"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."

"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."

"My husband and I are beyond grateful to All-Star contractors for doing an excellent job on finishing/remodelling our basement. We never imagined that our basement will look this good despite the small size (we live in a townhome). Every space was made functional. Bill (the contractor) is very fair, always listen and give recommendations as needed. The price is appropriate for the excellent work done. Bill's crew is very hardworking and takes pride in his work - making sure that we will be pleased and always asked if there is anything or issue that needs to be addressed. We are in the process of lining up our next project with Bill. We will definitely not settle for another company for any work we need whether it is something minor or major. If you are looking for someone trustworthy - we will definitely recommend Bill without a doubt."

"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."

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!"

"A+++ We hired DMR Millwork for a complete kitchen/laundry remodel and couldnâ t be happier with the results. They provide high quality work - very detail oriented, clean, timely and courteous while providing updated timelines throughout the project. We changed plans several times during the project (mostly adding features) and Dave was very flexible and supportive. Communication was excellent throughout. Highly recommend!!"

FAQs for basement remodeling projects in Warren, 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.
