Did something similar in our townhouse—went with sound insulation between shared walls. Helped a lot, but honestly, sealing gaps around doors and windows made just as big a difference. It's always the little things you don't expect...
Did a couple flips where soundproofing was a big selling point—my two cents:
- Insulation helps, but doesn't eliminate noise completely.
- Sealing doors/windows def underrated... cheap fix with noticeable results.
- Also check outlets and switch plates—surprising how much noise sneaks through those little openings.
"Sealing doors/windows def underrated... cheap fix with noticeable results."
Totally agree with this. Did a reno last year where we focused heavily on sealing gaps around windows and doors—made a huge difference, especially for street noise. Insulation helps, sure, but those little overlooked spots can really surprise you. Good call on the outlets too, never thought of that one... might have to try it next time.
