"I highly recommend Ed to all of my clients and use him personally for my projects. His response time is incredibly fast. He is very reliable and shows up when he says he will which is rare in the contracting business. He even follows up multiple times. He has done it all, from putting together furniture to remodels for me and my clients. His team is great at getting this done quickly and taking pride in their work. He takes great care of clients and is a very good listener to understand his clients' needs. Sometimes he even comes up with ideas that I have never even thought of. Very good at improvising and finding solutions to some items that seem like they can't be fixed. As a broker it is so important to have someone capable and professional representing you. In summary, Ed is finally the contractor that I have been looking for and will use for all my future projects!"

"I am so grateful to Grandview Construction for our beautiful, new kitchen and master shower! They also painted our entire first floor including the trim. Our experience with Jeremy and his wonderful crew was A+mazing! Their workmanship was excellent, and Jeremy was very communicative and responsive throughout the entire process. The crew was friendly, professional and clearly experts at what they do. One of them has almost 30 years of experience in the industry. Jeremy and his crew provided many helpful details about the project from start to finish and was quick to let us know if any issues arose. When they had to make any adjustments they explained the reasons and were very patient in answering all of our questions and since this was our very first kitchen remodel we had a lot of questions. The project was completed on time and stayed within the very fair competitive estimate he gave us in the beginning, and we could not be happier with the gorgeous finished product. We will work with them on any other project we might do on our home, and I would recommend Grandview Construction without any reservation to anyone who is looking for a dependable and honest general contractor to work on their house."

FAQs for basement remodeling projects in Downers Grove, 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.
