Scrape Plumbers in Chicago from Google Maps into a mapped lead list

A big, fragmented local market

Plumbing is one of the largest local service trades in the United States, and demand tends to hold steady even when other sectors slow down. A metro the size of Chicago holds a dense, fragmented slice of that trade, and most of these businesses keep their public details, hours, and contact points on their Google Business Profile rather than in any tidy directory.

For anyone selling into that trade, whether you offer web design, marketing, insurance, supplies, or software, the list is the hard part. Chicago plumbers are scattered from Rogers Park to Beverly, many run lean operations, and their contact details live inside Google Maps rather than any tidy directory.

That is exactly the gap a browser capture fills. You already see the businesses on the map; you just need to get them out in a usable shape and into a place where you can sort, filter, and reach them.

From a Maps search to a working list

The process is simple and repeatable. Open Google Maps, run a search, and let the Vonsel Chrome extension read what is on screen. Like any well behaved Chrome extension, it works right in your browser, so each business you capture keeps its name, address, phone, website, category, and star rating.

Because Google limits a single search to roughly 120 results, one query for a citywide term will never return every plumber in Chicago. The fix is to search narrower and capture more often. A few practical searches for this market:

Run each search, capture the results, and repeat across the neighborhoods that matter to you. When you are done, the whole set lives in one place inside Vonsel. You can reopen an earlier capture and add more businesses to it later, so building the citywide list over a few sessions is normal, not a restart every time.

The list is the means, not the end

A plain export of Chicago plumbers is a starting point, not a sales asset. Most scrapers stop at the CSV and leave you to import it somewhere, clean it, and figure out who to call first. Vonsel treats the capture as step one of a workflow that ends in booked conversations.

Inside the Vonsel dashboard, every captured plumber lands on a map as a lead you can track. From there the intelligence layers turn raw fields into context you can sell on.

Cover the city without wasting effort

Chicago rewards a segmented approach. Rather than one messy citywide dump, build the list neighborhood by neighborhood and keyword by keyword, then merge. That keeps each capture under the result cap and gives you cleaner coverage of the North, West, and South sides.

De-duplication matters too. A plumber that ranks for both drain cleaning Chicago and emergency plumber Chicago will appear twice, so let the dashboard reconcile the same business across captures instead of emailing it twice. If you want the mechanics of a targeted pull, our guide on scraping plumbers from Google Maps walks through the niche end to end, and scraping Google Maps by location covers the geographic slicing in more depth.

Keep it clean and legal. You are capturing public business listings, not private personal data, but it still pays to understand the boundaries. See our overview of whether scraping Google Maps is legal before you run a large campaign.

Turn Chicago plumbers into conversations

Once your list is captured and cleaned, the fastest path to results is to prioritize and personalize. Sort the plumbers by rating and review volume, flag the ones missing a strong website or with recurring complaints, and start there.

Because Vonsel writes an AI email for each business, you can open a specific plumber, see the angle the dashboard suggests, and send in seconds. If you already run a pipeline elsewhere, you can also push captures into your own system: see moving Google Maps leads to a CRM.
