Spring Deck Maintenance Tips for Homeowners in Minnesota
Spring Deck Maintenance Tips
From the pros at Pink Construction LLC – Your Local Deck Experts
When the snow melts and the grass peeks through in Minnesota, it’s time to give your deck the attention it deserves. Whether you have a classic wood deck or a low-maintenance composite deck, spring is the perfect time to clean, inspect, and protect your outdoor space before summer cookouts and family hangouts begin.
At Pink Construction, we’ve built and maintained hundreds of decks across Minnesota. Here are our expert-backed spring maintenance tips tailored to both wood and composite decks.
1. Start With a Thorough Inspection
Begin by inspecting your deck for any signs of wear and tear (especially on wood decks). Look for things like loose boards, protruding nails, rot, and any structural issues. You'll want to pay special attention to areas where the deck connects to your home and where stairs meet the ground (also loose railings). On composite decks you'll want to look for cracked or scratched boards, or buildup in grooves. Early detection of problems can prevent costly repairs down the line.
🛠 Tip from Pink: Take photos of any problem areas and address safety hazards first.
2. Cleaning the Deck
For Wood Decks:
Use a wood-safe cleaner or a mix of warm water and gentle soap. Scrub with a stiff-bristle brush and rinse with a garden hose. Avoid pressure washers unless you're experienced—they can damage softwood.
For Composite Decks:
Composite decks are more resistant to stains but still need care. Use a composite-specific cleaner (or mild soap and water). Focus on cleaning debris from board grooves and between planks.
🌱 Eco Tip: Always use biodegradable cleaners—Minnesota lakes will thank you.
3. Addressing Mold and Mildew
Minnesota’s wet springs can lead to mold and mildew, especially in shady spots.
- Mix water with oxygen bleach (not chlorine bleach) and gently scrub affected areas.
- Rinse thoroughly and allow the deck to dry completely.
Just remember composite decks are mold-resistant but not mold-proof. Clean areas under furniture and planters where moisture can get trapped.
4. Sanding for a Smooth Finish (Wood Decks Only)
After cleaning your wood deck, allow it to dry completely. Then, sand the surface to remove any splinters or rough spots. This step not only enhances the deck's appearance but also prepares it for staining or sealing. We recommend using 60 or 80-grit sandpaper for the main deck boards and 80 or 100-grit for handrails (focus on high traffic areas).
🌟Reminder: Never sand composite decking—it can damage the material and void warranties.
5. Staining & Sealing (Wood Decks Only)
Minnesota winters are harsh, so reapplying stain or sealant every 1–3 years is crucial.
- Choose a quality product rated for extreme weather (UV + moisture protection).
- Apply on dry days, and avoid staining in direct sun.
Composite decks don’t need staining or sealing—but they do benefit from regular cleaning and occasional polishing with approved products.
6. Don’t Forget the Hardware & Understructure
- Tighten loose screws and replace rusted fasteners.
- Inspect posts, joists, and beams for rot or shifting.
- Clean out debris around footings to prevent moisture buildup.
🔧 Pro Tip: Composite decks may hide structural issues underneath—always check below.
7. Prevent Future Damage
- Trim nearby trees and shrubs to increase sunlight and airflow.
- Use furniture pads to prevent gouging or rust rings.
- Move planters and rugs around to avoid trapped moisture or discoloration.
☀️ Minnesota Bonus Tip: Add a pergola or shade structure to extend your deck’s life by shielding it from sun and snow.
