Mac Grove Painting has worked across the St. Croix River valley long enough to recognize what makes Troy’s housing stock distinct from much of the Twin Cities metro — and what it demands from exterior paint work. This is rural St. Croix County terrain: rolling land, dense tree canopy, properties spread across valleys where moisture lingers and sunlight reaches some walls only briefly. The homes here weren’t built for curb appeal in a suburban sense. They were built to last, and the paint work needs to match that ethic.
The most common structures we encounter in Troy are late 19th and early 20th century farmhouses — Folk Victorian builds with gable-front rooflines, asymmetrical facades, and Victorian detailing that rewards careful preparation before any coating goes on. Wood siding and masonry on these older structures has often been through decades of freeze-thaw cycles, and the porches and gabled additions that characterize so many of them trap moisture in ways that punish shortcuts. Ranch homes from the 1950s present a different set of considerations: low-pitched roofs and horizontal profiles that collect standing water along soffits and trim, especially on north-facing exposures where shade keeps things damp well into the afternoon.
Exterior Painting in a Humid, Shaded Landscape
Troy’s geography shapes every exterior painting decision. Properties near the St. Croix River corridor deal with elevated humidity, and lower-level siding on homes in the valleys can face real moisture exposure during wet seasons. Mildew-resistant finishes aren’t optional here — they’re the baseline. Shaded north-facing walls need primers and topcoats formulated to adhere in conditions where surfaces dry slowly and biological growth is a persistent issue. Getting the coating system right for these conditions matters more than brand name or color choice.
Steeper pitches on Folk Victorian rooflines and wrap-around porch ceilings require paints that hold up to the particular stress of Minnesota and western Wisconsin winters — surface expansion and contraction, ice accumulation along edges, and the UV degradation that comes with open exposure on south and west elevations. Brick and masonry farmhouses in Troy call for breathable, masonry-compatible coatings that allow moisture vapor to escape rather than trap it behind a film that eventually fails.
Interior work in these older rural homes often means navigating plaster walls, original woodwork, and rooms that have seen several generations of paint layered over each other. The preparation — skim coating, careful sanding, understanding what’s underneath — is where that work either holds or doesn’t. Mac Grove approaches these projects with the same deliberateness we bring to a 1920s craftsman bungalow in Saint Paul’s Mac-Groveland neighborhood, because the underlying principles are the same even when the architecture differs.
Troy is not a place where generic painting approaches translate well. The combination of historic rural architecture, a challenging microclimate along the river valley, and properties that often sit in deep shade or exposed hillside positions means the work has to be site-specific and material-specific. That’s the kind of painting we do.
