-hearted result and a lot of dust. In an apartment building where neighbours are close by, and where a mistake on a rented floor can be expensive, we recommend letting a professional handle it. This ensures an even surface and keeps dust down.
Can parquet flooring be sanded in an apartment?
Yes, most parquet floors can be sanded, and it is one of the most rewarding tasks in an apartment. The crucial factor is the thickness of the wear layer. A solid parquet floor can be sanded many times, while a thin engineered parquet only tolerates one or two sandings in its lifetime. We always assess the wear layer first, so we don't sand too much. You can read more about sanding parquet flooring and when a wooden floor needs sanding.
Once the parquet has been sanded down, it needs to be treated again. In an apartment, many choose floor sanding with varnishing, because varnish is durable and easy to keep clean in a home with daily traffic. Others prefer oil for its natural look. If you are unsure what suits your floor and your everyday life, our guide on varnishing or oiling wooden floors will help you with the choice.
Realistic scope in a smaller apartment
In a smaller apartment, it is important to have a realistic expectation of the process. The actual sanding of a few rooms goes quickly, but you need to factor in drying time, especially with varnishing, where the floor must remain untouched between coats. This means that for a short period you must be able to do without the room or rooms being treated.
Our experience is that floor sanding in an apartment is almost always worth the trouble. A worn floor that has become dark and scratched returns to new, and it elevates the entire home without the expense and mess of tearing up the floor and laying a new one. We plan the process to disturb you and your neighbours as little as possible.

Frequently Asked Questions
What does floor sanding cost per m2?
Standard sanding with a standard finish costs 175 kr per m2 including VAT from 36 m2; smaller jobs start at 3.700 kr. Standard oil and lacquer share the same base rate. Access, floor condition and any additional work are assessed before a fixed quotation is confirmed.
Can you live in the apartment while the floor is being sanded?
Often yes, but it depends on the size of the apartment and how many rooms are sanded at a time. Dust and smell from rough sanding are unpleasant, and varnish requires good ventilation for the first 24 hours. In a smaller apartment, it may be more practical to stay elsewhere while we work.
Can you sand the floor in an apartment yourself?
You can rent a sanding machine, but a large belt sander is difficult to control and can easily create deep marks in the floor. An orbital sander is too weak to sand an entire floor down to bare wood. In an apartment with close neighbours, we recommend letting a professional handle it, so the result is even and dust is kept down.
How long does it take to sand and varnish a floor?
A typical one or two-room apartment usually takes one to three working days to sand and treat. Varnishing requires drying time between coats, and the floor can be used carefully after about 24 hours, but fully cures over 5 to 7 days. We will give you the specific timetable before we start.
How much dust does floor sanding create in an apartment?
We sand with sanders with dust extraction that collect most of the dust directly at the source. We also cover doors and furniture so that dust does not spread to the rest of the apartment. There will always be a small amount of fine dust, but far less than most people expect.
Do you need permission from the owner's association or co-operative for floor sanding?
The sanding itself rarely requires permission, but many owner and co-operative associations have rules in the house rules about noise and working hours that you must follow. If you are renting, you should have your landlord's consent before altering the floor. Always check the association's bylaws or ask the landlord before setting a date.
