"It was a great experience. Sina and his team were professional and took great care to do a great job. They constantly had new ideas to make the process better and worked with me on ideas I had. Best contractors I have ever worked with."

"Contracted Kurt Becker at Monkâ s to do a small repair and repaint of my foundation, mostly to cover pipes and fasteners from a Generac generator installation. As was done on a previous job, this was finished exactly as I expected; on time, on budget, zero hassle. Would recommend to anyone."

"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."

"I really hate dealing with projects like this as I hear such horror stories from friends and neighbors. But it had to get done so..... Enter ABS Home Improvements. I could tell when I met Thomas that he was a pro's pro. Asked all the right questions and showed past examples of his work. Does not hurt that he has close to 50 reviews and all 5 stars. We hired Thomas, signed the contract and worked out the start date. From demo to touch ups I felt like I was in great hands. No delays that were not for good reasons. His guys showed up when they were supposed to, they were respectful, friendly and very knowledgeable. You just could tell he would not accept anything less than stellar work from his subs. His main guy handled large format tiles like an artist. If I could leave a 10 star review I would do so. Do NOT hesitate to give ABS a call. They were on point and just a pleasure to work with. As well very reasonably priced for the workmanship."

"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."

"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."

"American Home replaced my roof and siding, porch windows and some add-on exterior lighting. One of the reasons I chose AHR was not just due to the best price, they came in line with other estimates I received, but because they included things with their final price that similar companies had as add-ons at an extra cost such as the dumpster and gutter system. I did not know what to expect as this was the first time I've had these things replaced. My rep John was awesome, he was professional, friendly and accommodating, and was able to work with me on the spot vs. "I have to check back to the owners" which I got from other companies. John was readily available by phone, text, and in person. He walked me through all the steps, timelines, and the whole process. After the crew finished, he took my list of 'nit-pick' things and made sure they were addressed. Overall I am satisfied with the job, In fact, we recommended them to our neighbors who hired them to do their siding this Spring."

"We hired Adrian and his team for a much-needed facelift of our front porch, and we couldn't be happier with the results. The entire process, from start to finish, demonstrated a truly meticulous approach to their craft across both projects. Adrian's team skillfully handled every aspect of the porch renovation. They successfully reserviced the floor, installed beautiful new molding, and applied fresh paint all around, which has completely transformed the curb appeal of our home. The quality of the finish on all elements is impeccable and clearly shows their high standards. In addition to the porch, Adrian also installed new windows in our basement area. This was a critical job that involved removing old rotted wood, carefully weather sealing the entire opening, and installing the necessary exterior capping. This detailed work ensures the windows are perfectly watertight, energy-efficient, and aesthetically pleasing from the exterior. What truly set Adrian and his team apart was their incredible professionalism and attention to the small details. Each day, they ensured the entire work area was left absolutely spotless, showing immense respect for our property and minimizing any disruption. We highly recommend Adrian for any home improvement project. Their dedication to quality, cleanliness, and exceptional results is outstanding."

"Inson is a creative genius with a superb eye. He did everything with meticulous detail and completely transformed our apartment into an amazing, gorgeous home. We enjoy entertaining, and our friends love coming over, always remarking how beautiful and inviting our home is- and that was exactly what we wanted, except Inson brilliantly upgraded our concept, within budget and on time (even with our aggressive timeline because we needed to be out of our old place and into our new within months!). Inson’s team was also great to work with - always polite and professional. We highly recommend Inson and plan on working with him again on our Hamptons home!"

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.
