"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 have known Bill since 2005. At that time he built an addition of a bedroom suite and bathroom to our new home. Since then he has answered our calls for projects small and large. Among the things he and his crews have done are a kitchen remodel, new flooring, master bedroom suite addition, deck, siding, finished the basement, and a garage with a 2 story building attached with the first floor a dance studio and upstairs a game room. Bill is always responsive and listens to what the customer wants. He has always provided me with top notch service."

"During the initial quote process Tom was very knowledgeable and put together a great plan for basement remodeling. My basement was transformed from the style of 50's to a modern basement that I can enjoy with my family. The staff was friendly and worked diligently 6 days a week without interrupting to my day. I received updates through the project from Tom on the progress. The company provided completive rates and this was the best money spent. I would highly recommend this company to anyone looking for quality work, your will not be disappointed."

"We found RW Contracting through Home Advisors. Before we started we got a few estimates and we decided to go with them. They gave us a reasonable estimate (not the cheapest) but included more and Rich definitely had a great vision of what our finished basement could look like. Rich is a definite pro at finishing basements and so easy to work with! He suggested replacing old casement window and including some built-ins and half walls stuff that we weren't thinking about but I'm so glad these enhancements are part of our finished basement. Rich and his team were wonderful to work with. No concerns with them in the house alone. They were honest, clean, courteous and always on time. Rich personally managed the project from start to finish, he is extremely accountable. We are so happy with our finish basement and we give Rich the highest recommendation. You won't be disappointed, he is one of the best (and we are very particular)!"

FAQs for basement remodeling projects in Flemington, 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.
