"We got 4 bids on our kitchen. Gateway Built wasn't the cheapest — but they were the only crew that gave us a 3D design before asking for a deposit. 8 weeks later we have our dream kitchen. Every contractor in STL should work this way."
"Finished my entire basement in 11 weeks. Project manager texted photos every single day. Only discovered one punch list item at final walkthrough — fixed within 48 hours. This is how every contractor should operate."
"Master bathroom went from original 1987 builder-grade to a full spa. The tile work alone is worth 5 stars. They found a slow leak behind the wall we didn't even know about — caught it before it became a disaster. Deeply grateful."
"Built us a two-level deck with screened porch and outdoor kitchen. My wife and I basically live out there now. All permits pulled, passed inspection first try. Already have them scheduled for a basement bar next spring."
"18-foot family room addition. The way it blends with the original house — you genuinely can't tell what's old and what's new. Their designer nailed it. Came in $1,200 under estimate. You don't find contractors like this."
"Whole-house gut renovation — kitchen, 3 baths, hardwood throughout, new HVAC. Lived in it for 22 years after. Every detail was exactly what we asked for. Doug and his crew are the real deal."
