"On behalf of the family, we would like to thank M&J Home Services for the beautiful bathroom renovation they completed in our home. Jeff designed and remodeled a bathroom thatâ s completely updated now. The shower has all the bells and whistles! His motto â Whatever you want done, we can do it for youâ is absolutely true. His skill set is unmatched. A linen closet enhances what was originally there. He is a master of all trades and was able to refinish the deck too. We are grateful to Jeff and Milena for their hard work and perseverance in completing the job in a very professional way. They are trustworthy and respectful of the property they are working on at all times."

"Matt and his team did a phenomenal job. Going into the project, my biggest concern about hiring a contractor was reliability—I had heard too many stories about contractors not showing up or following through. Matt completely put those fears to rest. He was always available to discuss any concerns and personally visited the job site to make sure everything met my expectations. His top priority was ensuring I was happy with the work. Even months after the project was completed, when a small issue came up, Matt followed through and made sure it was corrected. I had completely gutted my kitchen, and I couldn’t be happier with the results."

FAQs for basement remodeling projects in Princeton Junction, 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.
