The walls between apartments and the floor slabs are themselves the building's common property, so the work is done in the apartment's finish, not in them. The price is by estimate, because it depends on the surface, the area and how much room area and height you are ready to give up.
Where the noise comes from and what can be done in the apartment
Poor soundproofing is mentioned among the typical problems of the 602 series, the 316/318 series and the “Khrushchyovka” (apollo.lv, cityreal.lv). In other buildings too, how much you hear the neighbours depends on the particular wall, floor slab and pipe recesses.
Voices and the television usually come through the wall or ceiling, while footsteps and falling objects come through the floor slab. This determines which surface to treat: the wall between apartments, the ceiling or the floor. In the request, describe what disturbs you and in which room.
What belongs to the apartment and what to the whole building
The Law on Residential Properties counts the finish of ceilings, floors and walls and non-load-bearing internal partitions as part of the apartment. Common property includes load-bearing walls, walls between apartments and floor slabs with their thermal and sound insulation.
In your own apartment an owner may work without anyone else's approval as long as the work does not affect common property or other apartments. If it affects common property, the consent of the apartment owners' association is needed, and if it affects a neighbour's apartment, that owner's consent as well. If you are unsure which side your plan falls on, ask the building manager before the work.

Wall soundproofing
Next to a wall between apartments, a plasterboard lining on a metal frame is usually built, with insulation material between the profiles. In Knauf dry construction systems the frame is made of CW profiles (studs) and UW profiles, which are fixed to the floor and ceiling.
How much the noise will drop depends on the construction and on whether sound also arrives by other routes, for example through the floor slab or a pipe recess. A result in decibels cannot be promised in advance. For more on plasterboard work, see plasterboard partition walls.
Ceiling soundproofing
For the ceiling, a suspended plasterboard ceiling with insulation above it is built. The room becomes lower, and the light points must be moved to the new ceiling, so they are planned together. More: plasterboard ceilings.
Floor soundproofing
On the floor side, you work with layers above the floor slab: the base, screed or floor covering. The floor slab itself is common property, so it is not touched. A new floor layer raises the floor level, and this must be matched with door thresholds and other rooms.
If you are moving a bathroom above a neighbour's living room, building code LBN 200-21 allows it if the soundproofing requirements are also met. For moving a bathroom, check whether a construction notice is needed (simplified renovation). This is one of the questions to check before replanning.
Order of work for a wall lining
- Choice You decide which wall, ceiling or floor to treat and how thick a layer the room can afford.
- Electrics Sockets and switches on this wall are moved to the new lining.
- Frame UW profiles are fixed to the floor and ceiling, and CW studs are placed between them.
- Insulation Insulation material is laid between the profiles.
- Plasterboard The frame is clad with boards.
- Finishing The joints and the surface are skimmed and painted.
What to write in the request
- Which room and which surface: wall, ceiling or floor.
- What disturbs you: voices, music, footsteps.
- The room dimensions and the ceiling height.
- The building series or year.
- Whether there are sockets, a radiator or pipes on the wall.
How much soundproofing costs
Soundproofing is priced by estimate. The nearest public prices: a plasterboard partition wall from €12/m² (insulation, skimming and painting separately), plasterboard or suspended ceilings from €15/m², skimming from €10/m², painting from €4/m², a socket or light point from €12 per point. Prices are for labour. Materials are calculated separately in the estimate.
The price is affected by the surface area in m², the chosen construction and the thickness of the insulation, the condition of the walls, floors and ceilings, how many sockets and light points must be moved, and the chosen finish. An exact estimate can be made after seeing the apartment. All prices: renovation prices.
