 Trustindex verifies that the original source of the review is Google. It was time to replace our roof; our tiles were rotting away, the previous owners had stacked tiles three deep, and we would frequently encounter leaks & scattered roof tiles in the yard after storms. We did our research, and decided to go with Anderson Ballard Construction.  Travis was a pleasure to work with, the install was timely and efficient, with the entire job done cheaper than alternative quotes.  We’ve now been through a 100-year windstorm and two rains this winter season, but the roof tiles haven’t moved an inch.  It’s nice having a new roof over our heads, and I wouldn’t hesitate to recommend ABC.

 Trustindex verifies that the original source of the review is Google. We are very pleased with the remodeling work they did on two of our bathrooms. They started when they promised and finished the work on schedule. They were very competent and worked hard to do what we asked them to do. They also gave some good advice on what would work best and how to save money. They were also very nice people.
