"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 recently hired Bonus Home Remodeling to remodel our unfinished basement. Rob and his team were outstanding to work with from the onset of the project. They worked with us to make final design decisions, and throughout the entire project they had a large white board set up in the basement outlining a timeline of the projects so we always knew what was coming up next. They arrived at the same time everyday and left at the same time everyday which made it easy to live through such a big project taking place in your home. Rob and his team made everything convenient and easy for us. Any issues or questions that came up were addressed immediately and always ensured that we were happy before moving forward. The finished project is exactly what we were hoping for! It is gorgeous and the quality of the work is excellent."

"Joseph and Sons had done our waterproofing in our finish basement. What I liked about this company was, they were the only company to do waterproofing and finish our basement with Sheetrock, trim, trim and floors. A one stop company that does all. Always delt with Angelo and he was very knowledgeable. Will be using them for future jobs."

"Carmello is great. After a flood ruined my basement these guys completely repaired and renovated the space including new french drains, vinyl sheeting behind the drywall, dry locked the window wells and caulked all necessary gaps. Not cheap but they knew exactly what they were doing and since our area has had several storms w record rainfall and my basement has been bone dry. Would use them again in a heartbeat. Highly recommend."

"During the initial quote process Tom was very knowledgeable and put together a great plan for basement remodeling. My basement was transformed from the style of 50's to a modern basement that I can enjoy with my family. The staff was friendly and worked diligently 6 days a week without interrupting to my day. I received updates through the project from Tom on the progress. The company provided completive rates and this was the best money spent. I would highly recommend this company to anyone looking for quality work, your will not be disappointed."

"American Home Remodeling was absolutely stupendous to work with. I reside in Irvington and needed vinyl siding and 3 windows replaced to my home. Victor, Kelvin and their team of workers were efficient, service-oriented, and professional from the pre-planning stages- through the completion of the project. I highly recommend their services. Their work was clean, and gave my home a tremendous, refreshed look. A BIG thank you to Vic, Kelvin and the American Home Remodeling team. You guys are ROCKSTARS!!!!!"

"I hired Cesar and his crew to gut and renovate multiple bedrooms a kitchen and 2 bathrooms. Cesar, Armondo and Benjamin were an absolute pleasure to work with. Their knowledge, expertise and craftmanship are top notch. Cesar is easy to work with and truly cares about making sure his customers are happy. Cesar has an uncanny knack for finding a solution to any problem he encounters. I found his pricing to be very fair and reasonable and I quickly learned I could trust Cesar. If you are looking to remodel, finish off a room or repair any part of your interior, Cesar and his team should be your first call."

FAQs for basement remodeling projects in Denville, 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.
