As the warmer weather comes, it's time to get your deck ready for another season of outdoor enjoyment. Whether you’re hosting family gatherings, relaxing in the sun, or barbecuing dinner, a well-maintained deck is essential for both safety and aesthetics. Taking the time to prepare your deck for summer ensures that it’s clean, safe, and functional, so you can fully enjoy your outdoor space.

In this article, we’ll walk you through a seasonal maintenance checklist to prepare your deck for the summer. From cleaning and inspecting to sealing and repairing, these steps will help protect your deck, extend its lifespan, and create a comfortable space for outdoor living.

1. Clean Your Deck Thoroughly

Over the winter months, your deck likely accumulated dirt, leaves, moss, and debris that can cause damage if left unchecked. Cleaning your deck is the first and most important step in preparing it for summer. Dirt and organic matter can trap moisture, leading to mould, mildew, and staining.

How to Clean Your Deck:

Sweep: Start with sweeping your deck off to remove loose dirt, leaves, and debris. Pay special attention to the gaps between the boards, as this is where debris can build up.
Wash the Surface: After sweeping, use a garden hose to rinse the deck and remove stubborn dirt. For a more thorough cleaning, use a mild soap or deck cleaner and a scrub brush to remove grime, moss, or algae. For wood decks, make sure to scrub along the grain to avoid damaging the surface.
Power Washing*: If your deck is especially dirty, you can use a power washer to clean it. However, I've put an asterisk beside it because you must be cautious—too much pressure can damage the wood or decking material. Use a wide-angle nozzle and keep the pressure setting low (around 1200 psi). Always keep the nozzle at least 12-18 inches away from the surface to avoid gouging the deck.
Clean Between Deck Boards: Be sure to clean the spaces between the boards where debris can collect. Washing this area out is key. If this debris is left, it can deteriorate the framing.

2. Inspect Your Deck for Damage

Over the winter, temperature fluctuations, snow, ice, and moisture may have caused some wear and tear on your deck. It’s important to perform a thorough inspection to ensure that your deck is safe and secure for summer. Early detection of any damage allows for quick repairs and helps prevent larger, more expensive issues down the road.

Key Areas to Inspect:

Deck Boards: Look for signs of splintering, cracking, or warping. If you find any damaged or rotting boards, replace them immediately to prevent further deterioration and safety hazards.
Nails and Screws: Check for loose nails or screws, which can cause boards to shift or become uneven. Tighten or replace any fasteners that have loosened over the winter.
Support Structure: Inspect the deck’s support system, including joists, beams, and posts, for any signs of damage, rot, or sagging. If you notice any issues, it may be necessary to call in a professional for repairs.
Railings and Stairs: Test the stability of your deck’s railings and stairs. Railings should be sturdy and solid to prevent accidents. Inspect stairs for signs of wear, such as loose steps or weak supports. If any part of the railing or stairs feels wobbly, tighten the screws or replace damaged components.
Hardware: Check for rusted or corroded hardware, such as joist hangers or bolts. Replace any rusted fasteners to ensure your deck remains structurally solid.

3. Remove Any Mould or Mildew

Mould and mildew can develop on your deck, especially if it’s made of wood, due to moisture build up over the winter. If you notice any dark spots or fuzzy growth on the surface, it’s important to remove them before they cause permanent damage.

How to Remove Mould and Mildew:

Use a Molud and Mildew Cleaner: There are special deck cleaners designed to remove mould and mildew. Apply the cleaner according to the manufacturer’s instructions, and use a soft brush to scrub the affected areas.
DIY Solution: If you prefer a natural solution, you can mix equal parts water and white vinegar. Apply the solution to the mouldy areas, let it sit for about 15 minutes, and scrub with a brush.
Rinse Thoroughly: After scrubbing, be sure to rinse the deck thoroughly with water to remove any leftover cleaning product. Leftover residue can attract dirt and make the problem worse.

4. Seal and Stain the Deck (If Necessary)

If your deck is made of wood, applying a protective sealant or stain will help maintain its appearance and protect it from the sun, rain, and other elements. A good sealant will help prevent water damage, while a stain will add colour while providing protection.

When to Seal Your Deck:

Wood Decks: If your deck has a wood surface, you should apply a water-resistant sealant or stain every 1-2 years, depending on the level of wear and exposure to the elements. Sealing is especially important for decks that see a lot of sun or rain, as moisture can lead to wood rot and fading.
How to Apply: Apply the stain or sealant using a paintbrush, roller, or sprayer. Be sure to follow the manufacturer’s instructions on drying times and number of coats needed. Apply in thin, even coats to avoid streaking and brush marks.
Composite or PVC Decks: Do not stain or seal any low maintenance decking. This is not necessary and will void the manufacturer's warranty.

5. Check the Drainage and Clean the Gutters

Proper drainage is important to prevent water from pooling on your deck, which can cause damage to the wood or other materials. Check for any signs of poor drainage around the deck and ensure that the gutters and downspouts are clear of debris.

Gutters: Clean out any leaves, twigs, or dirt that might be blocking water flow. Clogged gutters can cause water to overflow and pool near the base of the deck, which can lead to mould, mildew, or wood rot.
Drainage: Check that the area beneath your deck is free from standing water. If you notice water pooling, consider improving the drainage by adding gravel or adjusting the grade to allow for water run off.

6. Prepare Furniture and Accessories

Finally, get your deck furniture, cushions, and accessories ready for summer. Clean your furniture, check for any damage, and add any new touches to refresh the space for the season.

Clean Furniture: Wash furniture cushions, pillows, and any other accessories, to remove dust, dirt, and stains.
Repair or Replace: Check your furniture for any damage that might have occurred over the winter. If any chairs, tables, or railings are worn out or broken, it’s a good time to replace or repair them before your summer parties.

Conclusion: Ready for a Summer of Enjoyment

By following this seasonal maintenance checklist, you can ensure that your deck is ready for a summer full of relaxation, fun, and outdoor living. Regular cleaning, inspections, and upkeep not only improve the safety and appearance of your deck but also extend its lifespan, allowing you to enjoy your outdoor space for many years.
