"For the very best value in home improvement construction, I recommend Roberts Remodeling because when you hire Robert Remodeling you get much more than just a contractor; from Planning to Design, to Supplier Negotiations, to Over Seeing Every Detail of the project, Robert delivers VALUE!! His experience, his special ability to recognize great design and complete difficult projects makes him the best choice! I chose Robert for my condo in Long Beach 13 years ago, and then this year 2020 he remodeled my new old home in Island Park with the same high quality, dedication, and skill! No reason to hire anyone else!!! My experience with Robert is not unique, I have referred him to many neighbors, friends, and relatives and they all have the same experience and reaction - they all loved the workmanship and VALUE!!!"

"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."

"I was extremely happy with this company. I liked the fact that he would come to install one door. (Good to his advertisement, he goes to Suffolk county) It turned out to be more than the one door.. He returned my call, the same day. I found Greg, a pleasure to deal with. I chose his company to call, over 3 other names I felt fortunate, it worked out so well, and I made an excellent choice. Now have the name of someone who handles all types of home repairs, that does excellent work. I was extremely impressed, that upon walking up to my door, he removed the snow, off the steps. Top notch company!"

"Domenick is a professional craftsman. He kept to a tight schedule, always showed up on time and did a great job. He gave us creative ideas that would work in our space. Domenick and his team were pleasant to work with. From the moment they entered our home they worked a full day and showed up everyday. Domenick enjoys and takes pride in his work. We are extremely pleased with the final result. Our basement bathroom was transformed into an oasis with a spa feel. The main area in the basement and hallway leading to the basement was also transformed into a warm, welcoming living space. The work he performed in 3 weeks was: Build a new shower/tile with a design/create a shower bench/install shower panel/tile behind the vanity with the design trim/install the vanity/move plumbing, gas and electrical for the shower and vanity with light fixture/tile the floor/install a stackable washer and dryer/build out a wall to divide the storage area and heat unit/install a sliding barn door/paint the bathroom, main room and hallway up to the kitchen door/ installed 3 windows, an air conditioner and installed recessed lighting in the bathroom/installed interlocking vinyl flooring in the storage area, main room and stairs (repaired two broken stairs and lots of extras, e.g. installed a lighting fixture in the hallway by the stair landing, a make up/shaving mirror in the bathroom, installed window treatments and assembled a 70 inch TV storage cabinet). We have booked him for future projects. We highly recommend Domenick and his team."

"Very professional and polite. Came on a Sunday stayed late to try and finish it all in one day. Quality of the work was excellent. They took their time and made sure all ceiling fans and light fixtures were in stalled properly and functioning correctly. Returned a day later and installed 2 new toilets. Highly recommend them."

"We've never had luck with major home modifications—this was smooth sailing the entire way. Our project was a teardown and complete re-side, and Cocos did a fantastic job. We have a tricky home with a lot of angles that make no sense—Cocos did a brilliant job strategizing how everything should be executed, and the 50-year-old home looks brand new. Danielle, Keith and Matt not only executed at the highest level, they stayed in communication literally every day to make sure there were no surprises and that we were happy with the progress. If you're looking for a home siding partner, don't hesitate to hire Cocos. They were top notch and we are very happy/"

FAQs for basement remodeling projects in Oceanside, 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.
