The Bay Area’s #1 Eichler Remodeling Contractor, and More
Keycon began as Key Construction in the Palo Alto area in the early ’80s when Ron Key—who had worked in residential construction for ten years—launched his own business as a sole proprietor. In 2006, Ron incorporated Keycon, Inc., and today Keycon is known as the Bay Area’s leading Eichler construction remodeling contractor. Keycon has renovated more Eichler homes than any other Bay Area contractor.
Keycon’s Design-and-Build Advantage
Keycon offers design-and-build services that help you visualize both the possibilities and practicalities of your remodeling project. Each project is customized to your requirements.
An elegant new modern kitchen by Keycon
And it all starts with a free consultation where you can ask one of the most important questions in remodeling: What If?
“What if we move this wall? …use a different finish? …or choose a different countertop material?”
By working with one team to design and build, you get the remodeling results you always imagined while avoiding costly construction snags.
