"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."

"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."

"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."

"Santo has now completed the replacement of all doors in our home. Which looks so beautiful and makes our home more up to date and provides such a clean look. Santo installed a new hard wood floor in our entire main floor level. He went to the flooring store to help us pick out the flooring and he was able to advise the flooring rep of exactly what flooring and materials were needed to complete the job. He built valances for our kitchen windows, patio door, and hung the new blinds for us which look fabulous. In addition to providing more storage space for us, he built a coat rack and shelf for my husband's hats in our basement. Saved us space and it looks great as well as being very functional. He built a covering made of wood and placed it around the base of our fireplace to hide speaker wires and it is simply beautiful. Santo is excellent in all that he does and is an expert woodsmen. He is very flexible and will work with your schedule. I HIGHLY recommend him for whatever your home repair needs are. Our friends and family are always complimenting the transformation he made to our home."

"We hired Skies Are The Limit to add a shower in a very small space, and we couldn't be happier with the results. From the start, Adrian was professional and honest about what could realistically be done in the limited area. Adrian came up with a smart design solution that maximized every inch of space. Adrian is extremely punctual and respectful of our time. He arrived exactly when scheduled every day and kept the project moving efficiently without any delays. I would absolutely recommend him based on his punctuality alone! I am looking forward to working with him again in the near future to remodel my kitchen."

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.
