JAM3 Builders

JAM3 Builders is a concrete and carpentry contractor run by Tony Fettkether, a family-owned business in Rohnert Park. The company pours foundations, patios, driveways and walkways, and does concrete repair and sealing. On the carpentry side it builds decks and porches, fences and gates, stairs and ADA ramps, and wood pergolas and arbors, along with deck and fence repair.

Work starts with an in-person consultation at your property, followed by a detailed written estimate covering materials and labor. Free estimates are offered, and once you approve, the crew confirms a start date. The company serves Rohnert Park, Santa Rosa and across Sonoma County.
