Highline Builders Construction

In 1979, Steve Winkler built a business.
This business was a one man job to start. Steve ran the business on his own, doing everything from supervising the jobsites to the paperwork behind the scenes. Small projects such as remodels and add-ons turned into building from the ground up. With all of the business coming together, Steve kept one motto in mind with every job: we build dreams big and small.

Born and raised right in Sebastopol, CA, he knew the importance of hard work, a skill learned from his childhood working on a dairy farm. The ranch was a family business, giving Steve a strong sense of the importance of family. Keeping that theme in mind, Highline has and will always be a family business.

In 1997, the small business added to the family. Steve’s daughter, Jodie, married an Idaho-raised man, Tyler, who shared the same love for family and appreciation for hard work. In 2003, Steve and Tyler turned this small business into a corporation. Steve being the Founder and President and Tyler standing beside him as Vice President, with Tyler running the on-site part of the business.

But that’s not where the family employees end. Jessica Lomanto, Steve’s oldest daughter, took on the responsibilities of the office work, bringing even more organization to the growing business. Jodie brings her eye for design to each project, giving every job a unique style allowing every homeowner’s dream come together. Today, Steve's vision continues to expand, as his oldest grandson has taken to learning the ropes on jobsites and expanding his building skills.

Even though he didn’t know it at the time, Steve created the building blocks for this beautiful family business that continues to truly build dreams big and small.

Though the main office is located in Sebastopol, CA, Highline builds beautiful homes all over the North San Francisco Bay. Santa Rosa, Sonoma, Napa and beyond have had owners able to build their dreams with Highline’s help.

    Kitchen and Bathroom remodel
    $25,000
    45 days

    My 100 year old home was remodeled by Steve and the crew at Highline, and we found the quality of work to be very good, and the crew very professional working in our home. The thing we remember most, and valued highly, was their willingness to present us with different ideas and alternatives to our project, to give us both costs savings and different design ideas. You just don't get that from any contractor today!! Thank you to the staff and crew at Highline Builders for a job well done!
