Seasonal Maintenance Calendar for Hardwood Decks

Introduction

Tropical hardwood deck maintenance isn't complicated, but it is time-sensitive. Doing the right tasks at the right time of year keeps your deck protected year-round and extends the time between major restoration projects. This seasonal calendar covers all four seasons for Ipe, Cumaru, Garapa, and other tropical hardwood decks.

Key Takeaway: Spring is the most important season for deck maintenance — clean and oil after winter, and conduct your annual structural inspection before peak use season.

Spring (March–May): The Most Important Season

Late March – Early April: Annual Inspection This is the time to conduct your complete annual structural inspection. Check posts, beams, ledger board, hardware, and railings after winter stress.

April–May: Clean and Oil Once temperatures are consistently above 50°F and rain is not forecast:

1. Clean the deck surface — see our cleaning guide
2. Allow 48 hours to dry
3. Apply deck oil — see our oil application guide

This is the most critical oil application of the year — it prepares the deck for summer UV and heat exposure.

Summer (June–August): High Use Season

Monthly: Light Cleaning Remove debris, leaves, and any accumulated dirt from between boards. Keep board gaps clear for drainage.

After Parties/Events: Rinse the deck with water to remove food residue. Address any stains promptly — most hardwood stains clean up easily when fresh.

July–August (Coastal Decks): If you're in a coastal environment, your second oil application of the year may fall in late summer. Check whether water is still beading on the surface — if not, it's time to re-oil.

Fall (September–November): Preparation Season

September–October: Optional Second Oil Application In cooler climates or for decks in full sun, a fall oil application extends protection through winter. Apply before temperatures drop below 50°F.

November: Winter Prep

• Clear leaves and debris — trapped organic matter accelerates surface degradation
• Move planters to prevent soil moisture contact with deck boards
• Stow deck furniture or use furniture covers
• Check that drainage from gutters and downspouts doesn't direct water onto the deck

Winter (December–February): Monitoring Season

Ongoing: Remove Snow Promptly Use a plastic shovel — never metal blades. See our ice damage prevention guide for winter care specifics.

Periodically: Check for Debris Wind carries debris onto decks in winter. Leaves and organic matter that freeze into the deck surface can stain boards.

February: Planning Season Order replacement boards, fasteners, or deck oil now to have materials ready for spring maintenance.

FAQ

Do I need to oil twice a year?

For most inland climates with normal sun exposure, once annually (spring) is sufficient. Coastal environments, decks in full sun, or lighter-colored species like Garapa benefit from twice-yearly oiling.

What if I miss a year of oiling?

Missing one year is not catastrophic for dense tropical hardwoods like Ipe. The wood will begin to gray, but a thorough cleaning and fresh oil application will restore it. Multiple missed years may require sanding before refinishing.
