How much does it cost to stain a wood deck?

Maintaining a wood deck periodically involves staining to preserve its appearance and durability against the weather in Quebec. The price varies depending on the surface area to be covered, the condition of the wood, and whether you hire a professional or do the work yourself. Here's an overview of average costs in Canada.

Average cost for a professional

Hiring a pro to stain a well-maintained deck will generally result in a bill between $1.75 and $4.50 per square foot. This rate includes:

• Inspection: Assessment of the deck's overall condition and recommendation of the type of stain.
• Preparation: Light brushing or pressure washing if the wood is in good condition.
• Application: Two coats of pigmented stain for optimal UV protection.

If the wood deck is severely deteriorated, the price can climb up to $6.00/sq ft due to the mechanical sanding and intensive washing required before staining.

Do it yourself: savings and preparation

DIY (do it yourself) can reduce the cost if you already have a pressure washer and a sander or can rent them. As a general rule:

• Deck in good condition: $1.25 to $1.75/sq ft (including tool rental and stain purchase).
• Neglected deck: $2.00 to $2.50/sq ft (additional time and effort for sanding and cleaning).

The main saving comes from the absence of labor costs, but preparation can be time-consuming.

Key steps for a DIY project

• Cleaning: Pressure washing to remove dirt and mildew.
• Drying: Allow the wood to dry for 24 to 48 hours before sanding.
• Sanding: Remove old finish layers.
• Staining: Apply a first coat, let it dry, then add a second for better protection.

Cost to stain railings

Railings often require more care due to details and moldings. Here are the usual rates:

• Deck in good condition: $4.00 to $12.00 per linear foot.
• Deteriorated or complex design deck: $6.00 to $16.00/linear foot.

Note that completely replacing wooden railings generally costs between $15.00 and $30.00/linear foot, depending on the design and material quality.

Average price for sealing

Choosing a sealant rather than a stain can reduce the bill. A sealant protects the surface without changing the wood's tint:

• Professional: $1.00 to $1.25/sq ft (including light sanding).
• DIY: Under $1.00/sq ft, if you do the sanding and application yourself.

However, stain remains more popular as it includes a pigment to block UV rays and offer a colored finish.

Why consider a composite deck?

Each year, more and more homeowners in Quebec are choosing composite decks from brands such as Fiberon, TimberTech, Trex, or TruNorth. Although initially more expensive to purchase, they eliminate the need for regular staining or sealing, thus reducing long-term maintenance costs.
