"Hired Greg for a full gut and remodel of a bathroom. Greg was very competent, personable, and took the time to understand exactly what we wanted. He made us feel like we were in good hands. He took the time to make sure things were done the right way. The result was top notch, couldn't have asked for more. I would definitely use this company again!"

"Jose and his team were the best team I have ever had work on a job in my house. Jose went WAY above and beyond to make sure we had our basement back in order in a timely fashion. He was willing to work after hours if needed to help get our finished basement back after we had suffered a sewage leak and had to wait until mitigation was complete. A 3-4 day job was complete in 2 days! And one of his workers, Carlos, from the second day stuck around to help me get the heavy and large items back into the basement. There was a previous review that said Jose was very emphatic to their needs and that is so true. That review actual was what made me give Jose a call. I wish there was a word better than highly recommend. Thank you Jose and your entire team!"

"Quite a few years ago, Artie renovated our bathroom.  Not only did he do a super job, but he made so many helpful suggestions along the way making decision making much easier.  For example, he suggested the type of tub to install and ones to avoid.  He helped us order merchandise and we were able to get a contractor's discount!  <br />      Recently we wanted to add a stone grilling station and a gazebo to our yard.  Everything I shopped for, I did not like or it was way over priced.....Artie sat with me and helped design a BEAUTIFUL, river rock-blue slate grilling station.  Once again, he directed me where to get the grill, type of grill, what to avoid and what would look best.  He takes the time to listen and know exactly what the customer is looking for.  He made everything by hand and the result shows....We get so many compliments from it!  He is currently completing a Tiki Hut Bar/Gazebo........when it came to ordering the tiki hut straw for the roof, Artie took it upon himself to google information online and forward me what he had found.....this made it so much easier on my part!  The bar came out great!!! <br />      Not only is Artie extremely talented, but he is so easy to work with, is very professional,responsible and shows up for a job when he says he will.....when do you ever get that?????  I HIGHLY recommend Artie Derosa!!"

FAQs for basement remodeling projects in Mastic Beach, 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.
