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."

Architectural student -turned engineer -turned entrepreneur. As a builder contractor in the field for over 30 years, I understand that honesty and integrity come first. I run a crew of four men, who I conduct on the job everyday and I am always on the job site. I'm now 30 years in business successful and still dedicated to my client's total satisfaction. Trying and succeeding to do a professional job for one important person at a time - you.

"Tanem has a long history of good work. Gene did several projects for me years ago and I was glad to find Paul picked up the same qualities Gene had established. Both are easy to work with, knowledgeable, make lots of helpful suggestions so the project comes out even better than I had thought it would. You tell Paul what you want done, and he, and Gene in an advisory role, find a way to make it even better. They are flexible and just know how to find solutions. Their crews know what they’re doing. Paul keeps checking and keeps you informed as work progresses. I couldn’t be happier to see Paul continuing the Tanem tradition."

FAQs for second story addition building service projects in Uniondale, NY

For many homeowners, building up is worth the expense because it provides the extra bedrooms or living areas that can’t be accommodated within the existing footprint. A larger, updated home often commands a higher resale price, recouping a sizable share of the project cost while allowing you to stay in the neighborhood you love. Run the numbers with a real estate agent and contractor to ensure the expected return and day-to-day benefits align with your goals.

Whether it makes more sense to build up or out depends on your lot, budget, and local code. Building up preserves yard space and involves less foundation work, but you may need to vacate the home during construction. Building out avoids staircases and can proceed while you stay put; however, it encroaches on the yard and may face setback limits. Compare both options with your contractor before making a decision.

A structural engineer will first inspect the existing foundation for cracks, footings, and load capacity. Depending on the findings, the crew may pour new concrete footings, install steel or concrete piers, add reinforced beams, or tie additional rebar into the slab. These upgrades redistribute the weight of the new floor and bring the structure up to code. Your contractor will outline the specific reinforcement plan and timeline once the engineering report is complete.
