"Beyond thrilled with how the entire project went. Universal Roofing & Chimney gave me a good price on a whole new roof plus we did new gutters as well. The cost was well worth it knowing the warranty we have now and to know it was done right. The crew worked well and cleaned everything up when they were done."

"I am extremely happy with the way the deck looks now. Not only was the work completed in a timely manner, but the quality of the workmanship and the attention to detail was amazing. Also, the care taken to remove the pieces of the old deck were really appreciated. In addition, it was a pleasure to work with Chuck from Talex."

"Greg was a lifesaver. I decided to move from New Jersey to Kentucky and it was overwhelming. Greg took charge. I needed some items to be disposed of from a storage unit. He came one evening and took care of that. Then he came back and loaded up that storage unit and my upstairs apartment, all by himself, during the process he communicated everything, was efficient and very professional. He drove my belongings to Kentucky and unloaded them all. My next plan is to build a house here and I’m 100% highing Greg to do the job. He’s highly skilled in all areas of renovations and construction, I’ve seen his work, he truly cares and is an expert in all areas and he goes above to make sure that you feel comfortable in all steps of the way. Thank you so much Greg!"

"Sergio is simply the best! If you're looking for perfection with tile installation, this is your company to hire. Professional, reliable, beautiful craftsmanship, fairly priced and wonderful cheerful personality on top of it all! The entire combination. I had a disaster of a job done previously. Sergio ripped out the existing tile and did an amazing job for me. Every review I've read before hiring him was so positive. This is definitely a 5 STAR company."

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.
