"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 first asked Jeff at Northgate to take out our old basement bathroom and build a new one 4 years ago. He did a great job for a reasonable price. He recently completed a total basement renovation and upstairs bathroom. Everything down to the studs. Again, did a wonderful job in about a month. He really deserves all the excellent reviews he has had. He always keeps you in touch and fixes any problems right away. We will be happy to have him do our kitchen soon. You will not find anyone better."

"I was extremely happy with this company. I liked the fact that he would come to install one door. (Good to his advertisement, he goes to Suffolk county) It turned out to be more than the one door.. He returned my call, the same day. I found Greg, a pleasure to deal with. I chose his company to call, over 3 other names I felt fortunate, it worked out so well, and I made an excellent choice. Now have the name of someone who handles all types of home repairs, that does excellent work. I was extremely impressed, that upon walking up to my door, he removed the snow, off the steps. Top notch company!"

"Dominick did an excellent job on my project, which was to scrape our bathroom ceiling, do some light replastering, and prime and paint with a special anti-mold paint. He and his assistant arrived on time both days, took great care to protect our floors and bathroom, and even vacuumed our ceiling vent for us. His prices are on the high side, but we're thrilled with the result and would work with him again."

"Review Hampton Design and Build inc Restored our house to its former luster after a pipe burst causing major damage to our main floor and basement. Dale and Diane worked tirelessly on our behalf to replace sheetrock insulation, repair the heating plumbing and electricity. They oversaw the rebuilding of our kitchen and laundry room with new cabinetry and countertops, replaced our beautiful wood floors in the common living area as well as replaced the basement carpeting with core-tech. Diane was very helpful with kitchen design and interior decorating which updated our house. Dale and Diane were easy to work with-consulting with us, keeping us informed and taking care of all the details. Dale guided us through the entire process as we would not have known where to begin therefore we would highly recommend using Dale and Diane at Hampton Design and Build Inc."

FAQs for basement remodeling projects in Southampton, 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.
