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

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.

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

In most cases, a contractor will ask you for a deposit that is a percentage of the total cost of your job, but you should never pay in full before work has begun. The up-front cost could be as much as 50%, or you might give a contractor as little as 10% up front. Discuss payment terms with your contractor before they begin the job to avoid surprises.

Walkout basements are not generally included in a home’s square footage, although they may be if they meet certain conditions that depend on local regulations. A finished walkout basement used as a living space may be counted toward square footage in some locations as long as all codes for livable space are met.

It is generally more affordable to finish a basement than an attic, though it ultimately depends on how you plan to use the space. The average cost to finish a basement ranges from $7 to $23 per square foot, while attic renovation costs $30 to $60 per square foot. However, a simple attic conversion to a storage space will cost significantly less.
