"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."

"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!!!!!"

"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."

Customers say: Quality work

"We recently completed a major multi room renovation which included a new kitchen and den renovation requiring an expansion of our foundation along with removal of exterior and interior walls. Additionally the reno included a new back deck and front portico. We could not be happier with John and the job that he did. What impressed us most with John was his reliability. Over the course of this 4+ month project, John was at our house first thing each and every weekday morning, and had his team there as well. They were professional, courteous and kept the house clean and functional enough that our whole family was able to live in the house while the renovations were taking place. John initially quoted us that the project would take 4 months and they remarkably stuck to that schedule. The end result has been everything that we wanted. The pictures speak for themselves, but the craftsmanship and attention to detail they put into the project were exceptional. John was forthcoming with suggestions or advice, and very transparent when any changes or surprises popped up. He was truly a partner in the effort and we would strongly recommend him for any projects that you may have. Sincerely, Ann & Steve Marcus"

"Professional team providing excellent quality work! This included creating a laundry room from a closet, connected through to the bathroom, remodelled bathroom, painted, refinished wood flooring, installed kitchen cabinetry and built/installed a custom hutch as a storage unit. Very responsive, knowledgeable, trustworthy and offered best practices/recommendations along the way. Their team had eased any initial concerns I had with what could have been a daunting project for me. Very appreciative of their service and would use them again in the blink of an eye. Good luck with your project!"

"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.
