Drywalling your garage is one of the best ways to improve its look, function, and value. Many homeowners want to know: what does it really cost to drywall a garage? The answer depends on the garage size, materials, labor, and other factors. Understanding these costs helps you plan your budget and avoid surprises.
If you’re new to drywall projects, you might feel confused about pricing, steps, or materials. This guide breaks down everything in simple English, with clear examples and numbers. Let’s explore the real cost to drywall a garage, so you can make smart decisions and get the most value from your investment.
What Is Drywall And Why Use It In Your Garage?
Drywall is a building material made from gypsum sandwiched between paper sheets. It’s used to cover walls and ceilings, replacing old wood or exposed studs. Most garages have unfinished walls when built, so adding drywall makes the space look clean and finished.
Benefits Of Drywall In A Garage
- Improved appearance: Makes your garage look like part of your home.
- Better insulation: Keeps the space warmer in winter, cooler in summer.
- Added fire protection: Drywall slows down fire spread.
- Easier repairs: You can patch holes or paint the walls as needed.
- Increased property value: Finished garages are more attractive to buyers.
Beginners often miss that drywall can help control moisture and noise too. It’s not just cosmetic—it makes the garage more comfortable and useful.
Average Cost To Drywall A Garage
Most homeowners spend between $1,500 and $4,000 to drywall a standard two-car garage. The total price depends on:
- Garage size (square feet)
- Drywall type and thickness
- Labor costs
- Extra features like insulation or painting
Here’s a real-world example:
- Single-car garage (12×20 feet, 240 sq ft wall area): $900–$1,400
- Two-car garage (20×20 feet, 400 sq ft wall area): $1,600–$2,800
- Three-car garage (30×20 feet, 600 sq ft wall area): $2,400–$3,800
These numbers include materials and labor. If you do the work yourself, you can save up to 50% of the cost.
Cost Breakdown Table
Below is a simple comparison of costs by garage size:
| Garage Size | Wall Area (sq ft) | Total Cost (Materials + Labor) |
|---|---|---|
| Single-car | 240 | $900–$1,400 |
| Two-car | 400 | $1,600–$2,800 |
| Three-car | 600 | $2,400–$3,800 |
Material Costs Explained
Drywall panels are sold by the sheet. A standard sheet is 4×8 feet and covers 32 square feet. You’ll also need joint tape, drywall mud, screws, and possibly insulation.
Typical Material Prices
- Drywall sheets (4×8 ft): $10–$20 each
- Joint compound (mud): $15–$25 per bucket
- Drywall tape: $3–$5 per roll
- Drywall screws: $6–$10 per box
- Insulation (optional): $0.40–$1.50 per sq ft
For a two-car garage (400 sq ft wall area), you might need:
- 13 drywall sheets ($130–$260)
- 2 buckets of joint compound ($30–$50)
- 2 rolls of tape ($6–$10)
- 1 box of screws ($6–$10)
Total Materials: $172–$330 (without Insulation)
Material Comparison Table
See how different drywall types affect cost:
| Drywall Type | Cost per Sheet | Best Use |
|---|---|---|
| Standard 1/2″ drywall | $10–$15 | Most garages |
| Fire-rated (Type X) | $15–$20 | Walls next to living space |
| Moisture-resistant | $16–$22 | Humid areas |
Fire-rated drywall is required by code for walls shared with the house. Moisture-resistant drywall is good for garages in wet climates.
Labor Costs: Diy Vs. Professional
Hiring a pro to install drywall costs $1.50–$3.50 per square foot for labor alone. This includes hanging, taping, mudding, and sanding.
- For a 400 sq ft area: $600–$1,400 labor cost
- For a 600 sq ft area: $900–$2,100 labor cost
If you install drywall yourself, you pay only for materials. But beginners often underestimate the time and effort. Drywalling a garage can take 2–5 days, depending on skill and garage size.
Pros And Cons
- DIY: Saves money, but needs tools and effort. Mistakes can lead to uneven walls.
- Professional: Costs more, but work is faster and looks better.
A common mistake is skipping the sanding step, which leaves visible joints. Pros use special tools for smooth results.
Extra Costs To Consider
Some garages need more than just drywall sheets. These extras can add to the cost:
- Insulation: Required in cold regions. Adds $100–$600.
- Painting: $1–$3 per sq ft, or $400–$1,200 for two-car garage.
- Electrical work: Moving outlets or switches can cost $100–$300.
- Permit fees: Some cities require permits, costing $50–$200.
If your garage has windows or unusual shapes, you’ll need extra material and labor. Most beginners miss these hidden costs.
Example: Complete Garage Upgrade
Let’s say you want to drywall a two-car garage, add insulation, and paint:
- Drywall materials: $250
- Insulation: $400
- Labor: $1,200

Total: $2,650
Planning for these extras avoids surprises and keeps your project on track.

- Screw sheets to studs
- Cut around windows, doors, and outlets
- Taping and mudding
- Cover joints with tape

How Garage Size Impacts Cost
Garage size is the main factor in drywall costs. Here’s how square footage changes the budget:
- Small single-car garage (10×18 ft, 180 sq ft wall area): $700–$1,200
- Large three-car garage (30×30 ft, 900 sq ft wall area): $3,800–$5,500
Measure your walls before buying materials. If you have extra corners, windows, or high ceilings, add 10–15% more material for waste and cuts.
Tips For Saving Money
Drywalling a garage doesn’t have to break the bank. Try these tips:
- Buy materials in bulk for discounts.
- Do some steps yourself, like painting or sanding.
- Get multiple quotes from professionals.
- Use standard drywall unless you need fire-rated or moisture-resistant types.
- Check local codes before starting—some garages require special drywall.
A non-obvious tip: consider recycling or reusing leftover drywall from other projects. This can cut costs and reduce waste.

Common Mistakes Beginners Make
Many first-time DIYers run into trouble with drywalling. Here are mistakes to avoid:
- Not measuring the garage accurately
- Buying the wrong drywall thickness
- Skipping insulation (if needed)
- Using too little joint compound
- Rushing sanding and finishing
- Forgetting permit requirements
Take your time, follow each step, and check local building codes. If you’re unsure, ask a pro or visit an expert site like Home Depot for advice.
Real-life Example: Drywall Cost For A 2-car Garage
Let’s look at a practical case. Mike wants to drywall his 20×20 ft two-car garage:
- Wall area: 400 sq ft
- Drywall sheets: 13 (4×8 ft)
- Materials: $220 (drywall, tape, mud, screws)
- Labor: $1,100 (professional install)
- Painting: $800
- Permit: $100
Mike’s Total: $2,220
If Mike did the work himself, he’d save the $1,100 labor cost, but it would take him a week and require tools.
Comparing Garage Drywall Costs To Other Rooms
Drywalling a garage is usually cheaper than finishing a basement or attic, but more expensive than a small bathroom.
| Room Type | Average Size (sq ft) | Total Drywall Cost |
|---|---|---|
| Garage (2-car) | 400 | $1,600–$2,800 |
| Basement | 600 | $2,400–$4,200 |
| Bathroom | 60 | $200–$400 |
| Living Room | 300 | $1,200–$1,800 |
Garages often require tougher drywall and more labor due to large wall areas and possible insulation.
