"Shawn and his team are very easy to work with. They are always on an even keel no matter what issues may arise. They manage a project seamlessly, and easily adjust where necessary. They leave the project clean every day, as they would leave their own home. Their communication between the client and others involved in the project is second to none. I will happily continue to refer CoCara Remodeling."

"LOVED, LOVED, LOVED working with STL Build Pro! They remodeled our basement and made it an amazing space, that we are already enjoying! Our basement was completely unfinished - they worked with us to design the entire space. We added a living space, wet bar, bedroom, play area, 2 bathrooms (one full bath and a half bath) and laundry area! Every member of the team is extremely professional and courteous and so enjoyable to work with - even our kids loved having them around and talking to them every morning before they left for school! They made sure we were happy and satisfied with each part of the basement. They pay attention to every little detail! We added on some small projects upstairs as well, and they were very accommodating to any additional renovations we wanted to do or any changes we requested to things they were already working on in the basement. I would highly recommend them for any project - I already have some renovations I plan to do in the future and will be reaching out to them again for that work - I wouldn't use anyone else!"

"Jonathan did an amazing job with our bathroom remodel. This was a complete remodel with an oversized shower, patterned ceramic tile, beautiful sliding glass doors, and of course the sink, toilet and flooring. The job was done very well and in good timing. He was very professional and kind. I would highly recommend his team for any work that you may need done!"

Hello there! I'm a Saint Charles/Saint Louis native and an experienced carpenter and remodeller of 17 years! Been in my own business since 2022. I love to do beautiful work at reasonable prices. I am focused on design-minded small construction and carpentry--this means that I am not primarily so focused on flashy features and the newest updates, and more focused on how I can create a project with you that makes sense with your specific house and it's architectural design. I love working with wood the most but really love doing most anything on a home and happy to do handyman work here and there as well. Please reach out so we can start a conversation! I'm happy to offer advice on how to navigate the construction industry or send you phone numbers of other great guys if you need other services. I focus on approachability and a down to earth experience. I love doing good work, i'm easy to deal with and show up when I say I will. Would love to work with you!

"I had a small job, to have two yards of clean gravel delivered to my driveway for a paver project. Christian called me almost immediately after my Angi request, and gave me a quote. He delivered on time, and his customer service was spectacular. Probably the best service I’ve had since I’ve been using Angi. I’d highly recommend him to everyone."

FAQs for basement remodeling projects in Belleville, IL

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
