"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 are currently happy with the basement waterproofing and remodeling that was completed! There were issues - most minor but we haven't anything to compare as this was the first-time having contractors complete basement work for us; and our home is almost 100 years old. They were flexible given unexpected issues that came about with the basement. The water proofing was done first and they did a great job. They were happy to review and resolve any remaining questions/concerns and/or issues. Jorge in the service dept. is professional, punctual and is a great representative and asset for this company."

"My husband and I are new homeowners in Yardley; we interviewed 10+ contractors in the area to complete a basement remodel at our home. Renovations can be scary and we were very adamant about choosing the right partner for the project. We are so glad that we chose Improverite! Robert and his team are truly the best in the industry! Robert is a high-energy, passionate professional who made sure we had a first-class experience. Every part of this process exceeded our expectations. He was diligent about earning our business and building our trust. I really can't put into words how good his team is! Everyday I was blown away at the progress and craftsmanship of their work. I was not expecting that level of talent and customization to go into the project. We have a space that is above and beyond anything we were expecting and could not be happier and pricing was very competitive! The gentlemen at Improverite are thoughtful, professional, and incredibly skilled at their work. We highly recommend them and will absolutely use them for our next home project!"

"I needed to sell my home in New Jersey after being offered a relocation to the West Coast. We had an 80 year old house and needed to have the entire porch torn down and re-built. Dominick came in and personally did the demolition (including jackhammering the concrete steps) and put in a beautiful wood porch. It was attractive, strong AND fit the style of the house perfectly. The best part though, was that I was able to focus on packing up our home and preparing my family for our big move. It was such a relief to have a true professional manage this project so that I could focus on my family. I recommend Dominick for any contruction/masonry work you might have."

"Greg did an amazing job while working with old fairly shoddy construction with the building we were in. He was able to save and fix an outdoor plug we were sure we’d have to just rip out entirely while bringing everything up to code and safety standards with the town. Everything was super easy and incredibly chill. If you need work done I can’t reccomended him enough. Greg really goes out of the way to get things done."

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.
