What should I budget for a full ceiling and wall soundproofing package for a condo unit in Westboro?

For a full ceiling and wall soundproofing package in a Westboro condo, you should budget between $18,000 and $45,000 depending on the unit size, current construction, and target STC rating. A typical Westboro condo unit — say 800 to 1,100 square feet — shares walls with neighbours on one or two sides and has a ceiling that transmits footfall noise from above. Addressing all of these surfaces with a professional-grade assembly is a substantial project, but it is the only way to achieve meaningful, whole-unit noise reduction.
The wall portion typically involves installing sound isolation clips (RSIC-1 or equivalent) with hat channel, filling the cavity with Rockwool Safe'n'Sound mineral wool, applying Green Glue compound between two layers of 5/8-inch Type X drywall, and sealing every edge and penetration with acoustic caulk. For shared party walls, this assembly achieves STC 55 to 60, well above the Ontario Building Code minimum of STC 50. At $15 to $25 per square foot installed, the wall work for two shared walls in a typical unit runs $5,000 to $12,000. If you need all four walls treated (for example, a corner unit where exterior road noise from Richmond Road is also an issue), double that figure.
The ceiling is usually the more expensive and more critical component, especially in Westboro's mid-rise condo buildings where footfall and impact noise from above is the primary complaint. A proper ceiling assembly uses isolation clips suspended from the existing ceiling joists, hat channel, mineral wool, Green Glue, and double 5/8-inch drywall. This runs $12 to $22 per square foot installed and typically costs $10,000 to $22,000 for a full unit ceiling. You will also lose about 2 to 3 inches of ceiling height, which matters in older Westboro buildings where ceilings may already be at 8 feet.
Do not forget the often-overlooked details that can undermine the entire investment: acoustic putty pads around every electrical box ($3 to $6 each), solid-core doors to replace any hollow-core interior doors ($250 to $500 each installed), and HVAC duct lining or silencers if sound is flanking through the ventilation system ($500 to $2,000). Ottawa labour rates for this specialty work are 10 to 15 percent below Toronto, which is a meaningful saving on a project of this scale. Always ensure your contractor specifies exact materials in the quote — generic descriptions like "soundproof insulation" are a red flag. For a whole-unit project in Westboro, it is well worth having a soundproofing specialist assess the existing construction before committing to an approach.
