FAQ

Sound Board & Acoustic Insulation South Portland ME — Common Questions

Massachusetts requires a minimum STC 50 for walls and floors between dwelling units in multifamily residential buildings under 780 CMR. Many quality South Portland buildings target STC 55–60 for comfortable sound separation.

Partially. Adding a layer of sound board over existing drywall with resilient channel and acoustic sealant can add 5–10 STC points without full removal. For significant improvement, a proper decoupled assembly with new drywall is more effective.

Acoustic wall systems in South Portland typically cost $3.50–$7.00 per square foot installed depending on the target STC and system complexity. Contact 857-214-2434 for a free estimate for your South Portland project.
