Cabin cleaning: complete checklist for opening and closing

Cabin cleaning is two jobs, not one: spring preparation when you open, and closing when you leave the cabin for the winter. The most expensive mistake is skipping frost protection in the autumn – a burst water heater or a frozen pipe section can cost tens of thousands. Below you will find two numbered checklists, one for each end of the season.

The Norwegian cabin rhythm is cyclical. You open in Easter or May, use the cabin throughout the summer, and close again before the cold truly sets in. The two lists are connected: everything you do correctly when closing saves you work and prevents damage when opening.

How do I prepare the cabin in spring?

After a winter with the water shut off and doors closed, dust, perhaps mice, and a stuffy smell will have accumulated. Go through the rooms in this order to avoid cleaning the same surface twice.

1. Ventilate first. Open all windows and doors for half an hour before you begin. Fresh air removes most of the stuffy smell.
2. Check for mice. Look for droppings, gnawed textiles, and nests in cupboards and under beds. If you find traces, discard affected food and textiles, and wash surfaces with soapy water.
3. Dust from top to bottom. Start with ceiling moldings, shelves, and lamps, so the dust lands on the floor you will clean last.
4. Turn on the water carefully. Slowly open the main tap and go around to check for leaks at connections and traps before leaving the room. Flush all taps until the water runs clear.
5. Flush toilet and traps. Flush several times to rinse out the antifreeze you added last autumn.
6. Clean refrigerator and freezer. Wipe out the old absorbent, wash with baking soda and water, and leave the doors open until completely dry before turning on the power.
7. Air out textiles. Hang duvets, pillows, and blankets outside on a sunny day. Sunlight and air remove moisture and odor better than anything else.
8. Clean floors last. Mop or wash all floors, and wipe thresholds and door frames where dust settles.
9. Set up outdoor furniture. Wipe down, check for rot and rust, and oil any wood that has dried out over the winter.

Once you have gone through this, the cabin is ready for use. If you need to go deeper – for example, after a season of heavy use – you can follow a regular deep clean guide for the most worn rooms.

How do I close the cabin for winter?

Closing is mostly about two things: removing everything that can freeze, and preventing moisture and animals from causing damage while the cabin is empty. This is the list you absolutely should not rush through.

1. Close the main tap and disconnect the water supply.
2. Empty all pipes and the hot water heater. Open taps at low points so the water drains out. A liter of forgotten water in a pipe can burst it.
3. Pour antifreeze into all traps – kitchen, bathroom, drains, and toilet. Empty the toilet bowl and fill with antifreeze there too.
4. Completely empty the refrigerator and freezer. Clean them, and leave the doors ajar. Closed, damp cabinets become moldy cabinets.
5. Remove all food. This includes seeds, crispbread, pet food, and spices. What you don't take, the mice will find.
6. Seal possible entry holes with steel wool or sealant. Mice can get through openings less than a centimeter.
7. Place moisture and odor absorbents in the most exposed rooms, and preferably a couple of mousetraps.
8. Lift mattresses off their bases and leave cupboard doors ajar, so air circulates and moisture does not collect.
9. Pack textiles in sealed plastic boxes. Bedding, towels, and clothes in cardboard or open baskets are tempting nesting material.
10. Take out trash and valuables, unplug appliances, and turn off the main power if you don't have a frost guard or alarm that needs electricity.
11. Bring in outdoor furniture or cover it. Draw curtains slightly so sunlight doesn't bleach textiles unevenly.

The simplest rule of thumb: if it contains water, it should be emptied or frost-protected.

What do I do about mold and moisture?

Mold needs two things – moisture and stagnant air – and a closed cabin provides both. Prevention in autumn is far simpler than remediation in spring. If you still get mold spots on walls or in grout, wash with water and a mild detergent, and dry thoroughly afterwards. Stubborn spots on tiles and grout can be treated with a chlorine-based product.

Here is a safety rule worth learning by heart:

Safety with cleaning products: Never mix chlorine bleach with anything other than water. Chlorine bleach and vinegar produce toxic chlorine gas. Chlorine bleach and ammonia produce chloramine. Both are dangerous to inhale. Use gloves, ventilate well, and keep products separate.

If the cabin is in a humid climate near the sea, moisture and salt absorbents are cheap insurance. Check them at each visit and replace when the box is full.

What about limescale, natural stone, and surfaces?

Many cabins have limescale deposits on bathroom surfaces and around taps after a season. Vinegar and citric acid effectively dissolve limescale, but here you must be careful with the underlying surface.

Acid – vinegar, citric acid, and most limescale removers – etches natural stone, marble, granite, and slate, leaving dull spots that won't go away. It can also damage untreated wood and some enameled surfaces. If you have a stone countertop or slate tiles, use a pH-neutral product made for stone instead. Always test in an inconspicuous area first. You can find more in our guide on removing limescale in bathrooms and showers.

What should I bring to the cabin?

Have a dedicated cabin box so you don't have to search every time. The table shows what covers both jobs.

How much does it cost to get help with cabin cleaning?

The prices here are approximate starting points for 2026, not a binding quote. The cost of the assignment depends on size, condition, and accessibility. You will receive the final price in a specific quote from us – and it is often higher than the lowest estimate. Request a quote for a price that actually applies to your cabin.

If you want to outsource the job, the market price for cabin cleaning as of 2026 typically ranges around NOK 600–900 per hour, often with a fixed minimum fee for call-out since cabins are often in remote locations. Many companies offer a fixed seasonal package for opening or closing.

An important caveat: the general minimum wage for cleaning is NOK 236.54 per hour for adults (from June 15, 2025, revised annually). A quote with an hourly rate far below this does not legally cover wages, employer contributions, and equipment – it is a red flag.

Also, check that the company is approved. Since July 1, 2018, it has been illegal, even for private individuals, to purchase cleaning services from a business not listed in the Norwegian Labour Inspection Authority's Renholdsregisteret (Cleaning Register). It is punishable by law. Look up the company before you order – read more in the guide on legal cleaning help and the Cleaning Register.

Summary

Cabin cleaning is an annual two-act routine. In autumn, you frost-protect, empty water and food, and keep out moisture and mice. In spring, you ventilate, turn the water back on, and clean away winter's dust. Keep these two lists in your cabin box, and you will avoid both frost damage and an unpleasant surprise at Easter.
