"We couldn’t be happier with the work that Jeff and his team did in our home! The craftsmanship is absolutely beautiful and the attention to detail really shows in every part of the project. From the custom built-ins around the fireplace to the perfectly finished trim and panel molding, everything looks perfect! The fireplace wall has completely transformed our living space.I have included before and after pics to show the beautiful transformation. The wainscoting in our dining room area also looks perfect, adding character and depth to what was previously a plain wall. Beyond the quality of the work, the entire experience was smooth and professional. Jeff and his team are very reliable and clearly take pride in what they do. They paid close attention to our vision while also offering helpful suggestions along the way. If you’re looking for someone who delivers high-end results with precision and care, I highly recommend them. We would absolutely work with them again! "

"Nick did an awesome job with our medicine cabinets. His work went above and beyond. When he noticed too-large gaps between the doors and frames, he drove all the way to the building supply store to get better-sized parts. Would definitely recommend him."

"Inson is a creative genius with a superb eye. He did everything with meticulous detail and completely transformed our apartment into an amazing, gorgeous home. We enjoy entertaining, and our friends love coming over, always remarking how beautiful and inviting our home is- and that was exactly what we wanted, except Inson brilliantly upgraded our concept, within budget and on time (even with our aggressive timeline because we needed to be out of our old place and into our new within months!). Inson’s team was also great to work with - always polite and professional. We highly recommend Inson and plan on working with him again on our Hamptons home!"

"I was looking for a contractor to renovate a 2BR rental property. After meeting with several contractors I had decided to go with HD Renovations. During the walkthrough BEFORE the work started, Dominick pointed out a few things and we came up with a plan for the project. Dominick and his crew showed up on time every day and worked non-stop until the project was completed. The work was excellent! When electrical and plumbing issues came up, Dom found a solution. He was a pleasure to work with. Always responsive to every question or idea. He had great suggestions along the way and really took pride in his work. The project lasted a month when others had taken 6-8weeks and stayed very close to budget even though I had made a few additions to the original proposal. As a landlord I have used many contractors over the years. HD Renovations were the best! I look forward to working with them in the future!"

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.
