"I was very pleased with my finished products I had waited a very long time to have a bathroom installed on the first floor. The problem was that I had very little space where it could be placed. I worked with Jake from West Penn who designed a perfect small bathroom for me when others said it couldn't be done......and it turned out to be not only modern and functional but BEAUTIFUL too! They also remodeled the adjacent laundry room and entrance and added a closet that, when completed, blended in perfectly with the room decor. I was very pleased with all that was done. Jake was easy to work with and provided helpful suggestions that I appreciated and used. The workers were super -- personable, skilled and professional, and punctual as well. As is often the case when working on an old house, there were a few unexpected problems that needed addressed before work on the bathroom could continue. I was both grateful and impressed that when the job was finished I was not charged a single penney above the price that I was quoted at the beginning. I would definitely recommend this company to anyone. In fact I have done just that and they are now contracted to do several projects for my daughter. Thank you so much Jake and staff!"
