Castro Construction did an excellent job painting and sanding my deck and painting my ceiling. They were very detailed and professional. They cleaned up so well! They even mopped the floor after! Highly recommend!

I had a great experience with Castor Star. I wanted to paint the exterior of my house and talked to quite a few contractors. Hans gave me a very reasonable quote with a great warranty. They worked every day, used high-quality paints and did not make a mess. I am very happy with the outcome. I have no reservation recommending Castor Star.
