"Tom and his crew did a beautiful job. Everything was done professionally and showed great attention to detail. I highly recommend TQ Contracting. The bathroom came out better than I envisioned."

"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."

"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."

"Contacted Sky's the Limit to patch/repair/paint an older addition. He exceeded our expectations. The work was exceptional, his crew was clean and neat and they completed on time and on budget as promised. Could not be happier with Adrian and his team. It's rare to find an honest contractor these days. Will definitely be recommending him."

"A positive experience all around! My first renovation, I was unclear about many aspects of the contracting process, let alone the actual work that needed to be done. Ryan is an excellent communicator--a fact clear from his first visit and which helped us choose him for the job--and I felt at ease throughout the project, always on top of what was going on in my house, and able to make informed decisions along the way. Indigo delivered exactly as promised, reliably on schedule. Ryan and all his crew seemed to work efficiently and tirelessly, and were always polite and respectful of our property and privacy, in what was at times a crowded little house. We got a price we consider fair, and know was competitive. And we are very happy with the new bathroom. Looks great!"

"If I could give them 10 stars I would. I had Garden State Home Remodeling come to pave my old torn up driveway and yard space and replace with asphalt. This was my first major home project and I was really nervous. Kelvin walked me thru the entire process from beginning to end. Kelvin was so professional and answered every question I had. Everything I asked for was done over and beyond. The crew did an excellent job on my driveway/yard. I’m more than happy and will use their services again!"

"Nick, Apelles Construction, provided a detailed estimate for the complete renovation of our 3 bedroom, 2 1/2 bath house. The work primarily consisted of a new kitchen, new baths, hardwood floors, and painting. Apelles completed the work within the six week timeframe that was promised. They also did some and work along the way. Nick, is a very talented contractor. He is also creative. Nick planned and approached his work in an organized manner and demonstrated a superb talent - that we were not expecting. Nick and his crew were conscientious, neat, and organized. They always demonstrated a pleasant demeanor."

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.
