"For the very best value in home improvement construction, I recommend Roberts Remodeling because when you hire Robert Remodeling you get much more than just a contractor; from Planning to Design, to Supplier Negotiations, to Over Seeing Every Detail of the project, Robert delivers VALUE!! His experience, his special ability to recognize great design and complete difficult projects makes him the best choice! I chose Robert for my condo in Long Beach 13 years ago, and then this year 2020 he remodeled my new old home in Island Park with the same high quality, dedication, and skill! No reason to hire anyone else!!! My experience with Robert is not unique, I have referred him to many neighbors, friends, and relatives and they all have the same experience and reaction - they all loved the workmanship and VALUE!!!"

"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."

"Domenick did a great job of refinishing my cabinets and making them look brand new. The specialized refinishing paint for the cabinets was odorless. He replaced all the hardware and the job was done in approximately 4 days. He also did a beautiful job painting the entire interior of my home. My house looks fresh and new. The painting of my home took about one week. He also did other tasks, replaced an Air Conditioner in the bedroom, put together 2 pieces of furniture from Wayfair, cleared the gutters outside my home. He is pleasant, honest, reliable and a pleasure to do business with."

"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!"

"I used these guys for a remodeling job which included bathroom renovation, some minor electrical work, knocking down and installing new dry wall and painting. Class acts! We all hear horror stories about contractors not calling you back or not showing up on time or showing up at all. Not these guys! Hector, Moises and their crew really did exactly what they said they were going to do. Friendly, responsive and oh yea, solid work! Professional through and through! Highly recommend them and would use them again!"

FAQs for basement remodeling projects in Syosset, 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.
