RW Contracting is a local owner operated business that has been in business for over 15 years. We specialize in basement conversions and bathroom remodeling. No job is too big or too small.

"We found RW Contracting through Home Advisors. Before we started we got a few estimates and we decided to go with them. They gave us a reasonable estimate (not the cheapest) but included more and Rich definitely had a great vision of what our finished basement could look like. Rich is a definite pro at finishing basements and so easy to work with! He suggested replacing old casement window and including some built-ins and half walls stuff that we weren't thinking about but I'm so glad these enhancements are part of our finished basement. Rich and his team were wonderful to work with. No concerns with them in the house alone. They were honest, clean, courteous and always on time. Rich personally managed the project from start to finish, he is extremely accountable. We are so happy with our finish basement and we give Rich the highest recommendation. You won't be disappointed, he is one of the best (and we are very particular)!"

"Hired Matthew Lin owner and operator of The Finish Guy LLC for a basement renovation. We had a detailed contract with a payment schedule . Matt requested a $25,000 deposit we gave it to He was trying to request another $20,000 by day number 4 of the job , going against his own contract . He never came to the job site and checked on his men . He wasn?t given us proper material that was promised in our contract trying to give us cheaper items then what we had outlined in our contract !! He forged my fiancé?s signature on the plumbing, electrical and fire permits, lying, putting all his contact information were is should be the homeowner info LIEING trying to say the homeowner was doing all their own work . I?m limited as to how many words I can write in this review ! Ultimately, we took them to court. He was ordered to pay us back $12,500 He defaulted on payment schedule. I had to put a lien against him."

"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."

"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."

FAQs for basement remodeling projects in Flemington, 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.
