Key Drywall Cost Factors You Should Know
Drywall installation cost depends on several important factors. Each one plays a role in the final price you’ll see on your quote. Here’s a breakdown of the most common drywall cost factors:
1. Size and Scope of the Project
The larger the area you need to cover, the more materials and labor are required. For example, drywalling a small bathroom will cost less than finishing an entire basement. The square footage is the baseline for calculating costs.
2. Type and Quality of Drywall
Not all drywall sheets are created equal. Standard drywall is affordable and works well for most walls and ceilings. However, specialty drywall types like moisture-resistant, fire-rated, or soundproof panels cost more but offer added benefits. Choosing the right drywall for your needs affects the price.
3. Labor Costs and Complexity
Labor is a significant part of drywall installation expenses. Skilled professionals charge based on the complexity of the job. If your walls have many corners, arches, or unusual angles, expect higher labor costs. Also, finishing techniques like taping, mudding, and sanding add to the time and effort required.
4. Location and Accessibility
Where your property is located matters. In the St. Louis, St. Charles County, and St. Louis County areas, local market rates influence pricing. Additionally, if the installation area is hard to reach or requires special equipment, costs can increase.
5. Additional Materials and Supplies
Besides drywall sheets, you’ll need joint compound, tape, screws, corner beads, and sometimes insulation. These materials add to the overall cost but are essential for a professional finish.
6. Removal and Disposal of Old Drywall
If your project involves tearing down existing drywall, factor in demolition and disposal fees. Removing old materials safely and responsibly requires time and resources.
Understanding these drywall cost factors helps you anticipate expenses and communicate clearly with your contractor. It also allows you to prioritize what matters most for your project.

How much does it cost to drywall a 20x20 room?
Let’s get specific. Drywalling a 20x20 room is a common project size that many homeowners and property managers face. Here’s what you can expect in terms of cost and process.
Calculating the Surface Area
A 20x20 room has 4 walls, each 20 feet long. Assuming an 8-foot ceiling height, the total wall surface area is:
4 walls x 20 feet x 8 feet = 640 square feet
Add the ceiling area:
20 feet x 20 feet = 400 square feet
Total drywall area = 640 + 400 = 1,040 square feet
Material Costs
Standard drywall sheets typically measure 4x8 feet (32 square feet per sheet). You’ll need about 33 sheets (1,040 ÷ 32). At an average price of $12-$15 per sheet, materials alone can cost between $400 and $500.
Labor Costs
Labor rates vary, but in the St. Louis region, expect to pay between $1.50 and $3.00 per square foot for installation and finishing. For 1,040 square feet, that’s roughly $1,560 to $3,120.
Additional Expenses
Joint compound, tape, screws, and corner beads: $100-$200
Disposal of old drywall (if applicable): $100-$300
Specialty drywall or finishes: extra cost depending on choice
Total Estimated Cost
Adding it all up, drywalling a 20x20 room typically costs between $2,000 and $3,800. This range depends on the factors we discussed earlier.

Common Drywall Problems and How We Solve Them
Drywall installation isn’t always straightforward. Many homeowners and property managers encounter issues that can delay projects or increase costs. Here are some common problems and how FixPro addresses them:
Uneven Walls and Surfaces
Old homes or buildings often have uneven framing or surfaces. Installing drywall on these can lead to cracks or poor finishes. Our experts use leveling techniques and high-quality materials to ensure smooth, durable walls.
Moisture and Mold Concerns
In humid areas or bathrooms, moisture can damage drywall quickly. We recommend moisture-resistant drywall and proper sealing to prevent mold growth and maintain indoor air quality.
Cracks and Nail Pops
Over time, drywall can develop cracks or nail pops due to settling or temperature changes. FixPro uses advanced taping and finishing methods to minimize these issues and provide long-lasting results.
Delays and Scheduling Conflicts
We understand that timing is crucial. Our team works efficiently and communicates clearly to keep your project on schedule, minimizing disruptions.

Unexpected problems can increase costs. We provide detailed estimates upfront and keep you informed throughout the process to avoid surprises.
