What homeowners say
after a Gateway job.

Webster Groves · Sewer backup

“They tested before they tore out.”

“Our basement backed up overnight. Three companies came out. Two of them quoted to gut the entire finished basement. Gateway tested, found the contamination only ran four feet up the wall, and saved us about $40K in scope. Insurance approved their file in eight days.”

Chesterfield · Burst supply line

“They actually answered the phone at 3am.”

“Pipe burst on the second floor at 2:30 in the morning. I called four numbers. Gateway picked up live, dispatched a crew, and they were in my driveway in 70 minutes. By 6am they had the water out and equipment running. Genuinely don’t know what we’d have done without them.”

Belleville · Mold inspection

“They told us we didn’t need remediation.”

“Bought a 1920s home, the inspector said get a mold test. Gateway came out, sampled, and the lab came back showing the staining was cosmetic, not active mold. They wrote a clear report we used at closing. Total bill: under $500. Three other companies had quoted thousands for remediation.”

Florissant · Storm flood

“Eight homes on our block, they got to all of us.”

“After the August storm, half the basements on our street were flooded. Gateway sent multiple crews and worked our whole block. They were honest about the ETA during the surge, said three hours, showed up in three hours. Insurance file was clean and our claim approved in two weeks.”

Clayton · Mold remediation

“The clearance test mattered.”

“After remediation, they did an independent clearance air-quality test before taking down containment. Other companies skipped that step. When we sold the house six months later, having documented clearance results was a real asset on the disclosure.”

Edwardsville, IL · Sump failure

“They wrote the file the way our carrier wanted.”

“Sump pump failed during a power outage and the basement flooded six inches deep. Gateway documented everything Xactimate-style. Our adjuster told us, on the phone, that this was the cleanest mitigation file he’d seen all year. Approved on first review.”
