To help you maintain your outdoor space, we’ve put together the ultimate guide to deck care. Follow these do’s and don’ts to protect your investment and keep your deck looking its best!

✅ The Do’s of Deck Maintenance

Taking the right steps in deck care will prevent costly repairs and extend the life of your deck. Here’s what you should be doing:

1. Keep It Clean and Tidy

Dirt, leaves, and other debris can accumulate on your deck, leading to mold, mildew, and discoloration. Regular sweeping and occasional washing with mild soap and water will help maintain its appearance and prevent long-term damage.

2. Power Wash Your Deck (Gently!)

A power washer can be a great tool to remove built-up grime, but be sure to use a low-pressure setting. Too much pressure can strip away finishes, damage wood fibers, and even cause splintering. If you’re unsure, test a small, inconspicuous area first.

3. Use Outdoor Mats Under Furniture

Furniture legs can scratch or dent your deck over time. Using outdoor mats or protective pads under tables and chairs will help prevent wear and tear. Additionally, mats can catch spills and prevent stains from food, drinks, or potted plants.

4. Tighten Any Loose Screws or Nails

Over time, screws and nails can loosen due to weather changes and regular foot traffic. Regularly inspect your deck for any protruding fasteners and tighten or replace them as needed to maintain stability and prevent accidents.

5. Schedule an Annual Inspection

A yearly deck inspection helps identify potential problems before they become expensive repairs. Check for signs of rot, cracks, or structural weaknesses, especially in areas where the deck connects to your home. If needed, consult a professional for a thorough assessment.

❌ The Don’ts of Deck Maintenance

Avoiding these common mistakes will help prevent damage and keep your deck in great condition:

1. Don’t Let Moisture Linger

Water is one of the biggest threats to a deck’s longevity. Standing water can lead to mold, mildew, and wood rot. After rain or cleaning, ensure your deck dries properly by keeping it well-ventilated and removing puddles.

2. Don’t Pressure Wash on a High Setting

A high-pressure setting might seem like a quick way to clean your deck, but it can do more harm than good. Excessive pressure can damage the wood’s surface, strip away protective finishes, and create splinters. Always use a moderate setting or consider using a garden hose with a sprayer attachment instead.

3. Don’t Use Bleach or Chlorine-Based Cleaners

While bleach may seem like an effective way to kill mold and mildew, it can actually weaken the wood and cause discoloration. Instead, opt for a deck cleaner specifically designed for wood or composite decking.

4. Don’t Place Hot Objects Directly on the Surface

Heat from grills, fire pits, or hot pans can scorch or warp your deck’s surface. Always use a heat-resistant pad or a grill mat to protect the wood from extreme temperatures.

5. Don’t Neglect the Sealing

Sealing your deck is crucial to protecting it from moisture, UV rays, and general wear and tear. If your deck is made of wood, reapply a high-quality sealant or stain every 1–3 years, depending on exposure to the elements. Without proper sealing, your deck is more susceptible to cracking, splintering, and fading.

6. Don’t Use Harsh Chemicals

Strong cleaning agents, including ammonia-based or acidic cleaners, can strip away sealants and damage the deck’s surface. Always check product labels and choose a cleaner that is safe for your specific deck material.

Additional Tips for Long-Lasting Deck Care

• Trim surrounding vegetation – Overgrown bushes and trees can trap moisture against your deck and encourage mold growth. Keep plants trimmed back to allow for proper airflow.
• Move furniture and rugs periodically – Leaving furniture or outdoor rugs in the same spot for too long can cause uneven fading and moisture buildup underneath. Shift them occasionally to maintain an even appearance.
• Protect against pests – Termites and other wood-boring insects can cause serious damage. Consider applying a protective treatment or consulting a pest control expert if you notice any signs of infestation.
• Remove snow and ice carefully – If you live in a colder climate, use a plastic shovel to clear snow from your deck. Avoid using salt or ice melt, as they can damage wood and corrode fasteners.

Maintaining your deck doesn’t have to be overwhelming! By following these do’s and don’ts, you’ll ensure your outdoor space remains a beautiful, safe, and enjoyable place for years to come.
