Deck Maintenance Mistakes You're Probably Making (and How to Fix Them)

Introduction

Your deck is an extension of your home, a place for relaxation, entertainment, and enjoying the great outdoors. But all that exposure to the elements takes a toll. Many homeowners unwittingly make deck maintenance mistakes that can lead to costly repairs, structural damage, and even safety hazards. Whether your decking is wood, composite, or PVC, proper care is essential to ensure its longevity and beauty. This guide will walk you through common pitfalls and provide practical solutions to keep your deck in top condition for years to come. Let's dive into the world of decking maintenance!

Main Content

1. Neglecting Regular Cleaning:

Perhaps the most common decking mistake is failing to clean it regularly. Dirt, grime, algae, and mildew accumulate over time, creating a slippery surface and providing a breeding ground for decay.

• The Problem: Organic matter retains moisture, promoting rot, discoloration, and even insect infestations.
• The Solution: Clean your deck at least twice a year – in the spring and fall. Use a stiff brush and a deck cleaning solution specifically designed for your decking material. For stubborn stains, consider using a pressure washer, but exercise caution! Hold the nozzle at a wide angle and maintain a safe distance to avoid damaging the surface. For composite decking, follow the manufacturer’s recommendations for cleaning solutions.

2. Ignoring Small Cracks and Splinters:

Small cracks and splinters may seem insignificant, but they can quickly escalate into larger problems.

• The Problem: Water seeps into these crevices, causing the wood to expand and contract, further widening the cracks and leading to structural damage.
• The Solution: Regularly inspect your decking for cracks and splinters. Use wood filler to repair small cracks in wood decks. For larger cracks, consult a professional. Sand down splinters and apply a sealant to prevent them from returning.

3. Improper Sealing or Staining:

Sealing or staining your deck protects it from moisture, UV rays, and everyday wear and tear. However, applying these products incorrectly can do more harm than good.

• The Problem: Applying sealant or stain to a dirty or damp deck can trap moisture, leading to rot and peeling. Using the wrong type of sealant or stain can also be detrimental.
• The Solution: Thoroughly clean and dry your deck before applying any sealant or stain. Choose a product specifically designed for your decking material and climate. Apply thin, even coats and allow ample drying time between coats. Always follow the manufacturer's instructions. For composite decking, some require specific types of sealant.

4. Overlooking Fastener Issues:

Screws and nails are essential for holding your deck together. Ignoring loose or corroded fasteners can compromise the structural integrity of your deck.

• The Problem: Loose fasteners allow the decking boards to move, creating tripping hazards and weakening the overall structure. Corroded fasteners can stain the decking and eventually break.
• The Solution: Regularly inspect your deck for loose or corroded fasteners. Tighten loose screws or replace them with new ones. Replace corroded nails with stainless steel screws.

5. Improper Drainage and Ventilation:

Adequate drainage and ventilation are crucial for preventing moisture buildup and promoting airflow around your deck.

• The Problem: Poor drainage can lead to standing water, which promotes rot and algae growth. Inadequate ventilation restricts airflow, trapping moisture and creating a damp environment.
• The Solution: Ensure that your deck is properly sloped to allow water to drain away. Clear any debris that may be blocking drainage pathways. Consider installing ventilation grates or modifying the deck structure to improve airflow. If you're planning new decking, prioritize proper drainage in the design.

6. Neglecting the Substructure:

The substructure is the foundation of your deck, and neglecting it can lead to serious problems.

• The Problem: Rot, insect infestations, and structural damage to the substructure can compromise the safety and stability of your entire deck.
• The Solution: Inspect the substructure regularly for signs of damage. Ensure that the joists, beams, and posts are properly supported and protected from moisture. Consider hiring a professional to perform a thorough inspection and make any necessary repairs.

7. Using Harsh Chemicals or Abrasive Cleaners:

While cleaning is important, using the wrong products can damage your decking.

• The Problem: Harsh chemicals can discolor, etch, or weaken the decking material. Abrasive cleaners can scratch the surface and remove protective coatings.
• The Solution: Avoid using bleach, ammonia, or other harsh chemicals on your deck. Opt for deck cleaning solutions specifically designed for your decking material. Use a soft-bristled brush or sponge to avoid scratching the surface.

8. Ignoring Local Building Codes:

Building codes exist to ensure the safety and structural integrity of your deck. Ignoring them can lead to fines, safety hazards, and even the need to rebuild your deck.

• The Problem: Building codes dictate the proper spacing of joists, the size of posts, and other structural requirements. Failing to comply with these codes can compromise the safety of your deck.
• The Solution: Familiarize yourself with local building codes before undertaking any deck repairs or renovations. If you're unsure, consult with a building inspector or a qualified contractor.

9. Placing Heavy Objects Incorrectly:

Distributing weight evenly across your deck is crucial for preventing structural problems.

• The Problem: Placing heavy objects, such as hot tubs or large planters, in a concentrated area can overload the deck structure and cause it to sag or collapse.
• The Solution: Distribute the weight of heavy objects evenly across the deck. Consider adding additional supports or reinforcing the deck structure before placing heavy items.

10. Failing to Prune Nearby Vegetation:

Overhanging trees and shrubs can contribute to moisture buildup and debris accumulation on your deck.

• The Problem: Fallen leaves, twigs, and other debris can trap moisture and promote rot. Shady conditions can also encourage algae and mildew growth.
• The Solution: Regularly prune nearby trees and shrubs to allow sunlight and air to reach your deck. Remove any debris that accumulates on the surface.
