"We chose Design One to remodel our small galley kitchen after meeting with them and seeing their reviews. Initially, they presented as organized and professional. I wish we had asked more questions upfront. The quality of work was poor, especially drywall and basic carpentry skills. The average time spent was 10 hours/week. When they started work, all needed materials were in, yet it took over 7 weeks to complete. Requests for a schedule were evaded. There is no crew it is Rich, and occasionally Linda to assist. Very poor time management at the customer expense. Their lack of transparency regarding certain paperwork was troubling. What should have been a rewarding project became a large disappointment."

"The crew was very professional. Started the job and they made progress every day exactly to my request. They showed me different options and ideas which I appreciated. The job was done quickly, within schedule, and at a reasonable cost, and with great quality. I would hire them again for further work on my home and I will recommend them to anyone because of their hard work!"

"Very nice job building new porch steps, replacing some decking and painting the porch. Frank communicated very well stair options and pricing. Brandon was super friendly and a very good carpenter. My only quibble was that where the stair railing met my columns, the railing was cut perpendicular, instead of round to fit the column. But this is a minor issue, and overall I’m very satisfied."

"Gonzo and his team were excellent. He was easy to work with and had an answer for the different requests and needs necessary for the job. We had two bathroom remodels and I would highly recommend using him for your remodeling needs."

FAQs for basement remodeling projects in Northbrook, 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.
