How do I soundproof my house from outside noises?
With out tearing apart your home one solution we have had success with over the years is the installation of Silent FX drywall and Green Glue over the top of your existing drywall.
Sealing the gap at the base of the wall with baseboards removed and prior to new drywall installed is an big area for sound transmission.
Any gaps around your windows and wall outlets will need to be addressed as well.
If your house has enough internal space, you could apply a soundproofing material (like Sonopan) over the drywall and finish with another layer of drywall on top. Just mind that everything on the walls needs to be reworked (Light switches, power outlets...) Doors and windows replaced by others with better STC (Sound transmission class) would contribute to a better final result. For a more budget friendly approach, a second layer of drywall with green glue between the old layer and the new one might help (but it's not going to solve the problem completely). Other option would be to consider investing only in the bedrooms / tv room for example.
