"We could not be happier with the work done by OZ. We’ve done countless home renovations over the years and the level of professionalism, attention to detail and attentiveness we got from OZ were unmatched. The design that was done by Uzi (owner) and Lori (designer) was an easy, flexible, and enjoyable process. The level of customer service we received from Mike (the PM) was something we never before experienced. To call him just a project manager is a vast understatement. He checked in nearly every day to keep us abreast of the project status and showed us in detail what work was happening and why. When we had design decisions his considerable experience was invaluable. When the team was shorthanded due to Covid, he put on kneepads and did the work to keep them on track. He never forgot a single item that we discussed and made it unnecessary for us to keep our own punch list. All of this is great but what matters most is the final product and this is where OZ shined. Caesar (crew leader) and his team had impeccable attention to detail and never took a single shortcut. They completely redesigned our kitchen, updated our den, built us a new custom fireplace, installed several new windows and replaced nearly half of the floors in our house. Several months later it is still impossible to find any issues. Everyone who came to our house was polite, professional, and patient with our questions. As far as we could tell they all worked for OZ and none were subcontractors. The cabinets are built here on Long Island by folks who support families on the Island. When they did hit installation issues, the cabinet builders themselves came to the house to resolve them! When friends come over to check out the work, they are consistently amazed and can’t stop complimenting the project. Anyone who has done even a few home projects will realize how rare this all is. We’ll never do another remodel with anyone but OZ. Great work guys!!"

Kitchen and Bath Works Inc has been owner operated and successfully in business since 1994. Offering a consultative approach and delivering on quality, custom work, our business has been overwhelmingly driven by word of mouth referrals. From start to finish, we stand by our work and our owner is committed to being present on all jobs.

"Lou renovated my kitchen last year and I was completely satisfied. I called him back this summer to gut and remodel my bathroom. He was extremely considerate, and he treated my house as if it were his own. My house is small, and I only have one bathroom. The project took nine days. I was anticipating that there would be a big mess and a huge inconvenience. But even the demo was done very neatly and efficiently. Lou even took the time to re-connect the toilet each night so that I wouldn't be left without. Lou did an amazing job, and it was a pleasure working with him. Once again, I am pleased to recommend Lou for your kitchen or bath project."

Our mission is to service our customers in a prompt and professional manner. We do not consider a home improvement or remodeling project complete until the work is finished, the job site is clean, and the customer is completely satisfied. Licensed & Insured since 1997

"This is an overdue review. I hired Bernie and his team for a kitchen remodel in June 2021, after he did an excellent job with my three bathrooms in 2020. The kitchen remodel was also excellent. His works are efficient, hardworking and clean. My remodel took two weeks, as he had quoted and for the exact price he had quoted. I would hire him and his team again and I referred them to a coworker for her bathroom project. She was also very pleased with their work."

Basement Remodel questions, answered by experts

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.

Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms. 

Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.

Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.

Finishing a basement normally takes four to eight weeks, but the timeline depends on the size of your basement, your contractor's availability, and the extent of finishing work. Framing the basement will take three to five days, while adding electrical and rough-in plumbing can be another three to five days. Adding drywall can take five days, and floor installation can take two to three days. Final touches, like painting and adding trim, will take another week.

Building up by adding square footage to the top of your home is often less expensive than adding a basement, but it depends on the specifics of your house, your property, and supply costs. Because building a basement requires excavation, it can be a more expensive option than building up.

Renovation enhances functionality, increases home value, and can add new space for personal or family needs. It typically modernizes older unfinished basements for new uses.
