Testimonials  (
  • "Ken the project went beautifully. The crew showed up on time, and with a crew of 5 guys, did the whole job in one day.
  • They custom built the portico on site. There were a few little things I asked them to change, (such as color of flashing) etc. and they were very accommodating.
  • Although the company drew a diagram of my home with the portico beforehand so I could see what it would look like, the project turned out more beautiful than I expected.
  • The workmanship, attention to detail and the quality is evident from the street.
  • Another bonus I was not expecting....they covered all the wood parts with aluminum siding material, making it virtually maintenance free.
  • The whole process was a pleasure and hassle-free!"
