Construction Services Since 1986

Baltimore Based, Family Owned

Who we are:

Started in 1986 as a family owned company, KAT Construction has  always strived to be a premier, commercial construction group. 

We have had the pleasure of serving some of the most notable Washington D.C. properties, including:

Government: The White House, D.C. Public Schools, Anne Arundel County, U.S. Geological Survey.

Commercial: Best Buy, Coach Leather, FitBit, St. John Properties, Yellowfin Steakhouse. 

Our Approach

Simply put- we do what we say we will. It is built into our core that what we promise to achieve, we will stop at nothing to do so. 

How We Do It:

In order to fulfill our promise, we do whatever it takes. In order to succeed, the process starts with proper planning. Then, once going, we prepare for the unlikely and believe that when things are tough, we alert you with solutions- not problems.  This is our experience and where it counts.
