Testimonials – Detroit – Youngstown – Pittsburgh


This letter is being written to express congratulations of a job well done at the Chrysler Data Center. As you are aware the 5000 gallon buried fuel oil tank was changed to a double fiberglass body and was late in arriving to site for installation. A herculan effort was made to install the piping of the day tank and the containment piping to the buried tank. Again, thank you for a job well done and for the honest effort and neat workman like manner of installation.

Superintendent, Barton Malow

Dear Randy,

I would like to commend De-Cal on their recently completed work on the Chrysler Technology Center's expansion to the Health Activity Center. The project truly benefited from your staff's input and efforts during the construction phase of the project. I feel that De-Cal went the extra mile to insure the best of installations. I look forward to working with De-Cal on future projects.

In February 1996 Ford Motor Company had De-Cal Mechanical install systems (Glycol; Water and Compress Air) for several temperature chambers and chillers at the Electronics Technical Center. De-Cal's work was well performed and met all Ford Motor Company's specifications. This work was completed well within our timing requirements. We recommend De-Cal's services and are looking forward to working with De-Cal on our future projects.

Dear Mr. DeBeul,

The installation of the new boiler for the finned tube radiation system was timely and created minimal disruption to our faculty during the heating season. I was pleased with your company's ability to start the project on time and follow through with a clean work area and a balanced system. I appreciate the service your company has given our Romulus site. I will recommend your company to other GMPTG locations.
