"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 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 had my basement waterproofed and couldn’t be happier with the results. They were knowledgeable, professional, and very easy to work with. They showed up on time, kept everything clean, and made sure the job was done right. I would absolutely recommend them to anyone needing waterproofing work!!"

"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."

"We had been burned by fly by night contractors before. Rob assured us that he would restore our faith. He was right!!! He was dedicated, reliable, creative and a pleasure to work with every step of the way on an extensive master bathroom remodel. Along with Ken and Eric, he took the bathroom down to the studs and rebuilt us a 'getaway'. I feel like I'm stepping into a 5 star hotel suite shower everyday when I climb onto our new enormous mosaic floor. In addition to the bathroom, they painted 4 rooms and meticulously prepped every nail hole pop and cracked seam in our aging vaulted ceilings. The house looks BRAND NEW! I highly recommend and can't wait until we can have them back to remodel our kitchen."

"After getting quotes and meeting 3 other contractors, we easily made the decision to hire JK Custom Building & Remodeling to finish our large basement. From the very start John was able to offer suggestions and was very knowledgeable regarding every aspect of construction. From the first stud that went up to every detail along the way, John and his crew were excellent craftsmen. We really liked the fact that John was hands on and kept us updated several times a week as to what and when to expect the various phases of the construction. His skill and workmanship is superior. My family and I have stated throughout that we were so lucky and fortunate to have selected him and his company. He used only the best, high quality materials and gave us great suggestions. Our basement looks absolutely amazing! Janet & Phil L. Cream Ridge, NJ"

FAQs for basement remodeling projects in Trenton, 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.
