Why Every Residential Builder Needs a Duplicate-Free Spreadsheet

Messy data steals profit. If your material price file or take-off schedule contains duplicate lines, CountBricks AI will still build an estimate, but the totals can balloon and margin forecasts get distorted. Knowing how to remove any duplicates in Excel is therefore a frontline skill for site managers, estimators and trade contractors who rely on CountBricks.com for instant pricing.

Duplicate Cells, Duplicate Costs

• A repeated line for 2 × 4 framing lumber can double your lumber allowance

• A twice-entered labor task can inflate man-hours and push back the project schedule

• Duplicate supplier SKUs can trigger purchase-order errors once the file is synced with CountBricks AI procurement tools

Before You Start: Back Up Your File

1. Open the Excel workbook that feeds your CountBricks price list.

2. Select File > Save As and append “_backup” to the file name.

3. Store the backup in your CountBricks cloud folder for quick retrieval.

Step-by-Step: How to Remove Any Duplicates in Excel

These steps apply to Microsoft 365 and Excel 2019 onward. Older versions follow the same flow, only menu labels differ slightly.

1. Highlight the full data range. A quick way is CTRL + A inside the data table.

2. On the ribbon, choose Data > Remove Duplicates.

3. In the dialog, tick only the columns that identify a unique line item. For most residential builders using CountBricks, that means:

• Item Code (SKU)

• Description

• Unit of Measure

4. Click OK. Excel reports how many duplicates were found and how many unique values remain.

5. Save the cleaned file and import or sync it with CountBricks.com/services for real-time estimating.

Pro Tips for Large Residential Price Files

• Sort before you dedupe. Sorting by Item Code clusters identical rows and makes visual review easier.

• Add a helper column. Concatenate Item Code & Description into a single field, then run Remove Duplicates on that helper to catch hidden variations such as extra spaces.

• Use Conditional Formatting > Highlight Cells > Duplicate Values to preview duplicates in red before committing to deletion.

• Remember that Excel treats uppercase and lowercase as identical in the Remove Duplicates tool, so SKU123 and sku123 count as one record.

Advanced: Power Query for Continuous Clean-Up

If your supplier sends weekly CSV price feeds, manually cleaning each file is tedious. Instead, use Power Query to automate:

1. Data > Get Data > From File > From Workbook, choose the incoming file.

2. In the Power Query Editor, select the identifying columns, then Home > Remove Rows > Remove Duplicates.

3. Close & Load. Each refresh will import the latest file minus duplicates. Map that refreshed table to CountBricks for hands-off updates.

How Clean Data Supercharges CountBricks AI

Once duplicates are gone, CountBricks can:

• Generate voice-driven estimates that pull each item only once, giving accurate subtotals

• Apply current supplier pricing without multiplying quantities erroneously

• Produce blueprint take-offs that align perfectly with your master price file, eliminating double counts

Case Snapshot: Sunshine Homes, Austin TX

Sunshine Homes migrated to CountBricks after discovering that a duplicated window line in their old spreadsheet overstated project costs by \$4,200. By following the duplicate-removal workflow above, they scrubbed a 3,200-line price book in under ten minutes. The immediate payoff:

• 90-minute reduction in weekly estimating time
