"Rahat Construction did an amazing job repairing my basement and waterproofing the exterior of my house after Hurricane Ida. They regraded the cement, replaced the basement doors, re-fortified and repainted the damaged basement walls and replaced the badly cracked cement on my sidewalk. They are highly responsive, they work very quickly and carefully, and above all, they care about their customers—always taking time to explain decisions and new issues as they arise. This is the second time I’ve worked with them, and I would hire them again in a heartbeat."

"I hired Done-Rite on the recommendation of my neighbor. I viewed the quality of work they had done for her. I first had them refresh my guest bathroom. I needed a shower pan & shower doors replaced as well as a new toilet, vanity and light. I could not have been happier with the result; so much so that I hired them to do a complete on suite bathroom remodel a few months later. I had a jetted tub to shower conversion. I am completely satisfied with my beautiful new bathroom. Dan & Dan were wonderful to work with. They pay so much attention to every detail and are very professional. I was sorry to see them leave but will happily hire them again for my next project. I highly recommend them to anyone looking for quality work at a fair price by someone you can trust in your home."

"I used TKT Remodeling Group LLC for a complete basement remodeling. Treon had wonderful ideas about ways to make my basement function more efficiently. He was the only contractor who took the time to discuss ways to remodel the basement that made sense (e.g., moving the bathroom and closet) into spaces that increased our living space. Treon and his crew are friendly, respectful, punctual, professional, and responsive. He even surprised me with a new, functioning fireplace. I wish I had taken before and after pictures. I was able to go to work and leave the workers alone in my home with no problems. Even after my basement project was completed, I called Treon with questions, and he responded quickly. I highly recommend him and will use him again."

"I’m so pleased with the remodel of my powder room! Proper Contracting did an outstanding job from start to finish. They were timely, kept the workspace spotless, and kept me informed every step of the way so I could make important decisions about fixtures and placement. They were courteous, professional, and a pleasure to work with. Their pricing was fair, and they seamlessly incorporated the materials and fixtures I had purchased separately. I couldn’t be happier with the results and highly recommend Proper Contracting!"

FAQs for basement remodeling projects in Brooklyn, 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.
