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."

Basement Remodel questions, answered by experts

In many homes, an unfinished basement is an ideal place for an in-ground pool. The concrete floors, protection against water damage, and access to the ground below your home make this a large contender. Speak with a local basement remodeling contractor to ensure your space is right for the large construction.

Yes, it is possible to turn a regular basement into a walkout basement. Doing so involves excavating the land around at least one side of your basement foundation, installing retaining walls to create a permanent below-grade area outside your home, and then cutting into the foundation to install an exterior door that leads out to the new space. This is an expensive and time-consuming project, but it can add a lot of value and utility to your home.

To determine if your basement walls are suitable for finishing, assess their structural integrity and moisture conditions. Look for any signs of damage, such as cracks, bowing, or excessive moisture. Ensure proper drainage and address any underlying issues before proceeding. 

Consult with a professional if you're uncertain about the structural stability or potential risks associated with finishing your basement walls.

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.

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.
