How to Soundproof a Semi Detached Home in Scarborough

Why soundproofing matters in a semi-detached home
Semis share one wall with another household, which can transmit airborne and structural sound. Whether it’s footsteps, music, or plumbing noise, proper soundproofing improves comfort and property value. Scarborough’s mix of older and newer semis means your approach might differ based on the home’s age and layout.

Top methods to soundproof a semi-detached home
1. Add mass to the shared wall
Use double layers of drywall with Green Glue damping compound between them. The added weight blocks more airborne noise. This is ideal in older Scarborough semis with thinner plaster walls.
2. Install acoustic insulation
Fill stud cavities with mineral wool or fiberglass insulation. These absorb vibrations within the wall. Great for homes being renovated in areas like Birch Cliff or Wexford-Maryvale.
3. Decouple the wall structure
Use resilient channels or sound clips to separate drywall from studs. This prevents sound from traveling directly through the structure. A contractor from the Get Aldo team’s network can connect you with trusted local pros.
4. Seal gaps and air leaks
Use acoustic caulk around outlets, trim, and ceiling joints. Even small gaps can let sound travel. It’s a quick win if you’re not ready for full renovations.
5. Soften interior reflections
Noise bounces inside rooms too. Add rugs, drapes, and upholstered furniture — especially useful for condos or townhomes nearby with shared walls.

Local Scarborough considerations
Older areas like Clairlea-Birchmount and Birch Cliff often have plaster or cinder block walls that transmit low-frequency sound differently than drywall. You might need specialized materials or pro installation.
