Decks That Withstand Duluth’s Climate
Duluth homeowners face long winters, heavy snow, and moisture from Lake Superior. We build decks with proper drainage, reinforced supports, and moisture barriers to prevent rot and collapse. Our materials are chosen for resilience against snow, ice, and rapid freeze-thaw cycles, giving you a deck that lasts through every season.
Outdoor Living, North Shore Style
Covered Decks, Porches & Outdoor Kitchens in Duluth
Life in Duluth calls for outdoor spaces that work in every season. That’s why we design covered decks that provide shade in summer and shelter from snow in winter. Screened porches keep out mosquitoes while extending your living area, and our outdoor kitchens make lakeside entertaining easy. Each project is tailored to fit your home’s layout and the rugged beauty of the North Shore.
