"I highly recommend PDX Top Finishes! Their work is very solid and done thoroughly and well. The owner, Rafael, is very professional, honest, and trustworthy. Rafael worked very hard to fit us into their busy schedule and even finished the project ahead of time. We were very happy to find PDX Top Finishes on the Angi website. They were the first to quickly respond to my request and we were very happy to find this very capable company with amazing workers. They were able to tackle our project (that a few other companies said it was too major of a project to handle). PDX Top Finishes handled our project easily and went above and beyond."
