How To Soundproof Stairs

Stairs are a common source of noise in many homes, especially if they are made of wood or metal. The sound of footsteps, creaks, and squeaks can be annoying and disruptive for the people living in the house or the neighbors. How can you reduce the noise from your stairs and enjoy a more peaceful environment?

The answer is to soundproof your stairs using some simple and effective methods. Soundproofing stairs involves adding materials that can absorb or block the sound waves from traveling through the stair structure. Some of the materials you can use are carpet, rubber mats, acoustic foam, mass loaded vinyl, and green glue. These materials can help you create a quieter and more comfortable space in your home.

In this article, you will learn how to soundproof your stairs using these materials and some tips and tricks to make the process easier and more efficient. You will also learn about the benefits of soundproofing your stairs and how it can improve your quality of life.

Common Noise Issues with Stairs

There are a few main reasons stairs can transmit noise in a home:

  • Hard surfaces – Hard materials like wood, tile, concrete, and metal easily propagate noise. Footsteps on bare hard stairs can be very loud.
  • Lack of absorption – Stairs often don’t have any sound absorbing materials. This allows noises to echo and travel farther.
  • Flanking paths – Stairs connect floors in a home, providing a direct path for noise to travel up and down.
  • Thin walls/ceilings – Stairwell walls connecting floors are often thinner and transmit more noise if not insulated properly.

Reducing noise flanking via the stairs and adding sound absorption are key to soundproofing them effectively.

Soundproofing Materials for Stairs

There are a variety of materials that can be used to soundproof stairs:

  • Carpeting – Carpet and padded carpet are very effective at absorbing noise from footsteps. Carpeting hard surface stairs is one of the simplest soundproofing solutions.
  • Underlayment – Specialized acoustic underlayments go under flooring materials to block noise transmission. Great for hard surface stairs.
  • Risers – Acoustic panels or insulation attached to stair risers block noise flanking between steps.
  • Treads – Sound absorbing treads reduce noise from footsteps and add mass to stairs.
  • Stair rugs – Like carpets but just for the stairs. Easy to install and come in versions for hard and carpeted stairs.
  • Enhanced drywall – Special soundproofing drywall like mass loaded vinyl or quiet rock for stairwells prevents noise flanking through walls.

Combining a couple of these materials is the most effective way to reduce stair noise. Now let’s look at specific methods for hard and carpeted stairs.

Soundproofing Hard Surface Stairs

Hard surface stairs made from wood, tile, metal and concrete transmit a lot of noise in a home. Here are great ways to reduce noise from hard surface stairs:

Install Noise Reducing Treads

Stair treads designed for soundproofing have a noise isolating layer and a durable textured surface for traction. Brands like Treadmaster and Kinetics Noise Control make excellent sound reducing treads that are easy to install right over existing stairs. This dramatically cuts down on noise from footsteps and other impacts.

Use Acoustic Underlayment

Acoustic underlayments like cork, felt, rubber, and foam go underneath flooring materials to block noise transmission. Installing an underlayment under new flooring can make a big difference. Combine with soundproofing treads for best results.

Add Risers to the Steps

Adding acoustic panels, mass loaded vinyl sheets, or insulation batts to stair risers creates a noise barrier between steps. This prevents noises from moving up and down the staircase as easily. Seal perimeters with acoustic caulk for best performance.

Carpet the Stairs

Carpet and padded carpet completely transforms hard surface stairs. The dense padding absorbs noise while the carpet adds a bit of mass. This is the easiest and often cheapest way to reduce stair noise. Use high-quality, dense carpet padding for maximum sound absorption.

Build a New Staircase Box

One advanced solution is to build an entirely new staircase box within the existing stairwell. Use double stud walls filled with insulation, multiple layers of quiet rock drywall, and a floating staircase separated from walls and stringers. This significantly blocks flanking noise but is more complex and expensive.

Soundproofing Carpeted Stairs

Carpeted stairs are already pretty quiet thanks to the sound absorbing carpet pad. But some additional tweaks can further reduce noise:

Upgrade the Carpet Pad

Old thin carpet padding may not absorb much sound. Upgrading to a thick high-density carpet pad can improve sound absorption and reduce noise transmitted through stairs.

Install Acoustic Risers

Adding acoustic panels, mass loaded vinyl, or insulation batting to carpeted stair risers will prevent flanking between steps. Perimeter caulking around panels helps block sound leaks.

Use Larger Carpet

Extending carpet past the stair edges to cover landings and upper wall areas increases overall sound absorption in the stairwell. The more continuous carpet, the better.

Add Stair Rugs

Specialty acoustic stair rugs designed for carpeted stairs add another layer of noise absorption and mass. Brands like Ruggripper make stair rugs with non-slip backing perfect for existing carpeted stairs.

Replace Treads with Soundproof Versions

As treads wear out, replace them with soundproofing stair treads which include extra noise isolating layers. This further limits hard surface noise transmission between steps over time.

Installing Stair Soundproofing Materials

To properly install stair soundproofing materials:

  • Thoroughly clean stairs first and remove any debris or dirt. This ensures materials adhere properly.
  • Follow manufacturer instructions for installation. Many materials have ideal adhesives or techniques to follow.
  • Cut materials to tightly fit each step and riser area. Gaps or exposed hard surfaces allow flanking noise.
  • Seal all seams and perimeters with acoustic caulk. This prevents noise leaks and isolates materials.
  • Use care on stair edges so materials are flush and even. Avoid tripping hazards.
  • Work methodically step-by-step for best results.

It also helps to remove old nosy boards and replace with quieter composite steps when possible.

Proper installation is important for getting the full noise reduction benefits. Take your time and do it right.

Soundproofing Staircases on a Budget

Soundproofing stairs can be done for very little money in some cases:

  • Use area rugs – Large area rugs at stair tops and bottoms add mass and absorption.
  • Install carpet remnants – Use any leftover carpet scraps or remnants to cover bare stairs temporarily.
  • Felt furniture pads – Stick self-adhesive felt pads under stair edges as cheap risers.
  • Towels – Roll up old towels and place under stair nosings to absorb noise.
  • DIY risers – Make simple risers from roxul insulation wrapped in fabric or mass loaded vinyl.
  • Remove debris – Completely clear out debris under stairs and add any insulation.

These DIY solutions can make a decent improvement for nearly free. Compare costs to pick the cheapest effective option for your needs.

Soundproofing Stairwells and Landings

It’s also important to soundproof the actual stairwell space to prevent noise flanking between floors.

  • Seal and caulk wall penetrations thoroughly. This includes around wiring, plumbing, vents, lights etc.
  • Install acoustic noise absorbing panels on stairwell walls to limit echo and reverberation.
  • Use multiple layers of quiet rock and sound clips on walls for maximum isolation between floors.
  • Add a floor door or ceiling door at stairwell entry points to contain noise.
  • Seal under stairwell doors and weatherstrip to prevent noise leaks.

By combining stair treatments with full stairwell soundproofing, you can block noise in all directions.
