"We needed some work done in our basement and needed the work done quickly. Called Harvey and the work was done in 3 days and at a fair price. They remodeled our home in the poconos in less than one month and we get so many compliments from our renters. We will definitely use their services again. Thanks Harvey!"

"They were easy to work with and the job came out great. After the basement remodel, we had them back to install bathroom and other cabinets. All went well, even with a different crew. Dave knows how to guide the customer to make good choices. Company is very dependable and prices are reasonable/competitive."

"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)."

"Arthur gave us a fair and competitive estimate and was able to start work quickly thereafter. He and his team did an excellent job gutting and totally remodeling two bathrooms and a closet as well as redoing some of the wood flooring, moving vents, and moving hallways. Arthur himself was at the home everyday and did the important work himself. He also went the extra mile in helping us with small projects around the major project as they came up. He was extremely responsive in provided us with timely updates. When complications occurred (due to the house having not been renovated in 40 years) he was clear and helpful in keeping the project on schedule. He was extremely honest and I trusted him to be alone in my house for weeks on end with his team. I would/plan to work with Arthur again in the future for my home renovation projects."

"Jeff & Crew came and did an amazing job just as they did when we had our whole basement remodeled. We hired Northgate this year once again (they remodeled and added a new bathroom to our basement back in February 2023) to redo and expand our outdoor deck to almost 1,000 square feet. Jeff and crew did an amazing job and went above and beyond. I cannot recommend or say enough about them. Jeff not only does an amazing job but added even extras that were unexpected and helped fix things that were not part of his job. I will definitely be hiring them again once I can afford more renovations! Would recommend Northgate to anyone and everyone."

"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."

"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."

"We hired LI Developers for a complete gut of our basement bathroom. They were always right on time, courteous and respectful. They coordinated all permits with the town, architects and outside contractors and provided professional opinions and input throughout the entire process. The end result was beautiful! We are very pleased and would highly recommend this company."

"Robert did an excellent job with our kitchen remodel (replaced all cabinets, countertops & backsplash). His quote was well below the others and more comprehensive. Added costs were kept to a minimum and explained in advance. All of his workers were courteous and professional."

Basement Remodel FAQs, answered by experts

In many homes, an unfinished basement is an ideal place for an in-ground pool. The concrete floors, protection against water damage, and access to the ground below your home make this a large contender. Speak with a local basement remodeling contractor to ensure your space is right for the large construction.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

A finished basement does not always count as square footage, as this varies by state regulations. In areas that allow below-grade spaces to be included in a home's official square footage, the basement must typically meet certain conditions. These conditions often include having a functional egress and being a livable space with flooring, finished walls, and temperature control. To be certain, contact your local assessor to confirm your area's specific policies regarding basement square footage.

Whether it’s more affordable to gut a house than build a new one depends on the markets where you'd be buying and selling. However, it’s usually less expensive to renovate a home than to build new construction. 

Most homeowners pay between $100,000 and $200,000 for demolition and remodeling costs, whereas the average cost to build a new home is between $139,000 and $531,300.

Efficient appliance positioning, optimizing existing plumbing, and sourcing energy-efficient materials reduce financial impact and increase sustainability.
