"We got an estimate from Robert Remodeling back in March of 2021 for a complete basement renovation. At that time we also pursued additional estimates from well-known and recommended contractors. We were simultaneously getting estimates from siding companies for our entire home and 2 garages. From our first meeting with Rob, we knew that he was the man for BOTH jobs. He continued to meet with us at least 3 more times before his start date on 9/21. During these meetings, Rob reviewed potential problems as well as made sensible and affordable design recommendations aligned with our vision for the space and our family needs. This was the first major home renovation for us since owning our home and we needed someone knowledgeable, skilled, patient, loyal, dog-friendly and most importantly, someone who valued our money and how/where it was spent as much as we did. Rob delivered on all accounts! We can honestly say that he went ABOVE and beyond from day 1. Rob and his crew fully gutted our basement, installed a gorgeous kitchen, renovated a bathroom, and installed new flooring throughout the space. Our basement is now a show stopper! Not only did his work increase our home overall value, it also increased our living space and we will benefit from the skilled workmanship and smart choices he made along the way with our family in mind for years to come. We undoubtedly made the right choice when we hired his company and, without knowing it, also made a great friend. His work ethic and meticulous nature are very rare gems in the construction industry. Do yourself and your hard-earned money a favor and give him a call!"

"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!"

"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""

"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!"

"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."

"All of the work was done professionally and with great attention to detail. The owner “Dominick” was present each day and discussed any questions or concerns regarding this project. His two assistants were also very thorough. At the end of each day, the work area was swept and vacuumed. I was 100% satisfied. I would definitely use the services of this company again."

FAQs for basement remodeling projects in Rockville Centre, 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.
