Accurate estimating plays a crucial role in construction and insurance restoration projects. Among the most popular tools for estimating is Xactimate, a software widely used by contractors, adjusters, and estimators to create detailed project estimates. However, even though Xactimate is powerful, mistakes in using it can lead to serious problems — such as underbidding, overcharging, project delays, or disputes between contractors and clients.
At Prime Estimation, we specialize in creating accurate, data-driven Xactimate estimates that prevent these common pitfalls. In this article, we will discuss the most frequent mistakes made in Xactimate estimates and explain how our professional services avoid them to ensure your project runs smoothly, efficiently, and profitably.
1. Incomplete Scope of Work
One of the most common errors in Xactimate estimates is failing to include the full scope of work. Many estimators overlook certain tasks, materials, or equipment that should be part of the project cost. This often happens when estimators rush through the inspection or fail to gather complete information on-site.
For example, an estimator might forget to include tear-out and disposal costs, labor setup, or material waste factors. These missing items can lead to inaccurate estimates and, later, to disputes when the contractor requests change orders.
How We Avoid It
At Prime Estimation, we use a systematic approach to capture every detail of the scope. Our team reviews the project thoroughly — from initial site inspection data to plans, photos, and notes — to ensure no line item is missed. We also follow industry checklists and insurance standards to guarantee completeness. Every Xactimate estimate we produce includes all required materials, labor, and overhead costs, ensuring you never leave money on the table.
2. Incorrect Line Item Selection
Xactimate has thousands of line items, and selecting the wrong one is a frequent mistake. A minor difference between two similar items can lead to a major cost variation. For example, using the wrong category for a drywall repair or incorrect unit of measurement can result in hundreds of dollars of loss or overestimation.
How We Avoid It
Our team consists of certified Xactimate professionals who understand the software inside out. We know how to select precise line items that match the work performed. Before finalizing, we cross-check all line items with the project’s actual scope and regional cost data. This ensures that your estimates are accurate, consistent, and defensible in front of clients or insurance adjusters.
3. Ignoring Regional Pricing Updates
Xactimate updates its pricing database monthly to reflect current market rates for labor and materials. Many users make the mistake of using outdated price lists, leading to inaccurate estimates that don’t reflect current conditions. This issue becomes critical during periods of inflation or material shortages.
How We Avoid It
We always ensure that our estimates use the latest Xactimate pricing database. Our team checks for regional updates before starting each estimate to reflect local labor and material costs accurately. By keeping up with real-time pricing, we make sure your bids are competitive and profitable, avoiding underpricing that can hurt your margins.
4. Failing to Include Overhead and Profit (O&P)
Many inexperienced estimators forget to include overhead and profit, especially in insurance claims where the software doesn’t automatically apply them. Missing O&P can reduce total compensation by up to 20%, significantly affecting profitability.
How We Avoid It
At Prime Estimation, we always ensure that O&P is correctly applied based on the project type, scope, and complexity. Whether the project involves general contracting, restoration, or specialty trades, we make sure your estimate includes justified overhead and profit to represent your true business costs.
5. Inaccurate Labor Productivity or Waste Calculations
Labor productivity and waste factors can vary greatly depending on job complexity, site conditions, and materials used. Using default or incorrect values in Xactimate can distort the real cost. For instance, failing to adjust waste percentages for complex roof shapes or multi-layer flooring can lead to underestimation.
How We Avoid It
We base our labor and waste calculations on real-world data and industry standards. Our estimators adjust productivity rates according to project conditions such as height, accessibility, and job difficulty. This approach ensures that every estimate reflects actual field conditions, not just software defaults.
6. Missing Supporting Documentation
Another major issue is submitting estimates without sufficient supporting documents — such as photos, sketches, or notes. This often causes delays in claim approval or payment processing since reviewers lack evidence for specific line items.
How We Avoid It
Our estimates always come with comprehensive documentation, including detailed sketches, damage photos, and notes explaining why certain items are included. This transparency builds trust and speeds up approval. Our clients rarely face disputes because our documentation makes every estimate clear, complete, and verifiable.
7. Not Accounting for Code Upgrades or Permit Fees
Estimators often forget to include building code upgrades or permit fees required by local regulations. Missing these items can cause significant financial loss or project delays when the work must be redone to meet code requirements.
How We Avoid It
We research local code requirements and include applicable upgrades in the estimate. Whether it’s fire-resistant materials, energy-efficient systems, or accessibility features, we ensure full compliance. Our team also factors in permit and inspection fees to create truly complete and realistic estimates.
8. Poor Communication Between Adjusters and Contractors
Sometimes, even when estimates are technically correct, poor communication between adjusters, contractors, and estimators leads to misunderstandings. This can result in rejected estimates or delays in claim settlements.
How We Avoid It
At Prime Estimation, we act as a bridge between contractors and adjusters. Our team communicates clearly, provides detailed notes, and quickly revises estimates if required. This ensures smoother collaboration and faster approvals, helping clients complete their projects without unnecessary delays.
9. Overlooking Depreciation and Policy Details
In insurance restoration projects, failing to apply the correct depreciation values or misunderstanding policy coverage terms can cause payment discrepancies. Estimators might miscalculate the recoverable depreciation or misinterpret replacement cost vs. actual cash value policies.
How We Avoid It
Our team understands insurance policy structures and always applies the correct depreciation rates. We double-check claim documents and ensure that the estimate aligns perfectly with policy terms. This precision minimizes disputes and ensures full compensation for your work.
10. Lack of Quality Review Before Submission
Finally, many estimators fail to review their work thoroughly before submission. A simple typo, wrong measurement, or missing section can undermine the accuracy of an entire estimate.
How We Avoid It
Every Xactimate estimate we prepare goes through a multi-step quality assurance process. A senior estimator reviews each estimate for accuracy, consistency, and completeness before it’s delivered to the client. This final check guarantees that our estimates are not only precise but also ready for immediate use.
Conclusion
Xactimate is an excellent estimating tool, but it requires expertise and attention to detail. Small mistakes can lead to big financial consequences, project delays, or claim disputes. That’s why partnering with professionals who understand both construction practices and Xactimate software is essential.
At Prime Estimation, we help contractors, adjusters, and restoration professionals save time, reduce stress, and maximize profit through accurate, reliable, and fully documented Xactimate estimates. Our deep understanding of the software and field conditions ensures your estimates are always correct, defensible, and compliant.
