rushforthlogo.aspxIt’s not very often that I have the time or the desire to write a letter of thanks and appreciation. As a Superintendent of construction we meet all walks of life, mostly good people that work hard and are proud of what they do. Then there are the ones that take it to the next level, by this I mean team involvement. Castle walls just finish a wall system for my project in record time saving the project from erosion & safety concerns.

Not only was the wall built quickly, Roger Coates, President, and his office staff engineered & submitted the drawings as part of their service. One stop shopping greatly expedited the process with winter on its way; this was a much appreciated effort. In closing I need to mention the dedicated field team: Jerry, the superintendent, who very much enjoys his job and the crew he leads. This has been a truly great experience and look forward to projects together in the future.  Thank you all at Castle Walls for all that you do.

sellenHi Mike-
It’s not often that I get to work with someone like your company President Roger Coates.
When I first encountered him at our King Street Station project, Roger was on his hands and knees explaining the grade changes to our knowledgeable crew.  When I realized who he was I found him to be quite engaging and appreciative of Sellen Constriction Co. for being ready when we said we were.  Your Castle Walls crews were respectful, compliant, & embraced our Pursuit in Safety Excellence policies.

Mike, I was skeptical at first, but you did meet both my schedule completion dates and delivered a quality installation.  We will have you back again once the temporary restrooms and covered waiting areas are cleared out, to replace appox. 30 brick and for the minor patch repairs.

Feel free to use myself as a reference, as Castle Walls came prepare, installed correctly, and left a cleaner work site that you received.

Thanks again, Happy New Year to you and Mr. Coates’
