"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."

FAQs for basement remodeling projects in Commack, 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.
