"We hired Scott on the advice of the architects we worked with on this project. Scott and his team were always friendly and professional (including no loud cursing while working, which was refreshing!), and they always arrived on time. The project presented many challenges, many of which pertained to the hatch fabricator. Scott handled much of the correspondence with the fabricator, including dealing with manufacturing errors. He always worked with us to make sure our problems were solved, which meant coming back repeatedly to work on lingering issues. While substantial completion of the project was done on time, it did take longer than we anticipated to finish everything. All things considered, it was a positive experience and we're happy with the results. We would recommend Scott to friends."

"Robert is a trustworthy and skilled professional. Our family has engaged his services on multiple occasions -- most recently to install flooring in our basement -- and plan to do so in the future for additional remodeling work. Robert and team are reliable and perform great work (at a great value)."

"I hired Jakob and LI developers to remodel my Kitchen and first floor bathroom. Jakob was attentive to my wishes and very detail oriented. His crew showed up everyday ready to work and the time of the turn around was great as I still needed to live in the house. Beautiful work and Jakob was always there either over the phone or in person when I needed anything. Great outcome overall highly recommend."

"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""

"Anderson is a miracle worker, installing a shower in our basement bathroom when other contractors said it couldn’t be done or would be outrageously expensive. Anderson did the work in a short time, cleaned up all the debris and left it spotless. His cost was very reasonable and he used his contractor’s discounts for the materials. He communicates very well so I knew when he was coming and going. I was consulted at every step. I highly recommend Home Innovation!!!"

"I first asked Jeff at Northgate to take out our old basement bathroom and build a new one 4 years ago. He did a great job for a reasonable price. He recently completed a total basement renovation and upstairs bathroom. Everything down to the studs. Again, did a wonderful job in about a month. He really deserves all the excellent reviews he has had. He always keeps you in touch and fixes any problems right away. We will be happy to have him do our kitchen soon. You will not find anyone better."

"Dominick did an excellent job on my project, which was to scrape our bathroom ceiling, do some light replastering, and prime and paint with a special anti-mold paint. He and his assistant arrived on time both days, took great care to protect our floors and bathroom, and even vacuumed our ceiling vent for us. His prices are on the high side, but we're thrilled with the result and would work with him again."

"I hired Metropolitan Paint to build bookcases with library lighting, a hidden pantry closet, install new bathroom fixtures & paint. Their work was outstanding. Kenny checked in on the project daily, everyone showed when they said they were going to show up, they stayed on schedule and - most importantly - my Superintendent made a point of telling me how impressed he was with everyone's professionalism and will be recommending them for future projects in the building. No easy feat for a persnickety UES building that can try the patience of the kindest souls. I would absolutely recommend Metropolitan Paint to anyone for any job."

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.
