Remodeling O'Fallon's suburban homes

O'Fallon grew from a small town to the region's most populous suburb in just a couple of decades, so most homes are 1990s-2010s builder-grade two-stories and ranches now hitting their first major remodel. Updating original kitchens and primary baths, finishing the (often unfinished) basement, and adding space as families grow are the projects that make the biggest difference here.

Neighborhoods we serve

We work throughout O'Fallon, including the WingHaven master-planned community and subdivisions near Fort Zumwalt Park and the city's parks and sports complexes.

Projects built for O'Fallon living

Kitchen and bath updates, basement finishing, outdoor living and additions are among our most common O'Fallon projects — modernizing boom-era homes without the cost of moving up.

Reviews From O'Fallon

Aptitude Design and Build just finished a 3rd project in our home! Since 2020 they have been welcomed into our home to build us the kitchen/laundry room of my dreams, the kid’s bathroom and just they finished a luxury primary bathroom/walk in closet. The team at Aptitude really wants to give you the remodel you want. They are very responsive to problems and solutions when hiccups/unexpected surprises come up. I highly recommend you give them the opportunity on your next project.

Aptitude Design & Build did a fantastic job on our kitchen renovation! They helped us achieve our vision and maintained excellent communication throughout. Right from the bidding process, they had ideas for optimizing our layout that other companies hadn’t thought of. The designer they assigned us listened to what aesthetic we were looking for and helped us choose cabinets and finishes that were within our budget. Aptitude had, by far, the best communication of any contractors we’ve worked with. Overall, we love our kitchen and are grateful for the work Aptitude did! We wouldn’t hesitate to use them again on another project.

I would definitely recommend Aptitude Design and Build for your remodel project. Communication is very important to Aptitude. Our project was a major kitchen remodel besides new paint, flooring and upgrades in electrical all through out our 40 year old house. The workers in our house were very respectful of our family and belongings. I cannot say enough about how happy we are with our old house with a new facelift!
