Soundproofing a garage and turning it into a home recording studio is one of the most exciting upgrades you can make as a creator or musician. But, garages come with their own unique challenges: thin walls, drafty gaps, big hollow garage doors, and structural limitations.

In this guide, we’ll walk through everything you need to know before soundproofing your garage, including costs, pros and cons, the three pillars of sound isolation, and when a garage is or isn’t worth converting.

Let’s dive in.

Before making any decisions, assess your garage structure:

Most garages have thinner walls and cheaper materials than homes

Drafts and unsealed gaps can weaken soundproofing

Check if the structure is stable enough for added mass and modifications

This is your foundation,  knowing what you’re working with helps you avoid surprises later.

To truly stop sound from escaping your garage studio, you must follow these three principles:

Add weight to the walls using:

Extra layers of drywall

Heavier exterior siding

Mass-loaded materials

Stop vibrations from traveling through the structure by using:

Genie Clips + Hat Channels

A double-wall system

Floating ceilings

Even the smallest gaps leak sound. Seal:

Wall perimeters

Ceiling edges

Electrical penetrations

Garage door edges

Acoustic sealant is your best friend here.

If you want real soundproofing, the garage door needs special attention.

You have two choices:

This provides the best sound isolation. Fill it, frame it, and seal it.

This is more convenient but less effective.

Most high-quality studio builds choose Option 1 for results that actually work.

To stop sound, walls need to be heavy. Consider:

Adding new layers of interior drywall

Reinforcing exterior siding

Filling cavities before adding new mass

Using Genie Clips and Hat Channels is one of the most efficient ways to decouple walls and ceilings.

If your garage structure allows, a double-wall system gives the best performance, especially for loud instruments, drums, and full band recording.

Garage ceilings are tricky:

Many use truss systems, limiting modifications

Some ceilings cannot support heavy drywall

You may need a structural engineer if adding major mass

Don’t skip this check, ceilings are a common failure point in garage studios.

Use acoustic caulk to seal:

Wall corners

Perimeters

Ceiling junctions

Cracks and penetrations

Stopping air = stopping sound.

Here’s what to expect financially:

For basic upgrades, not full isolation.

This includes:
✔ Genie Clips
✔ Double drywall
✔ Garage door sealing
✔ Electrical upgrades
✔ HVAC system
✔ Professional labor

A garage studio is doable, just don’t underestimate the cost of real isolation.

Detached or semi-detached = less noise transfer

Existing structure saves money

Open floor plan gives design flexibility

No need to rent an external space

You’ll likely lose parking/storage

The garage door must be sealed or removed

You may need a dedicated HVAC system

Electrical upgrades may be required

HOA rules may restrict modifications

A garage may not be the right choice if:

Your budget is under $20,000

You must keep the garage door operational

HOA or city restrictions limit construction

You rely on the garage for storage

A garage studio is a great investment if:

It’s detached or semi-detached

It has a strong structure

You’re committed to full soundproofing

You want a permanent creative space

If you’re going all-in:

Seal and frame the garage door permanently

Assess ceiling load capacity

Use proper decoupling (Genie Clips / Hat Channel)

Install a controlled HVAC system

Upgrade your electrical if needed

Follow the principles of mass, decoupling, and airtightness

This ensures your studio is quiet, solid, and professional.
