"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 was recently had a complete bathroom renovation, and my family and I absolutely thrilled with the results. From the initial quote to the final walkthrough, they were professional, punctual, and meticulous with their craftsmanship. The team arrived on time every day, kept a clean workspace, and managed the project timeline perfectly, finishing right on schedule. They listened to my design ideas and provided valuable input that improved the functionality of our space. Their attention to detail on the tiling, electrical, and plumbing work was outstanding!

"Aldo and his team are extremely professional and respectful. He gave a fair price and did an amazing job. He always comes on time, and cleans up after work. I can’t say enough good this about him and his work and I would recommend him 100%. He’s done everything from plumbing, electrical, drywall and tiles. I hired him to install a kitchen backdrop and rehired him for multiple projects. Just recently he finished installing a new shower stall, vanity, lighting and bathroom floor. He also installed new lighting and replaced the basement drop ceiling with drywall. "

"I have had several projects completed by Jakob and his company since buying my home in 2017. From little jobs to big jobs, Jakob is the only person I will trust with my home projects. His crew is reliable and hardworking. Jakob is hands on about EVERYTHING. From material orders placed, to deliveries, to getting permits, to scheduling inspections, to coordinating his crew for different jobs….. I honestly don’t know how he keeps it all running so smoothly. He built us a BEAUTIFUL paver/deck patio a few years ago, and this year he built us a STUNNING covered porch/portico with paver walkway which matches the backyard aesthetic. My neighbors have stopped to tell me how beautiful it is and they couldn’t believe how quickly it was finished. I very much appreciate how Jakob works with me to plan and make my vision come to life. He does the job well, and doesn’t cut corners. I feel confident and secure in his work, which is why he is the only person I will call when I need something done. "

"I had an absolutely wonderful first-time experience with the crew at Home Innovation. They transformed my dated bathroom by removing the tub and creating a spacious, modern shower with stunning, manually installed ceramic tiling and elegant glass doors. The craftsmanship and attention to detail were exceptional. I was especially impressed with their incredible set-up and clean-up. They left everything spotless and perfectly finished. The entire process was smooth and professional.. I have been using their services for other house projects for the last two years and they never disappoint I The professionalism of this team is beyond incredible. I would highly recommend Home Innovation!"

"Interior Sources did an outstanding job on our bathroom renovation. They delivered on every promise they made. They showed up on time every day and worked consistently until the job was completed. The quality of the work is beautiful and we could not be happier with our new bathroom. It was truly a pleasure working with them and their entire team. I especially want to commend them for how professional and respectful they were throughout the project. They were easy to work with, kept everything organized, and treated our home with great care.

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.
