"We couldn’t be happier with the work that Jeff and his team did in our home! The craftsmanship is absolutely beautiful and the attention to detail really shows in every part of the project. From the custom built-ins around the fireplace to the perfectly finished trim and panel molding, everything looks perfect! The fireplace wall has completely transformed our living space.I have included before and after pics to show the beautiful transformation. The wainscoting in our dining room area also looks perfect, adding character and depth to what was previously a plain wall. Beyond the quality of the work, the entire experience was smooth and professional. Jeff and his team are very reliable and clearly take pride in what they do. They paid close attention to our vision while also offering helpful suggestions along the way. If you’re looking for someone who delivers high-end results with precision and care, I highly recommend them. We would absolutely work with them again! "

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"Originally, I had a great review because the finished work looked great and when I was able to, I didn't see any shortcuts as the team that was hired by the contractor (Mohamed) was there during the week while I was at work. It was good...contracts signed and lifetime warranty was signed of the life of the work. Who wouldn't be happy. Just 2-3 months after the project was completed, problems started to occur. The shower items had minor low flow because of the water that was coming in from the street. They came. Then the handle that held up the shower hand device malfunctioned, the toilet installed was having sealing issues, and the sliding door for the shower was jamming. It took some time for them to look into the issue but when they came, they patched the shower device or seal (later to find out, it was just in drywall with a wood screw on no wood), told me they won't fix the toilet, and shifted and patched the sliding door. I had to get these fixed on my own then the ceiling light they installed doesn't work. I will have to get this fix on my own. I am very disappointed as they gave me all smiles until the last payment then after it was like them visiting to fix the issues was a problem. Again, the problems start in under 3 months. Let me not start on the kitchen. All I have to say is if your were going to take shortcuts and use crappy material, why waste each others time. I have photos of all the problems as well as the contractor."

"Inson is a creative genius with a superb eye. He did everything with meticulous detail and completely transformed our apartment into an amazing, gorgeous home. We enjoy entertaining, and our friends love coming over, always remarking how beautiful and inviting our home is- and that was exactly what we wanted, except Inson brilliantly upgraded our concept, within budget and on time (even with our aggressive timeline because we needed to be out of our old place and into our new within months!). Inson’s team was also great to work with - always polite and professional. We highly recommend Inson and plan on working with him again on our Hamptons home!"

FAQs for basement remodeling projects in Uniondale, NY

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.
