"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!"

"My wife and I hired Joseph and Sons to remodel our basement. Angelo was accommodating and transparent with us at all times, suggesting solutions for each of the ideas and challenges we had, from fixing the homeâ s foundation, to custom creating our bay window, to matching our staircase and floor finish. They took the time to explain all the options within our budget and talk through each with us to make sure we were happy with the direction of the project each step of the way. His team is respectful and skilled, and there was constant communication regarding timeline, as well as arrival and departure times for each day of work. Attention to detail and a desire to make us happy were constantly present and I always felt like I was the only project they were working on; I would hire them again and recommend to my family and friends."

"DMR did a wonderful job installing the vinyl planking in my kitchen and dining room. Dave also installed new closet doors in the master bedroom. I am thrilled with how the both projects turned out. I am planning on doing more renovations in the spring and will definitely call Dave to do the work."

"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."

"I hired Giove Renovations the first time to help me with a kitchen/dining room overhaul a few year back. They turned the two crowded rooms into an amazing bright open space. They added small trim and crown molding to make the cabinets and room in general look amazing and custom-made for the space. They made suggestions that didn't increase the price of the job, but improved the functionality and overall look of the space. From suggesting to include small shelves to soften the end of some cabinets to staining wood switch plates so it would blend into the side of a cabinet. We were so pleased with the work before they finished that we decided to do all the remodeling on the first floor that we were considering for future dates. That included changing a drop ceiling into a regular sheetrock ceiling, moving the laundry room from the basement to the first floor and adding laundry area cabinets, upgrading a basement wetbar and adding decorative tile work, refinishing existing hardwood floors and installing new hardwood floors in the kitchen and laundry/mudroom. The next time I hired them they added a door to connect the main house to the attached garage and a second door from the garage to the backyard and an overhaul of the garage including additional insulation and paint. This very last time I hired them they painted 3 bedrooms, installed a bunch of doors and 2 sets of double doors which needed a saddle installed as well. And the craftsmanship for all of that work, the big and the small stuff was meticulous and just amazing. Not a stray drop of paint or misaligned corner anywhere."

"JM did a fantastic job. About 13 years ago, while living at our previous residence: JM remodeled and modernized our full Kitchen, two full bathrooms and, after many tries by other contractors, he was able to stop a leak from our roof at no charge. About 10 years ago, at our current residence , JM remodeled and modernized our full kitchen and did a unique job of updating 4 large sliding closet doors. He removed the cheap inserts, and replaced them with 1/4” high quality plywood into the frames. He then, using wood molding, he made the face of the doors look like real wood doors. Doors were stained and look like expensive oak doors! JM comes up with excellent suggestions, alternatives, and expense saving ideas. We plan on relying on his expertise when we’re ready to upgrade our Patio. All the best to JM Group!"

FAQs for basement remodeling projects in Cedar Knolls, 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.
