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."

"I am not a review writer at all, however, I felt it only fair to write a review for Eric and Just Rite HVAC after a wonderful experience. This company and Eric the owner are, in a word, the BEST! I needed main floorâ s central AC replaced. A friend recommended me to Eric. I texted him and he responded with a few hours. setting up an appointment was fast and easy. Eric was knowledgeable and timely. My job was extremely difficult based on the location of my air handler and there was a high chance the ceiling would need to be opened for access. When Eric arrived for the job he inspected further and said he was going to try not to have to open the ceiling for access. He and his crew went well beyond what anybody else would have done and meticulously dismantled the old air handler piece by piece. It was time consuming, difficult and energy consuming. But they were able to do and saved me from having a gaping hole in my ceiling. They did an excellent job setting up the new air handler in the same location and even fixed errors the previous installer had made! The entire crew were highly professional, courteous and clean. They put down drop cloths everywhere and cleaned up everything when they were done. I highly, highly, and without reservation, recommend Eric and Just Rite HVAC and will tell anybody I know about them."

Plumbing questions, answered by experts

There are warning signs that your copper pipes may be failing. These include discolored water, decreased water pressure, visible cracks and leaks, built-up green rust, and corrosion. If you know the copper pipes are reaching the end of their life span, consider having them replaced or at least having a professional assess your plumbing system.

It is okay to use a drain auger on a toilet, just make sure you are using the correct tip size. The auger is a plumbing snake with a protective sleeve to protect the porcelain toilet bowl from getting scratched. Using too large of an auger can cause the snake to loop back and damage the inside of the drain and plumbing.

While the law varies from county to county, most do require that a gas shut-off valve be installed in any newly constructed homes or be present whenever a home is sold, or there is a transfer of title. The valve you install must be on an approved city list—these models satisfy the regulations and requirements set by your local jurisdiction.

National emergency plumbers usually have greater availability to address emergencies because they have more professionals at their disposal, but local plumbers may be located closer to your home and can arrive faster. We recommend contacting one or two local plumbers first to see how quickly they can arrive. Move ahead with the service if it’s within a reasonable time frame. If not, contact a national company to see if they can get out more quickly. National companies sometimes outsource work to third parties, which can often mean faster response times.

As the temperature outside warms up toward the end of winter, your pipes will thaw on their own over time. However, the process is not quick, and it depends on how extensive the blockage has become. In addition, a frozen clog can cause severe damage to your plumbing if left unattended.
