"Basic Bassments did a wonderful job in waterproofing and remodeling our basement. Everyone I dealt with was courteous and very professional. The workmanship was really good…township inspectors commented on good the electrical and plumbing work looked. Basic Basements was always on time and cleaned up after themselves. I highly recommend Basic Basements and would definitely use them again."

"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."

"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."

"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 worked with Prestige on a few, somewhat unique, projects recently, including renovating an old detached garage and fixing up my basement after a French drain/sump pump install. It was definitely a 5 star experience. Matt seemed more like a partner than a contractorâ ¦he brought creative solutions and ideas to the project, was transparent with updates and showing off milestones as they were completed, and even went the extra mile to ensure quality (example: he insisted that siding be sent back because it did not quite match the rest of the house). He also hooked me up with a custom side door for my EV charger cord that is going to make charging outside so much easier. I will definitely be hitting him / Prestige up again in the future."

"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."

"My parents and I live in a old brick apartment building in Hoboken that is from the 1880s. The bathroom in our apartment had not been updated since the 1940s. We needed help ASAP. We checked out Cesar s page and wanted to hire him immediately. The reviews speak for themselves. When he came into our apartment to give us a quote we knew that this was contractor we needed to get the job done. Cesar is affordable, friendly, and very accommodating to any issues or concerns you have before starting the project. Two massive issues with our project were that my dad has spinal & walking issues, so we needed the floors clear of all tools and materials at the end of the each day so that father could walk efficiently through the apartment. The other big issue was that we only have 1 bathroom, so Cesar agreed to work with us on pulling the toilet off and on as every day finished so that we did not have to leave our building to use the toilet. Him and his crew are the best and take pride in their work so that owner is happy with the final result. We brought the bathroom down to the bare bones and rebuilt it back up. I worked with him every step of the way to make sure that he needed all materials to get the job done in the time we needed. This project was an intense remodel with some of the hardest demo and substrate materials that an old bathroom can have. He didn t think anything of it. He has veteran experience in the field and this remodel only took 3 weeks. We are very impressed with Cesar s craftsmanship and professionalism and we will be hiring him again for any future interior projects."

"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."

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.
