"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."

"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."

"Ryan & his team were wonderful & our bathroom came out beautifully! Ryan was extremely informative and helpful, answering our countless questions both before and during the remodel job. He worked diligently for three weeks to bring new life to the space. The quotes were also incredibly affordable given the high quality of the work. We would 100% recommend Indigo & we look forward to working with them again very soon."

"Cesar and his crew just finished a remodel of my master bathroom. This is the second major project completed in my home by CSZ (prior kitchen remodel) and once again they exceeded my expectations. Cesar worked with me along the way to come up with the perfect design to ensure all my requirements were met. He is knowledgeable and his attention to detail is second to none. The CSZ crew, Armondo and Benjamin were also a pleasure to work with. They are knowledgeable, trustworthy, and hardworking. They also did an exceptional job cleaning up at the end of each work day. My dog even loves them! I highly recommend CSZ Construction. They will most certainly be back for future projects in my home!"

"American Home Remodeling was absolutely stupendous to work with. I reside in Irvington and needed vinyl siding and 3 windows replaced to my home. Victor, Kelvin and their team of workers were efficient, service-oriented, and professional from the pre-planning stages- through the completion of the project. I highly recommend their services. Their work was clean, and gave my home a tremendous, refreshed look. A BIG thank you to Vic, Kelvin and the American Home Remodeling team. You guys are ROCKSTARS!!!!!"

"If I could give them 10 stars I would. I had Garden State Home Remodeling come to pave my old torn up driveway and yard space and replace with asphalt. This was my first major home project and I was really nervous. Kelvin walked me thru the entire process from beginning to end. Kelvin was so professional and answered every question I had. Everything I asked for was done over and beyond. The crew did an excellent job on my driveway/yard. I’m more than happy and will use their services again!"

"Jorge and his team were awesome from start to finish. I reached out to them for a company to frame and drywall my basement remodel, but after meeting with Jorge I knew the could handle the entire job from demo to finish. Jorge was great to work with and his team was great as well. Jorge can handle any project that your home may need. Highly recommend this company."

FAQs for basement remodeling projects in Union, 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.
