"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."

"Retrofix Construction did an outstanding job finishing our basement. The workmanship was excellent, from the flooring and drywall to the painting and trim. The team was professional, kept the work area clean, and completed the project on schedule. The basement now feels like a bright, comfortable living space. We highly recommend Retrofix Construction!"

"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)."

He took the time to make sure things were done the right way. The result was top notch, couldn't have asked for more. I would definitely use this company again!"

"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."

"Metropolitan Painting & Contracting painted my apartment, which included wallpaper removal, skim coating, baseboard replacement and painting. The quality of the work was excellent, the walls being very flat and lines straight. They started on the date planned and completed the project within the time estimate. Mr. G and his crew were very courteous, protected my floor and non-painted surfaces (wood, brick, bookcase), and worked with me to get the details right. Baseboard work and crown moulding work by carpenter Fernando was highest quality, being very straight and adjusting to floor height. I would hire Metropolitan again for my next project."

FAQs for basement remodeling projects in Oyster Bay, 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.
