Onekama Contractor

Onekama sits at the outlet of Portage Lake where it meets Lake Michigan, and the housing stock reflects decades of seasonal use followed by a growing push toward year-round occupancy. Many properties in this area started life as summer cottages — lightly insulated, built on minimal foundations, with deferred maintenance that accumulates over years of seasonal-only attention. Converting these into functional year-round homes involves real structural and envelope work: proper foundations, insulated walls and roofs, energy-rated windows, and upgraded entry systems.

Gerhard & Sons handles this kind of conversion work regularly in the Onekama area. We assess what a seasonal structure actually needs to perform through a full Michigan winter, and we do the work in the right order — foundation and framing before finishes, envelope before mechanicals. We also work with full-time homeowners on standard roofing, siding, deck, and remodeling projects throughout the community.
