Superior’s flat, low lying geography keeps groundwater closer to the surface than in hillside Duluth, and that proximity affects deck footings in ways many contractors overlook. Homes throughout East End and Billings Park often have decks installed decades ago without footings deep enough to resist the frost heave this water table creates every winter. Harbor wind exposure adds another layer of stress, pushing against deck structures with a force flatter, more open Superior lots experience more directly than sheltered inland properties. Perrault Construction has built and repaired decks throughout Superior for years, engineering footings and structures for the specific groundwater and wind conditions this harbor city presents.
We build Superior decks with footings engineered for the region's high water table, preventing the frost heave that compromises shallow installations.
Older Superior decks often show foundation shifting caused by groundwater and frost heave. We repair these structural issues at the source.
Harbor humidity wears down deck surfaces throughout Superior. We resurface and refinish to protect against ongoing moisture exposure.
We reinforce railings and posts on Superior's historic homes, bringing decades old structures up to current safety standards.
Harbor wind exposure brings fast, direct storm impact to Superior properties. We respond quickly to restore damaged decks.
The city's low elevation keeps groundwater closer to the surface, making frost heave a more significant factor in footing stability.
Yes, Perrault Construction holds full licensing in both Wisconsin and Minnesota.
Footing depth depends on soil and water table conditions at your specific property, which we assess during every project.
Most projects take one to three weeks depending on size and site conditions.
Yes, Superior's flat, open geography allows harbor wind to impact deck structures more directly than sheltered inland properties.
Yes, we regularly reinforce historic deck structures to meet current safety and structural standards.
Yes, flexible financing is available for new construction, repair, and resurfacing projects.
A full inspection of your deck or planned site along with a detailed cost breakdown at no charge.
We prioritize storm response and typically schedule assessments within days of contact.
Soft or rotting boards, loose railings, wobbling posts, and visible shifting all indicate it is time for a professional inspection.
