"We love our basement remodel. Peter, Alex and his team were here when they said theyâ d be here, completed the job as described, and kept us updated along the way. The basement now looks and feels clean and bright. The additional space doesnâ t feel like a basement at all and is enjoyed by the whole family. We highly recommend Lux Renovations."

"Garage Lux general contractor has done many projects for me which was done professionally and on time. They removed my old garage door and replaced it with regular door and screen. My old front door was removed and replaced with new door. My back porch gutters were removed and replaced and the old wood was torn off and replaced with new wood. All the old screens were replaced with new ones and a new fan with light fixtures was installed by them. I would recommend them if you are in need of work to do around your home. I would give this company a 10 out of 10."

"We just got our basement remodeled by Blue Ridge Builders and we are extremely satisfied with their performance. The basement looks outstanding and the finish mirrors that of our main floor upstairs. We could not have hired a better builder. Wayne and his crew demonstrated to us that they are real professionals. The structure and finish is solid. My wife and I were looking for honesty, dependability and professionalism; Blue Ridge Builders demonstrated all of the above and more. Thank you so much Wayne. We would definitely recommend Blue Ridge Builders."

FAQs for basement remodeling projects in New Castle, 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.
