"We live in Bronxville, where the expectation are high for quality of work done on houses. Bud, and team, did an amazing job with a pretty large job. It was a full basement remodel, down to the studs, and he was great to work with. Really appreciate his professionalism and quality. I would recommend him fully, even for jobs that are larger and require a high level of finish quality."

"CT basement did a phenomenal job finishing our basement and we could not be happier with the results. They made every step of the process from design to the finished project simple and straightforward, everybody was easy to work with and made our opinions and needs the top priority and they were able to perfectly translate our vision into the final product. This was a fairly large project involving finishing 1200sq ft with an office, gym and full bathroom and their experience and expertise was obvious. They definitely understand the specific needs of a basement while making it look like any other room in the house. We would use them again in a second, we’ve even been joking about tearing down the rest of the house and just living in the basement!"

"We had our kitchen completely remodeled by Hire Her Home Improvement. Angela and her crew were very professional and responsive throughout the whole process. They were punctual, efficient, and always left the house clean when they left for the day. They were very respectful of our home. The job was completed on time and the kitchen came out beautiful! Angela was always available to answer any questions and always kept us updated. She is very knowledgeable, patient, and a pleasure to talk to. All the costs were clearly communicated and there were no surprises. I would highly recommend Hire Her for any home remodel or repair!"

"We hired Gustavo to remodel a 1960s house we purchased and we are pleased with the outcome he and his team delivered. Remodeling included vaulting our living room and kitchen ceilings, adding steel beams and refinishing kitchen and bathrooms with new plumbing, cabinets and tiles. Gustavo is very knowledgeable in all aspects of construction and the codes. His team and the subcontractors listen to him and they work together very well. Overall, we were very pleased with his work and we would hire him for future projects again."

"Our kitchen remodel went extremely well! We have done several remodeling projects and Custom Home Pro stood out way and above anyone else we had used. Marcio, who is calm and easy going, was extremely easy to work with. In addition to managing our kitchen project, Marcio also helped us design the kitchen on our own, saving money on a designer, & hired an expert cabinet maker. There were also no cost overruns on our project, even when extra work was sometimes unexpectedly required. Our kitchen is beautiful and we are always getting tons of compliments. Thanks to Marcio and his professional team!"

"Anderson is a miracle worker, installing a shower in our basement bathroom when other contractors said it couldn’t be done or would be outrageously expensive. Anderson did the work in a short time, cleaned up all the debris and left it spotless. His cost was very reasonable and he used his contractor’s discounts for the materials. He communicates very well so I knew when he was coming and going. I was consulted at every step. I highly recommend Home Innovation!!!"

"My wife and I were looking for a contractor to remodel our master bathroom. We were looking for someone that was knowledgeable, honest, fair in pricing, and great with communication. Victor from VAP Contracting was exactly that. Victor told us exactly when he would start, what he would need, and always answered any questions that we had. His team arrived every morning on time and was very polite. They were very neat and cleaned up each day and truly did an amazing job! Our new bathroom looks great. Victor stands behind his work and we look forward to working with them again on other projects that we have."

FAQs for basement remodeling projects in Thornwood, 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.
