"No extensive renovation is easy to live with, but Scott and his crew made it as easy as possible. They are responsive and detail-oriented. They show up when they say they're coming and finish work within the time estimates--and the finished job looks great!"

"Jeff did a great job on our complete basement bathroom remodel last December so we asked him to do a small job of installing a vanity. The job was done quickly and efficiently. The price was reasonable. Everything was cleaned up. I highly recommend Northgate Home Improvement and will gladly hire them in the future."

"The owner and his crew was professional and courteous and most of all very clean. Mr. Lionel took care of small projects such as replacing door hinges which was not on the list. I would recommend him to anyone who needs work done at their house. Looking forward to hiring this company again to complete drywall in other rooms. Sign "Rosie""

"If you are in need of a professional with vision and integrity, Robert is the only one to hire. After a basement flood, we interviewed 3 other companies, all of whom wanted an exorbitant amount for the project and also wanted to charge for a written estimate. Reliable, knowledgeable on all matters of construction, mindful my budget and a true professional. His work is meticulous and he leaves your home spotless every day. I got lucky and so will you!"

"My wife and I had a very positive experience working with LI Developers. The remodeling was on point and fast. We needed the basement and bathroom remodeled so from start to finish, they were professional and courteous. Their prices are very reasonable and their estimate was MUCH LESS than other places we looked at. Their business practices are completely transparent and professional which was very refreshing. Ryan and Jakob were very helpful out at our the home end. They were professional, courteous and took a lot of care with their work and in keeping our home clean in the process. I was particularly impressed with how he completely covered the area around the work space, and kept our home super clean and livable while the work was happening. I would definitely recommend this company to anyone who needs to have work done in their home!"

"Efren Nunez made what could have been a stressful experience almost pleasant! My new (yet to be moved into) co-op apartment needed the work completed within a week and Efren worked hard to accommodate and meet the deadline. The ceilings and apartment look great. The crew left the place spotless. Very professional."

"Kenny and his crew came to our rescue after a prior contractor turned our renovation into a horror show. He fixed the tile work, the kitchen, two bathrooms, attic work and got our all wood floors to take on new decades of life. I can't say enough about the quality and attention to detail from his people... I spoke with them about what we needed and it was done perfectly... by people who had been with him forever it seemed. It's a wonderful company and my wife and I recommend them without reservation."

FAQs for basement remodeling projects in Valley Stream, 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.
