DEDICATED GREEN

Mancon is proud to be one of the first dedicated Green contractors in the San Francisco bay area. All the materials we use are selected not only because the components that go into them are Earth friendly, but that the companies that manufacture them are green as well. The techniques that we use in each job are designed to generate as little waste as possible, saving resources as well as reducing costs. All generated is carefully sorted, what can be reclaimed is recycled what has to actually be disposed of is handled in the most appropriate manner. Our job site waste is strictly managed so when we are done the only thing that left behind is the work of the highest quality and the satisfaction of our customers.

To Whom it may concern

I wanted to document the gratitude my family shares towards Mancon, and Steve Mangels, for their superb job in building our newly constructed home in Pleasanton, CA. Mancon’s prompt, professional service from Design to the final Permit signoff was truly appreciated. Your company’s integrity is easily seen in the quality of the finished project. I believe that Mancon went extra miles to ensure the delivery of the very best product and I also believe that’s what will keep our home looking soild for years to come.

I would be happy to recommend Mancon to other developers and homeowners.

With thanks,

Al, Colleen, Gabrielle & Anthony Faccini

A letter from the President

A special thanks to Mancon, and especially Steve Mangels, for the outstanding work you did on the Tenant Improvements for our new building. From the initial meetings with the Architects, Engineers, and City Personnel to the moment you handed me the signed off Permit, your attitude and performance was nothing but professional. I’m happy to say that I’d recommend you for any commercial improvement project and look forward to working with Mancon on our next expansion project.

With my warmest regards,

Al Faccini
