"If you are in need of a professional with vision and integrity, Robert is the only one to hire. After a basement flood, we interviewed 3 other companies, all of whom wanted an exorbitant amount for the project and also wanted to charge for a written estimate. Reliable, knowledgeable on all matters of construction, mindful my budget and a true professional. His work is meticulous and he leaves your home spotless every day. I got lucky and so will you!"

"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."

"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 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."

"After my family and I decided to move back to the old Queens house I grew up in to live above my mom, we quickly realized there were many things that needed to be repaired. I've counted on Nunez Construction and Painting for all of it. The first job they did was to repair some siding on the house. Prior to our move, we then wanted to gut and remodel the second floor apartment where we live. Mr. Nunez and his crew did a great job. More recently, our basement became flooded with sewage. We called him again to help with this project and install a new floor. We are always very satisfied customers. The work is great and reasonably priced. We can't thank him enough for being a wonderful person and company to work with."

Customers say: True professional

"We live in a prewar coop building in Manhattan and were in need of a kitchen, living and dining room/den renovation. Because of the limitations in our building, we were not optimistic that many changes could be made that would dramatically alter the feel/function of the space. Inson Wood proved us completely wrong. With his architectural eye and his impeccable design aesthetic we (and everyone who has been here before and after) experiences our apartment as an entirely different living space. Even family members are shocked at the transformation. I think that what Inson accomplished was the product of a few significant factors. First, Inson asks you what you want and seriously considers how you live. If Inson thinks that different approaches should be considered for what you want, he provides renderings of each option so that you can easily visualize and imagine them. Ultimately, Inson respects your preferences and works with them, elevating them to a level far above what you had imagined. Inson uses the highest quality vendors (whom we NEVER would have found) and expertly guides you through choices (note: follow his recommendations!!!)- our walls would never have had dimension and our kitchen backsplash never have been so unique (two examples) if not for the artisans that Inson uses. Inson is also willing to have you be as much or as little involved in the process as you want to be. I did go with Inson to choose many pieces of furniture but realized after a certain point that his taste point made me confident in him choosing much finishing work (ex: window treatments, decorative cushions, which I love) without me. As with all design work, there are always glitches and Inson was extremely responsive and responsible for taking care of those as they came up. We are nothing less than thrilled to come home each evening and enjoy our space, which feels like a luxurious retreat perfectly tailored to us."

FAQs for basement remodeling projects in Port Washington, 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.
