So, you’re thinking about turning your garage into a studio? 🎶 On the surface, it sounds simple: throw up some drywall, maybe add carpet, and you’re good to go, right? Well… not exactly. Soundproofing a garage is one of the trickiest projects out there. If you don’t plan carefully, you’ll end up with a space that leaks sound, overheats, or feels like a box you can’t breathe in.
But don’t worry, I’ll walk you through the key steps and common mistakes so you can set your project up for success.
1. Decoupling the Walls
One of the biggest mistakes people make is attaching new drywall directly to the existing studs. That creates a direct path for sound to travel straight through the walls.
The solution? Decoupling.
-
Best option: Build a double wall system. That means two sets of studs with at least an inch of space between them. Think of it like building a “room within a room.”
-
Alternative option: Use acoustic clips (like Genie Clip RSTs) and hat channel. These keep the drywall floating, instead of tied directly to the studs. Add two layers of 5/8” drywall to make it effective.
This step is the foundation of your soundproofing. Skip it, and you’ll regret it later.
2. What to Do With the Garage Door
Ah yes, the classic garage door dilemma. Leaving it as-is is like trying to block water with a paper towel—it just won’t work.
-
Best solution: Remove the garage door entirely and finish the front wall with siding so it blends with your house.
-
If you can’t remove it: Keep the garage door as a façade, but build a proper wall behind it for real sound isolation.
3. Picking the Right Doors
This is where a lot of DIY studios fail. Hollow core doors might look fine, but they won’t stop sound. They simply don’t have the mass.
Instead, choose solid-core studio doors or something specifically made for sound isolation. (If you want a shortcut, the ISO Store has excellent options.)
4. Planning the HVAC System
You can build the most airtight, soundproof box in the world—but if you can’t breathe in it, you won’t want to spend time there.
Here’s the catch:
-
Mini-split systems only recirculate air; they don’t bring in fresh air.
-
You’ll need a dedicated ventilation system that pulls in fresh air and pushes out stale air.
-
To keep sound from leaking, run your ducts through baffle boxes that absorb noise before it escapes.
Proper HVAC planning is what separates a professional studio from a sweaty, stuffy garage box.
5. Common Pitfalls to Avoid
-
Using only one layer of drywall (not enough mass).
-
Forgetting to seal or treat vents.
-
Installing cheap hollow doors.
-
Skipping the planning stage and just “winging it.”
6. Plan First, Build Second
Soundproofing a garage isn’t about buying the most expensive materials—it’s about using the right methods. Take the time to draw up your plan, list out the materials, and understand the science behind each choice.
If you get it right the first time, you’ll save yourself a ton of money, stress, and rework later.
