W.W. Grainger Corporate Offices

“This project is a perfect example of achieving desired results and smooth and timely completion as result of teamwork. Pepper Construction Company could not have achieved such a success without the help of each and every subcontractor including your firm.”

Pepper Construction Co

Chicago Patrolmen’s Federal Credit Union

“I received your submittal for the Chicago Patrolmen’s project and have to say that it is the single most thorough and complete submittal package I have ever seen from any subcontractor. Too much of my day is spent calling subs and arguing about incomplete submittals or unauthorized product substitutions. Therefore, I wanted to take a moment and thank you for the effort on your part. It certainly reflects well on Spray Insulations as a company and yourself as a Project Manager. I look forward to working with you on this job!”

GETCO Relocation Project

“I would like to take this opportunity to thank you and your firm for all of your hard work and dedication to the GETCO Office Relocation project at 350 Central.

The GETCO Relocation project was one of the largest tenant build-out projects in Chicago for 2011 and was one of the most technically challenging projects in the city as well.

Through all of the project challenges, the performance of your firm helped to make this a highly successful project and we want to thank you for a job well done by all of those involved.  We truly appreciate your teamwork and commitment to success.

My project team and I look forward to working with you and your firm again in the future.”

O'Hare International Airport, Restroom Modernization Project

“Tough schedule, tight airport security, confined work area, detail patterns … Phenomenal finished project. Thank you!”

Frank Granat, Project Superintendent, Castle Construction

St. Linus Church

“Due to the generosity of a donor to the parish Millennium Campaign, the parish purchased new solid oak pews to replace the forty-seven year old veneer pews original to the church. The removal of the pews enabled us to restore and refinish our terrazzo flooring. After seeking multiple bids, we chose to go with John Caretti & Co., who came to us strongly recommended, they too did a superb job on our floors. Mr. Tom McHugh, the project manager, was very helpful and always available. As in any complex project, at the end of their work there was a slight problem with the final sealer coat on the floor. When our concerns were brought to Mr. McHugh’s attention they were immediately and satisfactorily dealt with. I would highly recommend John Caretti & Co. for future projects.”

Rev. William T. Corcoran, Ph.D., Pastor, St. Linus Church
