"Daniel and his team (Ricardo and Miguel) are awesome. The knowledge and thoughtfulness of each feature, the combination of design elements and finishing touches is exceptional. And patience. We ask lots of questions and ask for an adjustment here or there and every time it was done with a smile and not a problem. Talking through the practicality, functionality and aesthetics of each feature how they work together and listening to recommendations from Daniel made a big difference in the final outcome. From cabinet size, to vanity, to mirror placement, shower niche size and location, to custom board and baton height and finish. His knowledge and his teams execution are a great combination. We look forward to working with Monterroso again and have recommended them to others."

"We had Robert perform yet another project at our house. This was a challenging one as it was extending our kitchen and matching the previous build as closely as possible (without knowing who did the original build). As always, his work was flawless with a tremendous attention to detail, and patience in finding the proper pieces to make it work. He also added cabinets and a sink to our laundry room. Could not recommend him more greatly for any project."

"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."

"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! "

FAQs for basement remodeling projects in Syosset, 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.
