ᐅ Retrofitting Noise Insulation for Water Pipes

Hello :-)

I own an old house (built in 1900) that I live in, located in a former mining settlement. The houses are so close together that the neighbor’s washbasin drain pipes run directly through our shared wall. His bathroom is right next to our children's bedroom. The sound of running water is very loud. Now I am looking for a way to reduce the noise without having to tear down the wall. Does anyone have a good idea?

Best regards,
Marc

You will only be able to reduce the noise from the water pipes if you build a wall on the children’s room side in front of the party wall, designed for sound insulation (a plasterboard stud wall with a gap and no structural connection to the party wall, with a soundproofing mat in the space in between).

One solution, as already described, is to build a wall in front and fill it with soundproofing or insulation material. Of course, this is a very labor-intensive task. Sometimes, using sound-dampening wallpaper can also help. For example, soundproof wallpaper from Sempatech could be an option. You can still apply your own wallpaper or paint over it. This won’t be able to block all noises, but it will at least reduce the impact.

I have worked with soundproof wallpaper before. However, it did not make much of a difference. Therefore, building a wall in front of the existing one is probably the best solution. With appropriate insulation, the noise level should be significantly reduced.

Hi Louis, of course you can't eliminate all noises with this, but a significant reduction should be possible.
It always depends on how the wallpaper itself has been applied, as a number of mistakes can be made here.

I agree with that, as the workmanship is crucial here. Such wallpaper can be quite helpful and is easier to install than building a wall.
