"I have had Jeff and his guys renovate my ranch house in Melville. He has done 2 bathrooms, my basement and my kitchen. He has always been reliable and done great work. The house looks like new. He quickly corrects any problems and is always in touch. He and his guys are friendly and neat. His estimates are reasonable. I strongly recommend Northgate Home Improvement."

"I can’t recommend Stars and Stripes highly enough for anyone considering a home renovation. From big projects like installing new countertops and a backsplash to smaller details like fixing the track on my sliding closet doors, everything was completed with exceptional care and attention to detail. What really sets them apart, though, is the trust factor. I’m not someone who’s usually comfortable leaving people alone in my home—but with Stars and Stripes, I never once had to worry. They were respectful, reliable, and I always felt my home was in good hands. It's rare to find that kind of peace of mind with contractors, and it's what will keep me coming back for future projects."

"My experience with Nick was A++ from start to finish. When we first met, he took the time to understand my project and needs and to review options. He clearly cared a lot about his work and creating a special space for my family to enjoy in our home. His prices were reasonable (I got several estimates) and he stuck perfectly to the budget we agreed to. The finished product is even more beautiful than I had envisioned, it’s perfectly finished and created a great usable space in our home. 100% would recommend Nick for any and all construction work! "

"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."

"contacted Gus for recent roof leak; he was here the same day. He first went into attic space (while there he replaced a burned-out light bulb) to check location of leak, took photos, had me view them; then went on the roof. He located popped nails, which he removed and sealed. Took photo of that as well as surrounding area which he also sealed with a product called, through the roof. He came down and told me the roof vent required a cap and said he would return to install it. Once he installed cap, he also took the opportunity to blow the leaves from the gutter. Once on the ground, he proceeded to blow leaves and debris from front and back walkways."

FAQs for basement remodeling projects in Lake Grove, 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.
