Soundproofing renovations in Ottawa cost between $1,000 for a single room with basic treatment to $20,000+ for comprehensive whole-home soundproofing. The most common projects are home office soundproofing ($2,000-$6,000), bedroom sound isolation ($2,000-$5,000 per room), basement ceiling soundproofing ($3,000-$8,000), home theatre room ($5,000-$15,000), and party wall soundproofing in townhouses and semis ($3,000-$10,000). Soundproofing is increasingly important in Ottawa as more people work f...
Adding a second layer of 5/8-inch drywall with Green Glue compound ($3-$6/sq ft installed) is the most popular wall soundproofing method. The damping compound converts sound energy to heat, reducing transmission by 10-15 decibels. This approach adds minimal thickness (less than 1 inch) to the wall. Resilient channel + drywall ($4-$8/sq ft) decouples the new drywall layer from the existing wall structure, breaking the vibration path. Combined with insulation in the wall cavity, this provides 15-...
Ceiling soundproofing in basements and between floors is the most common residential soundproofing project in Ottawa. The approach depends on whether you're dealing with airborne sound (voices, TV) or impact sound (footsteps, dropped objects) — or both. For airborne sound: add mineral wool batts (Roxul/Rockwool Safe'n'Sound) between floor joists ($2-$4/sq ft), install resilient channel on the ceiling joists ($1-$2/sq ft), and attach two layers of 5/8" drywall with Green Glue ($3-$6/sq ft). Tota...
Windows are often the weakest link in exterior noise control. Standard double-pane windows provide STC 28-32. Upgrading to laminated glass (one pane has an acoustic interlayer) improves to STC 34-38 at an additional $50-$100 per window. Interior storm windows ($200-$500 per window) add a second barrier with an air gap, providing STC 40-45 when combined with the existing window. This is the most cost-effective approach for reducing street noise, construction noise, and neighbour noise. Solid-co...
Home office: focus on the door (solid-core with seals), add a layer of drywall with Green Glue to shared walls, and use acoustic panels for echo reduction. Budget: $2,000-$6,000. This investment pays for itself in improved focus and professional video call quality. Home theatre: comprehensive treatment including walls (double drywall with Green Glue on resilient channel), ceiling (same treatment), door (acoustic or solid-core with seals), and acoustic panels for internal sound quality. Budget: ...
A single room costs $2,000-$6,000 for effective soundproofing. Basement ceiling soundproofing costs $3,000-$8,000. Home theatres cost $5,000-$15,000. Whole-home soundproofing can exceed $20,000.
Adding a second layer of drywall with Green Glue compound provides the best balance of cost and effectiveness. For maximum results, combine this with resilient channel mounting and cavity insulation.
Yes, adding a second layer of drywall with Green Glue over existing walls is highly effective and doesn't require removing anything. Mass Loaded Vinyl is another surface-applied option.
Indirectly, yes. Soundproofed home offices, bedrooms, and entertainment spaces are attractive to buyers. Soundproofing that meets building code for secondary suites adds significant value by enabling legal rental income.
Ontario Building Code requires a minimum STC 50 between dwelling units. This typically requires mineral wool insulation, resilient channel, and double drywall between the units.
