"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."

"BMR BelMax Remodeling completed a very large project for me that involved partial remodeling of 2 bathrooms, new flooring in bathrooms, kitchen, hallway and the master bedroom and staircase remodeling from carpet to wood. The crew led by Ivan completed the job in record time with good results."

"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."

"ImproveRite Home Remodeling was recommended to me by multiple people. We reached out and got a response from Robert pretty much immediately! He scheduled a consult just a few days later and we were able to get started within just a few weeks of signing our contract! Robert, Liam, and the entire team are extremely friendly, always prompt, and worked 6 days a week on our bathroom remodel. All of our questions were answered, they gave us their professional opinions on the layout and design options, and let us know if something would work or not. At the end of each day, the job was clean. When the remodel was complete, they sent a cleaning crew to the house who made everything spotless! If you need any type of home remodel, ImproveRite are your guys!"

Overall, Jesse and his team were wonderful to work with.  They were all very respectful and nice.  The team tried to leave as much as the wiring and the floor as possible, as not to demo everything.  In the demolition process, however, some of the screws for the light fixtures went missing (not a terrible thing, but a small hassle).  The whole process took about a week, and the drain and the walls were fixed.  Our house doesn't smell moldy anymore which is a great plus!  Two small things which bothered me slightly after the fact, was that the foreman, Bryan, said he would return a window insert for our basement window, which he hasn't done yet (it keeps air from entering the basement).  Also, instead of unscrewing some piping around the dryer vent, it seems that they have just ripped it out (but that was an easy fix on our end...we just got a new aluminum pipe for the dryer).

The team put plastic sheeting down to protect the furniture on the first floor where they had to come in and out of to get to the basement (we don't have basement access).  They also did a cursory cleaning before they left each day, which I appreciated.  It wasn't a deep clean, but that wasn't expected either. 

Jesse offered, kindly, to help us find some contractors who could help replace the drywall/studs and retile our floor; however, his contacts were all busy and weren't able to help us.  We ended up contacting some contractors through Angie's list to help us return our basement to its finished self. 

It has been about a week and half after the work was completed, and the system seems to be working (and we have had some crazy rain storms).  Although there is a puddle of water that collects around the lid of the sump pump, which worries me slightly.  I have called Jesse to ask him if that's normal, but otherwise the work was well done!

"I had contacted other contractors and handymen to have this work done. Some were way too expensive,   others didn't want the job, or said I lived too far away.  I was able to get David in person on the first call. I told  him what I wanted done and he made an appointment to meet me on a specific date.  He kept me informed every step of the way.
The window matched my existing windows perfectly. David had it installed in an hour during a heavy rainfall!   
I was very happy with the end results! I wouldn't hesitate to use Nilsen Building and Remodeling LLC again for other projects!

"All went well except for one misunderstanding, which I covered with another subcontractor. Project, as finished, is/will be almost completely invisible, which they went out of their way to help me accomplish. Very happy with price and job. And, most important, my basement is now dry!"

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.
