Drywall Estimates Common Mistakes to Avoid

Have you ever had a drywall project? Was it a DIY one or did professionals do it? Regardless if it was DIY or professionally done, you’ve surely done a drywall estimation. When embarking on a drywall project, whether you’re a homeowner or a contractor, getting an accurate estimate is crucial. An estimate that’s off the mark can lead to budget overruns, project delays, and a lot of unnecessary stress. Those are clearly the things we do not want to happen when we’re doing a drywall project. That is why, for this blog post, we’ll talk about exactly the things you should avoid when asking for or doing a drywall estimation. We’ll tell you the common mistakes in drywall estimates that you should avoid by helping you understand how drywall estimates work.

Understanding How Drywall Estimates Work

For those who are not familiar with how drywall estimates work, we’ll give you an easy to absorb step-by-step overview. It is very important to understand how this process works. By doing so, you are guaranteed to have a successful drywall project. Below is the step-by-step overview of how drywall estimation works:

Step-by-step Overview of How Drywall Estimation Works 

1. Measure the Space

  • The first step is to measure the area where the drywall will be installed. This includes measuring the height and width of each wall and ceiling.
  • For irregularly shaped rooms or those with unique features (like sloped ceilings or alcoves), more detailed measurements are required.

2. Calculate the Square Footage

  • Using the measurements, calculate the square footage of the walls and ceiling. This is done by multiplying the height by the width of each wall or ceiling area.

3. Determine the Number of Drywall Sheets Needed

  • Drywall typically comes in standard-size sheets (like 4×8 feet). Based on the square footage, calculate how many sheets are needed.
  • Include extra sheets (usually around 10% more) to account for waste and cuts.

4. Estimate Additional Materials

  • Apart from drywall sheets, other materials such as joint compound (mud), tape, screws, and corner beads are required. The amount of these materials depends on the project size.

5. Factor in Labor Costs

  • Labor costs can vary widely depending on the complexity of the job, the geographic location, and the contractor’s rates.
  • Complex tasks like installing drywall on high ceilings or working around numerous windows and doors can increase labor costs.

6. Include Special Requirements

  • If the project requires special types of drywall, like moisture-resistant or fire-rated, this will affect the cost.
  • Soundproofing or other specialized treatments also add to the expense.

7. Account for Preparation and Cleanup

  • Preparation work (like removing old wall coverings) and post-job cleanup should be considered in the estimate.

8. Consider Overheads and Profit Margins

  • Contractors will include overheads (like transportation, equipment use, etc.) and a profit margin in their estimates.

9. Add a Contingency Budget

  • A contingency (around 10-20% of the total estimate) is often added to cover unexpected costs or issues that may arise during the project.

Top 5 Common Mistakes in Drywall Estimates to Avoid 

Now that it’s clear to you how drywall estimates work, avoiding the common mistakes is now easy peasy lemon squeezy! Hence, here are the five common mistakes in drywall estimates that you should avoid:

1. Underestimating the Material Costs

One of the most common errors in drywall estimates is underestimating the cost of materials. Drywall sheets, joint compound, tape, screws, and other materials can vary significantly in price based on quality and quantity. It’s essential to do thorough research or consult with suppliers to get an accurate cost estimate. Remember, cheaper materials might save money upfront but can lead to higher costs in repairs and maintenance down the line.

2. Overlooking Additional Expenses

Drywall projects often involve more than just hanging sheets. Additional expenses like transportation, waste disposal, and even the cost of protective gear can add up. It’s important to factor in these ancillary costs when creating an estimate. Neglecting to do so can lead to a budget that falls short of actual needs.

3. Miscalculating Labor Costs

Labor costs can be tricky to estimate, especially for those who are new to drywall projects. It’s not just about the hours put into hanging the drywall; it also includes preparation time, cleanup, and potential overtime. Understanding the scope of the project and the labor required is crucial. It’s advisable to consult with experienced professionals to get a realistic view of labor costs.

4. Ignoring Project Complexity

Every drywall project is unique. Factors like wall height, room shape, and the presence of windows or doors can complicate a job. These complexities require additional time and materials, impacting the overall cost. An accurate estimate takes into account these complexities rather than applying a one-size-fits-all approach.

5. Failing to Plan for Contingencies

No matter how well you plan, unforeseen issues can arise. It could be anything from discovering mold behind an old wall to needing extra material after a measurement mistake. A smart estimate includes a contingency budget, typically 10-20% of the total estimate, to cover these unexpected costs.


Accurate drywall estimates are a balancing act of precise calculation and informed forecasting. By avoiding these common mistakes, you can ensure that your drywall project starts off on the right foot. Remember, it’s always better to be over-prepared than underfunded. With careful planning and attention to detail, your drywall project can be completed smoothly and within budget.
