Remodeling contractor in O'Fallon, MO

The county's largest city and most of its newer subdivisions. Basement finishes, deck replacements and primary-bath remodels are the common calls.

O'Fallon is the largest city in the county and the one with the widest range of housing: 1990s subdivisions south of Highway 70, large 2000s developments around WingHaven and along Highway K, and newer builds still going up on the west side.

That range shows in what we do here. Newer homes get their basements finished and their builder-grade baths upgraded. The 1990s stock gets kitchens opened up and decks replaced. The larger lots on the edges get additions and outbuildings.

Questions O'Fallon homeowners ask

Do you take jobs in O'Fallon?

Yes. O'Fallon is about 12 minutes from our office on State Route N in Cottleville, well inside the area we work every week.

Who pulls the permit for a remodel in O'Fallon?

We do. O'Fallon issues its own building permits through the city's Planning and Development division. We submit the application, schedule each inspection and meet the inspector on site.

Do you charge for the first visit?

No. The walkthrough and the written quote are free. You only pay once you sign a contract and work is scheduled.

How soon can you start?

It depends on the season and the size of the job. Small projects such as a staircase or a deck can often start within a few weeks; kitchens and basements are scheduled once cabinets or materials are confirmed. We give you a real date, not a guess.

Who does the electrical on your jobs?

First Choice Electric, a licensed electrical contractor based minutes from our shop. When the job needs wiring, we bring them in and coordinate the schedule.

Are you licensed and insured?

We are insured, and we handle the permits on every job that needs one. Missouri has no statewide general contractor licence; a few cities license contractors, and we follow each city's rules. Ask and we will send the certificate of insurance.

Can I see work you have done near O'Fallon?

Yes. The project gallery on this site is all our own jobs, and we can point you to a nearby one that matches what you have in mind.

Sean and John came in and turned my abysmal bathroom into something amazing. Great service, professional, timely and excellent at communicating. They will be back to do many other projects for me.

Sean, from SC2 contracting just finished building my new deck. I couldn't be more pleased! Not only did Sean do a great job, but he made the project very pleasant by always communicating when he'd be at my house, if it was okay to work on weekends, and what was happening next. He clearly is a man of high integrity, taking pride in doing a good job and working hard every day to get the job done(even in the St Louis heat we had this summer).

I will definitely be in touch with him again to do other projects for me, and have no doubt I'll get the same wonderful results!!
