Mold remediation companies in Missouri

St. Louis, MO / 4.8 rating from 5376 reviews / Water damage restoration service

Best for: St. Louis homeowners dealing with water damage that has led to mold growth, who want one company to handle plumbing repair, water extraction, and mold remediation under a single call.

Service area: Headquartered at 2671 Washington Ave in St. Louis, MO. Serves the St. Louis metro area including Oakville, University City, Webster Groves, Affton, Clayton, Crestwood, Richmond Heights, Ladue, Brentwood, Maplewood, and St. Charles. Claims coverage across 13 Missouri counties (including St. Louis, St. Charles, Jefferson, Franklin, Lincoln) and 10 Illinois counties (including St. Clair, Madison, Monroe). That is an extremely broad footprint -- confirm availability and response time for locations outside the immediate St. Louis urban core.

Review snapshot: Gabriel, Carl, and Nick draw consistent praise for thorough drain work and clear communication. But pricing complaints are a recurring theme, with multiple reviewers reporting quotes two to three times higher than competitors -- 14 one-star reviews across 5,376 total at 4.8 stars.

Chesterfield, MO / 4.9 rating from 2641 reviews / Water damage restoration service

Best for: Chesterfield and greater St. Louis homeowners dealing with water damage that has led to mold, who want plumbing repair and remediation handled by a single national franchise with 24/7 availability.

Also claims coverage into parts of Illinois including St. Clair and Madison counties. The claimed territory spans over two dozen counties across Missouri and Illinois, so response times at the edges of this area will likely be longer.

Review snapshot: Christian, Reggie, and Hasan draw consistent praise for clear communication and fast work, but pricing complaints run through both negative and 4-star reviews -- 9 one-star reviews across 2,641 total, several alleging unnecessary repair upsells.

St Charles, MO / 4.9 rating from 1785 reviews / Water damage restoration service

The claimed service area is broad, spanning roughly 25 counties across two states.

Review snapshot: Brian draws repeated praise for fast after-hours drain and plumbing work, and Tim gets called out for clear explanations. But pricing is the consistent complaint across 4-star reviews, and 2 one-star reviews out of 1,785 at 4.9★ cite billing pressure and a $100 quote fee.

Ozark, MO / 4.9 rating from 969 reviews / Water damage restoration service

Best for: Springfield and Ozark homeowners dealing with water damage that leads to mold, where 24/7 availability and a single company handling plumbing, water extraction, and remediation matters.

Service area: Based in Ozark, Missouri, with offices in Springfield. Serves the Springfield metro area across six counties: Greene, Christian, Lawrence, Newton, Webster, and Jasper. The core service area centers on Springfield and Ozark, with response times likely longer for outlying areas in the broader county coverage.

Review snapshot: Will Longino, Brady, and Riley draw repeated praise for fast, knowledgeable fieldwork across 969 reviews. But pricing is the consistent sore spot -- multiple reviewers describe quotes they found excessive, with 7 of 13 recent complaints about cost.

Grain Valley, MO / 5 rating from 724 reviews / Water damage restoration service

Best for: Kansas City homeowners dealing with mold after water damage who want a single company to handle extraction, drying, and remediation with direct insurance coordination.

Service area: 24 Hour Flood Pros' KC branch is headquartered in Grain Valley, Missouri. The website lists 19 cities served: Kansas City, Weston, Leavenworth, Platte City, Gladstone, Shawnee, Overland Park, Olathe, Liberty, Kearney, Excelsior Springs, Buckner, Raytown, Lee's Summit, Belton, Pleasant Hill, Richmond, Lexington, and Oak Grove. This covers a wide swath of the KC metro on both sides of the state line, plus some outlying towns — confirm response time for locations far from Grain Valley.

Review snapshot: Chris Watson draws the most praise across dozens of reviews for responsiveness and honest assessments. But with only 1 one-star review (no text) across 724 total, there is almost no negative signal to evaluate.

Springfield, MO / 4.8 rating from 665 reviews / Water damage restoration service

Best for: Springfield homeowners dealing with water damage that has led to mold growth, who want one crew to extract water, dry the structure, and handle remediation without coordinating multiple contractors.

Service area: Headquartered in Springfield, MO at 326 North Kansas Expressway. Serves Greene, Christian, Lawrence, Newton, Webster, and Jasper counties across the Springfield metro area. The six-county footprint is large for a single office, so response times outside Springfield and immediate Greene County surroundings will depend on technician availability.

Review snapshot: Will Longino draws the most praise across dozens of reviews for fast response, honest advice, and willingness to work crawl spaces and after-hours emergencies. But pricing complaints account for most of the 8 one-star reviews out of 665 total at 4.8 stars, with charges ranging from $285 for a washer repair to $11,000 for sewage work that reviewers considered unjustified.

Blue Springs, MO / 4.8 rating from 214 reviews / Water damage restoration service

Best for: Blue Springs and Lee's Summit homeowners dealing with water damage that has turned into a mold problem, backed by a two-location team known for fast emergency response.

Kansas City, MO / 5 rating from 193 reviews / Water damage restoration service

Best for: Kansas City metro homeowners dealing with water damage that has led to mold, where having one company handle extraction, structural drying, and remediation under one roof matters.

They serve the Kansas City metro on both sides of the state line, including Overland Park, Olathe, Shawnee, Leawood, Independence, Lee's Summit, Blue Springs, Liberty, Grandview, Belton, Raytown, and Topeka. The Des Moines office suggests Iowa coverage, though the website focuses primarily on Kansas City area content.

Review snapshot: Rod Bella draws the most praise across dozens of reviews for fast response and clear explanations, with PJ and Brett also frequently named. But one recent reviewer reported subcontracted restoration work with unfinished repairs and unreturned calls (1 one-star review across 193 total).

Best for: St. Louis and St. Charles County homeowners dealing with water damage that led to mold, who want a single company to handle mitigation, remediation, and full reconstruction under one insurance claim.

Service area: Property Medic is headquartered in Fenton, Missouri, with additional presence in St. Charles and Kirkwood. They serve St. Louis County, St. Charles County, and St. Clair County, Illinois. That is a wide geographic footprint across two states, so confirm availability and response times for locations outside the immediate Fenton area.

Named cities include North Kansas City, Liberty, Gladstone, Independence, Blue Springs, Lee's Summit, Overland Park, Olathe, Lenexa, and Lawrence. The claimed area extends to places like Warrensburg, Marshall, and Carrollton — 70+ miles from KC — so confirm response times for outlying locations.

Review snapshot: Jeremy, David, and Jason draw consistent praise for fast response and clear communication across 150 reviews. But one sewage cleanup customer reported incomplete work that led to mold growth, and the company never returned her calls — 2 one-star reviews across 150 total at 4.9 stars.

Review snapshot: Kylar Hernandez, Aden, and Noah draw consistent praise for communication and fast turnaround. But 2 one-star reviews across 128 total flag a $6,800 mold estimate one customer called gouging and a dispute with owner Dayton over demolition scope.
