Minnesota's weather is tough on decks. From summer UV exposure to winter freeze-thaw cycles, your deck needs regular care to stay safe and beautiful. Here's a seasonal maintenance guide.
Spring: Assessment and Cleaning
After winter, your deck needs attention:
• Inspect for Damage: Check for loose boards, popped nails, rotting wood, and structural issues.
• Clear Debris: Remove leaves and debris trapped between boards that can trap moisture.
• Deep Clean: Use a deck cleaner appropriate for your material (wood, composite, or PVC).
• Check Hardware: Tighten loose screws and replace any that are stripped or corroded.
Summer: Protection
With your deck clean, it's time to protect it:
• Stain or Seal Wood Decks: Apply a quality stain or sealer every 1-3 years depending on exposure and product.
• Address Mildew: Summer humidity can promote mold and mildew. Treat problem areas promptly.
• Move Planters: Don't leave containers in one spot all season—they trap moisture and can cause staining or rot.
Fall: Preparation
Get ready for winter:
• Final Cleaning: Remove fallen leaves regularly before they become a soggy, staining mess.
• Check Drainage: Ensure water can flow away from your deck and doesn't pool.
• Store Furniture: Move or cover furniture to protect both the furniture and the deck beneath it.
Winter: Careful Snow Removal
• Use Plastic Shovels: Metal shovels can scratch and gouge deck surfaces.
• Shovel With the Boards: Push snow parallel to boards, not across them.
• Avoid Salt: Most ice melt products damage wood and composite materials. Use sand for traction if needed.
Wood vs. Composite Care
Wood decks require more maintenance (regular staining/sealing) but can be sanded and refinished. Composite decks are lower maintenance but require specific cleaners and can't be refinished if damaged.
When to Call Professionals
If you notice significant rot, structural sagging, or widespread damage, it's time for professional assessment. Small repairs now prevent costly replacements later.
