Remove Duplicates from Home Services Provider Data
✓ TestedWorks with CSV, Excel, Google Sheets → JSON-LD Schema

Home services directories and lead generation platforms aggregate provider data from multiple sources: contractor registrations, Google Business profiles, Yelp listings, and manual submissions. The same plumber or electrician frequently appears multiple times with different phone numbers, slight address variations, or abbreviated business names. dataclean.to detects these overlapping provider records so your directory shows one accurate listing per business.
The Problem
Home services data suffers from duplication because contractors often operate under multiple names, serve overlapping service areas, and list themselves on every platform available. 'Bob's Plumbing LLC' might also appear as 'Bob Smith Plumbing' and 'Robert Smith - Licensed Plumber' across different sources. Address inconsistencies add confusion when a sole proprietor lists both a home address and a PO box. These duplicates inflate directory counts, confuse homeowners comparing providers, and split reviews across multiple profiles for the same contractor. FTC guidance on consumer reviews for businesses
How to Fix It
1
Export provider listings
Export your home services directory or CRM data to CSV. Include business name, owner name, phone number, email, address, license number, and service categories for each provider.
2
Upload to dataclean.to
Upload the CSV. The tool analyzes business names, phone numbers, and addresses to identify providers listed multiple times under different names or contact details.
3
Review flagged duplicates
Examine each duplicate cluster. Look for patterns like abbreviated vs. full business names, different phone numbers for the same address, or the same license number appearing on multiple records.
4
Merge provider records
Consolidate duplicates into a single listing per provider. Retain the most complete contact information, the highest review count, and the current license status from across all duplicate entries.
5
Export and update your directory
Download the clean CSV and update your directory or CRM. Each provider now has one definitive listing with accurate contact details and consolidated service area coverage.
Frequently Asked Questions
How does the tool handle contractors with multiple locations?
Multi-location contractors are flagged for review but not automatically merged. If two records share the same business name and license number but different addresses, the tool presents them as potential duplicates so you can decide whether they represent separate branches or a true duplicate.
Can it match providers across different data sources?
Yes. Combine exports from your directory, Google Business scrapes, and CRM into one upload. The tool compares all records together, catching cross-source duplicates that differ in formatting or completeness.
What if a provider changed their business name?
Name changes are common in home services when contractors rebrand or incorporate. The tool matches on phone number, address, and license number in addition to business name, so renamed businesses are still detected as duplicates of their previous listing.
