"Because I just had these rods installed a few days ago (and now it's Nov 26, 2021) I haven't had enough time to evaluate the work quality and value - but I have no reason to doubt that both are good. I priced materials for this job, as I originally planned to install themselves, but when I realized that I truly didn't want to get up on the roof of my house (which is quite high) or to get on the roof of my barn (metal, thus slippery) I decided to hire the pros. So that I am very happy with and of course it therefore cost more than it would have if I had done the job myself - but it was safer for me, and also much quicker than I would have been. So, I am glad I called W B."

"Jeff did an excellent job handling many different aspects of a complete home renovation. He built and tiled a custom shower with bench, drywalled and finished the ceiling and walls in the basement, and painted the interior of the home. There is not one aspect of a home that I wouldn't trust Jeff to be able to address."

"Ben was a great sales person and very helpful. Installation was a one day experience and the installers were respectful and friendly. They both wanted to take my dog home with them! One suggestion for consumers—think about where you stand in your current shower to determine where to place your”condiment” rail and whether you prop your foot on the tub edge to wash and dry your feet. You may need to put in a shower chair just to feel safe to finish. The shower is clean and easy to clean. I love it. Even though it’s expensive, it’s worth the quality."
