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."

With US HOME / STARS AND STRIPES has been servicing homeowners for more than 25 years. Customer preference and priorities are always first. We're very timely with our work and never lose attention to detail. Give us a call for your free estimate.Deal direct with owner. FULLY LICENSED: Suffolk County Nassau County

"I can’t recommend Stars and Stripes highly enough for anyone considering a home renovation. From big projects like installing new countertops and a backsplash to smaller details like fixing the track on my sliding closet doors, everything was completed with exceptional care and attention to detail. What really sets them apart, though, is the trust factor. I’m not someone who’s usually comfortable leaving people alone in my home—but with Stars and Stripes, I never once had to worry. They were respectful, reliable, and I always felt my home was in good hands. It's rare to find that kind of peace of mind with contractors, and it's what will keep me coming back for future projects."

Basement Remodel questions, answered by experts

Yes, you’ll use a macerator pump to install a basement bathroom without breaking concrete. The purpose of breaking into concrete is to connect the drain pipes to the main sewer line. But a macerator pump will bypass this step and break up solids until they are soft enough to pass through a discharge pipe. That pipe will carry the waste to the sewage line.

Home improvements that increase value not only enhance quality of life but also offer a high return on investment (ROI). Replacing a garage door has one of the best ROIs at 93%. Other high-ROI projects include remodeling your kitchen, installing a stone veneer, and replacing windows. These updates make homes more appealing to buyers and improve functionality, which helps if you plan to sell your home in the future.

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Lifting a house and adding a basement is one way to add usable square footage. Lifting or jacking a house is a complex process, and it can be expensive, not to mention that you won’t be able to live in your house while it’s lifted, due to safety concerns. Lifting a house should only be done by experienced professionals.
