"Joseph and Sons had done our waterproofing in our finish basement. What I liked about this company was, they were the only company to do waterproofing and finish our basement with Sheetrock, trim, trim and floors. A one stop company that does all. Always delt with Angelo and he was very knowledgeable. Will be using them for future jobs."

"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."

"We went with Matt and team for our kitchen remodel and the process could not have been smoother. The project was completed to our standards, on time, and within budget which is really all you can ask for from a contractor. While Matt did not give us the cheapest quote, we found the pricing fair and even asked him to complete some additional projects, like replacing our front door. Matt was professional and easy to work with and told us exactly what needed to be purchased and when which helped keep everyone on track. We would highly recommend Matt and team and plan on using them for additional projects in the future."

"Cesar remodeled our basement, and we cannot be happier with his work! He worked with us the whole way to make sure we were happy with the work. He even put a custom wine rack in. The new basement is so beautiful and we get so many compliments. He has done work for us before and he does excellent work, is always available and easy to reach, and has a professional and kind team of workers. Thank you Cesar!!"

"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."

Customers say: Quality work

"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!"

"Hired this company after interviewing two other companies to remodel my kitchen. My husband and I were saving for quite some years to have this project done so we wanted the best contractor that we trusted to do the work. They came in to our home (on time with the appointment) and explained every detail about the job step by step. We really appreciated this and we didn’t feel rushed or pressured. John the sales rep was willing to spend as much time needed to answer our questions. We did not get the same sense of patience from other contractors. Although not the cheapest or most expensive we are happy we selected Garden State Home Remodeling for our extensive kitchen rehab. Thank you Garden State Remodeling Group for a job well done."

"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."

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.
