Soundproofing Insulation for Homes, Condos and Businesses
Noise is the number-one complaint in San Francisco's dense neighborhoods — footsteps from the unit upstairs, conversations through a shared wall, traffic on a busy corridor, the home office next to the kids' playroom. Sound travels two ways: through the air via gaps and cracks, and through the structure via vibration. USA Spray Me attacks both. Open-cell spray foam seals the air paths and absorbs airborne sound; dense acoustic batts and cellulose add mass and damping; and where needed we combine them with resilient channel, mass-loaded vinyl and double-layer drywall for a full assembly.
We soundproof single-family homes, condos and duplexes, apartment buildings, home theaters and recording studios, offices and conference rooms, medical suites and restaurants throughout the Bay Area.

| Material | How it works | Best for | Typical STC gain* |
|---|---|---|---|
| Open-cell spray foam | Seals air leaks, absorbs airborne sound, also insulates | Exterior walls, ceilings, irregular cavities, studios | +5 to +8 |
| Acoustic mineral wool | High-density absorption, fire-rated | Interior partitions, party walls, kitchens | +7 to +10 |
| Acoustic fiberglass batts | Economical absorption | Interior walls, home offices | +5 to +8 |
| Dense-pack cellulose | Mass + absorption in closed cavities | Between floors in condos, existing walls | +6 to +9 |
| Full assembly (insulation + resilient channel + 5/8" drywall ×2) | Decoupling + mass + absorption | Theaters, studios, bedrooms on busy streets | +15 to +25 |
Where We Install Soundproofing
- Shared walls between condos, duplexes and townhomes
- Ceilings and floors to stop footstep and impact noise from the unit above
- Exterior walls on Van Ness, 19th Avenue, Lombard, I-880 and other high-traffic corridors
- Home offices, nurseries and bedrooms for privacy and sleep
- Home theaters, music rooms and recording studios
- Offices, conference rooms and medical suites for speech privacy
- Mechanical, laundry and utility rooms to contain equipment noise
Honest Expectations
Insulation alone makes a real, noticeable difference to voices, TVs and everyday airborne noise, and it is the most cost-effective first step. Deep bass, heavy footsteps and street rumble travel through the framing and need decoupling and mass as well — we will tell you up front which level of treatment your goal requires, and we can install the complete assembly including drywall.
Added Benefit: Thermal Performance
Every soundproofing material we install also insulates. Open-cell foam in an exterior wall cuts drafts and energy bills while it quiets the room; cellulose between floors keeps the downstairs unit warmer. You get two upgrades for one installation.
