"RUN. Con-artists. We paid them $76,000, they completed $60,000 worth of work per THEIR itemized invoice, did not properly secure the site leading to $5000 of water damage to my existing house that they did not repair, shoddy work and crooked doorways and windows that had to be redone by another contractor, did not pay the foundation guy in full, did not pay the lumber company leaving us with mechanic’s liens on our house that we had to prove we paid ACC and it was THEM not paying their bills… I could go on.

"We recently completed a home addition project with Frank, and the experience was outstanding from start to finish. The work included a particularly complex installation of a steel support beam, and Frank handled it with absolute precision and skill. His attention to detail and commitment to meticulous quality were evident every step of the way. What really set Frank apart was his transparency and communication. He kept us updated daily, explaining the process clearly and making sure there were no surprises along the way. He showed up every day, worked consistently, and delivered the project on time. The pricing was more than fair given the scope and quality of the work, and we always felt we were getting exceptional value. We couldn’t be more pleased with the final result, and we would hire Frank again without hesitation. His professionalism, craftsmanship, and reliability make him a contractor we recommend wholeheartedly."

FAQs for basement remodeling projects in Nassau, NY

While the terms remodeling, renovating, and finishing are often used interchangeably, there are some differences. Remodeling your basement transforms the space by changing its layout, adding new features, or altering its function. Renovating restores the existing space to like-new condition without major structural changes. Finishing converts an unfinished basement into a livable area with walls, ceilings, and flooring.

A full basement remodel typically takes two to six weeks, depending on the project's complexity and any unforeseen challenges. Factors like design changes, permitting, and material availability can affect the timeline, as well as the availability of the contractors you’re working with. Remember that the bigger the project, the longer it will take to complete.

Remodeling your basement is not just about gaining extra space—it's a savvy investment. You can expect around a 70% return on investment (ROI), comparable to other major home improvements like kitchen or bathroom remodels. Adding functional living space boosts your home's value and appeals to potential buyers. Plus, converting your basement into a rental apartment could provide additional income, increasing your return even more.
