"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."

"I reached out to this company for a sump pump upgrade and a cracked wall repair. The technician who did my install was very polite and informative. We've had several big storms since my installation was done and I'm happy to say my basement has remained totally dry. I'm very glad I chose this company, I would recommend them to anyone in need of help with their basement!"

"My basement got flooded during IDA, after contacting with couple of contractor I met with Matt, He came on time and explain everything what needs to be done also provide a reasonable price. He started to work immediately with his team. His work was very professional, he did everything as he promised and completed the work on time. He was the most professional, clean and trustful contractor I have met so far. He was always top of the every process and he was paying attention to every small details even I didnâ t see them during the construction. I highly recommend him, I also started recommending him my friends. I will 100% contact him even if I have a small project in the future, Thank you Prestige Design and Build for Beyond Expectation."

"I hired Tom to install two new storm doors, a new awning over the back door, new lattice work, and a new door bell. Tom was quick in responding to my initial call and all my texts that followed after I hired him. Tom was always on time and extremely friendly and professional. He is a perfectionist. Tom will not say a job is done until he is fully satisfied with the finished product. I would strongly and highly recommend Tom and ABS Home Improvement for any and all work you may need around your home."

"I am so grateful that I was able to find Jorge after our house was broken in through the sliding door just before Thanksgiving. He replaced the sliding door the next day I called him. He was actually the only one who prioritized this work to meet our emergency need among the contractors whom I had contacted. He also fixed all the others damaged by the burglars. The price was very reasonable and fair. Jorge is a great pleasure to speak with and knowledgeable. He is very detail-oriented at work, pursing perfection on every detail. He always ensured the job was completely finished without question. He did amazing job on everything I asked for that I continued to ask for more projects to be completed, which included painting, window replacement and basement remodeling next year. I would highly recommend his company for any of your home projects."

FAQs for basement remodeling projects in Westfield, 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.
