Kitchen Remodeling

A kitchen remodel should keep pace with a growing household, and that's especially true in a fast-growing city like O'Fallon. Promax Contracting plans layouts, cabinetry, countertops, and appliance placement around how your family actually uses the space, whether you want a fresh, modern kitchen or an update that fits an older O'Fallon home's original character. Reach out today to start planning your O'Fallon kitchen remodeling project.

Bathroom Remodeling

Bathroom remodeling requires careful coordination of plumbing, tile, fixtures, and layout, and it pays to work with a contractor who manages the entire process. Promax Contracting handles projects of every size for O'Fallon homeowners, from a simple fixture swap to a complete renovation, so the finished space holds up to daily use for years to come. We take the time to understand your goals and budget before work begins.

Basement Finishing

With so many O'Fallon homes built on full, unfinished basements, there's often significant living space waiting to be put to use. Promax Contracting handles basement remodeling and basement finishing projects that turn that space into a home theater, a playroom, a home office, or a place for extended family to stay. A finished basement adds usable square footage and can increase your home's resale value.

Deck Building

A well-built deck gives your family more room to spread out and enjoy O'Fallon's warmer months. Promax Contracting works with homeowners on every detail of a new deck, from size and layout to the right materials for Missouri's weather, so your outdoor space is built to last. Call (314) 770-0700 to talk with our team about your deck building project.
