"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 hired Heartland Village General Contracting and Handyman Services to execute a full, top-to-bottom renovation of our bathroom at the beginning of March of 2026. This was a major project involving demolition , new flooring, updated electrical and plumbing to accommodate a new layout of the bathroom. The company manager/owner, Harvey, was excellent. He provided a detailed project schedule before work began and proactively communicated every step of the way. The quality of the final product exceeded our expectations. Harvey's attention to detail truly made the difference."

"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."

"Your search is over! This IS the guy. If you’re still looking for a contractor for your renovation project you can stop searching. We hired Matt and his team for our renovations and we could not be happier. We put in new floors throughout, a brand new kitchen including cabinets, countertops, sink, plumbing and appliances, new light fixtures and ceiling fans and painted all the ceilings, walls and woodwork. The entire project was done exactly to our specifications; came in on budget with absolutely no surprises and was completed earlier than we could have imagined. Matt’s entire team is totally professional. They arrive on time every day and clean up at the end of the day before leaving. So, stop looking and get your project started with The Finish Guys. We guarantee you will be thrilled with the results."

"We hired TQ Contracting to finish a portion of the basement. Tom and his crew, including Romeo, did a fantastic job and were very easy to work with. They were prompt, effective, and clean, and all inspections passed with flying colors. I was even comfortable letting them work in the basement during periods in which I was not home - this is a team you can trust. I could not be happier with how the basement turned out. Plus he quoted me a fair price that came in over $12K less than another quote I received from a different contractor. I was so stressed trying to find an honest, reasonable, and hard-working contractor and am so thrilled I went with TQ Contracting; the 5-star reviews you see online are 100% legit and they really do a terrific job!"

"I hired Bryan to repair our basement drywall and tile after we had a French drain installed. Overall, I am very pleased with the work his crew did. I had some concerns during the project but Bryan was very easy to talk with. He explained what was going on and any worries I had were put at ease once I saw the final product. I think our basement looks even better now than it did before! I would definitely hire him to come back for future projects."

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.
