"I hired Bob for our basement remodeling project and thatâ s the best decision we took. He is such a perfectionist with his job, gives right suggestions on what needs to be done, not at all money minded, and mainly manages work to be on time. He returned back to work immediately after his surgery just to meet the deadline. We are more than happy with the outcome. I sincerely recommend Bob for any work he is capable of doing and worth the decision. In fact, I kept pinging him for more suggestions even after the job is done and he is very responsive. So thankful that we were able to find Bob through my friend and he is a highly recommended person for any remodeling job."

"The bathroom remodel was done beautifully. Anthony & his crew were very professional. Arrived on time everyday & put in a full day. I noticed he even was concerned about making sure everything was clean when leaving each day. His price was reasonable & we are going hire him 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."

"Hired Greg for a full gut and remodel of a bathroom. Greg was very competent, personable, and took the time to understand exactly what we wanted. He made us feel like we were in good hands. 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!"

"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."

FAQs for basement remodeling projects in Saint James, 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.
