Turn the space under your house into the best room in it.
Most basements are storing boxes when they could be the favorite room in the house. We finish basements into family rooms, guest suites, home theaters, and bars that feel like they were part of the original plan, not an afterthought tacked on underground. We finish basements across Swansea, Belleville, Mascoutah, Freeburg, and the surrounding Metro East.
What does finishing a basement in Belleville include?
Padgett Building & Remodeling finishes basements across Belleville, Swansea, and the Metro East, turning below-grade space into living space without changing your home’s footprint. One recent Padgett basement added roughly 1,500 finished square feet: two bedrooms, a family room, and a full bath. The family has built and remodeled here since 1992.
That 1,500 square foot job is the one homeowner Tony Hart hired us for, and it is a good picture of the scope we handle: framing, egress, plumbing for the bath, and finish work all managed by one family-owned crew.
- Family rooms and rec spaces
- Bedrooms and guest suites
- Full and half bathrooms
- Wet bars and kitchenettes
- Egress windows for safe bedrooms
- Moisture and insulation detailing
- Recessed lighting and built-ins
- Home theaters and offices


No shortcuts, where it matters most.
A basement has its own rules: moisture, egress, and headroom all have to be handled right or the finish work fails later. We detail the unglamorous parts correctly first, so the beautiful part lasts.
The Padgett Way →How do you finish a basement so it stays dry?
The difference between a basement that stays dry and comfortable and one that smells like a basement is all in the order of operations. Here is how we do it.
Moisture & waterproofing
We start at the source. Grading, any water issues, and a vapor strategy get handled before a single stud goes up, because nothing you build on top matters if the space is damp.
Insulation & framing
Walls are framed off the foundation with the right insulation detailing, so the space holds temperature and stays comfortable in every season instead of fighting the concrete.
Egress & safety
Any basement bedroom needs a code-compliant egress window for a safe exit. We plan it early, along with smoke and carbon-monoxide detection, so the finished space is safe and legal.
Finish & trim
Only now does it become a room. Drywall, flooring, lighting, built-ins, and trim go in over a base that was done right, so it looks and feels like the rest of your house.
What shapes the cost of finishing a basement?
What you spend on a finished basement depends on the work the space needs, not a flat rate. Below-grade rooms carry costs that above-grade ones do not, from egress and waterproofing to a new bathroom’s plumbing. Padgett quotes each basement after a free consultation, with no surprise change orders.
Egress & waterproofing
Cutting an egress window and well, plus grading and vapor control to keep the space dry, is foundational work that a bare basement does not already have.
Adding a bath or plumbing
A full or half bath means running supply and drain lines below grade, which is one of the biggest swings between a simple rec room and a full living suite.
Framing & insulation
Walls framed off the foundation with the right insulation detailing hold temperature and comfort, and the size and layout of those walls shape the material and labor.
Ceiling height
Low headroom, ductwork, and beams can call for soffits or rerouting to keep the finished ceiling comfortable and code-legal, which affects the plan.
HVAC extension
Heating and cooling has to reach the new rooms, whether that means extending the existing system or adding returns, so the space stays livable year round.
According to the International Code Council’s International Residential Code, any basement with a sleeping room must have an emergency escape and rescue opening, which is why every bedroom we finish includes a code-compliant egress window and well.
Common questions about finishing a basement in the Metro East.
How much does it cost to finish a basement?
Padgett prices every basement individually, so there is no set square-foot rate. The cost is shaped by egress and waterproofing, whether you add a bathroom and its plumbing, framing and insulation, your ceiling height, and extending HVAC. After a free consultation we give you one honest quote with no surprise change orders.
Do I need an egress window for a basement bedroom?
Yes. Under the International Residential Code, any basement with a sleeping room needs an emergency escape and rescue opening. Padgett handles the cutting, the egress window, and the exterior well as part of the project, so every bedroom we finish is safe and code-compliant.
How do you handle moisture and waterproofing in a basement?
Padgett assesses moisture before any finishing begins and details grading, vapor control, insulation, and flooring to suit a below-grade space. If there is a water issue, we address it first rather than finishing over it, because nothing you build on top lasts if the space stays damp.
Do you pull the permits for my project?
Yes. Padgett pulls the building permits your basement project needs and handles inspections, including the egress and electrical work that basements require. You get one accountable contractor managing the paperwork and the crew, so nothing falls between the cracks and the finished space is fully legal.
Do you finish basements in Belleville, or only Swansea?
Padgett is based at 4200 Smelting Works Rd in Swansea and finishes basements across Belleville and the wider Metro East, including O’Fallon, Shiloh, Fairview Heights, Mascoutah, and Freeburg. The family has remodeled and built in these towns since 1992, so Belleville basements are close to home.
