Why Deck Skirting Fails in Coastal Virginia

The Hidden Problems Most Homeowners Never See

Deck skirting is often treated as a cosmetic feature — but when built incorrectly, it becomes one of the fastest ways to destroy a deck from the ground up.

At B&B Decks, we inspect failed decks throughout Hampton Roads every year. One of the most common contributors to premature deck failure is improperly designed or poorly installed deck skirting.

In coastal Virginia, moisture, humidity, and ground conditions make skirting failures even more likely when shortcuts are taken.

1. Lack of Proper Ventilation

The most common skirting failure we see is a complete lack of ventilation. Solid skirting panels trap moisture beneath the deck, creating a damp environment that accelerates rot, mold growth, and corrosion of fasteners.

Without airflow, even pressure-treated lumber will fail prematurely.

2. Skirting Installed Too Close to the Ground

Skirting that is installed directly against soil or too close to grade absorbs moisture continuously. This leads to:

• Rot at the bottom of skirting boards
• Insect and pest intrusion
• Trapped organic debris beneath the deck

Proper ground clearance is not optional — it is critical for longevity.

3. Using the Wrong Materials

Many skirting failures occur when materials meant for trim or interior use are installed in ground-adjacent exterior environments.

In coastal Virginia, skirting materials must withstand:

• Constant humidity
• Splashback from rain
• Salt air corrosion

4. No Access for Inspection or Maintenance

Completely sealed skirting systems without access doors prevent homeowners and contractors from inspecting framing, drainage, and pest activity.

By the time a problem becomes visible, structural damage is often already severe.

5. Treating Skirting as an Afterthought

Skirting is often added after a deck is complete without considering airflow, drainage, or structural impact.

Skirting should be designed as part of the deck system — not attached as a cosmetic add-on.

How to Prevent Deck Skirting Failure

Proper skirting design starts with understanding how decks actually fail. At B&B Decks, we build skirting systems that:

• Include intentional ventilation openings
• Maintain required ground clearance
• Use materials appropriate for coastal exposure
• Allow access for inspection and maintenance
• Integrate seamlessly with deck framing

Built the Right Way from the Start

If you’re considering privacy or horizontal deck skirting, make sure it’s designed to protect — not shorten — the life of your deck.
