My experience soundproofing a victorian conversion ceiling

I don't see many success stories on Reddit, so I wanted to share our experience :)

We live in a 1880's well kept victorian conversion building with three flats and we're the middle flat. There was some soundproofing installed (I imagine some basic resilient bar system) prior to us purchasing the flat, but our bedroom was not soundproofed. This meant we heard footsteps, wardrobe doors closing, etc. from the bedroom above. We only heard talking if it was very loud.

We love the flat for the high ceilings, double aspect views, and neighbourhood. I've been wanting to soundproof this room as a test for other rooms so.... We eventually spent the money c.£6k (5M x 4M) using our trusted builder to build a decoupled metal hanging frame with - 2x soundproof plasterboard, MLV50, rockwool, isolation strips, and acoustic sealant. It also included plastering, painting and making good for the whole room. We gave up around 15 to 20cm in ceiling height.

I got a few quotes and am aware what I paid is considered expensive. I wanted to go with someone who had done work for us before and we trusted.

My thoughts after 2 months

1. It's dampened the footsteps noticeably where its no longer disruptive. It went from loud thud to a muted thud. I sleep with ear plugs and I can't hear anything.

2. Given the building's age, there will always be some resonance that comes through other channels but that's unavoidable. You just have to accept this with old buildings.

3. Was it worth the money? Depends what you value; for me, absolutely. I really value a bedroom where it's quiet and footsteps do really bother me. It was never going to eliminate the sound, so don't go into it with this expectation.

I'm guessing if I want to do the rest of my flat, it'll cost between £10-15k, which I think is worth it.

Happy to answer any questions about specs and experience. I hope this post can shine some positivity on soundproofing experiences.

We also visited our friends flats in other London neighbourhoods (Islington, South kensington, etc) and all converted flats have the same issue regardless of how nice the neighbourhood is.
