Cowen installed new tile floors for us. The crew kept the house clean while they worked, were very professional, and talented. We love this the floors turned out.

Garrett Cowen and his team do great work! Garrett saved me not once but three different times in the last 6 months. When I reached out for contractor support he arrived that day to evaluate and the problems were completely fixed within a week, each time.
Definitely fast and professional, and for a fair price! -John Morris

I cannot say enough about Garrett Cowen. A man of faith, integrity, and genuine care for his fellow man as well as excellent craftsmanship. When we were blessed to find Garrett, we never expected how much he would go above and beyond our expectations. Please, consider Cowen Construction and Roofing for your next project. You will not be disappointed! Thank you Garrett, we will remain eternally grateful!
