Columbia Contracting LLC

Great pricing and great work communication was great and work was done in one day. Would recommend to anyone.

Columbia Contracting did an outstanding job replacing our roof. From start to finish, they were professional, friendly, and communicative. They provided detailed quotes, answered all our questions, and completed the work on time. Erwin went above and beyond to ensure they exceeded expectations. We truly appreciated their transparency and reliability. Highly recommend them for any roofing project!

After interviewing seven roofing companies, I chose Columbia Contracting LLC and I’m so glad I did. What set them apart was that the owner, Erwin Serrano, personally came out to provide the estimate instead of sending a salesperson. He respected my time, clearly laid out my options, and never pressured me—unlike other companies that spent over an hour trying to convince me to choose them. Erwin was professional, thorough, and communicative throughout the entire process. He used a drone to show detailed pictures of the roof, including the rotten boards that needed replacing, which gave me peace of mind and full transparency. The installation was completed in just one day, and the crew was efficient, respectful, and cleaned up well. Erwin even returned the next day for a final walkthrough to ensure everything was done right. If you're looking for quality, professionalism, and integrity, I highly recommend Columbia Contracting LLC.

Incredibly professional and responsive and always does a great job! They also strive to work around your schedule!

Another fantastic experience with Columbia Contracting! This time we added a sunroom, 12x12' and it came out great! Very fair pricing. Excellent communication as always and the whole crew is friendly, professional, dependable and completely dedicated to the project, start to finish. We will definitely be calling them back in the future for more projects. 😊
