Our Basement Finishing Services

Every lower level is different, so we start by understanding how you live and what you want this space to do for you. Then we design and build a finished basement that fits your home, lifestyle, and budget.

Basement Bathrooms

Add a full bathroom, powder room, or guest bath so your new living space is truly comfortable and convenient. We design bathrooms that work with existing plumbing where possible, plan smart layouts, and use durable materials that hold up to everyday use.

Bars, Kitchens & Entertaining Spaces

From a simple wet bar to a full lower-level kitchen, we create gathering spaces that make it easy to host. Think beverage centers, built-in storage for glassware, under-cabinet lighting, and layouts that keep everyone connected while you cook, serve, and entertain.

Guest Suites & Bedrooms

Give guests a quiet, private place to stay with dedicated bedrooms or full guest suites in your finished basement. We plan proper egress, natural and artificial lighting, and storage so the space feels like a true extension of your home—not a spare room.

Home Theaters, Game Rooms & Media Rooms

Want a movie-night space, kids’ hangout, or game room? We handle layout, lighting, sound, and wiring so your theater or media room performs as good as it looks. Built-ins, wall niches, and smart storage keep cords, consoles, and clutter under control.

Home Offices, Gyms & Flex Spaces

Need a quiet place to work from home, a dedicated workout area, or a flexible play space? We design multi-use rooms that can adapt over time—adding doors, storage, and lighting plans that let the space evolve as your needs change.

Still confused which basement type you need that suits your lifestyle?

How Much Does It Cost to Finish a Basement in St Louis?

Every basement is different, but most full basement finishing projects in the Greater St. Louis area land in a broad range. The final cost depends on square footage, how much structural work is needed, and the type of rooms you want to add.

In general, pricing is shaped by four main factors:

• Size of the basement – Larger basements require more framing, drywall, flooring, and finishes.

• Number of rooms and walls – Open-concept spaces are typically less expensive than layouts with multiple bedrooms, offices, or media rooms.

• Plumbing-heavy spaces – Adding bathrooms, a bar, or a kitchenette increases both labor and material costs.

• Level of finishes – Flooring, cabinetry, countertops, trim details, and lighting can move the project toward the lower or higher end of the range.

During your free in-home estimate, we walk the space, discuss how you’d like to use it, and provide a realistic price range tailored to your basement—no generic guesswork.

What Is the Most Expensive Part of Finishing a Basement?

For most St. Louis homeowners, the costliest parts of a basement finishing project are:

• Bathrooms and plumbing work – Running new supply and drain lines, adding a shower, tub, or multiple fixtures, and tying into existing plumbing can be a significant portion of the budget.

• Kitchenettes, wet bars, and built-ins – Cabinetry, countertops, appliances, and custom storage add value but also add cost.

• Structural and code-related upgrades – Egress windows, stair modifications, or framing and insulation to meet current codes can be a major line item—especially in older homes.

• High-end finishes – Premium flooring, tile, millwork, and specialty lighting will raise the investment but can also increase comfort and resale value.

We walk you through where your dollars are going, help you prioritize, and show you options to keep your project within a comfortable budget while still getting the features that matter most.

Our Basement Finishing Process

Step 1: In-Home Estimate & Basement Evaluation

We start with a free, on-site consultation. Our team walks your basement, listens to how you want to use the space, and notes existing conditions like ceiling height, mechanicals, and moisture concerns. We’ll also discuss budget, timeline, and any must-have rooms so we can give you a realistic estimate.

Step 2: Design, Layout & Material Selections

Next, our designer develops a thoughtful floor plan that fits your goals—whether that’s one large open family room or a full lower-level suite. We’ll review layout options, lighting plans, and finishes, then help you choose materials that look great and perform well in a below-grade environment.

Step 3: Build, Inspections & Daily Communication

Once plans are finalized and permits are approved, construction begins. Our skilled carpenters, electricians, plumbers, and finishers handle each phase with care, following local St. Louis building codes and best practices for basements. We’ll:

• Protect existing floors and living areas

• Coordinate inspections and code requirements

• Provide updates so you always know what’s happening next

Step 4: Final Walkthrough & Warranty Support

When work is complete, we do a detailed walkthrough with you to review the finished basement, answer questions, and address any final touch-ups. You’ll receive information on warranties, finishes, and maintenance so you can enjoy your new lower level with confidence.
