How much would a comprehensive soundproofing assessment and remediation plan cost for my whole home?

A comprehensive whole-home soundproofing assessment and remediation plan in Ottawa typically costs $800 to $2,500 for the assessment alone, with the remediation work itself ranging from $15,000 to $60,000+ depending on the size of the home, the severity of the noise issues, and the target performance levels. The assessment is an investment that almost always pays for itself by identifying the most cost-effective solutions and preventing you from spending money on treatments that would not address your actual noise problems.
A professional acoustic assessment involves several stages. The consultant visits your home and conducts baseline noise measurements using a calibrated sound level meter, measuring ambient noise levels in each room and identifying the dominant noise sources and transmission paths. They will test walls, floors, and ceilings to estimate existing STC and IIC ratings, identify flanking paths through ductwork, plumbing, and structural connections, and document every weak point including doors, windows, electrical penetrations, and gaps. The deliverable is a detailed written report with prioritized recommendations — telling you exactly what to fix, in what order, with estimated costs and expected performance improvements for each intervention. A basic assessment covering one or two problem rooms runs $800–$1,200, while a full whole-home assessment with detailed measurements and a comprehensive written plan costs $1,500–$2,500.
What Remediation Typically Involves
For a typical Ottawa home — say a 2,000 square foot two-storey in Kanata, Barrhaven, or Orleans — a comprehensive remediation plan might include: upgrading party walls or exterior walls with sound isolation clips, mineral wool, and double drywall with Green Glue ($15–$25 per square foot); replacing hollow-core doors with solid-core doors and acoustic seals ($400–$800 each); addressing windows with acoustic glass or interior inserts ($500–$1,500 per window); sealing all penetrations with acoustic caulk and putty pads ($2,000–$4,000 whole-home); and treating the basement ceiling if finished living space is below ($8–$18 per square foot). The total remediation for a moderate whole-home project typically falls in the $25,000–$45,000 range, with simpler projects as low as $15,000 and complex heritage homes or multi-unit conversions reaching $60,000 or more.
The key advantage of starting with a professional assessment is prioritization. Most homes have two or three critical weak points that account for 70–80% of the noise problem, and fixing those first delivers the biggest improvement per dollar spent. A consultant might find that your biggest issue is a shared HVAC duct path that can be solved for $1,500, saving you from unnecessarily rebuilding entire walls. Ottawa's older housing stock — particularly in Sandy Hill, the Glebe, and Centretown — often has hidden sound transmission paths through balloon-framed walls, shared chimneys, and uninsulated floor cavities that are not obvious without professional investigation. The Ontario Building Code sets minimum STC 50 for party walls, but an assessment will tell you what your walls actually achieve today and what it will take to reach your comfort goals.
