Customers say: Quality work

"Jeff had done beautiful work at my parents house so I was excited to use him for a kitchen remodel in my first home. He is always friendly, professional, and responsive. He can handle any kind of issue that may arise, such as the need to move an unexpected vent. For our kitchen he tore down a pantry closet and the soffit, installed new flooring, cabinets, backsplash, shelving, range hood, lighting. He has great recommendations and his attention to detail is impeccable. We highly recommend Jeff and his team for your project!"

"We had a wonderful experience working with KSRP Construction! From initial contact to job completion, communication was always very prompt and concise. We were needing to build a wall to close up our loft (to convert into a bedroom) and KSRP provided fair pricing, were quick and efficient and got the job done right. Roberto and Sebastian were incredibly professional, polite, skilled and detailed. Not only were we impressed with the work itself, but these guys were so thorough from initial tarping to final clean up. We have several neighbors and family members who are planning future house projects and you best believe we've already highly recommended KSRP Construction - specifically Roberto and Sebastian for the job!"

"Dean and his team were great to work with. They understood our vision with our basement reno from the beginning and made it a realty. Their crew was very professional, always communicated well and does really good work. They also were the lowest quote out of the three I received! Great quality and value."

FAQs for basement remodeling projects in Wilmington, 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.
