"Angelo & team were amazing to work with. From design to implementation, it was a smooth experience. We had the same crew working at our house every day- the guys were friendly, polite, tolerated my 5 year old daughter asking them what they were doing each day (LOL). Their work was top notch- no corners cut. Every day they left my house clean, nothing left out- all materials put away and the rooms were safe for my kids and dog to be in. We couldn’t be happier with the work done. "

"Absolutely amazing experience. SO EFFICIENT, always on time, GREAT value, unbelievable communication, and tremendous transparency. The contractors were so GREAT at what they do, and were clean and always on time. No hidden costs or expense (which you deal with with MOST contractors). This is not the best contracting company I have worked with, this is the BEST COMPANY I have ever worked with."

"Roberto and his team helped us select, paint, and install a large custom french door for our home office. Roberto understood our vision, made the process simple, and handled the project efficiently. Roberto was quick to respond, and showed up exactly when he said he would to make sure his team was on time and understood what we wanted. We are so happy with the way the door came out, and highly recommend Roberto and his team at Monk's."

"Carmelo and his team really raised the bar! They were super responsive, easy to reach, and clearly cared about making sure we were happy every step of the way. Carmelo was flexible with material choices and kept us in the loop with great info and advice while we made decisions. He renovated both of our bathrooms and installed hardwood floors in our living and dining rooms. Each bathroom was done in just two weeks—and they look incredible! The work was top-notch, the price was totally fair, and the whole process was smooth and stress-free. I’ll definitely be hiring Carmelo and his crew again. Couldn’t recommend them more!"

Customers say: Quality work

"JM did a fantastic job. About 13 years ago, while living at our previous residence: JM remodeled and modernized our full Kitchen, two full bathrooms and, after many tries by other contractors, he was able to stop a leak from our roof at no charge. About 10 years ago, at our current residence , JM remodeled and modernized our full kitchen and did a unique job of updating 4 large sliding closet doors. He removed the cheap inserts, and replaced them with 1/4” high quality plywood into the frames. He then, using wood molding, he made the face of the doors look like real wood doors. Doors were stained and look like expensive oak doors! JM comes up with excellent suggestions, alternatives, and expense saving ideas. We plan on relying on his expertise when we’re ready to upgrade our Patio. All the best to JM Group!"

"Service was great from sales, to installation, to post installation support. Very responsive, very professional. It's hard to find in this 'space'--there are a lot of shady people in basement water damage/repair, and this place exceeded expectations. We've had our repair in place for 4+ years, with only 1 small issue on a wall seam crack, and that was fixed within 24 hours of reporting the issue. Stand up place! Thank you for such great service and support."

"If I could give them 10 stars I would. I had Garden State Home Remodeling come to pave my old torn up driveway and yard space and replace with asphalt. This was my first major home project and I was really nervous. Kelvin walked me thru the entire process from beginning to end. Kelvin was so professional and answered every question I had. Everything I asked for was done over and beyond. The crew did an excellent job on my driveway/yard. I’m more than happy and will use their services again!"

FAQs for basement remodeling projects in Whippany, 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.
