Our quality service and keen eye for detail provides outstanding results. Let our team build your dreams with our in-house designers we bring your dreams to life. Call Colbyco Custom Construction, LLC, today for your professional consultation.
"I have delt with a lot of bad contractors in my life and Colbyco is the absolute worst! The communication between father and son was horrible. I was supposed to work with the father and he didn't share with the son what I wanted to happen. He lives on the other side of the state and was trying to direct the project from there which was a joke. Everything that could go wrong did go wrong and two years later I'm still living with the horrible work that they did. If you don't have any idea about what you want and leave everything in their hands then fine, but if you want something custom, to your own specifications, forget it. They will do whatever they want and won't fix it later. Run, Run, Run away from this company!"

"Levcor has truly surpassed our expectations with its exceptional craftsmanship and commitment to bringing our vision of a dream kitchen to life. What began as a casual conversation a few years ago has now become a reality, thanks to their deep knowledge of kitchen functionality, and their ability to see what the end result can be throughout the design process. Their meticulous attention to detail and dedication helped us make the most of our space and create a design we could never have imagined. Working alongside Mike Sawyer has been a remarkable experience. He perfectly balanced our aspirations with our budget, making the entire process seamless. Mike's guidance empowered us to explore various design options, reimagining our space while staying within our scope and budget. His foresight even saved us a significant amount on kitchen cabinet costs due to an impending 30% lumber price increase. Despite their extensive experience, Levcor maintains the warmth and attentiveness of a family-run business. Their genuine care and responsiveness echoed throughout every interaction and made us feel valued and understood at every stage of the project. Furthermore, the professionalism displayed by both the business owner and the contractors was commendable. Their commitment to delivering outstanding results while maintaining efficiency was evident in the timely completion of our project. The attention to detail was truly exceptional, blending functionality with aesthetics to create a kitchen that not only met but exceeded our expectations, taking a disjointed space and helping redefine it. What started as a small, cramped kitchen, is now an expansive space for baking or a casual meal and a conversation. We went from a glass cooktop and single electric oven to a 5-burner gas range, double oven, and even a proofing/warming drawer. In summary, Mike's exemplary work ethic, expertise, and genuine care make him an outstanding contractor. For anyone considering a significant home renovation project, like a kitchen remodel, Levcor's proficiency and personal touch promise a transformative experience, resulting in a space you'll treasure for years to come. Trust me on this, as our remodeled kitchen has provided my wife with the perfect 9-foot island to launch her small gluten-free baking business."

FAQs for addition to existing structure building service projects in Oregon City, OR
Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take.
Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite.
An in-law suite is a self-contained living space attached to—or detached from—your main home. Expect a bedroom, full bath, and a kitchenette or compact living area. The setup gives relatives privacy, doubles as a potential rental, and can lift your property value. To qualify as a legal dwelling, the suite must meet local building codes and zoning rules.
