Keith Gerstenmaier -- Owner

Keith Gerstenmaier has been working and living in Fairfield County for more than 40 years. His professional background is as diverse as his visual aesthetic, which is thoughtfully eclectic.
 A skilled artist, designer, carpenter, and builder (with a business degree), Keith’s formidable talent and experience continue to be valuable assets to his work and to his clients.                                                                                                           

James Cocks -- Owner

Jim Cocks, a longtime Fairfield County resident, brings exceptional skills and broad-ranging experience to the business of building. Jim’s get-it-done right (and right now) approach to the business ensures every job he oversees  runs efficiently and on time.  His attention to clients’ needs is uncompromising and  virtually unheard of in the home renovation business

What Our Clients Are Saying

Our expectations have regularly been met, and often surpassed.  Coger’s attention to detail, and willingness to work with me to do things the way I want them done,  is outstanding.  And always with good humor and a smile.  Incredibly patient, and I’ve never yet given them a problem they can’t solve.  And I’ve tried!"
​
We love our Rowayton home.  Thank you so much for all you've done to make our little old house look so beautiful and feel so welcoming."
Home renovation is extremely taxing for the owner even when the project is going to plan and to budget.  The fact that we continue to depend on Coger is a testament to their professionalism, care and sense of shared responsibility."
