During a renovation, doors are usually installed among the last things, when the walls are ready and the floor covering is laid. If you need to replace one or two doors, you can also request this without any other renovation.
When doors are installed during a renovation
The height of the door frame is set by the level of the finished floor, so the frame is installed when it is known what covering there will be on both sides of the door and how thick it will be. If the floor is still being levelled or floor screed is being laid, the doors are left for later.
Laminate under a door must not press against the frame. In the Quick-Step instructions the expansion gap is at least 8–10 mm on all edges, including around thresholds and under doors. This is why door work and floor work are planned together.
Whether the opening suits the new doors
An existing opening may not be straight, and its size may not match the size of the doors you chose. Before buying doors, measure the width and height of the opening and the thickness of the wall in several places. If the opening is narrower than needed, it can be widened.
Widening an opening in a non-load-bearing partition is work on the apartment's own property. A new opening, or a reconstruction of an opening, in a load-bearing wall is a simplified reconstruction that needs a structural solution from a certified architect and a construction engineer, an explanatory memorandum and, if the building is divided into apartment properties, the consent of more than half of the apartment owners. More on the page creating a door opening.
Law on Residential Properties, Section 3(2) (doors and non-load-bearing partitions belong to the apartment); Cabinet Regulation No. 529, paragraph 1.¹, sub-paragraph 6 and paragraph 7.², sub-paragraph 8. Checked 11.11.2026.
The order of installation
- Old doors The old leaf and frame are removed and the edges of the opening are cleaned up.
- Assembling the frame The frame is assembled to the size of the door and the level of the finished floor.
- Levelling and fixing The frame is set into the opening, levelled vertically and horizontally and fixed.
- Leaf and hardware The leaf is hung, the handle and lock are fitted and adjusted so that the door closes evenly.
- Trims Trims are fitted on both sides to cover the gap between the frame and the wall.
Installing sliding doors
Sliding doors can run on a track above the opening or slide into the wall. A track door needs a free wall next to the opening where the leaf will stand when open. A pocket door needs a cassette in the partition, which is usually built together with a new plasterboard partition, so it is decided before the wall work.
What to decide before buying doors
- The number of doors and the size of each opening.
- Which way the doors will open and whether there will be a threshold.
- The type of leaf: hinged, sliding or pocket doors that slide into the wall.
- Whether you will buy the doors yourself. In your request, write whether you will choose the materials yourself.
- Whether the floor covering is already laid or is still to come.
Interior door installation price
Interior door installation: from €100 per door. Prices are for labour. Materials are calculated separately in the estimate. The price depends on the type of door (hinged, sliding, pocket), the condition of the opening, the wall thickness and whether old doors have to be removed.

|---|---|---|
| One door for a bathroom | 1 × €100 | from €100 |
| A 3-room apartment with 5 interior doors | 5 × €100 | from €500 |
Doors are often replaced during a cosmetic renovation, where the price is from €100/m² of apartment floor area. All prices are on the page renovation prices.
