"If you are in need of a professional with vision and integrity, Robert is the only one to hire. After a basement flood, we interviewed 3 other companies, all of whom wanted an exorbitant amount for the project and also wanted to charge for a written estimate. Reliable, knowledgeable on all matters of construction, mindful my budget and a true professional. His work is meticulous and he leaves your home spotless every day. I got lucky and so will you!"

"After my family and I decided to move back to the old Queens house I grew up in to live above my mom, we quickly realized there were many things that needed to be repaired. I've counted on Nunez Construction and Painting for all of it. The first job they did was to repair some siding on the house. Prior to our move, we then wanted to gut and remodel the second floor apartment where we live. Mr. Nunez and his crew did a great job. More recently, our basement became flooded with sewage. We called him again to help with this project and install a new floor. We are always very satisfied customers. The work is great and reasonably priced. We can't thank him enough for being a wonderful person and company to work with."

"I hired Long Island handyman construction group to remodel a 400sf basement and bathroom in Melville. They were priced in the middle compared to other bids. I picked them thanks to their out of the box advice which saved me thousands of dollars. There was one problem with the plumbing which cost an extra 1800 dollars. The owner settled with me 50/50 even though it was a pre-existing issue. The project was started early and completed early. All mess was cleaned up and the crew was very friendly and fully aware. Very reputable guys and very easy to deal with. Thanks Moises and Eddy."

"We have worked with Anthony from TAS Construction since 2006. He built a 2nd story addition on our home and completely remodeled the first floor. His work and crew are professional and courteous and you see right away that Anthony cares about his clients. After Hurricane Sandy destroyed the 1st floor of our home, Anthony was there to help us repair the water damage almost immediately. Fast forward to August 2020, and Anthony made time to give us an estimate for some recent storm damage in a few hours. He knows his stuff and has a great eye and ideas that look amazing when implemented. We constantly get compliments on our home and never hesitate to recommend him ."

"Interior Source transformed my bathroom into a dream space. I initially hired them to renovate the bathroom, and I was so impressed with their professionalism and the quality of their work that I decided to have them renovate the entire basement as well. The results were exactly what I had envisioned—if not better. They exceeded my expectations, even addressing a pipe that was incorrectly pitched—a problem I hadn’t noticed. The team completed the project on time, and despite my busy work schedule, I felt completely comfortable trusting Interior Source with my home. What stood out most was their willingness to address all my concerns and go beyond the contract by fixing various issues that weren’t included in the original scope of work. Throughout the project, they offered valuable assistance and provided alternative solutions that enhanced my vision. Although I am satisfied with the outcome, they assured me they would return to address any repair issues or concerns if needed, which gives me great peace of mind. Their commitment to customer satisfaction is truly unmatched, and I can’t wait to have them remodel the main level of my home next."

"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."

"We found Paul and Gene at Tanem construction through Homeadvisor 4 years ago and have had a project with them every year since. From finishing our basement during Covid, adding a full bathroom wet bar and laundry room, to restoring and building our front stoop to adding heated floor and a 2nd floor full bathroom restoration, to even the smallest of jobs in roof repairs and ceiling leaks. Tanem construction does it ALL. A pleasure to work with. A local family run business that will sure to fulfill all your construction needs."

Basement Remodel FAQs, answered by experts

Making a window in a basement larger costs an average of $4,200. You’ll need to pay an average of $550 to have a structural engineer plan the project, $500 to $1,500 for the installation labor, and an average of $2,200 for the excavation and window well installation. The remainder will go toward pulling permits, installing trim, and repairing drywall on the interior.

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes. 

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.

Building a bar in the basement will likely add value to your home, although it’s unlikely that you’ll see a significant return on investment (ROI) unless you plan on using the space for you and your guests. If you think you’ll use the area frequently, though, it’s probably worth the investment, and you should see a bump in value if or when you sell your property.

Yes, most general contractors require an initial down payment, typically between 10% and 25% of the total project cost. This upfront payment helps cover the costs of materials, permits, and subcontractors. The remaining project costs are usually billed after specific project milestones are reached or on set completion dates, as outlined in your contract. Be wary of contractors who require a significant deposit of 50% or more upfront, as this could be a red flag for a scam.

It is common for a contractor to ask for a down payment before starting a project, especially for jobs that require purchasing materials and equipment or hiring a crew. The deposit amount can range from 10% to 50% of the total job cost. While a request for up to 50% is not unusual, a contractor should not ask for more than that, and you should never pay for a project in full before the work has begun. To protect yourself, always discuss payment terms before starting and have a written contract that outlines the project timeline and expectations. Additionally, be sure to hire reputable contractors and check their licensing and insurance before the project begins.
