How much should I budget for soundproofing drywall in a Scarborough home music studio to meet neighbour noise standards?

For a dedicated home music studio in Scarborough, you should budget between $8,000 and $18,000 for a comprehensive drywall-based soundproofing package covering all four walls and the ceiling, depending on the room size and the level of isolation you need. A basic improvement that reduces casual noise complaints will sit at the lower end, while a properly isolated room suitable for amplified instruments or recording will push toward the higher end.

The target you're aiming for is an STC rating of 55-60 or higher for the walls and ceiling. For context, a standard interior wall with single-layer 1/2-inch drywall on each side rates around STC 33-35 — you can hear normal conversation clearly through that. At STC 50, loud speech is barely audible. At STC 60, most sounds including amplified music are reduced to a faint hum. The Ontario Building Code requires STC 50 between dwelling units in multi-unit buildings, but for a music studio in a detached or semi-detached Scarborough home, there's no specific code requirement — your target is driven by practical neighbour relations and your own comfort.

What a Professional Studio Assembly Looks Like

The gold standard for a home music studio involves decoupled double-layer drywall with damping compound on all surfaces. Here's what that breaks down to in GTA pricing:

Walls typically get resilient channel installed horizontally at 16 or 24-inch spacing, then a first layer of 5/8-inch Type X drywall ($20-$28 per sheet), two tubes of Green Glue per sheet ($36-$50 per sheet in compound), and a second layer of 5/8-inch drywall on top. This assembly achieves STC 52-56 when done correctly. For even higher isolation, contractors may build an independent stud wall with a 1-inch air gap from the existing wall — this "room within a room" approach can hit STC 60-65 but costs significantly more due to the additional framing and lost floor space.

The ceiling is the most critical and expensive surface because sound travels upward through floor joists to the rooms above. Resilient channel on the ceiling joists, followed by a double layer of 5/8-inch drywall with Green Glue between layers, is the standard approach. For a music studio, many GTA contractors recommend adding mineral wool insulation (Roxul Safe'n'Sound, about $1.20-$1.80 per square foot) in the joist cavities above before installing the resilient channel. Ceiling soundproofing runs $5.00-$10.00 per square foot installed due to the difficulty of overhead work and the weight of double drywall layers.

For a typical Scarborough home studio room of 150-200 square feet, here's a realistic budget breakdown. Materials including double-layer drywall, Green Glue, resilient channel, mineral wool insulation, acoustical caulk for sealing perimeters, and all taping supplies will run $2,500-$5,000. Labour for installation, taping, and Level 4 finishing typically runs $4,000-$8,000 depending on the complexity. Extending electrical outlets through the new wall thickness adds $500-$1,500. A solid-core or acoustically rated door (the weakest link in any soundproofed room) runs $800-$2,000 installed. Sealing all penetrations, outlets, and gaps with acoustical caulk is included in most contractor quotes but is absolutely critical — sound leaks through any unsealed gap.

One detail that catches many Scarborough homeowners off guard is flanking paths. Sound doesn't just go through walls — it travels through HVAC ducts, electrical boxes back-to-back on shared walls, gaps under doors, and structural connections at the floor and ceiling. A proper music studio build addresses all of these, which is why the cost adds up. An experienced soundproofing contractor will seal every electrical box with putty pads, install acoustical caulk at every perimeter joint, and may recommend duct silencers for any HVAC serving the room.

Many post-war Scarborough homes from the 1950s-1970s have basements that make ideal music studio locations because the concrete foundation walls already provide substantial mass-based sound isolation to the outside. You'd primarily need to address the ceiling (sound to the floor above) and any above-grade walls. This can bring the budget down to $5,000-$10,000 since the concrete does much of the heavy lifting.

This is entirely a professional project — the resilient channel installation alone requires precision that determines whether the entire investment works or fails.
