Burbank Remodeling Contractor builds soundproof rooms in Burbank, California. This city sits between Warner Bros., Disney and Universal, and a large share of the people who live here work in production. That produces a specific kind of request: a room that can hold a mix at real volume without the neighbors calling, a screening room that performs acoustically, or a home office where a call cannot be heard through the wall.
Soundproofing is construction, not treatment. Foam panels on a wall change how a room sounds inside itself and do essentially nothing to stop sound leaving it. Stopping transmission means mass, decoupling, absorption in the cavity and sealing every penetration. Call (747) 330-0305 and tell us what has to be inaudible and from where.
How Sound Isolation Actually Works
Four things stop sound moving through an assembly: mass, decoupling, damping and airtightness. Mass means heavy layers, typically multiple sheets of drywall. Decoupling means the two sides of the wall do not touch, achieved with staggered studs, a double stud wall or resilient channel and isolation clips. Damping means a viscoelastic layer between drywall sheets that turns vibration into heat. Airtightness means every gap sealed, because sound follows air.
Low frequencies are the hard part and the reason cheap approaches fail. A kick drum or a subwoofer travels through structure, so a room that is not decoupled from the framing will transmit bass into the rest of the house regardless of how many layers of drywall it has.
Types of Rooms We Build
Home Recording and Mixing Rooms
The most demanding. Genuine isolation from the rest of the house, a room-within-a-room where the budget allows, quiet mechanical ventilation, and interior acoustic treatment tuned to the room's dimensions rather than applied by the square foot.
Screening Rooms and Home Theaters
Sightline and seating riser geometry worked out before framing, light control at every surface, in-wall speaker backing boxes framed in during construction, and enough dedicated circuits and conduit for equipment that will change three times over the room's life.
Soundproof Home Offices and Edit Bays
The most common request since 2020. The bar is lower than a mixing room, because the goal is call privacy in both directions, and a well-executed decoupled wall with a solid-core door and a proper seal usually does it.
Garage and ADU Conversions for Studio Use
A detached garage is often the best candidate on the lot, since it is already separated from the house's structure. It needs insulation, isolation, a real HVAC solution and, where it will be occupied as living space, the full conversion path.
Ventilation, Doors and Where Isolation Leaks
A sealed room needs mechanical ventilation, and a standard duct run is an open channel for sound between rooms. The solution is lined baffle boxes, low air velocity and a duct path with bends rather than a straight shot, all of which have to be designed into the room rather than added afterward.
The door is the other weak point and it is where most home projects fail. A hollow-core door in a standard jamb undoes an expensive wall. The fix is a solid-core or purpose-built acoustic door with full perimeter seals and a drop seal at the threshold, and in serious rooms two doors with an air gap between them. Electrical boxes, recessed lights and any penetration through the assembly all need to be sealed or backed.
Spend the money on the wall assembly, the door and the ventilation. Foam panels can be added in an afternoon later, and they were never the thing keeping sound in.
Planning a Studio Build in a Burbank House
Two structural realities shape these projects here. First, decoupled assemblies eat space, commonly six to twelve inches off each wall plus the ceiling, which is a lot in a room that started at eleven by thirteen. Second, all that added drywall is heavy, and a ceiling assembly hung from existing joists may need framing reinforcement.
Room dimensions matter acoustically too. Rooms with dimensions that are simple multiples of each other produce standing waves that no amount of treatment fully fixes. Where we have any freedom in the framing, we set the dimensions deliberately at the start, which costs nothing at framing and cannot be corrected later.

Call (747) 330-0305Frequently asked questions
Can you soundproof a room that is already finished?
Partially, and honestly the results are limited. Adding mass and a damping layer over existing drywall helps at mid and high frequencies. Real isolation, especially at low frequencies, requires decoupling, which means opening the walls. We will tell you what a surface-level approach will and will not achieve before you spend anything.
How much space does soundproofing take?
For a serious room, plan on losing four to six inches per wall for a decoupled assembly, more for a full room-within-a-room, and several inches of ceiling height. In a small room that changes the usable dimensions enough to be worth modeling before you commit.
Do I need a permit for a home studio?
For framing changes, added electrical circuits and HVAC modifications, yes. The added weight of a heavy ceiling assembly can also require a structural review. Converting a garage to occupied space brings the full conversion requirements.
Will this stop my neighbors from hearing a subwoofer?
It can, with the right assembly, and that specific goal is what separates a real budget from an optimistic one. Low-frequency isolation needs mass and decoupling on every surface including the floor, and in a detached structure it usually means a floated floor. Tell us the honest volume target at the start and we will tell you what it takes.
