"I have hired many contractors from Home Advisor but this my first review. This team is amazing. They show up on time, clean up after themselves at the end of every day, their work is amazing and they have great attention to detail. I had Owens Corning wall panels in my finished basement, they were here when I bought my house and I hated them from day one; they were too industrial looking for my taste. Anthony and Michael removed all of the double layered panels in a 1500 sq ft basement and disposed of them. They put up drywall, did all of the finishing work, put all 20 receptacles back in, put up floor and door trim and painted. They also replaced two casement windows and rehung two doors that were not installed properly by the previous homeowners. I plan on hiring them to replace the antiquated drop ceiling next."

"We were very impressed by Lux Renovations from the very beginning. The design and quoting process for our basement gym project was well conducted and professional, easy to follow, and thorough. Unlike other contractors we had an estimate the project, a detailed drawing, selected all materials and colors, and had a detailed cost and timeline while the Lux representative was at our house. The Project Management and build team was excellent to work with. Their work was top notch, clean, and completed on time and budget. We couldn't be happier with our basement home gym."

"I had my 1960s paneled and drop ceiling basement room remodeled. I cannot tell you how pleased I am at the upgrade. Along the way Gary answered many emails and calls in a timely manner, usually within the hour. He gave me updates of when certain parts of the project would be worked on and made suggests on things that I hadn’t thought about ( like replacing the drafty original windows while construction was happening). He picked out doors and ceiling fans that were perfect since I am not good at decorating. Because GJP has all their own contractors there was no wait time between the remodeling of the walls and the electrical work that needed to be done. All the workers were do polite and diligent and cleaned up the area. I cannot put into words how wonderful the whole process has been and have already given references to friends. "

"Did a wonderful job. Floor seamlessly connected with existing floors. Bathroom went from blah to a beautiful oasis. Made sure we got (or exceeded) what we wanted. Hard working, honest, and trustworthy. Cleaned up every night when they finished for the day. 100% will use again. 100% recommended. "

FAQs for basement remodeling projects in Delaware City, DE

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.
