"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 are currently happy with the basement waterproofing and remodeling that was completed! There were issues - most minor but we haven't anything to compare as this was the first-time having contractors complete basement work for us; and our home is almost 100 years old. They were flexible given unexpected issues that came about with the basement. The water proofing was done first and they did a great job. They were happy to review and resolve any remaining questions/concerns and/or issues. Jorge in the service dept. is professional, punctual and is a great representative and asset for this company."

"My husband and I are new homeowners in Yardley; we interviewed 10+ contractors in the area to complete a basement remodel at our home. Renovations can be scary and we were very adamant about choosing the right partner for the project. We are so glad that we chose Improverite! Robert and his team are truly the best in the industry! Robert is a high-energy, passionate professional who made sure we had a first-class experience. Every part of this process exceeded our expectations. He was diligent about earning our business and building our trust. I really can't put into words how good his team is! Everyday I was blown away at the progress and craftsmanship of their work. I was not expecting that level of talent and customization to go into the project. We have a space that is above and beyond anything we were expecting and could not be happier and pricing was very competitive! The gentlemen at Improverite are thoughtful, professional, and incredibly skilled at their work. We highly recommend them and will absolutely use them for our next home project!"

"We needed some work done in our basement and needed the work done quickly. Called Harvey and the work was done in 3 days and at a fair price. They remodeled our home in the poconos in less than one month and we get so many compliments from our renters. We will definitely use their services again. Thanks Harvey!"

"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."

"I recently had the pleasure of working with The Finish Guys for a basement remodeling project, and I couldn't be happier with the results. From start to finish, the experience was exceptional, and I wholeheartedly recommend their services to anyone in need of a remodel. The team's punctuality and responsibility were outstanding. They consistently arrived on time, and their professionalism was evident throughout the project. I must also commend Matt, who was our main point of contact. His level of communication was top-notch. He kept us informed every step of the way and was quick to address any concerns or questions we had. Matt's dedication to ensuring our satisfaction was truly impressive. The quality of their work speaks for itself. The Finish Guys transformed our basement into a space that exceeded our expectations. Their attention to detail and craftsmanship are evident in every corner of the remodel."

"We had Tom and his crew remodel our small master bathroom a couple of years ago and invited him back to do our kitchen remodel. Tom and his crew are incredible. They are very professional, considerate, and clean. They do the job right and don't cut corners. His pricing is fair and I would be happy to use them again on my next project."

FAQs for basement remodeling projects in Princeton, 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.
