Need to know if I'm being unreasonable, we're in a new build so small garden which backs onto the side of another house. The teenage daughter in this house has recently taken up acoustic guitar which is great, all for kids being off screens! Issue is her playing is becoming constant, working from home it sounds like she's in the house playing with our windows closed (hers open). I've not mentioned anything so far as I know I don't have a cause to say anything as it's not antisocial hours or anything. Issue is tonight she's practicing now and our in our kids bedrooms whilst they're trying to sleep and you can hear it pretty loudly with the windows closed. I get it's a heatwave so she'll want her window open but would I be unreasonable to say anything? I'm friendly with her parents (ironically they had a noise issue with another neighbour which was also affecting us last year and was sorted) so wondering if I casually mentioned it, would it be okay? Any advice welcome! We're looking to move in the next couple of years as the sound proofing in this particular new build is pretty awful 🙃
