Common Issues with Deck Boards
Decking boards are the heart of your deck. They’re the surface that allows you to enjoy family meals outdoors, entertain guests, and have the big BBQ that people talk about for the next month. Decks are a great way to spend time outdoors! Unfortunately, even when the gatherings are over, your deck continues to spend time outdoors where it’s subject to wind, rain, snow, branches, algae, and more. Over time, these boards can experience a range of issues that compromise the safety, appearance, and functionality of your outdoor space. At Cardinal Exteriors, we’ve seen it all, so let’s explore the most common problems decking boards face and how to address them effectively.
1. Wood Rot and Decay
The Problem:
Wood decking, particularly untreated or older boards, is vulnerable to moisture. Rain, snow, and even morning dew can seep into the wood fibers, creating the perfect environment for rot and decay. Left unchecked, rot can spread and weaken the structural integrity of your deck.
How to Fix It:
Let Cardinal identify and replace any rotted boards immediately.
Cardinal can use pressure-treated or naturally rot-resistant wood (like cedar or redwood) for replacements.
Apply a high-quality waterproof sealant to prevent future moisture penetration.
2. Splintering and Cracking
The Problem:
Over time, exposure to sunlight, temperature changes, and foot traffic can cause wood boards to dry out and splinter. Cracks not only affect the aesthetics of your deck but can also create safety hazards, especially for children or pets. You REALLY don’t want someone’s leg or body going through a deck (especially a raised deck) due to weak boards.
How to Fix It:
Fill small cracks with an exterior-grade wood filler.
Have Cardinal repair or replace severely cracked boards to ensure safety and longevity.
Regularly stain or seal wood to protect it from drying out and cracking.
3. Fading and Discoloration
The Problem:
The sun’s UV rays can cause wood and composite decking to lose their original color, leaving your deck looking weathered and dull. In some cases, spills or standing water can create unsightly stains.
How to Fix It:
Clean the deck with a specialized cleaner to remove dirt and stains.
For wood decks, apply a fresh coat of stain to restore color and protect against UV damage.
For composite decking, follow the manufacturer’s cleaning and care guidelines to address discoloration.
Consider installing a pergola or shade structure to protect your deck from direct sunlight.
4. Loose or Warped Boards
The Problem:
Decking boards can loosen over time due to fluctuating temperatures, moisture, or simply wear and tear. Warping, where boards bend or twist, is another common issue caused by improper installation or prolonged exposure to moisture.
How to Fix It:
Tighten screws or replace nails that have worked loose.
If a board is warped, try re-securing it. If that doesn’t work, replace it entirely.
Ensure proper ventilation beneath the deck to minimize moisture build-up, which can lead to warping.
Use screws instead of nails when installing new boards to ensure a firmer hold.
5. Mold, Mildew, and Algae Growth
The Problem:
Damp and shaded areas of your deck can become breeding grounds for mold, mildew, and algae, leaving your boards slippery and unsightly.
How to Fix It:
Regularly clean the deck with a pressure washer or scrub with a mixture of water and mild detergent.
For persistent mold or algae, use a specialized cleaner designed for your decking material.
Ensure proper drainage and ventilation around your deck to reduce moisture build-up.
6. Popped Nails and Screws
The Problem:
Over time, nails or screws securing the boards can work their way out due to expansion and contraction caused by temperature changes. These protrusions not only look bad but can also cause tripping hazards.
How to Fix It:
Hammer down popped nails or replace them with screws for a more secure hold.
Consider replacing nails with deck screws or hidden fasteners to avoid future issues.
7. Peeling or Chipping Finishes
The Problem:
Paints, stains, and sealants can peel or chip due to age, poor application, or harsh weather conditions, leaving your deck exposed to the elements.
How to Fix It:
Strip any peeling finishes with a deck stripper or sander.
Apply a fresh coat of paint, stain, or sealant, ensuring the surface is clean and dry beforehand.
Use products specifically designed for outdoor use to improve durability.
Preventative Tips to Keep Decking Boards in Great Shape
Regular Maintenance: Clean your deck at least twice a year to remove debris, dirt, and mildew.
Seal and Stain: Apply a high-quality sealant or stain every 2–3 years to protect wood decking.
Check Fasteners: Inspect screws and nails regularly to ensure they’re secure.
Protect Against Moisture: Ensure your deck has proper drainage and avoid placing rugs or mats that trap moisture.
