What Our Customers Are Saying

Paul T

I just want to message the business owner how pleased I am with the work performed by Brad and Clay on August 1. The guys were professional, friendly, and clearly knew how to efficiently solve my gutter drainage problem. The patio looks great after cleaning and they made sure to "tidy up" the back of my property. I've already recommended DeMark's to a friend with a similar gutter issue. I will be calling you folks again if I need work in the future.
