"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."

"I reached out to this company for a sump pump upgrade and a cracked wall repair. The technician who did my install was very polite and informative. We've had several big storms since my installation was done and I'm happy to say my basement has remained totally dry. I'm very glad I chose this company, I would recommend them to anyone in need of help with their basement!"

"We had Tom and his crew remodel our small master bathroom a couple of years ago and invited him back to do our kitchen remodel. Tom and his crew are incredible. They are very professional, considerate, and clean. They do the job right and don't cut corners. His pricing is fair and I would be happy to use them again on my next project."

"The crew did a wonderful job, turning a bare cement basement into a cozy getaway. They framed up and insulated the walls and painting the ceiling black to make it seem larger. They also fixed some rotted railings and installed two new basement windows. Very professional, and were careful to keep things clean."

"We had been burned by fly by night contractors before. Rob assured us that he would restore our faith. He was right!!! He was dedicated, reliable, creative and a pleasure to work with every step of the way on an extensive master bathroom remodel. Along with Ken and Eric, he took the bathroom down to the studs and rebuilt us a 'getaway'. I feel like I'm stepping into a 5 star hotel suite shower everyday when I climb onto our new enormous mosaic floor. In addition to the bathroom, they painted 4 rooms and meticulously prepped every nail hole pop and cracked seam in our aging vaulted ceilings. The house looks BRAND NEW! I highly recommend and can't wait until we can have them back to remodel our kitchen."

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.
