Understanding the Professional Cost to Restain a Deck

For construction professionals, knowing the precise cost to restain a deck is crucial for accurate project planning. In 2025, the average cost for professional deck restaining ranges from $3 to $6 per square foot. For a 300 sq ft deck, this translates to $900–$1,800. These figures depend on various factors, which we will explore in detail.

Average Cost Range in Construction

Professional restaining costs in California typically range between $3 and $6 per square foot. For a 300 sq ft deck, expect to pay between $900 and $1,800. These costs can vary based on several factors:

Typical Expense Breakdown

• Labor: 60 – 70% of total cost, covering preparation, sanding, and application.
• Materials: 20 – 25% for premium stain, brushes, and sprayers.
• Repairs & prep extras: 5 – 15% for board replacement or mildew treatment.

Key Cost Drivers in Deck Restaining

1. Deck Size & Footprint

Larger decks require more materials and labor, increasing costs.

2. Railing & Baluster Density

Complex rail systems can significantly increase labor time.

3. Previous Coating Type

Oil-based stains are easier to strip than thick paints, affecting prep costs.

4. Wood Species & Condition

Softwoods like redwood absorb more stain, while aged cedar may need extra care.

5. Height & Accessibility

Higher decks require additional safety measures, impacting labor costs.

6. Regional Labor Market

Labor rates in areas like San Francisco are higher than in other regions.
