Mold remediation companies in Illinois

Rockford, IL / 4.8 rating from 4823 reviews / Water damage restoration service

Best for: Rockford-area homeowners dealing with water damage from burst pipes or basement flooding who want one company to handle both the plumbing repair and the cleanup in a single visit.

Service area: Headquartered in Rockford, Illinois at 5291 28th Ave. Serves Winnebago, Stephenson, and Boone counties, including Belvidere, Freeport, Loves Park, Machesney Park, Roscoe, Cherry Valley, South Beloit, and Rockton. The franchise lists over 30 cities across the three-county metro area.

Review snapshot: Bailey, Daniel, and Mackenzie draw consistent praise for clear explanations and fast work. But 26 negative reviews across 4,823 total at 4.8 stars reveal a pattern of aggressive upselling on sewer line repairs, with multiple customers reporting second opinions that found no damage.

Belleville, IL / 4.8 rating from 2862 reviews / Water damage restoration service

Best for: Belleville and metro-east Illinois homeowners dealing with water damage that has led to mold growth, who want one company to handle both the plumbing source fix and the remediation.

Service area: Headquartered in Belleville, IL at 110 W Main St. Serves the entire St. Louis metro area across both Illinois and Missouri, including Saint Clair, Madison, and Monroe counties in Illinois, plus Saint Louis, Saint Charles, and Jefferson counties in Missouri — 23 counties total. That is a very large territory for one office; confirm dispatch times for locations far from Belleville.

Review snapshot: Bob and Connor draw consistent praise for fast, friendly drain and plumbing work across dozens of recent reviews. But pricing complaints recur — 5 of 13 recent negatives cite costs they found excessive — anchored against 2,862 total reviews at 4.8 stars.

Aurora, IL / 4.8 rating from 2083 reviews / Water damage restoration service

Best for: Aurora and western Chicago suburbs homeowners who need same-day water damage response with mold remediation handled by the same crew, especially when a plumbing failure caused the water intrusion.

Service area: Based in Aurora, IL at 1691 Town Center St, Suite 104. Claims coverage across 12 counties in three states: McHenry, DuPage, Cook, Lake, Grundy, Will, Kane, DeKalb, and Kendall counties in Illinois; Lake and Porter counties in Indiana; and Walworth, Racine, and Kenosha counties in Wisconsin. That is the entire Chicago metro area and then some. Confirm actual dispatch time for locations outside Kane and DuPage counties.

Review snapshot: Eddie, Tim, and Marc draw repeated praise for same-day arrivals and clear explanations. But pricing is the dominant complaint, with 11 of 13 recent negatives citing costs two to six times higher than competitors across 2,083 total reviews at 4.8 stars.

Elmhurst, IL / 4.8 rating from 2030 reviews / Water damage restoration service

Best for: West suburban Chicago homeowners dealing with water damage and secondary mold who want a single company to handle mitigation, remediation, and reconstruction under one insurance claim.

Service area: Headquartered in Elmhurst, Illinois. Serves the Chicago metropolitan area including Chicago proper and suburbs across Cook, DuPage, Lake, Will, Kane, McHenry, and Kendall counties. Lists over 130 specific Illinois cities from Zion to Joliet. Also claims coverage in southern Wisconsin and northwestern Indiana, though the breadth of that three-state claim from a single Elmhurst office warrants confirming response times for locations outside the core suburban ring.

Review snapshot: Xavier, Shondell, and Giovanni draw consistent praise for fast on-site response and clear explanations. But 27 negatives across 2,030 reviews at 4.8 stars center on poor communication from project managers and billing disputes after initial mitigation.

Elk Grove Village, IL / 5 rating from 698 reviews / Water damage restoration service

Best for: Chicago-area homeowners dealing with water emergencies who want same-day response and a single company to handle mitigation through reconstruction, including insurance coordination.

Service area: Headquartered in Elk Grove Village, Illinois. Serves the greater Chicago area. Reviews confirm jobs in suburban Cook County, Fox Lake (Lake County), Des Plaines, and at least one project in Wisconsin. The service radius extends well beyond the immediate Chicago metro, though response times and pricing may vary outside the core area.

Review snapshot: Justin, Kevin Lin, and Noah draw consistent praise for fast response and clear communication, but 7 complaints across 698 reviews at 5.0 stars flag project manager ghosting and a reconstruction quote that tripled after mitigation began.

Addison, IL / 4.8 rating from 626 reviews / Water damage restoration service

Best for: Chicagoland homeowners dealing with water damage or mold after a flood or leak who need same-day emergency response and in-house reconstruction from a single contractor based in Addison.

Service area: Headquartered in Addison, Illinois, with a second office in Chicago at 159 N Sangamon St. Romexterra claims to service the entire Chicagoland area. Their website names specific service cities including Chicago, Addison, Naperville, Elk Grove Village, Highland Park, Skokie, Elmhurst, Aurora, Plainfield, Winnetka, and Deerfield. Reviews confirm jobs in Aurora, Bartlett, and Lisle, suggesting genuine reach across DuPage, Cook, and western suburban counties.

Review snapshot: Jackie Hersam, Sammy Cruz, and Victor G draw consistent praise for responsiveness and care, but billing disputes and invoices far exceeding verbal quotes account for most of the 11 one-star reviews across 626 total at 4.8 stars.

Lake Zurich, IL / 4.8 rating from 605 reviews / Water damage restoration service

Best for: Chicago-area homeowners and realtors dealing with mold or persistent odors who want a chemical-free ozone treatment with a written guarantee and same-day or next-day scheduling.

Serves the greater Chicago area including Naperville, Schaumburg, Evanston, Palatine, Barrington, Aurora, Elmhurst, Skokie, Wheaton, Des Plaines, Rockford, and surrounding suburbs. Also operates in Indiana, Wisconsin, Texas, Florida, Pennsylvania, New Jersey, and Louisiana — confirm local crew availability for locations outside the Chicago metro.

Review snapshot: Mike, Marco, and Cody draw consistent praise for clear explanations and same-day availability across 605 reviews. But 3 of 6 recent complaints involve deposit refund disputes or finishing quality on restoration work, with 3 one-star reviews out of 605 total.

Wood Dale, IL / 4.9 rating from 542 reviews / Water damage restoration service

Best for: Chicagoland suburban homeowners in DuPage or Cook County who need water damage cleanup and mold removal handled by the same NADCA-member crew with 24/7 emergency response.

Service area: Headquartered in Wood Dale, Illinois. They claim coverage across six counties: DuPage, Cook, Lake, Will, Kane, and McHenry. Their service area page lists over 130 specific cities and towns across Chicagoland. This is a broad footprint radiating outward from their DuPage County base, and response times to the outer edges of Lake, McHenry, and Will counties are worth confirming.

Review snapshot: Allan, David, and Drey draw consistent praise for explaining each step with before-and-after photos. But 3 one-star reviews across 542 total flag on-site price increases and an unanswered web inquiry.

Waukegan, IL / 5 rating from 381 reviews / Water damage restoration service

Best for: Waukegan and Lake County homeowners dealing with water damage or mold who want a single contractor to handle mitigation through full reconstruction.

Service area: Headquartered in Waukegan, IL. Serves Lake County IL including North Chicago, Zion, Beach Park, Winthrop Harbor, and Great Lakes. Also covers Kenosha County WI (Kenosha, Pleasant Prairie, Bristol, Salem Lakes) and parts of Racine County WI (Woodworth). One reviewer reported using them for a job in St. Charles, IL, about 50 miles southwest of Waukegan.

Review snapshot: Leo draws the most praise for personal responsiveness, with Miguel, James, and JJ also named repeatedly for fast, hands-on work. But with only 3 sub-4-star reviews across 381 total, there is not enough negative data to identify any complaint pattern.

Bloomington, IL / 4.9 rating from 365 reviews / Water damage restoration service

Best for: Bloomington-Normal homeowners dealing with mold after water damage who want one company to handle testing, remediation, crawl space encapsulation, and insurance paperwork within a 40-mile radius.

Reviews confirm work in Towanda and across the Bloomington-Normal metro. The Champaign and Peoria reach pushes the edges of that radius.

Review snapshot: Caleb, Zach, and Harley draw repeat praise for fast scheduling and walking homeowners through the process. But communication drops off after the initial job: 7 complaints across 365 reviews at 4.9 stars, with delayed quotes, missed follow-ups, and scheduling problems surfacing most often.

Marion, IL / 5 rating from 328 reviews / Water damage restoration service

Best for: Southern Illinois homeowners in Jefferson, Franklin, or Perry Counties dealing with water damage or mold after basement flooding, backed by a family-owned SERVPRO franchise with a 5.0-star rating across 328 reviews.

Vernon and Benton as service areas, and reviews confirm work in Carbondale, Murphysboro, DuQuoin, Pinckneyville, West Frankfort, and Sesser. This is a broad rural territory spanning much of Southern Illinois.

Review snapshot: Erica Blackford draws heavy praise across dozens of reviews for customer service, and Josh and Dakota are singled out for hands-on crew leadership. But 1 reviewer out of 328 total at 5.0 stars reported property damage during service.

Downers Grove, IL / 4.9 rating from 308 reviews / Water damage restoration service

Best for: Downers Grove homeowners and businesses dealing with mold after water damage who want a single restoration company to handle demo, remediation, and rebuild under one roof.

As a franchise location, their territory has defined boundaries — confirm coverage for addresses outside those named cities.

Review snapshot: CJ, John Santiago, and Damian Guerrero draw consistent praise for fast response and clear communication, but 2 of 308 reviews flag estimate fees and subcontractor accountability gaps on rebuild work.
