What is the average cost of soundproofing drywall in Calgary in 2026?

Soundproofing drywall in Calgary typically costs $8-15 per square foot for materials and installation, with most homeowners spending $3,000-8,000 for a standard room. However, costs can vary significantly based on the level of soundproofing needed and the specific products used.

Basic soundproofing options include adding a second layer of 5/8" drywall with Green Glue damping compound between layers, which runs about $8-10 per square foot installed. This approach can reduce sound transmission by 8-12 decibels and works well for typical residential applications like home theaters or bedrooms adjacent to noisy areas.

Mid-range solutions involve specialized soundproof drywall like QuietRock or similar products, combined with resilient channels or sound clips to decouple the drywall from the framing. This approach costs $10-13 per square foot and can achieve 15-20 decibel reduction. These systems are popular for basement developments where you want to minimize sound transfer between floors.

High-performance soundproofing using mass-loaded vinyl (MLV), multiple drywall layers, staggered stud construction, and premium acoustic materials can cost $12-15+ per square foot. This level is typically used for recording studios, home theaters, or situations where maximum sound isolation is critical.

Calgary-specific factors that affect pricing include the city's competitive construction market and the popularity of basement developments in local homes. Many Calgary contractors are experienced with soundproofing basement suites and family rooms since finished basements are extremely common here. Winter scheduling can also impact costs, as interior work is in high demand during the cold months when exterior projects aren't feasible.

What's typically included in soundproofing quotes: removal of existing drywall (if needed), framing modifications, insulation upgrades, specialized drywall installation, taping and mudding, and primer coat. What's usually extra: final paint, electrical modifications to accommodate thicker walls, and HVAC adjustments if vents need repositioning.

Professional guidance is essential for effective soundproofing. The key is understanding what type of noise you're trying to control - airborne sound (voices, TV) versus impact noise (footsteps, dropped objects) require different approaches. A qualified drywall contractor can assess your specific situation and recommend the most cost-effective solution.

Next steps: Get quotes from experienced drywall contractors who can evaluate your space and noise concerns. Ask to see examples of previous soundproofing projects and request Sound Transmission Class (STC) ratings for their recommended systems. Remember that proper installation is crucial - even premium materials won't perform well if not installed correctly.
