"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."

"Carmello is great. After a flood ruined my basement these guys completely repaired and renovated the space including new french drains, vinyl sheeting behind the drywall, dry locked the window wells and caulked all necessary gaps. Not cheap but they knew exactly what they were doing and since our area has had several storms w record rainfall and my basement has been bone dry. Would use them again in a heartbeat. Highly recommend."

"My basement got flooded during IDA, after contacting with couple of contractor I met with Matt, He came on time and explain everything what needs to be done also provide a reasonable price. He started to work immediately with his team. His work was very professional, he did everything as he promised and completed the work on time. He was the most professional, clean and trustful contractor I have met so far. He was always top of the every process and he was paying attention to every small details even I didnâ t see them during the construction. I highly recommend him, I also started recommending him my friends. I will 100% contact him even if I have a small project in the future, Thank you Prestige Design and Build for Beyond Expectation."

"We just had our basement finished. Not re-finished but finished for the first time. The house was built in 1924 with a dirt floor in the basement and low hanging pipes, overall a very challenging job. We wanted to turn it to a family room with a full bath, laundry room, closets, etc. Joe's guys (Chico and Javier) did a fantastic job. They are knowledgeable, thorough, thoughtful, and creative. We would recommend them to anyone without hesitation."

"We needed the playroom in the basement to be refreshed: new floor, windows and paint. We also added a custom closet and had the central AC ducts encased. We had already hired BAS Construction a few years ago to finish part of the basement, and wanted the playroom to match. We were again very pleased with the results. The various crews showed up on time and the work site was kept clean. The work was completed within the promised time frame. Ali and Sina were easy to work with and very professional, from planning the project to completion. They came up with great suggestions. We would highly recommend hiring them."

"100% recommend these guys. Aaron was very professional and provided fair pricing. Really appreciated that they were straight forward in their estimates and timing. We got our wallpaper removed and walls painted in one of our bedrooms. Wallpaper removal is super tedious and they did a phenomenal job. Even did a couple extra things without being asked, which we really liked! We were very happy with the quality of work, so much so, that we asked them to do another job for us - repairing our shed in the backyard. Once again, they delivered great work in a very timely manner. Will definitely plan on using this company again in the future for other home improvement jobs!"

FAQs for basement remodeling projects in Whippany, 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.
