Outdoor stairs in Vancouver face a lot of wear from constant rain, moisture, and changing temperatures. Over time, wood can rot, warp, or loosen, which creates both a safety risk and an eyesore.
Whether you want to try fixing them yourself or understand what a professional handyman does, this guide will walk you through how to repair or replace your exterior wood stairs safely and effectively.

- Ear protection if using power tools
Step 1: Inspect the Damage
Begin by checking each tread (the step you walk on) and stringer (the angled support underneath). Look for soft or discolored spots that feel spongy, which means rot has started. Pay special attention to where the stairs meet the landing or the ground since those areas stay damp the longest and often break down first.

Step 2: Remove the Old Wood
Use a drill or pry bar to take out old screws or nails and remove any damaged boards. Clear away all debris so you can inspect the structure underneath. If your stringers are still solid, you can reuse them. If not, trace one as a template before replacing it.

Step 3: Replace or Reinforce the Structure
Choose pressure-treated lumber when rebuilding or reinforcing your stairs. This type of wood is treated with preservatives that protect against moisture, insects, and rot, which is essential in Vancouver’s wet coastal climate.
You do not need a specific board size. The important thing is to use strong, stable wood that fits your existing stair design and can support regular use. If you are unsure about the right dimensions, your local building supplier or city office can confirm what works best for your setup.
Attach all new or reinforced components with exterior-grade screws or metal brackets for long-term strength and stability.

Step 4:Seal and Protect
Even pressure-treated wood needs a protective finish. Apply an exterior-grade sealer or urethane to prevent the wood from absorbing moisture or cracking under sunlight.
Why it matters: Moisture is the biggest reason outdoor stairs fail. A quality sealer helps the wood last longer and keeps it looking fresh.
Recommended option: A spar urethane like Minwax Helmsman offers a flexible, weather-resistant coating that expands and contracts with the wood, which is perfect for Vancouver’s damp winters and warm summers.

Step 5: Install New Treads
Lay your new boards evenly across the stringers, leaving a small gap between each one to allow rainwater to drain. Use corrosion-resistant screws, which last longer and make future maintenance easier. Check each step with a level so the rise and run feel even and comfortable.

Step 6: Clean Up and Inspect
After installing your new stairs, clear away any sawdust or scraps. Walk up and down each step to check for any movement, squeaks, or uneven spots. The stairs should feel solid and comfortable underfoot. A quick final inspection now will help prevent future repairs.
