About Oshkosh & Why Our Work Lasts Here

Oshkosh’s position on Lake Winnebago creates one of the more demanding humidity environments in Northeast Wisconsin. Summer months bring high moisture from the lake, and interior humidity stays elevated well into fall β€” then drops sharply in winter when heating systems run. That cycle is particularly challenging for solid wood trim: boards absorb moisture in summer and swell slightly, then dry and contract in winter, opening gaps at miters and joints if the work wasn’t done with Wisconsin’s climate in mind.

In the Riverfront and Algoma neighborhoods, where lakefront properties and older homes sit close to the water, we prioritize paint-grade MDF trim for flat surfaces and finger-jointed pine for profiles β€” materials that are more dimensionally stable than solid clear pine in high-humidity environments. For cabin renovations in the Westside and lakefront areas, where the goal is often a quick Airbnb-ready refresh before EAA AirVenture season, we focus on high-impact upgrades: new baseboard and casing throughout, a wainscoting accent wall, and a clean painted fireplace surround. Those details photograph well and add genuine perceived value for rental guests.
