"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."

"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."

"This company, the owner and all key members of his team were exceptionally great to work with from start to finish of our master bathroom remodel. We can’t thank Vince, Justin and Evaldo for their attention to every detail from the initial contact, selection process (the owner himself guided us through) and demo to remodel. Each member of the team made sure the project ran on time and was performed to the highest standard of excellence. All the men who came to perform the hardest of tasks were timely, courteous and respectful of our home. We have had previous unfortunate experiences with contractors that left us not knowing who to trust when considering such a major investment in our home. Angie’s List provided us with this excellent recommendation , proving its ability to stand behind its name as a brand people could trust. We wholeheartedly recommend this company to anyone who is considering the best possible return on their investment into their home. "

"Our existing Owens Corning wall panels had been damaged in a basement flood. Although the framework and panels had changed since our initial install some 20 years ago, they custom made new panels that fit perfectly. Additionally, they replaced interior doors and repaired drywall. The work was done on our schedule and done to our satisfaction. Their customer service was great. They came back out to adjust a door that wasn't closing perfectly."

"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."

"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."

Customers say: Quick response

"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 Raritan, 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.
