"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"

"Ron was very professional during the estimate. He explained two potential ways to accomplish the job and recommended what he thought would would and look the best. The team that installed the window (2 guys) included one of the same men who performed work for me two years ago. It was good to see a familiar face and longevity with the company. He remembered the window and even too time to check his work both inside and out, the latter needing a long ladder to reach. The window turned out great. The trash was removed, the area cleaned, and they were down the road in no time. Highly recommend."

"Wish i could leave ZERO Stars. Reached out to this company (Randy/Jim) for simple estimate/quote. They took full advantage knowing I couldn't lay eyes on the property. They did not complete the work i paid for and were not helpful addressing the situation when reached out. As a result i had to hire someone else to complete repairs! Property Managers Beware!"

FAQs for basement remodeling projects in Bethalto, 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.
