"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."

"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."

"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!"

"We have worked with Anthony from TAS Construction since 2006. He built a 2nd story addition on our home and completely remodeled the first floor. His work and crew are professional and courteous and you see right away that Anthony cares about his clients. After Hurricane Sandy destroyed the 1st floor of our home, Anthony was there to help us repair the water damage almost immediately. Fast forward to August 2020, and Anthony made time to give us an estimate for some recent storm damage in a few hours. He knows his stuff and has a great eye and ideas that look amazing when implemented. We constantly get compliments on our home and never hesitate to recommend him ."

FAQs for basement remodeling projects in Bethpage, 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.
