"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!"

"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 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!"

"Handy Dominick is very experienced and professional contractor. I had an old apartment and he renovated the apartment from scratch. I was so pleased with the quality and timing of the job. He was very clean, organized, on time. He is such an honest and true person always suggesting the best for the outstanding outcome of the job. The price he charged me was average to high but very worth it for the quality of results he provided. Dominick completed the job on the same time frame he quoted. He is very punctual and precise with his work. I highly recommend Dominick and his crew."

"TrueCraft Construction Group remodeled our bathroom in Fresh Meadows and did an incredible job. Rob is very knowledgeable and takes the time to explain everything, which made us feel comfortable from the start. The tile work, fixtures, and finishing details were all done perfectly. The space looks clean, modern, and well-built. Great experience overall. I would definitely recommend them for bathroom remodeling and interior renovations in Queens."

FAQs for basement remodeling projects in Old 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.
