A garage looks straightforward until you realize every wall, seam, and ceiling span has its own story. Some are square, some aren’t, and moisture loves to sneak into the details.
That’s why drywall costs can feel all over the place.
Instead of guessing, it helps to understand what drives the number: size, materials, texture, and the condition of what’s already there. We’ll break all of that down so you can get a clear sense of what a garage really takes.
Key Notes
Garage drywall cost shifts with size, ceiling height, and material requirements.
Fast Patch garage projects typically fall into X-Large ($1,099+) or X-Large+ ($1,599+) package ranges.
Texture level and painting choices also significantly influence total pricing.

We price garage drywall work using the same clear package system we use for repairs.
Most garages land in X‑Large or X‑Large+ depending on size, ceilings, and add‑ons. If the scope is bigger or complex (vaulted ceilings, heavy electrical, moisture upgrades), we’ll do a quick in‑person consult.

How This Applies To Garages:
New or full‑surface garage drywall (walls + ceiling) typically maps to X‑Large or X‑Large+ as a base, then adjusts for material upgrades (moisture‑resistant, fire‑rated), ceiling height, and texture level.
If your garage only needs repairs before repainting, we’ll place you in the Small → Large+ tiers accordingly.
Garage Size & Layout Cost Breakdown
Garage sizes vary, and so does the amount of wall and ceiling surface we’re covering. Here’s how the math usually shakes out:
Single-Car Garage
Typical Size: ~240–350 sq ft
Estimated Cost: $2,000–$4,000+ depending on wall height and add-ons
Most Seattle single-car garages have lower ceilings and minimal electrical cutouts, so they tend to fall on the lower end of the range.
Older homes sometimes add surprises (uneven studs, moisture issues, mixed framing depths).
Two-Car Garage
Typical Size: ~400–550 sq ft
Estimated Cost: $4,000–$7,500+
More surface area means more seams, more corners, and more finishing work.
Many two-car garages also have laundry machines, water heaters, or breaker panels built into the space – all of which require cutouts and extra prep.
Three-Car & Oversized Garages
Typical Size: 600–900+ sq ft
Estimated Cost: $7,500–$12,000+
Large garages often come with:
Higher or vaulted ceilings
Multiple exterior walls
Long unbroken stretches of drywall
All of that adds labor time. Detached garages are especially prone to moisture, which can bump material choices into higher tiers.
Ceiling-Only Jobs
Estimated Cost: $1,200–$3,000+ depending on height
Ceilings are trickier than walls. They take more equipment, more labor, and more time. If the framing isn’t straight or if previous repairs exist, ceiling work can push costs up.
Material Choices That Change the Cost
Standard drywall works on most surfaces, but garages often need specialty boards depending on what the space connects to.
Standard Drywall (Baseline)
Your starting cost. Clean finish, quick install, strong enough for everyday use.
Moisture-Resistant Drywall
Seattle garages see their fair share of damp air, snow melt, and cold storage temperature swings.
Adds $0.50–$2.00 per sq ft
Helps prevent mold and swelling on exterior walls
Fire-Rated Drywall
Required by Seattle building codes when a garage wall connects to a living space.
$3.00–$6.00 per sq ft installed
Heavy, durable, and designed to slow fire spread
Soundproofing Options
Common for garages with bedrooms above them or shared walls.
Adds $2–$5 per sq ft
Acoustic panels cost $40–$60 each
These upgrades help reduce footstep noise, door slams, and vehicle rumble.
Insulation & Vapor Barriers
If your garage isn’t insulated, now is the time.
Batt insulation installation varies by garage size
Helps with temperature control and prevents condensation buildup behind drywall
Fast Patch’s Garage Drywall Process
We run garages like we run indoor repairs: clean, controlled, and efficient.
Step 1: Prep & Protection
We cover floors, tape off belongings, and set up dust control from the start. Even garages can get messy fast, so we prep like we’re indoors.
Step 2: Hanging Drywall
Panels are cut clean, hung level, and secured tight. Fire-rated boards go in where required by code.
Step 3: Taping & Hot Mud Application
Hot mud lets us:
Apply multiple coats in a single visit
Keep the job moving quickly
Reduce return visits
Step 4: Sanding & Texture
Our vacuum-assisted sanders keep dust to a minimum. We finish with whatever texture matches your preference or the existing surfaces.
Step 5: Painting (Optional)
Primer + paint applied evenly with crisp edges.
Step 6: Final Walkthrough
We log before-and-after photos, check for seam visibility, and make sure everything looks clean before we head out.
You’re covered by our one-year workmanship guarantee, so if anything settles or doesn’t look right, we return and fix it.

Frequently Asked Questions
Does my garage need permits for drywall installation in Seattle?
Most standard garage drywall installs don’t require a permit unless structural changes are involved. If you're adding fire-rated assemblies or modifying electrical lines, the city may require one. We’ll flag anything permit-worthy during quoting.
How long does it typically take to drywall a garage?
Most garages finish in a single day thanks to hot mud, unless the job includes major repairs, soundproofing, or upgraded materials. Ceilings over 10 feet or moisture damage can extend the timeline slightly.
Can you drywall a garage in winter or during rainy months?
Yes. As long as the space is dry and above minimum temperature thresholds for mud to cure, we can complete the job. If moisture is present, we address the source first so the finish lasts.
Do I need to empty my garage before the job starts?
Clearing the workspace helps us finish faster and keeps your belongings fully protected. If heavy items can’t be moved, we’ll cover and isolate them, but open floor space is ideal for clean results.

Conclusion
Drywalling a garage isn’t a quick guess or a one-size answer.
The realistic cost to drywall a garage in Seattle depends on size, ceiling height, and whether your walls need moisture-resistant or fire-rated boards. Most full-surface projects fall into the X-Large ($1,099+) or X-Large+ ($1,599+) range, with upgrades like soundproofing or smooth finish adding a bit more.
Painting, insulation, and the overall condition of the framing also move the final number.
