Soundproofing in Laval and on the North Shore

Can you hear your neighbours walking, talking or playing music? Travaux Experts soundproofs ceilings, floors and walls, particularly in plexes and older buildings, to bring peace and quiet back to your home.

Airborne or impact noise: identifying the right problem

Effective soundproofing starts with identifying the type of noise. Airborne noise travels through the air: voices, music, television or traffic. Impact noise travels through the structure: footsteps, scraping chairs and slamming doors. Each type calls for its own solution, often combining both approaches. That is why we assess your situation before recommending work.

Plexes and older buildings

Soundproofing plexes and older buildings

In duplexes, triplexes and buildings built before the 1980s, noise travels easily between units. These buildings often have:

  • wood floors laid directly on joists, without insulation
  • cracked lath-and-plaster ceilings
  • little or no insulation between units
  • ductwork and plumbing that transmit sound
  • fire separations requiring upgrades

Fortunately, complete demolition is not always necessary. We add a suspended ceiling on resilient channels, stone wool and 5/8-inch drywall, one unit at a time, with as little disruption to tenants as possible. Your units become more comfortable and easier to rent.

Ceilings

Soundproofing ceilings against noise from above

The ceiling is often the priority, since that is where footsteps and voices come through. Here is our approach:

  • first, remove the existing ceiling if needed to access the joists
  • then, fill the cavity with Safe’n’Sound stone wool without compressing it
  • next, install resilient channels or vibration-isolating hangers
  • install one or two layers of 5/8-inch drywall, with acoustic sealant around the perimeter
  • finally, address recessed lights and other openings

The ceiling is thereby isolated from the structure and transmits far fewer vibrations, in accordance with the Québec Construction Code.

Floors

Reducing impact noise through the floor

Do you live upstairs and want to be considerate of your downstairs neighbour? The floor is the best place to stop impact noise at its source. Our options include:

  • an acoustic membrane beneath the new flooring
  • a cork or recycled-rubber underlay
  • stone wool between the joists when the ceiling below is open
  • a floating floor isolated from the walls

We often combine floor and ceiling work for the best result between two units.

Walls

Soundproofing a shared wall, bedroom or basement

For a shared wall, bedroom, office or playroom, we use:

  • Safe’n’Sound or ComfortBatt stone wool between the studs
  • Sonopan wood-fibre panels to reduce vibrations
  • resilient channels or staggered studs
  • a double layer of 5/8-inch drywall
  • acoustic sealant around outlets and openings

As a result, most voices and music no longer pass through the wall.

Materials and techniques

Everything you need to know about soundproofing

Airborne noise travels through the air: voices, music and television. Reducing it requires mass, such as a double layer of drywall, and sound-absorbing materials, such as stone wool.

Impact noise comes from a shock to the structure: footsteps, falling objects and sliding furniture. Reducing it requires isolation, using resilient channels, an underfloor membrane or a floating floor, for example.

Rockwool Safe’n’Sound stone wool is designed for the acoustics of interior walls and ceilings. ComfortBatt primarily insulates exterior walls while also helping reduce noise.

Sonopan panels, made from recycled wood fibre, are installed beneath drywall. They reduce a significant portion of vibrations and improve wall and ceiling soundproofing.

Resilient channels and vibration-isolating hangers separate the drywall from the structure. As a result, far fewer vibrations travel from one room to another.

We also build recording studios, podcast rooms and rehearsal rooms, with suitable soundproofing and acoustic treatment.

We soundproof conference rooms, private offices and commercial premises to ensure privacy and employee comfort.

Case study

A soundproof drum room in a garage

In 2023, we built a 9-by-13-foot soundproof room at the back of a garage while keeping space for an electric truck and its charging station. The goal: play drums, congas and music at any hour without disturbing the neighbours.

  • foundation walls lined with stone wool and drywall
  • an isolated ceiling beneath ventilation ducts and sprinklers
  • a sealed vapour barrier as required by the Code in a garage
  • a solid, self-closing door with airtight weatherstripping

The result: the client can play even late at night with peace of mind.

Testimonials

What our clients say about our soundproofing projects

An impeccable turnkey solution

I would like to thank the entire Travaux Experts team for their great work. They completed several projects during the 2022 season: repairing 150 linear feet of water line, rebuilding 600 square feet of paving, replacing 200 linear feet of fencing and resurfacing 1,200 square feet of asphalt. It was quite a big project… A turnkey solution. Impeccable!
