"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."

"We couldn’t have replaced this door with a better expert. Ryan took measurements and photos, then recommended several doors in various price ranges. We didn’t realize how many options come with storm doors. Ryan gave us some really good recommendations and helped us make a great choice. He installed the door in a half day while we were out. Came back to a gorgeous door/screen storm door combo- something we weren’t even sure could have been done to begin with. Important to know:Throughout the entire process, Ryan was responsive and easy to reach. That’s vital in a world where ghosting is the norm (unfortunately). Ryan is the expert you need for your remodeling needs. Highly recommend!"

"We hired TQ Contracting to finish a portion of the basement. Tom and his crew, including Romeo, did a fantastic job and were very easy to work with. They were prompt, effective, and clean, and all inspections passed with flying colors. I was even comfortable letting them work in the basement during periods in which I was not home - this is a team you can trust. I could not be happier with how the basement turned out. Plus he quoted me a fair price that came in over $12K less than another quote I received from a different contractor. I was so stressed trying to find an honest, reasonable, and hard-working contractor and am so thrilled I went with TQ Contracting; the 5-star reviews you see online are 100% legit and they really do a terrific job!"

"I was in desperate need to replace my broilers because my heating system was not working as well as it should have been. Luckily American Home Remodeling are able to find me more efficient options at a reasonable price. They updated the entire heating system for all the floors of my house, updated all the electrical switches necessary and even included the clean up for the job. They handled all the permits necessary so my house was up to code as well. The entire job was done within a shorter period than I anticipated and they remained in contact with me throughout the entire process so I was aware of what was happening. I'm definitely going to use them in the near future when I finish my basement."

"Hired this company after interviewing two other companies to remodel my kitchen. My husband and I were saving for quite some years to have this project done so we wanted the best contractor that we trusted to do the work. They came in to our home (on time with the appointment) and explained every detail about the job step by step. We really appreciated this and we didn’t feel rushed or pressured. John the sales rep was willing to spend as much time needed to answer our questions. We did not get the same sense of patience from other contractors. Although not the cheapest or most expensive we are happy we selected Garden State Home Remodeling for our extensive kitchen rehab. Thank you Garden State Remodeling Group for a job well done."

"We had French drains installed along the perimeter of our basement. The contractor had a large enough crew to complete the project in a day. They cleaned up all of the debris and left the basement in great shape. We have had one very large rain storm since the work and the basement had no sign of any water entering the basement, a job well done."

FAQs for basement remodeling projects in Middlesex, 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.
