"The Koeppen brothers took both the design and construction of our small remodel so seriously.  They were respectful of our timing needs, and have a serious work ethic and finely detailed carpentry skills.  We're very happy with what they did and plan on using their help again."

"GJ Koeppen Construction managed the highest level of customer service and customer satisfaction I have experienced in many years!  Your professionalism, attention to detail, and routine follow-up and feedback, has taken a challenging situation and turned it into a positive experience."

"…We really liked working with Graham and Joel.  We felt like they approached our project as if it were their own home.  They really demonstrated a desire to make things the way they’d want them to be if they were going to be living here.  When I accidentally scratched up the new floor right after they finished it, I was more concerned about their disappointment than what it was going to cost to fix. Their pride in their work translated into a house that we are very proud of."

"We talked with a lot of contractors before them and several of them annoyed or intimidated us.  We wanted to work with someone who we felt comfortable with. Even though we are very happy to have our house back to ourselves, we liked having them here during the project."

 Rob and Ashleigh, Boulder

"GJ Koeppen Construction has completed construction projects of several types for me. From a full remodel of an old and difficult little house to my own personal master bathroom.  They are competent and flexible.  In addition to being competent they built things exactly how I wanted them without imposing what they thought I should do.  We always discussed the cost of changes, which can be a serious source of discontentment for both parties.  They are easy to work with and make every effort possible to finish according to the construction timeline and budget."
