"I have had several projects completed by Jakob and his company since buying my home in 2017. From little jobs to big jobs, Jakob is the only person I will trust with my home projects. His crew is reliable and hardworking. Jakob is hands on about EVERYTHING. From material orders placed, to deliveries, to getting permits, to scheduling inspections, to coordinating his crew for different jobs….. I honestly don’t know how he keeps it all running so smoothly. He built us a BEAUTIFUL paver/deck patio a few years ago, and this year he built us a STUNNING covered porch/portico with paver walkway which matches the backyard aesthetic. My neighbors have stopped to tell me how beautiful it is and they couldn’t believe how quickly it was finished. I very much appreciate how Jakob works with me to plan and make my vision come to life. He does the job well, and doesn’t cut corners. I feel confident and secure in his work, which is why he is the only person I will call when I need something done. "

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

With my years of experience we have mastered in becoming a pro in all interior renovations and specialized in door and frame installation for interior and exterior doors. Kitchen Installation with best outcome results and detailing and bathroom remodeling. Fully licensed and insured!!!

"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 Williston Park, 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.
