I had a employee driving a company truck by Cenntenial High School give me the finger and yell profanity at me and my 7 year old and 12 year old for no reason. Way to hire someone then give them a company truck way to represent the company. Then he live literally a block from the high school

If you want your project delayed beyond recognition this is your company. If you do business with them make sure you put a deadline in the contract. If they don't want to put it, run!

Report
Called in to get information on a commercial flat roof Here in Pueblo and request help scheduling an inspection. Whomever answers the phone must be a severely overworked employee because she placed me on an immediate hold. (which was totally fine btw. She asked permission and I said I would wait) However, when she picked the line back up and I asked if CTL did any work with commercial flat roofs, she scoffed at the question, put me on an abrupt hold without asking, and then picked back up with an attitude and told me to repeat my question.
I responded that I no longer wanted her help and informed her of how rude she was. (I shouldn't have returned her behavior, but your phone skills are atrocious.) TWO STARs. because I take solace in raising your 1 star review by 50%

I do agree with the other review about cost effectiveness. CTL was costly and it does seem like their services would be best for companies wanting out of the ordinary designs, not necessarily an owner-builder building a simple home. Working with Scott though was a pleasure. He always answered my questions thoroughly and got back to me within a reasonable time frame. For that type of customer service I do recommend them.

There are other engineers in Fort Collins who are more cost-effective. They can be helpful if you're looking for an esoteric building practice like helical piers or pervious concrete, but for common engineering practice or material testing you'll probably want to go elsewhere.
