Where Noise Gets In

Empty wall cavities can allow sound to travel easily through your home. Hollow walls can act like a drum, carrying noise from outside and allowing sounds to travel between rooms.
Filling those cavities with dense injected foam adds mass to the wall and helps reduce the air path that allows noise to travel.
The result can be a quieter, more comfortable home without rebuilding your walls.

The Bonus: Quieter + Better Insulated

The same foam that helps reduce noise also provides insulation inside your wall cavities.
That means you’re not installing insulation just for noise reduction. Filling empty or under-insulated walls can also help cut heating bills, improve comfort, reduce drafts, and potentially qualify your project for available rebates.
One project can address both comfort and noise.

How It Works

Drill

We make small, carefully placed holes through your siding or mortar joints to access the wall cavities. There's no need to remove your interior drywall.

Fill

We check each cavity with a rod before filling, then inject foam into the wall. The foam expands through the available cavity, helping fill empty spaces and add density to the wall.

Patch

After the cavities are filled, we plug and patch the access holes the same day. Your interior walls stay intact, and there is no major remodeling project.

See the Difference

We use blower door testing and thermal imaging before and after qualifying projects so you can see what changed.
Thermal imaging can help show temperature differences across the walls, while blower door testing helps identify air leakage.
It’s a practical way to see the insulation improvements rather than simply taking our word for it.

  • FAQ

Frequently Asked Questions

Will this reduce traffic and road noise?
It can help reduce noise traveling through exterior wall cavities, including some traffic and road noise. However, the amount of noise reduction depends on the home’s construction and other areas where sound can enter, such as windows and doors.
Yes. Filling hollow wall cavities can help reduce noise traveling from one room to another. It won’t eliminate every sound, but it can make rooms quieter.
No. Injected foam is designed to reduce noise, not eliminate every sound. Noise can still travel through windows, doors, floors, ceilings, and other parts of the building.
Many wall insulation projects can be completed in one day; two-story homes or anything over 1,400 sq ft take two. We’ll give you a more accurate timeline after evaluating your home.
The cost depends on your home’s size, wall construction, accessibility, and the amount of insulation needed.
