"We were extremely pleased with the work they did when we had our master bathroom remodeled. The entire process was seamless from start to finish. They were so professional when they were in the house and kept the entire area contained. I always assumed a renovation would be stressful, but it was not at all. Picking out the materials and fixtures was even fun! The entire team was great and they were exactly on time to the week. They were very responsive to any questions. I highly recommend them, and hope to work with them again in the future."

"Steve and his crew removed an aging deck and constructed a beautiful new composite deck for us. We worked together on every detail for the new deck design and he completed it as designed and with very professional detail. They were easy to work with and kept to the quoted pricing. They also cleaned up the work area at the end of each day--no mess! I highly recommend this dedicated and friendly company. MAR"

FAQs for basement remodeling projects in Collinsville, 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.
