He and his associate dug and built a new base, constructed the shed (which was BEAR of a project) roofed it, painted it, and built a custom ramp for the shed. Throughout the entire project John was communicative, transparent, professional, timely and did a stellar job throughout the entire project. We are beyond satisfied with the results.

"I?m sad to write this review as Hero started off as a wonderful landscape partner to us with excellent communication and integrity. Unfortunately this past year we paid for a season pass of bi-weekly lawn mowing services plus an additional spring clean up service. We tried to work things out with Hero but ultimately we received fewer than half the lawn visits, no spring clean up and the visits we received were sporatic and not on the promised timeline. Hero agreed to come by with the refund for part of the services he did not provide but has since ghosted us despite consistent attempts to reach out by phone, text, Zelle and in-person. We lost $480 in services."

FAQs for basement remodeling projects in Winnetka, 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.
