"I have had Jeff and his guys renovate my ranch house in Melville. He has done 2 bathrooms, my basement and my kitchen. He has always been reliable and done great work. The house looks like new. He quickly corrects any problems and is always in touch. He and his guys are friendly and neat. His estimates are reasonable. I strongly recommend Northgate Home Improvement."

"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!"

"First, when I asked Tyler for a copy of the contract I signed, he said no. I see that as strange. I asked again and took it and made a copy for myself. I am glad I did. Beware of this. He gives no warranty. Read the contract carefully. It covers him and not you. He told me 1 week for the bathroom. It took 3 weeks. Before Tyler came to pick up his payment today he texted me the following - Fan $400 and window casing $350. Total $7750 very good price with that tile you picked I thought the wall tile was 12x12 when I saw the box normally that tile would cost much much more to lay it took extra two days so any tip would be greatly appreciated thank you ð ð ¼ So let me explain, we agreed on contract for $7,500 for a bathroom remodel with me buying my own materials. Installation of vent included in scope of work. He charged me $400 for a vent fan which costs $119.00 at Lowes. This is dishonesty. I showed him the price for vent fan and the contract where vent installation is included. He told my husband he will cased a window and placed molding in bath which he said would be easier work for him rather than sparkle, drying and sanding takes longer and more work. Then he wants to charge me additional for molding. He forgot sparkle and sanding included in contract ($7,500) and he is replacing that for his convenience with molding. It is like paying twice for the same thing. He did no work orders and discussed no pricing for any of this earlier with me. He only told me the vent fan would cost $108.00 earlier and I told him to pick it up for us. Today, he inflated prices, and gave me a final bill as seen above. His tile guy worked one and a half day on the tile installation on bath wall. They flooded my kitchen ceiling and I spent one half day repainting it at my own cost. What about my labor? He parked his huge garbage dumpster and tool truck in my driveway for days one after the other and I parked 4 vehicles in the street. He does not care about what he did to the homeowner. Your time lost and sacrifices do not count. Do not inflate prices on people. Not good business. Be honest."

"Artie & Mike are simply the best. I used them to: 1) Build a LARGE extension to my house and redo my entire kitchen and dining room. The job was completed on time and on budget. Throughout the process Artie was transparent & professional. EVERY person who has stepped into my house has complimented at the detailed perfection. 3) Artie built us a custom walk in pantry 2) Built 2 large decks in the backyard as well as an outdoor shower. This project was completed on time, on budget while exceeding all expectations. If you are looking for a contractor and crew that is responsible, responsive, polite, creative and delivers the HIGHEST LEVEL of quality - Artie is the one."

FAQs for basement remodeling projects in New-suffolk, 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.
