"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."

"My husband and I are beyond grateful to All-Star contractors for doing an excellent job on finishing/remodelling our basement. We never imagined that our basement will look this good despite the small size (we live in a townhome). Every space was made functional. Bill (the contractor) is very fair, always listen and give recommendations as needed. The price is appropriate for the excellent work done. Bill's crew is very hardworking and takes pride in his work - making sure that we will be pleased and always asked if there is anything or issue that needs to be addressed. We are in the process of lining up our next project with Bill. We will definitely not settle for another company for any work we need whether it is something minor or major. If you are looking for someone trustworthy - we will definitely recommend Bill without a doubt."

"We hired JK Custom Building to demo our 1950's finished basement, bathroom and replace our basement windows. This was a project which we had been putting off for years. In the end we were amazed how quickly the job was completed and are very happy with the results. JK Builders is a professionally run company that is dedicated to delivering complete customer satisfaction. We would highly recommend them to anyone."

"They did an excellent and clean job. The price is awesooome!!! I started by doing the ceiling and ended up remodeling other places in my home. I gave the contact information to my office maintenance manager and he was delighted with the work they did on the ceiling at my job."

"We had Good Deal Remodeling complete a remodeling in our small master bathroom. Bogdan, Nicholai, and their team were great to work with. They were quick to provide responses for our initial quotes, and then the final pricing. They finished the job much faster than expected, and they were able to work around some delays that we had in receiving some of our materials that we had ordered on our own. The final job was spectacular, and we are enjoying our upgraded bathroom. We would highly recommend their team to anyone looking to remodel their home."

"Dominick recently replaced all of our floors with hardwoods and tiled out our laundry room. Took a little bit to get going but well worth the patience. I'm amazed every time I walk into my house and I literally go room to room just to look at them. I am beyond picky and decided this needed a professional to get done right. Dominick and his crew couldn't have been more perfect with their quality and respect for our home as we had to live amongst the chaos. I would highly recommend D & J to anyone whom needs a great contractor."

FAQs for basement remodeling projects in Lambertville, 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.
