Is it cheaper to repair or replace an aging cedar fence in Metro Vancouver?

As a general rule, if more than 30 to 40% of your cedar fence boards are damaged, rotted, or warped, full replacement is usually more cost-effective than piecemeal repairs. Below that threshold, targeted repairs can extend your fence's life by 5 to 10 years at a fraction of the replacement cost — but only if the posts and rails are still structurally sound.

The critical assessment starts with the posts. Posts are the structural foundation of any fence, and in Metro Vancouver's wet climate, post rot is the most common failure point. Push firmly against each post — if it rocks, wobbles, or feels soft at the base, that post needs replacement regardless of whether you repair or replace the fence. Individual post replacement costs $150 to $400 per post including removing the old post and concrete, digging a new hole, setting the new post in concrete with a gravel drainage bed, and reattaching rails and boards. If you have 3 or fewer rotted posts on a 100-foot fence, repair makes sense. If 5 or more posts are compromised, the cost of individual replacements starts approaching a full rebuild.

Board and panel replacement costs $8 to $20 per board for materials plus labour, depending on whether you're matching existing board widths and profiles. Matching aged cedar is tricky — new cedar boards will be noticeably lighter in colour than weathered boards, even with staining. After a year of weathering, the colour difference fades, but it will be visible initially. If your fence has a consistent weathered grey patina that you like, replacing scattered boards creates a patchwork look.

The Break-Even Calculation

Here's a practical way to decide. A full replacement of a 100-foot, 6-foot cedar privacy fence in Metro Vancouver runs $4,000 to $8,000 installed. Compare that to your repair estimate: if you need 4 posts replaced ($600 to $1,600), 20 boards replaced ($160 to $400 in materials plus labour), and professional staining of the entire fence to blend old and new ($200 to $500), you're looking at $1,000 to $2,500 in repairs. That's clearly cheaper than replacement — and if the remaining structure is solid, you'll get another 5 to 10 years from the fence.

But if you need 8 posts, 40+ boards, new rails in several sections, and the fence is already 15 to 20 years old, repair costs can hit $3,000 to $5,000 — at which point a full replacement at $4,000 to $8,000 gives you a brand-new fence with a 15 to 25 year lifespan, fresh gravel drainage at every post base, and proper modern fasteners. In Metro Vancouver's wet climate, a fence that's already showing widespread rot will continue to deteriorate even after repairs, so investing heavily in patching a fence that's past its prime is often throwing good money after bad.

After any repair or replacement, invest in professional staining and sealing every 2 to 3 years to protect your cedar from Metro Vancouver's relentless moisture. This $2 to $5 per linear foot maintenance cost is the single best investment you can make to maximize your fence's lifespan in this climate.
