"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""

"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!"

"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."

"Working with Tom and his crew was a fantastic experience. He and his crew finished my basement and installed new flooring on the main level in just a few weeks. We were given progress updates everyday. We would definitely use Summit again!"

"Stone’s Construction did the siding and gutters and leaders on our house this past July. We were pleased with his price and his work. His crew was very professional and easy to work with. Bill made certain to address all of my concerns and made sure that I was happy with the work. He would check in regularly and was very quick to return my calls. I highly recommend Bill Stone and his crew."

"I hired Long Island handyman construction group to remodel a 400sf basement and bathroom in Melville. They were priced in the middle compared to other bids. I picked them thanks to their out of the box advice which saved me thousands of dollars. There was one problem with the plumbing which cost an extra 1800 dollars. The owner settled with me 50/50 even though it was a pre-existing issue. The project was started early and completed early. All mess was cleaned up and the crew was very friendly and fully aware. Very reputable guys and very easy to deal with. Thanks Moises and Eddy."

"I recently hired Jakob and his team to remodel 2 bathrooms and they did a wonderful job. I found them to be very professional and courteous. They made sure to protect all areas of my house especially during the demolition phase. Jakob was especially helpful in the design phase and assisted me in selecting the tiles, fixtures ect to make the bathrooms look and function wonderfully. I will be reaching out to them for future projects and I highly recommend them."

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.
