Residential Soundproofing

Residential soundproofing in Ottawa addresses the full spectrum of noise challenges homeowners face, from airborne sound transmission through walls and ceilings to impact noise travelling through floors. Ottawa's diverse housing stock demands tailored approaches depending on the age and construction type of your home.

Heritage properties in the Glebe, Sandy Hill, and New Edinburgh often feature plaster-and-lath walls and original hardwood floors that transmit sound readily between rooms and between units in converted duplexes. These homes require careful treatment that preserves architectural character while dramatically improving sound isolation, often using decoupled wall assemblies and mass loaded vinyl barriers installed behind new drywall layers.

Meanwhile, newer suburban builds in Kanata, Barrhaven, and Stittsville frequently use single-layer drywall on builder-grade steel studs with minimal insulation, resulting in STC ratings well below the Ontario Building Code minimum of STC 50 for separating walls between dwelling units. Upgrading these assemblies with resilient channels, acoustic insulation batts such as mineral wool or fibreglass, and double drywall with Green Glue damping compound can push performance to STC 55 or higher.

Ottawa's extreme temperature swings, from minus thirty in January to plus thirty-five in July, cause significant expansion and contraction in building materials, making proper detailing of acoustic seals and caulking critical to long-term performance. Floor treatments for impact noise reduction include acoustic underlayments beneath hardwood or laminate, floating floor assemblies, and ceiling isolation clips installed from below.

A whole-home soundproofing plan considers HVAC ductwork as a flanking path and addresses noise transfer through outlets, plumbing penetrations, and gaps around doors. Every residential project begins with a room-by-room assessment to identify the weakest links in your sound isolation chain and prioritize improvements that deliver the greatest noise reduction per dollar spent.
