"Arthur gave us a fair and competitive estimate and was able to start work quickly thereafter. He and his team did an excellent job gutting and totally remodeling two bathrooms and a closet as well as redoing some of the wood flooring, moving vents, and moving hallways. Arthur himself was at the home everyday and did the important work himself. He also went the extra mile in helping us with small projects around the major project as they came up. He was extremely responsive in provided us with timely updates. When complications occurred (due to the house having not been renovated in 40 years) he was clear and helpful in keeping the project on schedule. He was extremely honest and I trusted him to be alone in my house for weeks on end with his team. I would/plan to work with Arthur again in the future for my home renovation projects."

"I highly recommend Loja Renovations & Fine Carpentry LLC! Manuel and Fabian were professional, courteous, and did an outstanding job. They helped me with several projects in my home, including mounting two TVs, installing a shoe rack, hanging a very heavy mirror, putting up window shades, and installing several shelves. Everything was done carefully and professionally, and they were extremely helpful throughout the entire process. What I especially appreciated was how prompt and reliable they were. They came all the way from Corona, Queens, and arrived ready to get everything done. Their attention to detail and quality of work really stood out. They offer a wide range of renovation and carpentry services, and based on my experience, I would absolutely hire them again for future projects. It’s not always easy to find people who are dependable, skilled, courteous, and take pride in their work, so I’m very glad I found Manuel and Fabian."

"I have now had 4 pickups from this company. Each time it has been with different items: I have had my kitchen remodeled,  a deck torn down and rebuilt, a new roof put on, old fencing disc arded, and a yard cleanup. The only difference in pricing was for the roofing and even though ti was more money it was STILL CHEAPER than a dumpster!!! I don't know how these guys do it, but they pickup on time, without issue andfor the cost quoted. I have turned each of my contractors onto them - now they are using them. SO MUCH cheaper and better service than any dumpster company I have used!"

"I am very pleased with the result. There were some odd-ball aspects to the work requested, and Justin accomplished all of these well while having to do a bit of creative thinking to make everything work as expected. The work is neat, and was completed in most of one day. Arrival was prompt, and clean-up was good. Now a dark corner of my basement is illuminated, and I have a working utility sink there. I can continue the task of setting up storge shelves and a workbench myself.

"Anthony Gandolfo gave a very reasonable quote for our bathroom remodel.  He laid out plans clearly and gave us day-to-day updates throughout the process.  The job took a little longer than expected--3.5 weeks as opposed to 2.5 weeks, however there were unexpected delays.  
Anthony does beautiful tile work!!  Please be sure that he is the one on the team that does this part of the job, as he is meticulous. He doesn't mind you pointing out any little detail that might need more attention.  The only major problem during the job was a leak that was discovered in a heating line after the ceiling had already been sheet rocked.  Anthony addressed the issue quickly and his plumber was came to the house later that day to eventually fix the issue.
Both bathrooms turned out great!  There was an unresolved plumbing issue in the main bathroom (the shower runs ever so slightly while running a bath), however overall we are very satisfied with how it turned out.  My family would definitely consider hiring Gandolfo Contracting again in the future.

FAQs for basement remodeling projects in Fishers Island, 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.
