bobBob’s Custom Windows and Siding, Inc. is located at 1015 North Parker Drive in Janesville, Wisconsin. Our showroom there features examples of our window and siding lines as well as an example of one of our sunrooms. Bob’s Custom Windows and Siding, Inc. was established in 1986 by Robert Scieszinski. Bob’s father, Jim, had been in the siding business since 1947. When Bob bought the business in 1986, he expanded it to include replacement windows. In 1995, Bob joined the franchise of United States Seamless and began doing seamless steel siding. In 2002, he added seamless steel log siding to his service offerings. The business also performs work on doors, gutters, gutter guards, fascia, soffit, roofs and sunrooms.

Client Testimonials

  • “Tell all of the guys on each of the crews GREAT JOB! It looks wonderful!! Thanks for the hard work and always addressing all of our questions and concerns.”

    June & Jim
  • “The men did an excellent job. The garage looks beautiful! My husband Jim worried for about 4 years about getting the garage done but he was too sick to do it. I wish he could see it now. He would be as happy with it as I am! It looks like a new garage. Thank you so much!”

    Arlene
  • “Once again I have the pleasure of thanking you and your crew for a beautiful installation of windows and doors on our home. I thought no one could beat the considerations shown by your siding installers, but we were proven wrong. We are pleased with the professionalism shown by Josh, Ed & Randy. They work well together to make the transition from old to new as painless as possible for the homeowner as well as taking care to clean up before they leave. Truly, it is appreciated.

    We will keep you in mind when the time comes for more changes to our home, and will be more than happy to recommend you. Again, my thanks to you and the “guys” for making me a very happy homeowner.”
