"We had a great experience with the Lux Renovations and Owens Corning team. The whole process was very easy from designing the space, selecting colors, and having a contract manager who organized the entire basement remodel including all the trades and inspections. We were sold on the Owens Corning materials for the basement and that they were engineered specifically for a basement space. Would highly recommend this team for your basement remodel needs."

"I hired Bryan to repair our basement drywall and tile after we had a French drain installed. Overall, I am very pleased with the work his crew did. I had some concerns during the project but Bryan was very easy to talk with. He explained what was going on and any worries I had were put at ease once I saw the final product. I think our basement looks even better now than it did before! I would definitely hire him to come back for future projects."

"The best contractors to work with. I have used them at our medical office, home, and rental properties. They are professional, do quality work, at a reasonable price. Everything they have done for us has lead to people asking who renovated our office, who installed the wall paper, built our custom closets, and did a full kitchen and bathroom remodel. They work around your schedule to keep your business running, and clean up as if they were never there. They pay attention to the small details and make sure your vision comes to life. We never felt nickel and dimed for every little thing. The best part is they are great people who take pride in building relationships and doing quality work."

FAQs for basement remodeling projects in Trenton, NJ

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.
