"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."

"We recently hired Bonus Home Remodeling to remodel our unfinished basement. Rob and his team were outstanding to work with from the onset of the project. They worked with us to make final design decisions, and throughout the entire project they had a large white board set up in the basement outlining a timeline of the projects so we always knew what was coming up next. They arrived at the same time everyday and left at the same time everyday which made it easy to live through such a big project taking place in your home. Rob and his team made everything convenient and easy for us. Any issues or questions that came up were addressed immediately and always ensured that we were happy before moving forward. The finished project is exactly what we were hoping for! It is gorgeous and the quality of the work is excellent."

"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 purchased a home that was over 108 years old and needed a complete gut renovation for all 3 floors. We met with John Fiore and were very impressed with his responsiveness, flexibility, and partnership throughout this massive project. He responded to calls, email and texts within minutes, was always available and communicative through the process (which is hard to find but so valued, especially as we were living about 1.5 hours away during the renovation). John always did the right thing for the project (either proactively letting us know when changes needed to be made or absorbing costs into the project). For example, the floors got damaged during demo when combining two rooms. He just gave us new floors without asking us to pay because it was the right thing to do. Also, his team was meticulous about laying tiles, mapping out electrical, etc. If we had a problem or didn’t like something, they fixed it at no additional cost. John was so patient and calming throughout the renovation. One thing everyone warned us about was planning for the budget to double through a project this big. John’s team kept such meticulous track of the expenses (including light fixture, tiles, etc) and we actually received a credit towards our project because we stayed under budget for most of our selections. This is completely unheard of and I am so impressed with how organized their processes are. We really felt that Garden State made a big and challenging construction process as positive of an experience as possible. We hired them to do our back deck and have referred them to many of our friends and neighbors who have been blown away by the renovation of our hike. We will hire them for all future projects based on our really great experience with them!"

FAQs for basement remodeling projects in Long Valley, 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.
