How much do contractors charge for subfloor replacement in Vancouver?

Subfloor replacement in Metro Vancouver typically costs $8-15 per square foot for materials and labor, with most homeowners paying $12-25 per square foot when you factor in related work like flooring removal and reinstallation.

The wide range depends heavily on your specific situation. Basic plywood subfloor replacement runs $8-12 per square foot if you're already doing a flooring renovation and the joists are in good condition. However, most subfloor replacements aren't straightforward — you're often dealing with water damage, structural issues, or access challenges that push costs higher.

Material costs in Vancouver are about 15-20% above national averages. You'll pay $35-50 per sheet for ¾" tongue-and-groove plywood or OSB subflooring, compared to $25-35 in other markets. Labor rates for skilled carpenters range from $65-85 per hour, with established contractors often charging $75-90 per hour for this type of precision work.

What drives costs up includes removing existing flooring first ($2-6 per square foot), dealing with squeaky or damaged floor joists underneath ($15-25 per square foot for joist repair), working in tight spaces like basements or crawl spaces, and addressing underlying moisture issues. Many Vancouver homes, especially older character houses and Vancouver Specials, have moisture problems that require additional waterproofing or drainage work before new subflooring goes in.

Typical project breakdown for a 200-square-foot bathroom subfloor replacement: flooring removal ($400-800), subfloor replacement ($1,600-2,400), joist repairs if needed ($600-1,200), and moisture barrier installation ($300-500). Total project cost often lands between $3,000-5,000 before new flooring goes back down.

When to replace vs. repair: If more than 30% of your subfloor shows water damage, soft spots, or delamination, replacement usually makes more sense than patching. In Vancouver's wet climate, addressing the root cause of moisture is critical — whether that's plumbing leaks, poor bathroom ventilation, or foundation drainage issues.

Professional guidance is essential for subfloor work. This isn't a DIY project unless you're experienced with structural carpentry. The subfloor supports your entire floor system, and improper installation can lead to squeaks, bounce, or even safety issues. Most contractors will want to inspect the joists and check for level before giving you a firm quote.

Next steps: Get quotes from at least three licensed contractors who can assess both the subfloor damage and any underlying structural issues. Expect the inspection to reveal additional work — it's rare that subfloor problems exist in isolation, especially in older Vancouver homes.
