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."

"RUN FAR AWAY FROM ALLIED AND TOM. Tom took my money and did not complete the renovations as per our contract. He lied about having a licensed electrician to do electrical work, it was just one of his workers who's not licensed. I paid for a dumpster and when it was delivered by tom it was already half full from another allied job and I was asked to pay the full amount of $950. Tom didn't listen to anything I said regarding the work I requested and he changed my design and did work that was cheaper for him. I was priced for one of my ceiling's to be ripped out and reinstalled with new sheetrock, Tom waited until I was away on business then he installed sheetrock on top of the bad sheetrock and told me he ripped out the old sheetrock and installed the new sheetrock, I found out when my EC cut holes to install lights and we found 2 layers of sheetrock preventing the lights from being able to be installed. Allied construction is a cheap, sneaky company who will steal your money and breach your contract. Do not hire these people Tom is a lair. Tom wore a gun in my house on his hip and told me "I use this to get paid by customer who don't want to pay". Tom left live 120v wires hanging out of the walls and ceiling, he removed a banister and didn't replace it for 3 weeks making my home very unsafe for me and my 9 year old son."

"Jose and his crew do fantastic work. Did all work as promised and on budget. Only change orders were on our side adding things. Alta was originally hired to replace total roof. Work was completed in 2 days with all trash removed. Our replaced bathroom is now the star of the house! We have hard wood floors and new work matched flooring with no noticeable change. Our last project just completed was a sunroom and shed with partition pavers creating a great sitting area. Everything Alta did was done well and we are so very happy. This is the only company I will use from now on. All of his employees and subs were pleasant, answered any questions we had and very professional."
